NEW DELHI, — April 6, 2026 : The Defence Research and Development Organisation (DRDO) is preparing to initiate user-evaluation trials (UET) of the indigenous ‘Takshak’ electric heavyweight torpedo (EHWT) aboard the Indian Navy’s Kalvari-class submarines, with testing scheduled to commence in late 2026. The trials are intended to validate the system’s operational performance ahead of its planned induction into service. The Takshak torpedo has been developed by the Naval Science and Technological Laboratory (NSTL), a Visakhapatnam-based laboratory under DRDO. It is designed as a submarine-launched heavyweight torpedo capable of engaging both enemy submarines and surface vessels. The system is positioned as an advanced electric-propulsion derivative of the Varunastra torpedo, optimized for deployment from standard 533 mm submarine torpedo tubes. According to program details, the torpedo measures approximately 6.4 meters in length and weighs over 1,300 kilograms in its operational configuration. It is powered by an electric propulsion system using silver-oxide batteries, enabling low acoustic signature movement underwater. The estimated operational range is approximately 40 kilometers, with an operational depth capability of up to 400 meters.   Testing Roadmap and Schedule The evaluation process will follow a phased testing structure aligned with the refit schedules of the Kalvari-class submarines. Initial harbour-based trials will include both dry and wet testing procedures conducted while the submarine remains docked. These trials are intended to verify safe launch characteristics and ensure that torpedo deployment does not affect the submarine’s hull integrity, onboard sensors, or internal systems. Following successful harbour validation, dynamic sea trials are scheduled for late 2026. During this phase, the torpedo will be deployed under operational conditions at varying depths and speeds. A key focus of this stage will be the validation of the fibre-optic wire guidance system, particularly its performance during high-speed underwater maneuvers. A live-fire test phase is planned for 2027. This stage will involve the launch of a fully armed torpedo against a decommissioned ship or designated underwater target to assess warhead effectiveness and overall system reliability.   Guidance, Navigation, and Control Systems The Takshak is equipped with a Ring Laser Gyroscope (RLG)-based inertial navigation system (INS), supported by satellite-based inputs from GPS and India’s NavIC navigation system. For tactical guidance, the torpedo uses a fibre-optic wire link, allowing real-time data exchange between the submarine and the weapon. This fibre-optic guidance enables sonar operators onboard the submarine to transmit course corrections and targeting updates during the engagement. In the event that the wire link is severed, the torpedo is programmed to transition into an autonomous homing mode, allowing it to continue toward the target using onboard sensors. The system also incorporates advanced sonar capabilities and resistance to electronic countermeasures, improving target acquisition and engagement reliability in contested environments.   Launch Mechanism and Submarine Integration The Takshak torpedo is deployed using a “swim-out” launch mechanism, which allows the weapon to exit the submarine’s torpedo tube under its own propulsion rather than being expelled using compressed air. This method reduces the acoustic signature associated with launch, supporting the stealth characteristics of the submarine. Integration of the torpedo with the Kalvari-class submarines is being carried out in coordination with ongoing submarine refit programs. During the refit of INS Kalvari, the lead vessel of the class, hardware required for the torpedo’s launch system is being installed along with other upgrades. To support system integration, the Ministry of Defence signed a contract valued at ₹877 crore (approximately $102.4 million) with France’s Naval Group on December 30, 2024. The agreement covers the integration of the Takshak torpedo with the Submarine Tactical Integrated Combat System (SUBTICS), which is deployed across the Kalvari-class fleet. The integration ensures compatibility between the torpedo and the submarine’s combat management system, enabling coordinated target tracking, fire control, and weapon deployment. The effort is being undertaken jointly by the Indian Navy, DRDO, and Naval Group.   Platform and Production Details The Kalvari-class submarines, also known as Scorpene-class submarines, are being constructed in India by Mazagon Dock Shipbuilders Limited (MDL) under Project 75. These submarines form a key component of the Indian Navy’s conventional underwater fleet. The Takshak torpedo is intended to be manufactured by Bharat Dynamics Limited (BDL) following successful completion of trials and acceptance into service. As of late 2024, the torpedo had completed required redesign work, including modifications to its tail section, positioning it for the upcoming evaluation phase. Separate development activity related to an extended-range or deeper-strike variant of the EHWT has been reported, though it is not part of the current trial program for the Kalvari-class submarines.   Strategic Context The development and planned induction of the Takshak torpedo form part of India’s broader efforts to enhance indigenous defence manufacturing under the “Aatmanirbhar Bharat” initiative. The system is expected to reduce dependence on imported heavyweight torpedoes while strengthening the operational capabilities of the Indian Navy’s submarine fleet.

NEW DELHI, — April 6, 2026 : India is set to carry out a two-day series of Global Navigation Satellite System (GNSS) jamming trials in the Bay of Bengal from April 11 to April 12, 2026, as part of ongoing efforts to strengthen its electronic warfare (EW) capabilities. The exercise will focus on evaluating ground-based systems designed to disrupt satellite navigation signals, including GPS and other GNSS networks, within designated maritime zones. According to official notifications, including a Notice to Airmen (NOTAM), the trials will be conducted under controlled conditions to ensure the safety of civil aviation and maritime traffic operating in the region during the specified period.   Focus on Denial of Satellite-Based Navigation The primary objective of the trials is to assess the effectiveness of GNSS jamming in denying Positioning, Navigation, and Timing (PNT) services in operational scenarios. PNT data is a critical component of modern military operations, supporting navigation, targeting, synchronization, and coordination across platforms. The systems under evaluation are intended to degrade or deny access to satellite-based navigation for hostile assets, including precision-guided munitions (PGMs), unmanned aerial vehicles (UAVs), and other systems dependent on network-centric operations. By limiting access to reliable PNT data, the trials aim to test India’s ability to operate in an environment where satellite navigation is contested or unavailable.   Operational Relevance in Maritime Domain The Bay of Bengal has been selected as the test location due to its relevance to India’s maritime security environment and its proximity to key operational areas within the Indian Ocean Region (IOR). Conducting trials in this setting allows for realistic assessment of system performance against simulated aerial and maritime targets. Defense agencies will monitor multiple parameters during the exercise, including signal disruption range, interference density, system stability, and overall effectiveness of the jamming equipment in a dynamic operational environment.   Strategic and Deterrence Implications The trials form part of a broader effort to enhance India’s preparedness for operations in electronically contested battlespaces. By demonstrating the capability to disrupt satellite navigation systems, India aims to improve the survivability of its naval and coastal assets and strengthen its defensive posture in the IOR. The ability to deny or degrade GNSS signals is increasingly viewed as a key element of modern deterrence, particularly in scenarios involving high-precision weapons and autonomous systems.   Alignment with Evolving Threat Environment The initiative aligns with global trends in electronic warfare, where interference with satellite navigation systems has become more frequent in conflict zones. Incidents of GPS jamming and spoofing have been reported in various regions over the past two years, including areas near India’s western and northeastern borders. In response, India has expanded its investments in EW technologies, including ground-based VHF–UHF communication jammers and integrated mobile systems such as the Samyukta platform. These systems are designed to disrupt enemy communications and command networks in addition to navigation signals.   Role of Indigenous Systems and Industry The GNSS jammer systems being tested are part of India’s broader push to develop an indigenous electronic warfare ecosystem. Key organizations involved in this effort include the Defence Research and Development Organisation (DRDO), Bharat Electronics Limited (BEL), and private sector defense firms. The trials are expected to provide operational data that will support further development and refinement of domestically produced EW systems, reducing reliance on imported technologies. India’s use of its regional navigation satellite system, NavIC, also forms part of its strategy to ensure continuity of navigation services for its own forces in environments where global GNSS signals may be disrupted.   Continuity of Electronic Warfare Development India has previously conducted electronic warfare exercises and continues to invest in counter-GNSS technologies. The April 11–12 trials represent a continuation of these efforts, with a focus on improving resilience, operational capability, and integration of EW systems across different domains. No specific technical details regarding the jammer systems or exact trial coordinates have been disclosed in the public domain. The exercise will remain under close observation by defense authorities throughout its duration.

