Pentagon Has Far-Reaching Defense Spacecraft in Works: "The Pentagon is working to develop a suborbital space capsule within the next five years that would be launched from the United States and could deliver conventional weapons anywhere in the world within two hours, defense officials said.

This year, the Falcon program will test a launcher for its Common Aero Vehicle (CAV), an unmanned maneuverable spacecraft that would travel at five times the speed of sound and could carry 1,000 pounds of munitions, intelligence sensors or other payloads. Among the system's strengths is that commanders could order a CAV -- an unpowered glide vehicle -- not to release its payload if they decided not to follow through with an attack."
