BENGALURU, — April 10, 2026 : Hindustan Aeronautics Limited (HAL) has delivered four Advanced Light Helicopter (ALH) Mk III Maritime Role (MR) helicopters to the Indian Coast Guard (ICG) during a formal handover ceremony held in Bengaluru.
The helicopters were officially received by Rajesh Makwana, Deputy Inspector General and Coast Guard Commander (Western Seaboard), from PB Rangarao, Chief Executive Officer of HAL’s Helicopter Complex. The transfer of operational documentation was carried out by the Office of the Regional Director, Aeronautical Quality Assurance (ORDAQA), along with HAL’s Helicopter Division.
Following the completion of documentation formalities, the newly delivered helicopters have been assigned to Coast Guard squadrons based in Kochi and Porbandar, where they will support maritime operations along the western seaboard.
Procurement and Delivery Timeline
The latest delivery forms part of a broader procurement framework between the Ministry of Defence and HAL aimed at strengthening the Coast Guard’s rotary-wing fleet.
HAL had earlier completed the delivery of 16 ALH Mk III (MR) helicopters to the Indian Coast Guard by 2022. A subsequent contract for nine additional helicopters was signed in March 2024, under which the four helicopters handed over on April 10, 2026, represent a partial fulfillment.
More recently, in March 2026, the Ministry of Defence signed another contract valued at ₹2,901 crore for six additional ALH Mk III (MR) helicopters. This contract includes not only the airframes but also operational role equipment, an engineering support package, and performance-based logistics support. The procurement falls under the Buy (Indian-IDDM) category, reflecting a significant level of indigenous design and manufacturing.
Design and Technical Enhancements
The ALH Mk III represents an upgraded configuration of the earlier Mk II variant, incorporating 19 major improvements. The helicopter is powered by twin Shakti-1H1 turboshaft engines, also known as Safran Ardiden 1H1, delivering higher power output compared to the Turbomeca TM 333 engines used in the Mk II. This enhancement provides improved performance margins, especially in maritime and high-altitude environments.
The platform features a fully digital glass cockpit equipped with HAL’s Integrated Architecture Display System (IADS), replacing conventional instrumentation. It also incorporates an upgraded automatic flight control system and open-architecture avionics, enabling enhanced situational awareness and improved flight handling.
Additional refinements include improved vibration control, reduced empty weight through the use of lightweight avionics and sensors, and increased payload capacity. The helicopter’s maximum all-up weight has been increased to approximately 5.5 to 5.75 tonnes, contributing to better operational flexibility.
Specifications of ALH Mk III (Maritime Role)
The ALH Mk III (MR) is a twin-engine, multi-role helicopter designed for both shore-based and ship-borne operations.
It is operated by a crew of two, consisting of a pilot and co-pilot, and can accommodate between 12 and 14 passengers or troops. The helicopter has a maximum speed ranging between 250 and 291 km/h, with a cruise speed of approximately 250 km/h.
It offers an operational range of about 630 to 700 kilometers and an endurance of up to 4 hours and 20 minutes. The service ceiling is between 6,000 and 6,500 meters. The platform is capable of carrying up to 1,500 kilograms as a slung load, along with higher payload capacity for deck-based operations.
Dimensionally, the helicopter has a main rotor diameter of 13.2 meters, an overall length of approximately 15.87 meters with rotors turning, and a height of around 4.98 meters.
Maritime Role Equipment and Mission Systems
The Maritime Role variant is equipped with a comprehensive suite of mission systems tailored for coastal and offshore operations. These include a nose-mounted 270-degree surveillance radar capable of detecting ships and boats at ranges of up to 120 nautical miles.
The helicopter is also fitted with a multi-spectral electro-optical/infrared (EO/IR) pod for target identification and tracking, along with an automatic identification system (AIS) for vessel monitoring. Additional equipment includes a high-intensity searchlight, loudhailer, and a 360-degree search-and-rescue homer.
For rescue operations, the platform is equipped with an electrically operated winch with a 250 kg lifting capacity and a rescue basket. Safety systems include a traffic alert and collision avoidance system (TCAS). The helicopter can also be fitted with a 12.7 mm cabin-mounted machine gun for mission-specific requirements.
A removable Medical Intensive Care Unit (MICU) is integrated for casualty evacuation missions, enabling critical care during transit. The helicopter also supports pressure refueling and features folding main rotor blades and tail boom, allowing efficient operation from ships.
Operational Roles and Capability Expansion
The induction of these helicopters enhances the Indian Coast Guard’s operational capabilities across multiple mission profiles. These include maritime surveillance, interdiction operations, search and rescue (SAR), pollution response, medical evacuation, and logistics support.
The helicopters are also capable of supporting island protection missions and can operate seamlessly from both shore bases and vessels at sea, providing flexibility in deployment.
With over 57 percent indigenous content, the ALH Mk III program aligns with India’s domestic defense manufacturing objectives. The continued induction of these helicopters is expected to strengthen maritime security, offshore patrol capabilities, and disaster response readiness along India’s coastline.
