The 15th space shuttle mission (51-C) is the first all-military flight. The Discovery crew of Navy Capt. Thomas K. Mattingly (mission commander), Air Force Lt. Col. Loren J. Shriver (pilot), and Air Force mission specialists Lt. Col. Ellison S. Onizuka and Maj. Gary E. Payton, along with Marine Lt. Col. James F. Buchli, deploy a classified payload, believed to be a signals intelligence satellite.
The Air Force hasn't asked for more than 100 B-21s because it won't get there for at least a decade and something better may be developed first, Chief of Staff Gen. David Allvin told the Senate Armed Services Committee.