Visakhapatnam, — April 5, 2026 : Defence Minister Rajnath Singh on April 3, 2026, laid the foundation stone for a Large Cavitation Tunnel (LCT) facility at the Naval Science and Technological Laboratory (NSTL), a key laboratory of the Defence Research and Development Organisation (DRDO), in Visakhapatnam. The project is intended to expand India’s domestic capacity for advanced hydrodynamic testing of naval platforms and underwater systems. The Large Cavitation Tunnel is designed as a state-of-the-art facility capable of simulating complex hydrodynamic conditions encountered by submarines and surface ships. It features an integrated configuration that supports both closed-loop simulations for submarine studies and free surface simulations for surface vessels within a single setup. This combined capability is expected to enable comprehensive testing of propellers, torpedoes, and other critical underwater components. Once operational, the facility will allow detailed validation of hydrodynamic designs and propulsion systems for a wide range of naval platforms, including destroyers and aircraft carriers. It will support studies of cavitation effects—pressure-induced vapor bubble formation and collapse—which are critical in determining propulsion efficiency, structural durability, and acoustic performance of naval systems.   Focus on Indigenous Capability and Data Security The development of the LCT addresses a longstanding gap in India’s defence testing infrastructure. Until now, advanced hydrodynamic testing for high-end naval systems has often been conducted at facilities in the United States, France, and Russia, or through limited domestic capabilities. This reliance raised concerns related to data security and restricted the ability to carry out full-scale validation of sensitive designs within the country. With the establishment of the LCT, India aims to reduce dependence on foreign testing infrastructure and enable end-to-end indigenous design, development, and validation of naval equipment, systems, and sub-systems. The project has been sanctioned by the Government of India and is being executed in turnkey mode with international technical collaboration.   Impact on Naval Design and Underwater Warfare Systems The facility is expected to contribute to the development of quieter propulsion systems for submarines by enabling precise analysis of cavitation and fluid dynamics. Reduced acoustic signatures will improve stealth characteristics and enhance sonar performance. In addition, the LCT will support improvements in warship efficiency and durability and facilitate the development of next-generation torpedoes and underwater weapons. NSTL, which is responsible for research and development of torpedo systems, underwater mines, decoys, and autonomous underwater vehicles (AUVs), will integrate the new facility into its ongoing programs. During the visit, Defence Minister Singh was briefed by DRDO Chairman Dr. Samir V. Kamat on current and planned initiatives. He also visited the Seakeeping and Manoeuvring Basin and observed demonstrations of underwater systems, including torpedoes, naval mines, decoys, and a swarm of man-portable AUVs. The minister additionally reviewed spin-off technologies developed by the Naval Systems Materials cluster following Operation Sindoor and examined ongoing work in lithium-ion battery development for defence applications.   Official Statements and Strategic Context Addressing scientists and personnel at NSTL during the foundation stone laying ceremony, Singh stated that the LCT is intended to function as an enabling system for future naval engineering efforts. He noted that the facility would strengthen work on propulsion systems, noise reduction, and stealth technologies, and serve as a foundational infrastructure for submarine and ship design. He also highlighted that, despite progress in developing defence systems domestically, India had previously depended on foreign facilities for critical testing. According to Singh, the commissioning of the LCT is expected to change this situation and contribute to strengthening India’s position in naval technology development through indigenous resources. The Defence Minister commended NSTL for its contributions to advancing underwater warfare capabilities and self-reliance in defence research, noting that its progress reflects ongoing efforts to prepare for future operational requirements.   Ceremony and Related Developments The foundation stone laying ceremony was attended by senior defence leadership, including Chief of Defence Staff General Anil Chauhan, Chief of the Naval Staff Admiral Dinesh K. Tripathi, and Flag Officer Commanding-in-Chief of the Eastern Naval Command Vice Admiral Sanjay Bhalla. The event coincided with the commissioning of the stealth frigate INS Taragiri into the Indian Navy at the Naval Dockyard in Visakhapatnam on the same day, April 3, 2026. Both developments form part of broader initiatives to strengthen indigenous naval design, testing infrastructure, and shipbuilding capabilities.   Project Status No official timeline for completion of the Large Cavitation Tunnel or details of the project cost have been disclosed. The facility is expected to support long-term development of India’s shipbuilding ecosystem and enhance domestic capabilities in naval research and engineering under the self-reliance initiative.

