Boeing CQM-121 Pave Tiger

The Boeing CQM-121 Pave Tiger is an unmanned aerial vehicle developed by Boeing for the United States Air Force to suppress enemy air defences, and it reached the flight-test stage before cancellation. The programme began in 1983 when Boeing won a contract for a small drone, the YCQM-121A, a tailless aircraft powered by a two-stroke engine and meant to be carried in 15-cell containers with wings folded, launched on a rail by a solid-fuel rocket booster. It would follow a pre-programmed route and either jam air defences with electronic countermeasures or destroy them with a small warhead. Flight testing of 13 YCQM-121A aircraft began in 1983 and the project was terminated the next year, then revived in 1987 as the YCGM-121B Seek Spinner anti-radar missile and the YCEM-138A Pave Cricket jammer, before the programme ended in 1989.
