What are Next Generation Missile Vessels (NGMV)?

About Next Generation Missile Vessels (NGMV):

• The NGMVs would be heavily armed war vessels incorporating stealth, high speed, and offensive capability 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.
• The delivery of ships 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.
• These ships will be capable of conducting Maritime Strike Operations and Anti Surface Warfare Operations and would be a potent instrument of sea denial for enemy ships, especially at choke points.
• In a defensive role, these ships would be employed for Local Naval Defence operations and seaward defence of Offshore Development Area.
• 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.
  • With a top speed of 35 knots (64 kmph), these vessels carry an array of anti-surface weapons.
  • The CSL will equip the vessels with loitering munitions, unmanned vehicles, and other guided weapons to add to its firepower.
  • The NGMVs' primary weapon is anticipated to be the BrahMos supersonic cruise missile, capable of striking targets at long ranges.
