United Launch Alliance and SpaceX recently won contracts worth $739 million to send six missions into orbit for the U.S. military, and the Air Force has announced a new title for its flagship launcher program, dropping “expendable” from the name in a new era of reusable rockets.

The most powerful configuration of United Launch Alliance’s Atlas 5 rocket blasted off April 14 from Cape Canaveral, hauling multiple U.S. Air Force satellites to a perch high above the equator after piercing a clear evening sky over Florida’s Space Coast with 2.6 million pounds of thrust.

The 32-story-tall mobile service tower at the Delta 4’s launch pad at Vandenberg Air Force Base in California was retracted away from the rocket Thursday in advance of a planned liftoff with a top secret National Reconnaissance Office payload.
