NASA Armstrong Fact Sheet: B-52H Air-Launch and Research Testbed
February 28, 2014
 

NASA obtained a B-52H heavy bomber from the U.S. Air Force in 2001, intending to use the aircraft as an air-launch and testbed aircraft to support NASA, Air Force, and industry flight research and advanced technology demonstration efforts at NASA's Dryden Flight Research Center, Edwards, CA.

NASA Dryden's B-52H in flight. NASA Dryden's fabrication branch built a new, in-house designed pylon for the B-52H to carry aerospace test vehicles aloft. The new pylon was designed with the flexibility to adapt to the variety of aerospace vehicle shapes and sizes, and could carry a load weighing up to 25,000 lb.

The B-52H, USAF serial number 61-0025, arrived at NASA Dryden on July 30, 2001 from the USAF's 23rd Bomb Squadron, 5th Bombardment Wing, located at Minot AFB, ND. Initially placed on loan, the aircraft was later transferred from the USAF to NASA.

NASA was performing design, analysis, and testing leading up to a Critical Design Review at the end of 2007. As part of the preliminary studies, several "captive-carry" flights were planned to be flown by the F-15 with an inactive missile with no propellant carried on the aircraft's centerline pylon to determine the performance of the aircraft when carrying the missile. The project has not been funded to conduct actual launches to obtain hypersonic flight test data, and a decision on funding such research was not expected before 2008.

Following de-militarization and programmed depot maintenance at Tinker Air Force Base, OK, a flight research instrumentation package was then installed on the aircraft, as well as other modifications to support its launch platform role.

The B-52H was intended to replace Dryden's famous B-52B "008", which was retired on Dec. 17, 2004. However, with no research projects requiring its capabilities on the horizon under NASA's restructured aeronautics research programs, the decision was made to return the aircraft to the Air Force, which intended to use it as a training aid for B-52 ground technicians. Physical transfer of the aircraft was expected to occur in mid-2007.
