They actually saw some action in 1944: These vehicles took off from their carrier and were guided by radio control from a TBD Avenger. The interesting thing is that they were equipped with a TV camera and the last part of the flight was guided by the operator thanks to the images transmitted from the "Drone". From what I understood and seen IMHO they were rather REMOTELY (edit) guided missiles. From Wiki. (I take notice in Odissey channel). The Interstate TDR was an early unmanned combat aerial vehicle — referred to at the time as an "assault drone" — developed by the Interstate Aircraft and Engineering Corporation during the Second World War for use by the United States Navy. Capable of being armed with bombs or torpedoes, 2000 aircraft were ordered, but only around 200 were built. The type saw some service in the Pacific Theater against the Japanese, but continuing developmental issues affecting the aircraft, along with the success of operations using more conventional weapons, led to the decision being made to cancel the assault drone program in October 1944. Interstate TDR - Wikipedia I found many videos in the internet.