New Delhi, — April 5, 2026 : The Ministry of Defence (MoD) has initiated a program to indigenously design, develop, and procure 1,000-kg aerial bombs for the Indian Air Force (IAF), issuing a formal Expression of Interest (EoI) under the Defence Acquisition Procedure (DAP) 2020. According to official details, the EoI covers the development of heavy general-purpose bombs comparable to the Mk-84 class currently in service with the IAF. The ministry has outlined plans to procure an initial batch of approximately 600 such bombs following successful development and evaluation.   Program Structure and Procurement Framework The project will be executed in two phases under established procurement categories. The first phase falls under the ‘Make-II’ category, which is industry-funded. Selected Indian entities will be responsible for designing and developing the bombs, including associated tail units and supporting equipment. A minimum of 50 percent indigenous content has been mandated during this stage. Development agencies will be required to produce six prototypes, including both live and inert variants. These prototypes will undergo Single-Stage Composite Trials (SSCT), along with comprehensive flight and drop testing from specified Indian Air Force aircraft at designated testing ranges. Data from these trials will be used to refine Preliminary Staff Qualitative Requirements (PSQRs) into formal Air Staff Qualitative Requirements (ASQRs). The second phase will proceed under the ‘Buy (Indian-IDDM)’ category—Indigenously Designed, Developed, and Manufactured. A commercial Request for Proposal (RFP) will be issued to qualifying agencies for the production and supply of the 600 bombs after successful completion of development and trials. The overall timeline from the issuance of the EoI to the signing of the final procurement contract is estimated at approximately 2.5 years.   Technical Characteristics and Operational Role The proposed 1,000-kg (approximately 2,000-pound) aerial bomb is categorized as a high-calibre munition designed to deliver substantial blast effects, natural fragmentation, and significant peak over-pressure (PoP). Such munitions are typically employed against high-value and hardened targets, including underground bunkers, reinforced concrete structures, bridges, aircraft runways, and large ammunition storage facilities. The EoI specifies that the bombs and their associated systems must be compatible with both Russian-origin and Western-origin aircraft in the IAF inventory. This includes integration across platforms such as the Su-30 MKI, Rafale, and the indigenous Tejas, without requiring major modifications.   Current Dependence and Strategic Rationale At present, the Indian Air Force procures Mk-84 class general-purpose bombs from foreign original equipment manufacturers (OEMs). The move toward indigenous production is aimed at reducing dependence on external suppliers and ensuring availability during extended operational scenarios. The requirement also reflects operational lessons observed in recent conflicts in the Middle East, where 2,000-pound class bombs have been widely used against fortified and deeply buried targets. The development of a domestic capability is intended to support long-range strike operations and improve logistical resilience.   Industry Participation and Collaboration Participation in the EoI is open to eligible Indian entities, including private sector companies and micro, small, and medium enterprises (MSMEs). The MoD has permitted foreign collaboration through joint ventures or technology transfer arrangements, provided that the primary applicant complies with indigenous design and manufacturing requirements. The initiative forms part of ongoing efforts to strengthen domestic defence manufacturing capabilities and aligns with broader policy objectives focused on indigenisation under the DAP 2020 framework.

NASHIK, INDIA — April 4, 2026 : Hindustan Aeronautics Limited (HAL) has received foundational material kits from Russia for the licensed production of 12 Su-30MKI multi-role fighter aircraft at its Nashik division, marking the restart of assembly activities under a contract aimed at reinforcing the Indian Air Force (IAF) combat fleet. The delivery supports a ₹13,500 crore (approximately $1.6 billion) agreement signed on December 12, 2024, between India’s Ministry of Defence (MoD) and HAL. According to officials, the arrival of these kits enables HAL to begin assembly operations, with the company maintaining its target to deliver all 12 aircraft to the IAF by the end of 2026.   Production Restart and Facility Role HAL’s Nashik facility in Maharashtra will serve as the lead integrator for the program, carrying out final assembly, integration, and testing of the aircraft. The production line had remained inactive for over 12 months prior to the contract’s finalization and is now being reactivated to execute the order. The facility has extensive experience with Russian-origin platforms and has previously produced 222 Su-30MKI aircraft under license since 2004. In total, HAL has manufactured and supported nearly 1,000 aircraft across multiple programs, including earlier MiG variants.   Indigenous Content and Industrial Contribution The 12 aircraft will incorporate a reported 62.6 percent indigenous content, reflecting ongoing efforts under India’s Aatmanirbhar Bharat initiative to increase domestic manufacturing in defense production. Key areas of indigenization include: Mission systems and avionics: Integration of Indian-developed mission computers, avionics suites, and communication systems supplied by domestic industry partners. Engine manufacturing: The AL-31FP turbofan engines are being produced at HAL’s Koraput division, with increasing use of locally sourced raw materials and forgings. Weapons integration: Compatibility with indigenous systems such as the Astra beyond-visual-range (BVR) air-to-air missile and the BrahMos supersonic cruise missile. The higher level of local content compared to earlier production batches indicates progressive replacement of imported components with domestically manufactured systems.   Fleet Role and Operational Context The Su-30MKI remains the backbone of the IAF’s combat fleet. India has procured a total of 272 aircraft, of which 50 were delivered directly by Russia, while the remainder were assembled by HAL from completely knocked-down (CKD) kits. Currently, the IAF operates approximately 30 to 31 fighter squadrons, below its sanctioned strength of 42. The additional 12 aircraft are intended to serve two primary purposes: Attrition replacement: Replacing aircraft lost in accidents over the past decade. Capability bridging: Addressing squadron shortages amid delays in the Tejas Mk-1A program linked to international engine supply constraints. The Su-30MKI fleet accounts for nearly 60 percent of India’s combat aircraft inventory, with around 270 aircraft currently in service.   Technical Characteristics The Su-30MKI is a twin-engine, two-seat heavy air superiority fighter designed for both air-to-air and air-to-ground missions. Its core specifications include: Maximum speed: Mach 2.0 (approximately 2,100 km/h) Combat radius: 1,300 km without aerial refueling Radar: N011M Bars passive electronically scanned array (PESA) Payload capacity: Up to 8,000 kg across 12 hardpoints   Upgrade Path and “Super Sukhoi” Program The newly produced aircraft are expected to incorporate elements aligned with the planned “Super Sukhoi” upgrade program, valued at approximately ₹60,000 crore. This modernization effort will retrofit the existing fleet with: Virupaksha active electronically scanned array (AESA) radar Advanced electronic warfare (EW) suites New digital cockpit systems developed by the Defence Research and Development Organisation (DRDO) and Indian private sector partners The program aims to extend the operational lifespan of the Su-30MKI fleet by 20 to 30 years.   Strategic and Industrial Outlook The delivery of material kits reflects the continuation of Indo-Russian defense cooperation under the licensed production framework established in 2000. At the same time, the increased indigenous content highlights India’s gradual shift toward greater self-reliance in defense manufacturing. Following completion of this batch, HAL’s Nashik facility is expected to transition toward large-scale modernization work under the Super Sukhoi program, alongside ongoing maintenance, repair, and overhaul (MRO) activities for the existing fleet. No detailed breakdown of delivery milestones for individual aircraft has been released. However, officials indicate that production timelines remain aligned with the scheduled completion by December 2026.

