The Fleetwings BQ-1 was an early expendable unmanned aerial vehicle — referred to at the time as an "assault drone" — developed by Fleetwings during the Second World War for use by the United States Army Air Forces.

Only a single example of the type was built, the program being cancelled following the crash of the prototype on a test flight.

Fleetwings was contracted to build a single XBQ-1 assault drone,[1] powered by two Franklin O-405-7 opposed piston engines, and fitted with a fixed landing gear in tricycle configuration.

[1] Following trials of the television-based command guidance system using a PQ-12 target drone, and earlier trials of the XBQ-2A, the XBQ-1 flew in May 1944; however, the aircraft crashed on 17 July 1944 due to engine failure just after take-off from Wright Field.
