The second A12 to be built for flight testing although for a time in 1962 it was suspended inverted on a pole at Area 51 for radar signature testing. 13 A12's were built for the CIA's "Oxcart" program before being superseded by the USAF's two seat SR71. The aircraft were mothballed in 1968 and "925" was moved in April 1977 to the MASDC at the Davis-Montham Air Force Base near Tuscon, AZ and finally to Intrepid in 1990.
