A military killer drone, er ... missile defense took one step closer to reality. Here's a video clip of a "multiple kill vehicle" completing its hover test:
Objectives of the test included having the MKV-L hover under its own power and prove its capability to recognize and track a surrogate target in a flight environment. During the test, the MKV-L's propulsion system demonstrated maneuverability while tracking a target. The MKV-L transmitted video and flight telemetry to the ground.
