Azért ne SHORAD-ozzuk le a NASAMS-ot.
Csapásmérők 10km felett harci helyzetben ritkán repkednek (B2-t kivéve).

NASAMS II (ItO 12): In 2004 new project began for both medium- and long range SAM acquisition. ... In final round in 2009, competition narrowed down between SAMP/T (with Aster missiles) and NASAMS II (which uses AMRAAMs). Key requirement was ability to cover both capital region, and 'one military target' simultaneously. SAMP/T was more in the class of Patriot or S-300. It had long range, but was somewhat cumbersome and vulnerable. NASAMS was much more resilient, cheaper and networked, so it won the contest. Synergy advantage for using same missile as Air Force was also mentioned (though this is IMO rather dubious advantage). NASAMS offered 'more bang for a buck': Chief-of-Defence commented that "Instead of a Cadillac, we bought four Volvos". Total cost of the contract was 346 million Euros.
NASAMS II is somewhat different beast compared to earlier variant which lost out to Buk M1 in mid-90s. Radar is much improved AN/MPQ-64 Sentinel, with detection range of 75 kilometres. This is not too long for missile of this class (and probably made worse by low mounting of the radar) but adequate given it's cheaper cost (which means more radars). In addition the system has MPS 600 electro-optical sensor, which has FLIR, TV camera and laser range finder; under good conditions it can detect targets from up to 40km range. Several different communication links are used, including Link 11B and Link 16. As AMRAAM uses it's own radar for terminal guidance, the system does not have dedicated fire control radar; target information can be fed to missile from either surveilance radar, IR sensor or even some outside source. Thus the system has 'fire and forget' capability, which Buk doesn't have. All vehicles are wheeled; terrain capability is thus much worse than with its predecessor, but on the plus side, vehicles are cheaper to maintain.
Biggest downside is that missile's range is meagre 25km and maximum ceiling is just 10km: this is insufficient for several current and prospective threats, so the system would need a true long-range missile alongside to cover this shortcoming, but there doesn't appear to be any money available for such system. Potentially, new missiles could be fitted to the system in the future to partly cover these shortcomings.
