XGAM-71 Buck Duck

The XGAM-71 Buck Duck was a decoy missile that was developed by Convair in the late 1950s. It was intended to have the same radar signature as the Strategic Air Command's B-36 bomber, thereby allowing it to disrupt the enemy's air defenses and dilute their effort to shoot down an incoming bomber fleet.

Convair built the first prototype using their own funds, but received an official development contract from the United States Air Force on 16 August 1954. The project designation was MX-2224. When the Air Force decided to put the project into production, it received the designation GAM-71.

As initially envisioned by the Air Force, one B-36 in the typical three-plane attack formation would be filled entirely with GAM-71s, carrying a total of seven. A total of two decoys could be carried in each bomb bay (except three), and a mixed load was also possible although the Air Force did not specify that it intended to use mixed loads.

To fit in the bomb bay of a B-36, the GAM-71 was relatively small; its wings were folded when it was stowed in the bay. To mimic the radar cross-section of the B-36, it carried radar reflectors.

In February 1955, glide tests of XGAM-71 prototypes began using a modified B-29 Superfortress as the mothership. However, the program was delayed due to funding issues. Convair also had higher priorities. A total of seven flights were conducted before the program was cancelled in January 1956, an event that Jenkins attributes to the imminent B-36 phase-out.