NEW DELHI — April 3, 2026 : The Indian Air Force (IAF) has initiated a new procurement and development program for an Air-Dropped Canisterised Swarm (ADC-S) system, advancing its push toward autonomous, long-range strike capabilities in contested environments. The project is being pursued under the Make-II category of the Defence Acquisition Procedure (DAP) 2020, with Air Headquarters’ Directorate of Operations (Remote) designated as the nodal agency. The program, referenced as CF No/ Air HQ/C 18488/69/DAD, focuses on the design, development, and manufacture of an indigenised, multi-use swarm munition system capable of engaging high-value and time-sensitive targets deep inside adversary territory.   Deployment Concept and Launch Platforms The ADC-S system will be deployed using a palletised weapon airdrop mechanism from the IAF’s existing transport aircraft fleet, including the C-17 Globemaster III, C-130J Super Hercules, and C-295. This approach allows the use of transport aircraft as stand-off launch platforms rather than relying on frontline fighter jets. The system is designed to achieve a minimum operational range of approximately 500 kilometers from the point of release. This stand-off distance enables launch aircraft to remain outside hostile air defence engagement zones, particularly in anti-access/area denial (A2/AD) environments. The final range parameter will be confirmed following feasibility studies.   System Architecture and Swarm Composition Each air-dropped canister will contain a minimum of six to eight swarm munitions, with the possibility of higher payload configurations depending on system design. Once deployed, the canister disperses these munitions, which operate as a coordinated swarm. Individual swarm units are required to achieve cruise speeds between 350 and 400 km/h and carry a munition payload of at least 30 kilograms. The design also incorporates modularity, allowing integration of additional sensors or mission-specific payloads alongside the primary munition package.   Autonomy, Navigation, and Precision Requirements The ADC-S system is designed to operate in contested electromagnetic environments, including areas where Global Navigation Satellite Systems (GNSS) may be denied or degraded due to electronic warfare. To address this, the system incorporates advanced artificial intelligence and autonomous capabilities. These include autonomous navigation, target search, detection, identification, and engagement decision-making. The swarm must also be capable of continuing mission execution even in the absence of communication links. Precision requirements specify a Circular Error Probable (CEP) of 5 meters or less, supported by terminal guidance systems to ensure accuracy against designated targets.   Operational Role and Battlefield Application In operational scenarios, the ADC-S is intended to provide the IAF with a stand-off strike capability against high-value, time-sensitive targets such as radar installations, surface-to-air missile systems, command and control nodes, and other critical infrastructure. The use of swarm tactics enables multiple munitions to be deployed simultaneously, creating a saturation effect that can overwhelm adversary air defence systems. This distributed attack profile is particularly relevant in heavily defended environments where conventional strike aircraft may face higher risk. The reliance on autonomous operation further enhances survivability and mission reliability in conditions where electronic warfare may disrupt communications or navigation systems.   Industrial Participation and Procurement Pathway The project is being executed under the Make-II category, which requires Indian industry to undertake design and development using its own funding. The initiative mandates a minimum indigenous content of 50 percent, aligning with the government’s Atmanirbhar Bharat policy for self-reliance in defence manufacturing. Following successful prototype development and validation, the program is expected to transition to procurement under the “Buy Indian–IDDM” (Indigenously Designed, Developed and Manufactured) category. The IAF has indicated an anticipated minimum order quantity ranging between 1,000 and 2,000 units, subject to the outcomes of feasibility studies and recommendations from the Project Facilitation Team.   Industry Engagement and Timeline A project questionnaire was uploaded on the Make in India Defence Production portal on 1 April 2026. Indian companies interested in participating in the program have been invited to submit responses by 30 April 2026. Further refinement of system specifications and preliminary service qualitative requirements will be carried out following industry consultations and feasibility assessments. The ADC-S program represents a step in expanding the IAF’s capability portfolio in autonomous warfare systems, with a focus on extending operational reach, reducing risk to manned platforms, and enabling precision engagement in contested airspace.

NEW DELHI — April 2026 : The Indian Air Force (IAF) has initiated a new development program for an Unmanned Combat Search and Rescue (CSAR) aircraft under the Make-I sub-category of the Defence Acquisition Procedure (DAP) 2020, marking a step toward autonomous recovery capabilities in high-risk operational environments. The project, referenced as CF No/ Air HQ/C 18488/69/DAD and managed by the Directorate of Operations (Remote) at Air Headquarters, seeks to design, develop and manufacture a runway-independent unmanned platform capable of recovering downed aircrew in hostile territory without exposing additional personnel or manned aircraft to risk.   Operational Requirement and Role Expansion The IAF’s requirement focuses on deploying an unmanned system for Combat Search and Rescue missions in contested airspace where conventional helicopter-based recovery operations may be considered too hazardous. By removing onboard crew, the platform is intended to conduct extractions in high-threat zones while reducing operational risk. In addition to personnel recovery, the aircraft is expected to perform logistics missions, including the transport of supplies and equipment to forward operating bases, remote areas and terrain inaccessible to conventional aircraft. The system is designed to operate in challenging environmental conditions, including extreme temperatures and degraded visibility scenarios such as whiteout conditions in snow-bound regions and brownout conditions in desert or dusty environments.   Technical Specifications and Performance Parameters According to the project brief, the unmanned CSAR platform must meet defined operational and performance criteria. The system is required to support a minimum payload capacity of 400 kilograms, enabling it to carry at least four personnel or accommodate medical evacuation stretchers. The aircraft must have a minimum radius of action of 200 kilometers and be capable of maintaining a loiter time of at least 45 minutes over the target area. Higher operational ranges are considered desirable. Altitude requirements specify operational capability from sea level up to 16,000 feet AMSL, with a desirable ceiling of 20,000 feet AMSL to support high-altitude missions. A key requirement is runway independence, with the platform required to take off and land on unprepared or unpaved surfaces. Additionally, it must maintain stability during operations in wind conditions of up to 30 knots, with a gust tolerance of ±10 knots during takeoff and landing phases.   Navigation, Autonomy and Mission Systems The unmanned system will incorporate multiple navigation frameworks, including Global Navigation Satellite Systems (GNSS), IRNSS, and NAVIC. Importantly, the platform must retain full operational capability in GNSS-denied environments or electronically contested environments. Autonomy is a central feature of the program. The aircraft must be capable of fully automated takeoff, navigation and landing without direct human intervention. For its primary mission, the system must autonomously search, detect, identify and land near downed personnel by integrating with Emergency Locator Transmitters (ELTs).   Indigenous Development Framework The project is being executed under the Make-I category, which provides government funding support for prototype development. It aligns with India’s Atmanirbhar Bharat initiative aimed at increasing self-reliance in defense manufacturing. Under program requirements, the platform must achieve a minimum indigenous content level of 50 percent, covering design, materials, subsystems and software. Following prototype development, certification by CEMILAC and subsequent field trials, the Ministry of Defence plans to procure an initial batch of approximately 10 units. The acquisition will be conducted under the Buy Indian–IDDM category.   Industry Participation and Timeline Indian defense companies meeting the eligibility criteria outlined in DAP 2020 have been invited to participate in the program. Desirable qualifications include experience in aviation manufacturing, maintenance, repair and overhaul (MRO), logistics support, and familiarity with certification and quality assurance processes under DGAQA and CEMILAC. Interested entities are required to submit proposals along with responses to a detailed questionnaire by April 30, 2026, to the designated nodal directorate at Air Headquarters. The IAF stated that detailed project specifications and preliminary staff qualitative requirements will be refined through industry consultations and feasibility assessments as the program progresses.

