Satellite Helps US Ship Shoot Down Missile.

The missile cruiser USS Lake Erie was able to shoot down a medium-range ballistic missile in a test using tracking information sent from a satellite, before the ship's powerful radar detected the missile. This was the first time remote data was used for an intercept and the 22nd success out of 30 tries for the  SM-3 Ballistic Missile Defense program. Twenty-six US navy cruisers and destroyers are equipped for BMD with more on the way.
