Patches made for OXCART crew members. CYGNUS was the name given the A-12 in testing. The 1129th SAS was the unit designation of the A-12 team assigned to Kadena Air Base in Okinawa.

“The A-12 ‘practically spawned its own industrial base’ and the 2,400 or so machinists, mechanics, and fabricators could do their own milling and forging.” The sign at the top, “Stamp out F.O.D.” was an exhortation to “Stamp Out Foreign-object Damage,” a problem of engine failure sometimes caused by small objects inadvertently dropped and left in nacelles during fabrication.

The J58 jet engine during a static test. A modified version of an engine designed for another program four years earlier, the jet generated as much power as the turbines of the ocean liner the Queen Mary.

In this photo, one of the first of the A-12 released by CIA, the adjustable inlet cones in front of the en-gines are clearly visible. Called “spikes,” the devices regulated the incoming air flow to maximize thrust and prevent interruptions in fuel combustion at high speeds.

Hauled disassembled and in boxes to its Nevada test site, the A-12 posed a significant traffic hazard. Once, an oncoming bus grazed a crate.

Throughout testing, flight procedures evolved; in effect, pilots were testing and training simultane-ously. Here, the only A-12 trainer built—the “Titanium Goose”—is about to refuel, a process that took the A-12 close to stall speed when it was filled up.