VISAKHAPATNAM, — April 3, 2026 : India on Friday commissioned its third nuclear-powered ballistic missile submarine (SSBN), INS Aridhaman, into the Indian Navy at a ceremony held in Visakhapatnam and presided over by Defence Minister Rajnath Singh. The induction marks a continued expansion of India’s sea-based nuclear deterrent and strengthens the maritime leg of its nuclear triad. The submarine, designated S4 under the classified Advanced Technology Vessel (ATV) program, is the third vessel in the Arihant-class series and the first of an enlarged subclass with improved design and capabilities. Its commissioning coincided with the induction of the stealth frigate INS Taragiri, reflecting ongoing efforts by the Ministry of Defence to expand naval capacity through indigenous platforms.   Platform Development and Construction INS Aridhaman was constructed at the Ship Building Centre (SBC), Visakhapatnam, with fabrication support from Larsen & Toubro. The keel was laid around 2018, and the submarine was launched on November 23, 2021. It completed its sea trials by late 2025 before being cleared for operational service. The vessel has a displacement of approximately 7,000 tonnes, making it larger than earlier Arihant-class submarines such as INS Arihant and INS Arighaat, which displace around 6,000 tonnes. It measures about 130 metres in length with a beam of 11 metres and incorporates a more streamlined hull design aimed at improving hydrodynamic efficiency and reducing acoustic signature.   Propulsion and Performance The submarine is powered by an 83 MW Compact Light Water Reactor, an upgraded pressurised water reactor developed by the Bhabha Atomic Research Centre (BARC). The reactor enables extended submerged endurance and contributes to lower detectability compared to earlier configurations. INS Aridhaman is fitted with a seven-blade propeller and is capable of speeds ranging from 12 to 15 knots on the surface and up to 24 knots when submerged. The nuclear propulsion system allows the submarine to remain underwater for prolonged periods without surfacing, enhancing operational survivability.   Armament and Combat Systems The submarine is equipped with eight vertical launch system (VLS) tubes located in its missile compartment, doubling the missile capacity compared to earlier boats in the class. It can carry: Up to 24 K-15 (Sagarika) submarine-launched ballistic missiles (SLBMs) with a range of 750 km, or Up to 8 K-4 SLBMs with a range of approximately 3,500 km The platform has also been designed to integrate future K-5 SLBMs, which are currently under development and expected to have a range of around 6,000 km. In addition to ballistic missile capability, INS Aridhaman is fitted with six 533 mm torpedo tubes and is estimated to carry up to 30 munitions, including torpedoes, cruise missiles, or naval mines. The submarine is equipped with indigenous sensor and combat systems, including the USHUS integrated sonar suite and the Panchendriya unified submarine control and underwater communication system.   Operational Role and Basing INS Aridhaman will operate under India’s Strategic Forces Command and is expected to be based at Project Varsha, a high-security naval facility with underground submarine pens near Visakhapatnam. With the induction of the third SSBN, the Indian Navy improves its ability to maintain continuous at-sea deterrence, ensuring that at least one nuclear-armed submarine remains on patrol while others undergo maintenance or transit.   Fleet Integration and Strategic Context INS Aridhaman joins INS Arihant (commissioned in 2016) and INS Arighaat (inducted on August 29, 2024). This marks the first time India operates three Arihant-class SSBNs simultaneously. India remains among a limited group of countries operating nuclear-powered submarines, alongside the United States, Russia, China, the United Kingdom, and France. A fourth submarine of similar configuration, expected to be named INS Arisudan, is currently under construction and is projected to enter service around 2027. In parallel, India is progressing toward the development of the next-generation S5-class submarines, expected to displace around 14,000 tonnes.   Concurrent Commissioning of INS Taragiri Alongside INS Aridhaman, the Indian Navy commissioned INS Taragiri, an advanced stealth frigate built by Mazagon Dock Shipbuilders Limited (MDL) under Project 17A. The 6,670-tonne frigate is equipped with a Combined Diesel or Gas (CODOG) propulsion system and features a modern weapons suite, including supersonic surface-to-surface missiles and medium-range surface-to-air missile systems.   Program Continuity Officials indicated that the expanded missile capacity, improved propulsion system, and reduced acoustic signature of INS Aridhaman contribute to strengthening the credibility of India’s sea-based deterrent. Development work under the ATV program continues at the Ship Building Centre as part of India’s long-term indigenous submarine construction roadmap.

