The NSM can be fired from a range of platforms against a variety of targets. The passive homing missile travels in sea-skimming mode and can make advanced terminal manoeuvres in the terminal phase, to survive enemy air defences.
The missile, using GPS-aided mid-course guidance with a dual-band imaging infrared (IIR) seeker, detects and discriminates the targets. Autonomous target recognition (ATR) of the seeker ensures accurate detection and striking of sea or land based targets. A programmable fuse is used to detonate the missile’s warhead.
Propulsion of Kongsberg Defence Systems’ NSM
The NSM is launched into the air by a solid rocket booster which is jettisoned upon ignition. The Microturbo TRI-40 turbojet engine propels the missile towards its target with high subsonic speed.
