미사일 방어국: 두 판 사이의 차이

- in December 2003, MDA awarded a contract to [[Northrop Grumman]] for developing and testing - perhaps later also to be applied for mid-course defense. It has to be launched from a location not too far from the launch site of the target missile (and is therefore less suitable against large countries), it has to be fired very soon after launch of the target, and it has to be very fast itself (6 km/s).