NEW DELHI, — April 2, 2026 : The Ministry of Defence (MoD) has initiated a major procurement process for more than 200 New Generation Air Defence Gun (ADG-NG) systems for the Indian Army, issuing a Request for Information (RFI) to industry. Vendors have been asked to submit technical and product responses by June 11, 2026, marking the early stage of a program aimed at strengthening India’s short-range air defence capabilities. The planned acquisition forms a core component of Mission Sudarshan Chakra, a long-term initiative designed to establish an artificial intelligence-enabled, multi-layered national air and missile defence architecture by 2035. The program integrates sensors, command-and-control networks, and weapon systems across the Army, Air Force, and Navy, with gun-based systems forming a key layer for close-in protection.   Operational Background and Threat Assessment The requirement for ADG-NG systems is based on operational lessons drawn from Operation Sindoor conducted in May 2025. During that period, adversaries deployed electrically powered drone swarms along India’s western front for surveillance and precision targeting of civilian and military infrastructure. These drones, including commercial and improvised platforms, presented detection challenges due to their low radar cross-section and minimal infrared signatures. The experience highlighted limitations in existing air defence systems, particularly against low-cost, small, and slow-moving aerial threats. In response, the ADG-NG systems are required to detect, recognise, identify, track, and engage a wide spectrum of aerial targets. These include conventional threats such as fixed-wing aircraft, helicopters, and cruise missiles, as well as unconventional platforms like micro and mini unmanned aerial systems, para-motors, paragliders, and micro-light aircraft. The systems are also expected to handle high-performance targets, including fighter aircraft such as the Dassault Rafale, alongside small commercial drones like the DJI Mavic Pro 3.   Technical Specifications and System Requirements According to the RFI, the ADG-NG will be a vehicle-mounted or towed platform equipped with advanced automation and fire control technologies. Key operational and technical parameters include: The system must achieve a minimum firing range of 4,000 metres and an engagement altitude of at least 2,500 metres. It is required to sustain a rate of fire exceeding 300 rounds per minute and engage targets travelling at speeds up to 500 metres per second. The guns will use programmable smart ammunition, including pre-fragmented and proximity-fused rounds, along with conventional high-explosive tracer ammunition. All ammunition must incorporate a self-destruct mechanism to minimise collateral damage and maintain a minimum shelf life of 10 years. Each system will be fitted with an integrated Electro-Optical Fire Control System (EOFCS) capable of autonomous, all-weather, day-and-night operation. This includes target acquisition, tracking, and engagement without continuous operator input. Operational requirements specify the inclusion of an autoloader system manageable by no more than two personnel. The platforms must also support silent operations through onboard power solutions such as generators, batteries, or external mains supply to reduce acoustic detection.   Industrial Participation and Competing Systems Three Indian defence manufacturers are expected to participate in the ADG-NG program based on their existing capabilities and involvement in similar projects. Larsen & Toubro (L&T) is offering its Sudarshan Close-in Weapon System (CIWS), which incorporates a 3D Active Electronically Scanned Array (AESA) radar and is designed for autonomous tracking and engagement, including high-altitude operations. Bharat Heavy Electricals Limited (BHEL), in partnership with Italy-based Leonardo S.p.A., is proposing a system focused on high fire density. This configuration is intended for point defence roles, particularly for protecting critical infrastructure and high-value assets. The partnership builds on ongoing collaboration between the two companies in gun and fire control system development. Advanced Weapons and Equipment India Limited (AWEIL), headquartered in Kanpur, is presenting an upgraded version of the legacy Bofors L-70 air defence gun. The proposed system incorporates modern electronics, digital fire control systems, and improved radar integration.   Indigenous Content and Procurement Framework The MoD has stipulated that the ADG-NG systems must achieve a minimum of 50 percent indigenous content based on cost. This requirement aligns with the government’s Atmanirbhar Bharat policy, which prioritises domestic manufacturing, technology transfer, and local supply chain development in defence procurement. The systems are expected to feature modular architecture to ensure compatibility with existing Indian Army radar, communication, and navigation systems. The program also emphasises scalability and future upgrades as part of the broader integrated air defence framework.   Modernisation Context and Previous Efforts The ADG-NG program is part of ongoing efforts to replace legacy air defence guns currently in service, including the ZU-23-2 twin-barrel autocannons and mechanically operated L-70 systems. These older platforms have limited capability against emerging threats such as drone swarms and precision-guided munitions. The current RFI builds on earlier procurement initiatives. In October 2022, the MoD issued a Request for Proposal (RFP) for 220 towed air defence guns under the Buy and Make (Indian) category, also requiring 50 percent indigenous content. The ADG-NG program represents a shift toward more advanced, vehicle-mounted systems with higher levels of automation and integration.

BENGALURU, — April 2, 2026 : Hindustan Aeronautics Limited (HAL) has invoked contractual penalty provisions against GE Aerospace over delays in the supply of F404-IN20 engines, a key component of the Light Combat Aircraft (LCA) Tejas Mk1A programme for the Indian Air Force (IAF). The penalties, structured as liquidated damages, are being applied for each engine delivered beyond agreed timelines under the engine procurement contract signed in 2021. HAL officials confirmed that the contract explicitly mandates financial penalties for schedule slippages, and deductions are being made as per the agreed terms.   Contract Details and Delivery Status The 2021 agreement between HAL and GE Aerospace covers the supply of 99 F404-IN20 engines, valued at approximately $716 million (around $1 billion in broader programme estimates), intended to power 83 Tejas Mk1A aircraft ordered by the IAF. Deliveries, initially expected earlier, formally commenced in March 2025. As of early April 2026, HAL has received five engines. A sixth engine has been handed over in the United States and is expected to reach India by the end of April. HAL Chairman and Managing Director D. K. Sunil stated that GE Aerospace has committed to delivering at least 20 engines during the second half of calendar year 2026, between June and December. He described this projection as a “pessimistic” estimate, noting that the manufacturer has indicated the possibility of exceeding that figure. A follow-on agreement signed in November 2025 provides for an additional 113 F404-IN20 engines, including spares and modules, to support production of 97 more Tejas Mk1A aircraft. Deliveries under this second contract are scheduled from 2027 through 2032.   Impact on Tejas Mk1A Production In February 2021, the Ministry of Defence awarded HAL a ₹48,000 crore contract to manufacture 83 Tejas Mk1A jets, including 73 fighter variants and 10 trainers. While HAL’s production lines remain active and multiple airframes have been completed, final assembly has been constrained by the shortage of engines. HAL currently has five aircraft fitted with engines and expects to have six aircraft integrated with Category-A engines by the end of April 2026. The company is targeting delivery of more than 20 Tejas Mk1A jets by December 2026, subject to completion of ongoing testing milestones. These include radar integration, avionics validation, and simultaneous missile-firing trials from twin launch pods. A comprehensive programme review scheduled for May 2026 will assess readiness prior to formal aircraft deliveries to the IAF.   Financial and Contractual Implications The liquidated damages clause allows HAL to deduct a percentage of the value of each delayed engine. However, the delays have also created downstream contractual obligations. HAL is liable to pay penalties to the Indian Air Force for delays in delivering completed aircraft under its separate contract. HAL officials emphasized that while domestic production infrastructure is fully prepared, engine availability remains the primary constraint affecting delivery timelines.   IAF Monitoring and Fleet Status The Indian Air Force is closely monitoring developments related to engine deliveries and programme progress. The planned review in May 2026 is expected to evaluate the overall status of the Tejas Mk1A programme before acceptance of aircraft. Separately, the existing Tejas Mk1 fleet, which had been grounded for approximately two months for routine maintenance checks and software updates related to its braking system, has been cleared to resume operations. The fleet is expected to return to active flying status by the second week of April 2026.   Supply Chain Challenges GE Aerospace has attributed earlier delays to global supply chain constraints, which affected production schedules and delivery commitments. HAL has reiterated that its assembly lines are ready to scale output once engine supplies stabilize, indicating that future delivery rates will depend largely on the consistency of engine shipments.

