The inclusion of six more NASAMS, as well as more munitions for them to fire, is particularly significant. The U.S. government had previously announced plans to transfer two NASAMS to Ukraine. It remains unclear how the NASAMS heading to Ukraine will be configured. A number of different versions of the system exist now, made up of different combinations of launchers, radars, other sensors, and command and control nodes. For instance, certain variations of NASAMS incorporate missile launchers mounted on Humvees or other light vehicles. Tests have also been conducted of the M142 High Mobility Artillery Rocket System (HIMARS) vehicle, which Ukraine has now received at least 16 of, as a launch platform for the AIM-120 Advanced Medium Range Air-to-Air Missile (AMRAAM), which could be utilized with NASAMS. The Norwegian company Kongsberg Defence & Aerospace teamed up with Raytheon and initiated the NASAMS program as a cooperative effort for the Royal Norwegian Air Force. The state-of-the-art network-centric air defense system NASAMS was declared fully operational capable in 1998 but had an initial operational capability as early as in 1994/95. The RNoAF together with KDA is currently running a mid-life update of the NASAMS, called NASAMS II, and the upgraded version was first handed over to RNoAF in mid-2006. The major difference between the two versions will be the use of Link 16 on NASAMS II as well as a better ground radar. Full operational capability (FOC) was expected for 2007.

The system integrates US-built AN/TPQ-36A LASR (Low Altitude Surveillance RADAR) 3D radars and AIM-120 AMRAAM missiles with an indigenously developed BMC4I system called FDC, short for Fire Distribution Center. The FDC connected to a TPQ-36A radar forms an "Acquisition Radar and Control System" (ARCS). The missile has a range of up to 25 km. Other sources cite a range of 'over 15 km'. Note that ranges for AAMs are estimated for head-on encounters for fast moving aircraft at an altitude, and the ranges are significantly smaller when the same missiles are launched from stationary ground platforms.
