Design and development

The CQM-121 program began in 1983, with Boeing being awarded a contract for the development of a small drone aircraft that was intended for the suppression of enemy air defenses.[1] The resulting YCQM-121A, given the code name "Pave Tiger", was a tailless aircraft powered by a two-stroke engine.[2] The drones were to be fitted in 15-cell containers with wings folded; the sides of the container would open to allow for launch on a rail using a solid-fuel rocket booster. The aircraft would then follow a pre-programmed route, and could either use electronic countermeasures to suppress air defense systems, or use a small warhead to directly destroy them.[3]

Operational history

Flight testing of the 13 YCQM-121A aircraft began in 1983, however the following year the project was terminated.[3] The aircraft was resurrected in 1987, however, as an alternative to the AGM-136 Tacit Rainbow anti-radar missile; the anti-radar version, designated YCGM-121B and codenamed "Seek Spinner", first flew in 1988.[4] It was equipped with a warhead for the destruction of enemy radars, and could loiter while awaiting detection of an enemy radar set.[3] The program was terminated in 1989.[5]

Also in 1987, the U.S. Air Force ordered an electronic countermeasure version of the aircraft, given the designation YCEM-138A Pave Cricket. Equipped with an AN/ALQ-176 jammer, the program was also cancelled in 1989.[6]