BENGALURU / LYNN (Massachusetts), — April 2, 2026 : GE Aerospace has implemented a series of structural and operational measures to accelerate the production and delivery of F404-IN20 engines to Hindustan Aeronautics Limited (HAL), in support of India’s Light Combat Aircraft (LCA) Tejas Mk1A programme. The company has established an additional dedicated production line for the F404-IN20 variant, introduced higher levels of automation in engine testing processes, and appointed a new management team to oversee production and delivery timelines. These steps form part of a coordinated ramp-up plan agreed between GE Aerospace and HAL to address supply chain delays and stabilise engine availability.   Delivery Schedule and Production Targets Under the revised roadmap, HAL is expected to receive 20 engines in the second half of the financial year 2026–27. HAL Chairman and Managing Director D.K. Sunil confirmed that deliveries are projected to increase to 24 engines during FY 2026–27, with further scaling to 30 engines annually from FY 2027–28 onward. As of early April 2026, GE Aerospace has delivered six engines under the original 2021 contract for 99 F404-IN20 units. Deliveries under this contract began in March 2025 after the production line was restarted. The line had previously been shut down in 2016 following completion of an earlier order of 65 engines. Initial delays in delivery were attributed to a combination of geopolitical tensions, pandemic-related supply chain disruptions, and the technical challenges associated with restarting a dormant production line.   Follow-on Orders and Programme Expansion In November 2025, HAL placed a follow-on order for 113 additional F404-IN20 engines, including spares and modules. Deliveries under this contract are scheduled to begin in 2027 and continue through 2032. The order supports the production of 97 additional Tejas Mk1A aircraft approved by India’s Ministry of Defence in September 2025. To support increased production requirements, GE Aerospace has also invested $14 million in its Pune facility in India. The investment focuses on expanding component manufacturing capacity, incorporating advanced manufacturing technologies, and increasing automation for specific engine parts.   Global Production Outlook and Platform Integration The F404 engine family, previously considered a mature or legacy platform, has seen its production lifecycle extended by nearly two decades due to renewed demand from multiple aerospace programmes. Current production timelines for new-build F404 engines are aligned with major platform requirements: HAL Tejas Mk1A (India): production expected until approximately 2032 Boeing T-7A Red Hawk (United States): production expected until approximately 2034 TAI Hürjet (Turkey): production expected to continue through 2030 and beyond The Boeing T-7A Red Hawk programme includes plans for more than 350 aircraft for the U.S. Air Force, with initial production deliveries beginning in late 2025 and initial operational capability targeted for 2027. Turkey’s Hürjet programme has entered mass production, supported by a manufacturing line capable of producing two aircraft per month. A memorandum of understanding signed in July 2025 between Turkish Aerospace Industries (TAI), GE Aerospace, and Turkish Engine Industries (TEI) provides for local assembly, inspection, testing, and maintenance of F404 engines within Turkey. Additional agreements, including the supply of F404 engine kits to Hanwha Aerospace in South Korea for integration into the FA-50/TA-50 aircraft family—also operated by the Polish Air Force—are contributing to sustained global demand.   Technical Characteristics and Long-Term Support The F404-IN20 is the highest-thrust variant within the F404 engine family, capable of delivering up to 85 kN of thrust. It incorporates Full Authority Digital Engine Control (FADEC) and advanced single-crystal turbine blade technology designed for modern combat aircraft requirements. Although the final new-build F404 engines are projected to be produced by the mid-2030s, GE Aerospace plans to continue manufacturing spare parts and critical components until 2050 or later. This extended support framework is intended to maintain operational readiness for global fleets operating F404-powered aircraft, including those in the United States, India, South Korea, and Poland.   Industrial Coordination and Programme Alignment The production ramp-up is aligned with HAL’s aircraft manufacturing expansion. HAL inaugurated a third Tejas Mk1A production line at its Nashik facility in October 2025 to meet increased aircraft output targets. GE Aerospace’s additional production line, combined with enhanced automation at its primary facility in Lynn, Massachusetts, and expanded manufacturing capabilities in Pune, is aimed at ensuring consistent engine supply. The company continues to coordinate closely with HAL on supply chain stabilisation measures to support the overall Tejas Mk1A production schedule.

