>>141  SPY-1はフェイズド・アレイ・レーダーなんだけど、なんでソフトの切り替えが必要な訳?グロセキュには↓のようにあるんだけど   
 A conventional, mechanically-rotating radar "sees" a target when the radar beam strikes that target once during each 360 degree rotation of the antenna. 
 A separate tracking radar is then required to engage each target.  
 By contrast, the computer-controlled AN/SPY-1A Phased Array Radar of the AEGIS system brings these functions together within one system. 
 The unique SPY-1 multi-function phased array radar system replaces numerous conventional independent sensors and is designed for the most challenging environments and missions, 
 including long-range volume search, fire control-quality tracking and ballistic missile defense.  
 SPY-1's S-band frequency range permits optimum performance in all-weather operations(改行) 
 and the ability to perform all major radar functions while simultaneously providing proven S-band mid-course guidance for semi-active missiles, 
 such as the Evolved Sea Sparrow Missile, SM-2 and SM-3.

 同じページに弱点(WEAKNESSESなので弱みとするべき?)も載っているが、弾道ミサイルの追尾中は艦隊防空ができないなんて書いてないぞ 
 MD対応のためにソフトの改修が必要なのは知っているがそのことじゃないよな?
