Fleetwings XBQ-1

The Fleetwings BQ-1 was an early expendable unmanned aerial vehicle — referred to at the time as an “assault drone” — developed 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 its first flight.

The difference to the Fleetwings XBQ-2 was the use of Franklin O-405-7 opposed piston engines instead of the XBQ-2s Lycoming XO-435 opposed piston engines
