Key Highlights
- The Indian Coast Guard initiated construction of two Next‑Generation Offshore Patrol Vessels (Yard 16402 & 16403) on 17 March 2026 at YMPL, Ratnagiri.
- Each vessel measures 117 m, can travel up to 5,000 nm, and sprint at 23 knots, enabling prolonged offshore patrols.
- Designed for a crew of 11 officers and 110 sailors, they incorporate AI‑driven predictive‑maintenance suites.
- Built entirely by Mazagon Dock Shipbuilders Ltd. under the Buy‑Indian‑IDDM scheme, the ships support the Atmanirbhar Bharat defence agenda.
- Beyond surveillance, the OPVs will execute SAR, anti‑smuggling, and offshore‑asset protection missions.
Detailed Insights
The keel‑laying ceremony for Yard numbers 16402 and 16403 signified the commencement of a six‑ship programme intended to upgrade the Indian Coast Guard’s blue‑water reach. With a length of 117 metres, these hulls are engineered to sustain operations in a broad spectrum of sea states while maintaining a cruising range of roughly 5,000 nautical miles. Their propulsion package delivers a top speed of 23 knots, a metric that balances endurance with rapid response capability.
Human‑resource planning anticipates a complement of 11 commissioned officers and 110 enlisted personnel, providing sufficient manpower for multi‑dimensional tasks such as intelligence‑driven surveillance, coordinated search‑and‑rescue, and interdiction of illicit trafficking. A flagship feature is the integration of artificial‑intelligence‑based predictive maintenance, which continuously monitors critical subsystems to flag potential failures before they manifest, thereby enhancing operational availability.
Strategically, the vessels embody India’s push for self‑reliance in defence manufacturing. Mazagon Dock Shipbuilders Limited (MDL) is responsible for the indigenous design, development, and construction, fulfilling the Buy‑Indian‑IDDM (Indigenously Designed, Developed and Manufactured) mandate. The contract, signed on 20 December 2023, underscores a policy shift away from foreign procurement toward domestic capability cultivation.
Functionally, the OPVs are versatile platforms. Their sensor suite, communication array, and optional unmanned aerial vehicle (UAV) launch capability make them suitable for maritime domain awareness, while onboard boarding teams enable anti‑smuggling operations. The vessels also serve as forward bases for protecting offshore infrastructure such as oil platforms and undersea cables.
Key Concepts
- Predictive Maintenance: An AI‑enabled methodology that analyzes real‑time equipment data to forecast failures, allowing pre‑emptive repairs.
- Buy‑Indian‑IDDM: A defence acquisition policy that prioritises items that are designed, developed, and manufactured within India.
- Offshore Patrol Vessel (OPV): A medium‑sized warship optimized for extended patrol, surveillance, and low‑intensity maritime security tasks.
- Maritime Domain Awareness (MDA): The comprehensive understanding of any activity, event, or condition within the maritime environment that could impact security, safety, economy, or the environment.
