NASAMS (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).[1]


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 state-of-the-art 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 RNoAF 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 ARCS maintained connection to higher echelons and ensured protection of friendly aircraft while preventing over- and underkill for all subordinate weapon systems. NASAMS capabilities[2] are enhanced by the system's networked and distributed nature.

The RNoAF together with KDA has conducted a mid-life update of the NASAMS, called NASAMS 2, and the upgraded version was first handed over to RNoAF in mid-2006. The major difference the two versions will be the use of Link 16 on NASAMS 2 as well as a better ground radar. Full operational capability (FOC) was expected for 2007.


The system integrates US-built AN/MPQ-64 F1 Sentinel air defense radar and AIM-120 AMRAAM missiles with an indigenously developed Battle management C4I system called FDC, short for Fire Distribution Center. The FDC connected to a MPQ-64 radar forms an "Acquisition Radar and Control System" (ARCS). The missile has a horizontal range of up to 25 km.[3] Other sources cite a range of 'over 15 km'[4] but this depends on the missile version used.

AMRAAM missile range:
AIM-120A/B: 55–75 km
AIM-120C-5: >105 km
AIM-120D (C-8): >180 km[citation needed]

Note that ranges for AAMs are estimated for head-on encounters for fast moving aircraft at an altitude, and the range is significantly shorter when the same missiles are launched from stationary ground platforms. Further dimensioning for a stationary ground-launched-missile system is its maximum altitude reach, which by rule of thumb is one third of its maximum horizontal range.



On 22 February 2015, Raytheon announced the development of the Extended Range upgrade to the NASAMS AMRAAM missile offering (AMRAAM-ER). Development work began in 2014, and the missile is actually an Evolved Sea Sparrow Missile using AMRAAM guidance. The first flight test took place in August 2016.[5] Production is expected by 2019.[6] Engagement envelope is expanded with a 50 percent increase in maximum range and 70 percent increase in maximum altitude;[7] range will extend to about 40 km.[8]

Service history[edit]

The NASAMS has been exported to the United States, with the NASAMS 2 upgrade having been exported to Finland, the Netherlands, Spain, Oman, and Chile.[9][10] Chile is though not mentioned as an official user, as Kongsberg stated: "NASAMS is in operational use in Norway, Spain, USA, the Netherlands, Finland, and one undisclosed customer, and in production for Oman."[11]

Several NASAMS were used to guard air space over Washington, D.C. during the 2005 United States presidential inauguration, and are used to protect air space around the White House.[12][13][14]

On 26 October 2017, Lithuania announced that it would be purchasing the NASAMS system to improve its own air defense capabilities.[15]
