Indian Coast Guard Commissions Indigenous Fast Patrol Vessel ICGS Ajit at Goa Shipyard

On October 9, 2026, the Indian Coast Guard officially commissioned ICGS Ajit, a state-of-the-art indigenous Fast Patrol Vessel (FPV), during an official ceremony at Goa Shipyard Limited in Vasco da Gama, Goa. Presided over by Dr. Sirish Choudhary, Principal Integrated Financial Advisor to the Indian Coast Guard, the commissioning marks the operational induction of the seventh vessel in the eight-ship Adamya-class series. The vessel was formally handed over to the maritime service by Goa Shipyard Limited on August 25, 2026, following extensive harbor and sea trials. Constructed under a Ministry of Defence contract valued at approximately ₹473 crore awarded in March 2022, the Adamya-class project underscores the expanding capability of Indian shipyards to conceptualize, engineer, and deliver naval platforms. ICGS Ajit incorporates more than 65 percent indigenous components by value, reinforcing the national mandate for self-reliance in defense manufacturing and critical maritime infrastructure.

Naval Architecture and Hull Specifications

Designed completely in-house by Goa Shipyard Limited, ICGS Ajit is tailored specifically for rapid response, coastal surveillance, and patrol duties in shallow waters and nearshore maritime domains. The platform measures 51.43 metres in length and 8 metres in beam, with a design draught of under 2.5 metres and a displacement of approximately 330 tonnes. This compact hydrodynamic footprint enables the vessel to navigate restrictive coastal channels, river mouths, and island archipelagos that are inaccessible to larger ocean-going frigates or corvettes.

The internal layout of ICGS Ajit is optimized to accommodate a complement of 41 personnel, comprising 6 officers and 35 sailors. Its operational charter encompasses a broad spectrum of defense and maritime law enforcement missions, including:

• Exclusive Economic Zone Surveillance: Monitoring maritime boundary lines and safeguarding offshore natural assets.
• Coastal Security and Patrols: Maintaining a continuous presence along critical maritime corridors to deter illicit activities.
• Fisheries Protection: Enforcing maritime regulations and safeguarding domestic fishing fleets from foreign encroachment.
• Anti-Smuggling and Anti-Piracy Operations: Conducting rapid interception of non-compliant craft and suspicious sea vessels.
• Search and Rescue and Marine Pollution Control: Executing emergency response missions and containing hazardous spills in coastal ecosystems.

The Indian Coast Guard has designated Okha, situated along the northern coastline of Gujarat, as the permanent operational base for ICGS Ajit. From this strategic position, the vessel will bolster maritime security across the northern Arabian Sea, safeguarding critical international shipping lanes, offshore oil terminals, and sensitive coastal waters.

Advanced Marine Propulsion and Controllable Pitch Propeller Systems

A primary technical highlight of ICGS Ajit lies in its advanced propulsion architecture. The vessel is powered by two marine diesel engines, each generating 3,000 kW (4,000 hp) of continuous power, yielding a total propulsive output of 6,000 kW. These prime movers are paired with indigenously developed gearboxes and twin Controllable Pitch Propellers (CPP). The integration of controllable pitch propeller technology represents a significant milestone, as ICGS Ajit and its sister Adamya-class vessels are the first in this fast patrol vessel category within the Indian Coast Guard to feature this capability.

In traditional fixed-pitch propeller configurations, vessel speed and direction changes require adjustments to engine rotational speed or gearbox gear engagement. In contrast, a controllable pitch propeller system allows onboard hydromechanical actuators to dynamically alter the blade angle of attack while maintaining optimal engine rotation speeds. This mechanical flexibility delivers distinct operational advantages:

• Enhanced Hydrodynamic Efficiency: The propeller blade pitch can be calibrated continuously to match varying sea conditions, payload displacements, and towing loads, ensuring peak fuel efficiency across different operational regimes.
• Rapid Acceleration and Deceleration: Adjusting blade pitch provides immediate propulsive response, allowing the vessel to accelerate past 27 knots (with a top speed of up to 28 knots) or stop rapidly during high-speed interdictions.
• Precision Maneuvering at Low Speeds: Fine control over thrust magnitude and direction simplifies station-keeping, docking, and search and rescue maneuvers in turbulent coastal waters without stalling the main engines.

At an economical cruising speed of 14 knots, ICGS Ajit achieves an operational endurance of 1,500 nautical miles with a 25 percent fuel reserve. This extended range allows the craft to sustain multi-day patrols across expansive offshore zones without frequent refueling stops.

Shipboard Automation, Integrated Systems, and Combat Capabilities

To maximize operational effectiveness while keeping crew requirements lean, ICGS Ajit features an extensive suite of automated monitoring and platform management technology. At the core of the ship's machinery room is an Integrated Machinery Control System (IMCS), which continuously monitors critical engine parameters, hydraulic fluid pressures, fuel flow rates, and electrical generation systems. This automation is complemented by an Integrated Bridge System (IBS), an Integrated Platform Management System (IPMS), and an Automated Power Management System, allowing deck officers to manage platform navigation, damage control, and power distribution from centralized control stations.

The combat layout of ICGS Ajit is structured to provide proportional force and defensive protection during maritime policing and security tasks. The primary armament consists of a forward-mounted CRN 91 30mm naval gun, capable of delivering rapid, accurate suppressive fire against surface targets. Supplementary fire support is provided by two 12.7mm stabilized remote-controlled machine guns. These weapon platforms are integrated with stabilized electro-optical tracking sensors and modern fire control systems, enabling target engagement under all-weather conditions, day or night.

Strategic Importance for Domestic Shipbuilding and Industrial Supply Chains

The commissioning of ICGS Ajit marks the seventh successful induction in the eight-ship FPV contract awarded to Goa Shipyard Limited. With earlier sister ships such as ICGS Adamya, ICGS Akshar, and ICGS Akshay already in active operational service, only the final vessel in the series—ICGS Aparajit—remains to complete the build program. The progression of this construction project highlights the maturing capabilities of domestic public sector shipyards in managing series production of specialized military craft.

Achieving over 65 percent domestic content in ICGS Ajit required deep integration with India's domestic engineering supply chain. Sub-contractors across the country supplied high-strength marine steel, specialized gearboxes, high-pressure hydraulic pitch control units, electrical distribution panels, and auxiliary cooling networks. By shifting away from foreign component reliance for complex propulsion elements like controllable pitch gearboxes, the program strengthens domestic industrial resilience and reduces lifecycle maintenance overhead for the Indian Coast Guard.

Test Infrastructure Imperatives for Next-Generation Maritime Platforms

The successful operation of high-performance patrol vessels depends heavily on the structural reliability and hydraulic precision of their onboard sub-systems. Complex machinery—ranging from controllable pitch propeller hydraulic actuators and high-pressure pneumatic engine-starting systems to automated steering gear, fire control stabilization, and valve control manifold networks—must endure severe hydrodynamic shocks, extreme pressure fluctuations, and corrosive marine environments throughout their service life.

Validating these mission-critical components prior to integration requires sophisticated ground-based testing hardware. Custom hydraulic test benches, high-pressure gas test rigs, automated actuator test systems, and specialized pressure calibration facilities engineered by domestic industry partners such as Neometrix Defence Limited provide the foundational test infrastructure necessary to evaluate hydraulic seal integrity, dynamic pressure response, and automated system performance, ensuring that indigenous maritime platforms operate with uncompromising reliability at sea.
