NEW DELHI / PUNE : The Indian Navy has begun inducting its first indigenous autonomous weaponized Fast Interceptor Crafts (FICs), marking a significant expansion of India’s unmanned maritime warfare capabilities and placing the country among a small group of navies capable of deploying armed unmanned surface vehicle (USV) swarms.
The initial batch of two unmanned surface vehicles has been delivered by Pune-based Sagar Defence Engineering and dispatched for operational deployment under the Western Naval Command. The induction forms part of a larger order for 12 platforms, officials familiar with the programme said.
First Indigenous Weaponized USVs
This induction represents the first time the Indian Navy has fielded an indigenously designed and weaponized unmanned surface combat platform. Until now, the Navy’s unmanned surface capabilities were largely limited to imported systems, primarily employed for mine counter-measure (MCM) roles under restricted mission profiles.
The newly inducted platforms are configured as Fast Interceptor Crafts, intended for high-speed maritime security missions, coastal defence, and offensive interdiction tasks. Their entry into service reflects a doctrinal shift towards the use of unmanned systems in frontline combat and deterrence roles.
Programme and Procurement Framework
The vessels have been developed under the Innovations for Defence Excellence (iDEX) initiative and overseen by the Defence Innovation Organisation, which supports indigenous defence innovation, rapid prototyping, and competitive development. Defence officials said Sagar Defence secured the order after completing extensive trials demonstrating endurance, autonomy, and operational reliability.
A key milestone trial involved an autonomous long-distance transit of around 1,500 kilometres from Mumbai to Tuticorin, validating the platform’s navigation, propulsion, and systems integration over extended durations.
Design and Operational Capabilities
The autonomous interceptor crafts are approximately 17 metres in length and are engineered for sustained maritime operations. According to defence sources and manufacturer data, the vessels offer over 48 hours of continuous endurance and an operational range of about 400 nautical miles, enabling persistent surveillance and response missions along India’s western seaboard.
The crafts are capable of speeds exceeding 50 knots, allowing interception of fast-moving surface targets, including small boats and asymmetric maritime threats. Their performance supports roles in port security, offshore asset protection, and rapid reaction operations.
Armament and Modularity
In their primary configuration, the USVs are equipped with a 12.7 mm stabilized remote-controlled gun system, enabling precise engagement of surface threats while operating autonomously or under remote control. The platform incorporates a modular architecture, allowing future integration of short-range guided missiles, loitering munitions, or specialized surveillance payloads, depending on mission requirements.
Naval officials said the modular design allows rapid role reconfiguration without major structural changes, increasing operational flexibility.
Swarm Operations and Command Control
A defining capability of the Fast Interceptor Crafts is their ability to operate in coordinated swarm formations. Multiple USVs can be controlled from a single ground control station or from a mother ship, enabling synchronized manoeuvres, distributed target engagement, and wide-area coverage.
This concept allows the Navy to multiply force projection while reducing risk to human personnel.
Navigation and Electronic Warfare Resilience
The platforms are designed for operations in contested electromagnetic environments. In the event of GPS jamming or denial, the USVs can continue navigation using India’s indigenous NavIC, supported by advanced inertial navigation systems. This ensures mission continuity in electronic warfare conditions.
Manned–Unmanned Flexibility
Although primarily unmanned, the Fast Interceptor Crafts retain manned–unmanned teaming capability. The vessels can be reconfigured to carry up to 14 personnel, including special operations teams, for insertion, extraction, or boarding missions, expanding their operational utility.
Deployment and Future Role
The first two USVs are expected to be based along the western coast, contributing to the protection of critical sea lines of communication, ports, and offshore installations. The remaining platforms from the 12-unit order are scheduled for phased induction following further operational evaluation.
Defence officials said the programme reflects a broader effort to integrate autonomous systems into India’s naval force structure while strengthening domestic defence manufacturing. The induction of the Sagar Defence Fast Interceptor Crafts is expected to support future development of unmanned surface combat platforms in India.