New Delhi, — April 1, 2026 : According to report American aerospace manufacturer GE Aerospace has handed over the sixth F404-IN20 engine to Hindustan Aeronautics Limited (HAL) under a 2021 contract to power India’s indigenous Tejas Mk1A fighter jets. The latest delivery, confirmed at the close of the financial year 2025–26 on March 31, remains below revised targets and underscores ongoing supply chain and production constraints affecting the programme. HAL had expected 11 engines during the fiscal year; however, only six were delivered. According to HAL sources, the sixth engine has not yet physically arrived in India, with the handover completed at GE’s facilities in the United States. A spokesperson for GE Aerospace confirmed the development, stating that the company has delivered the sixth engine against the 2021 order and continues to coordinate closely with HAL to maintain visibility on production schedules.   Contract Scope and Delivery Timeline The original contract, signed in February 2021 and valued at approximately $716 million, covers the supply of 99 F404-IN20 engines along with logistics support, technical assistance, and associated equipment. These engines are intended for 83 Tejas Mk1A aircraft ordered by the Indian Air Force (IAF) on February 3, 2021. The first engine under this agreement was delivered in March 2025, followed by the fifth engine in December 2025. The sixth engine was handed over in March 2026. Earlier delays in the programme were attributed to the restart of the F404 production line, which had remained inactive for approximately five years after completion of earlier Tejas Mk1 orders. Despite these deliveries, engine availability has remained the primary constraint affecting the production timeline. Defence sources indicate that the engine supply issue has been the central bottleneck, with other challenges considered secondary.   Discrepancies in Delay Attribution Sources within the defence establishment stated that GE Aerospace attributed recent delays to the ongoing conflict involving the United States, Israel, and Iran, which began on February 28, 2026. However, a review of the delivery timeline indicates that no engines were supplied between December 2025 and late February 2026—a gap of more than two months prior to the outbreak of the conflict. This sequence suggests that supply chain disruptions predated the conflict, raising questions about the extent to which recent geopolitical developments have contributed to the slowdown.   Tejas Mk1A Programme Delays and Revised Timeline The Tejas Mk1A fighter, developed by the Aeronautical Development Agency (ADA) and manufactured by HAL, was originally scheduled for delivery to the Indian Air Force in March 2024. Multiple revised timelines have since been missed. Current projections indicate that the first batch of aircraft will be inducted no earlier than June or July 2026, representing a delay of more than two years from the initial schedule. To facilitate early deliveries in the current fiscal year, the Indian Air Force and the Ministry of Defence (MoD) agreed in February 2026 to grant HAL limited exemptions from certain contractual requirements. Under this arrangement, the Indian Air Force will accept the aircraft once three essential conditions are fulfilled: Completion of missile-firing tests Integration of the radar system with the electronic warfare suite Validation of the full weapons package Defence sources confirmed that missile-firing trials have been completed, and the certification process for the remaining systems is underway. These parameters have been identified as mandatory for acceptance under the revised framework.   Certification Status and Acceptance Process According to programme officials, major capabilities associated with the Tejas Mk1A are currently progressing through the certification pipeline, with completion expected by the end of April 2026. Following certification, the Indian Air Force is expected to begin its acceptance trials. This process is anticipated to take several weeks before the aircraft are formally inducted into service. HAL has maintained that a significant portion of the pending work falls under the purview of the Aeronautical Development Agency and relates to certification rather than manufacturing delays at HAL’s end.   Follow-On Orders and Future Production Plans In November 2025, HAL signed an additional contract with GE Aerospace for 113 more F404-IN20 engines to support an expanded Tejas Mk1A programme, which now includes 97 aircraft. Deliveries under this follow-on agreement are scheduled to begin in 2027 and continue through 2032. GE Aerospace has outlined plans to supply 20 engines in financial year 2026–27, with production expected to scale up to 30 engines annually from 2027–28 onward.

NEW DELHI, March 31, 2026 — The Ministry of Defence (MoD) has signed a capital acquisition contract worth ₹1,950 crore with Bharat Electronics Limited (BEL) for the procurement of two advanced Mountain Radar systems for the Indian Air Force (IAF). The agreement, finalised in New Delhi on the last day of the financial year 2025–26, covers the manufacturing, supply, installation, and commissioning of the radar systems, along with associated equipment, logistics support, and forward deployment infrastructure. The procurement has been executed under the Buy (Indian–Indigenously Designed, Developed and Manufactured) [Indian-IDDM] category, in line with the government’s Aatmanirbhar Bharat and Make in India initiatives. The project follows the Acceptance of Necessity (AoN) granted by the Defence Acquisition Council in August 2025 for the induction of Mountain Radars into the IAF.   Strategic Deployment in High-Altitude Regions The two radar systems will be deployed in Gulmarg (Jammu and Kashmir) and Pfütsero (Nagaland), targeting critical gaps in air surveillance along India’s northern and northeastern borders. These locations are characterized by complex mountainous terrain, including deep valleys, steep ridgelines, and harsh weather conditions that limit the effectiveness of conventional radar systems. The Mountain Radars are specifically designed to operate in such environments, ensuring reliable surveillance coverage and enhancing early warning capabilities in strategically sensitive sectors.   Advanced Capabilities for Air Surveillance The Mountain Radar is a fixed, medium-power 4D surveillance system based on a modified version of the Arudhra radar, adapted for high-altitude operations. It incorporates Active Aperture Phased Array (AESA) technology and operates in both rotation and staring modes. In rotation mode, the radar provides 360-degree azimuth coverage at speeds of 7.5 or 15 revolutions per minute, with an elevation coverage of 30 degrees. In staring mode, it focuses on a fixed azimuth sector of ±60 degrees, maintaining the same elevation coverage. The system has an instrumented range of 400 km and can detect targets with a radar cross-section of 2 square metres at distances up to 300 km. It offers altitude coverage ranging from 100 metres to 30 km, enabling detection and tracking across a wide operational envelope. Designed to address radar shadow zones, the system enhances detection of low-flying aerial threats that may otherwise evade conventional radar coverage. It is capable of tracking multiple targets simultaneously, including fighter aircraft, helicopters, unmanned aerial vehicles (UAVs), drones, cruise missiles, and ballistic missiles, while determining parameters such as range, azimuth, altitude, and velocity vectors. The radar uses S-band solid-state transceiver modules and supports track-while-scan functionality, allowing continuous monitoring of multiple airborne objects.   Integration into IAF’s Network-Centric Operations The Mountain Radar systems will function as critical nodes within the IAF’s integrated air defence network, bridging coverage gaps between low-level and long-range surveillance systems. This integration is expected to improve situational awareness, reduce response times, and strengthen command and control capabilities. The systems are engineered to maintain operational reliability in thin air conditions, rugged terrain, and variable weather, ensuring sustained performance in high-altitude deployments.   Indigenous Development and Industrial Participation The radar systems have been indigenously designed and developed by the Electronics and Radar Development Establishment (LRDE), a Bengaluru-based laboratory under the Defence Research and Development Organisation (DRDO). BEL will serve as the prime contractor, responsible for manufacturing, system integration, supply, installation, and lifecycle logistics support. The project also involves participation from a network of domestic suppliers, including Micro, Small, and Medium Enterprises (MSMEs), contributing to component manufacturing and raw material supply.   Strengthening Domestic Defence Capability According to defence ministry officials, the induction of these Mountain Radars will enhance India’s air defence architecture, particularly in terrain where surveillance limitations have persisted. The programme is also expected to contribute to the development of domestic technological capabilities and reduce dependence on foreign-origin military systems. The contract represents a continuation of India’s efforts to expand indigenous defence production while reinforcing operational preparedness in geographically challenging regions.
