About Next-Generation Missile Vessels (NGMVs):

• The NGMVs are envisaged as high-speed vessels equipped with an array of weapons and sensors, being built for the Indian Navy.
• Six NGMVs are being built by government-run Cochin Shipyard Limited (CSL) at a cost of Rs 9,805 crore.
• Delivery of the vessels is scheduled to commence from March 2027.
• The primary role of the ships would be to provide offensive capability against enemy warships, merchantmen, and land targets.
• The vessels are intended for maritime strike and anti-surface warfare operations and will also provide the Navy with sea-denial capability, particularly around strategically important maritime choke points.
• In defensive operations, the ships are expected to support local naval defence and the protection of offshore development areas.
• Features:
  • The core of the NGMV propulsion system is the LM2500, a marine gas turbine, manufactured by the American engine manufacturer General Electric. LM2500 is engineered to unleash superior power while meeting stealth requirements.
  • Each vessel will have a complement of around 80 personnel and a maximum speed of approximately 33 knots (61 kmph).
  • These corvettes can remain at sea for 10 consecutive days and extend their stay by refueling from tankers.
  • They will be equipped with surface-to-surface missile systems, anti-missile defence systems, air-surveillance radars, and fire-control radars.
  • The NGMVs’ primary weapon will be the BrahMos supersonic cruise missile, capable of striking targets at long ranges.
  • The vessels will also be equipped with advanced integrated platform management systems, propulsion and auxiliary machinery, power generation and distribution systems and damage-control machinery.
