NASAMS (National/Norwegian Advanced Surface to Air Missile System) is a distributed and networked medium to long range air-defence system.
NASAMS was the first surface-based application for the AIM-120 AMRAAM (Advanced Medium Range Air-to-Air Missile).
The missile itself is named SLAMRAAM (Surfaced Launched AMRAAM).
The Norwegian company Kongsberg Defence & Aerospace teamed up with Raytheon and initiated the NASAMS programme as a cooperative effort for the Royal Norwegian Air Force.
The network-centric air defence system NASAMS was declared fully operational capable in 1998 but had an initial operational capability as early as in 1994/95.
Until the late 1990s the RNo AF ground-based air defence solution, also known as the Norwegian Solution (NORSOL), consisted of three different weapon systems; the 40mm Bofors L70 gun (controlled by the Oerlikon Contraves FCS2000 monopulse doppler tracking radar), the laser beam riding RBS 70 MANPADS system and the NASAMS.
All three systems were integrated through the ARCS via field wires and radio.
The RNo AF together with KDA conducted a mid-life update of NASAMS, called NASAMS 2, and the upgraded version was first handed over to RNo AF in mid-2006.
The major difference between the two versions is the use of Link 16 on NASAMS 2 as well as a better ground radar.
Full operational capability (FOC) was expected for 2007.
A complete NASAMS (2) battery consists of 12 missile launchers (LCHR) (each one carrying six AIM-120 AMRAAM missiles), eight radars (AN/MPQ-64 Sentinel F1 Improved Sentinel X band 3D radar), one fire control centre (CTOC), one electro-optical camera vehicle (MSP500) and one Tactical Control Cell (TCC) vehicle.
The upgrades consist of: The control system can detach itself from the sensors, in order to become less visible.
