Third prototype. Made 138 flights (829.4 hours) as an offensive and defensive systems testbed before the B-1A program was cancelled in 1977. To Lowry AFB as as GB-1A ground trainer then preserved at the Wings Over the Rockies Aviation and Space Museum at the former Lowry AFB, Denver, CO from 1989.

The B-1A had a number of unique design features that did not make their way into the B-1B, including variable aspect engine intakes which moved to give the best performance at a variety of speeds, and an escape capsule that would eject the entire crew together in case of an emergency.This B-1A was the third aircraft built out of four. The Air Force assigned it to Lowry AFB in 1989 to serve as a ground trainer for munitions loading procedures. It is on loan from the National Museum of the US Air Force. (from the museum's website)
