Voices of WW2(@VoicesofWW2):TDN-1 attack drone on its first (piloted) test flight from Traverse City, Michigan, United States, 19 May 1943. The pilot was Navy Lieutenant C.C. Corley. The TDN-1 was a World War II era American assault drone developed by the Naval Aircraft Factory for the US Navy. It was one of the earliest operational attack drones and a precursor to the better known TDR-1 built by Interstate Aircraft. The program grew out of the Navy's "Project Option," an effort led by Rear Admiral Delmar Fahrney to develop television guided unmanned aircraft that could deliver torpedoes or bombs against heavily defended targets without risking a pilot. The TDN-1 was designed in 1942 and first flew in 1943. It was a twin engine, mid wing monoplane built largely of non strategic materials such as wood, with fixed tricycle landing gear to simplify mass production and keep critical aluminum free for combat aircraft. It was powered by two Lycoming O-435-2 air cooled engines of about 220 horsepower each. The drone could carry a 2,000 pound bomb or a Mark 13 aerial torpedo slung beneath the fuselage. A small cockpit allowed a pilot to ferry the aircraft manually, but in combat configuration it was meant to fly unmanned. Control came from a "mother" aircraft, typically a TBM Avenger fitted with an RCA Block television receiver and a radio command link. A small TV camera in the drone's nose transmitted a live picture back to the controller, who steered it onto the target with a joystick. Maximum speed was roughly 140 miles per hour, with a range of about 425 miles. It was slow and not especially robust, which limited its tactical usefulness. Around 100 airframes were built, mostly at the Naval Aircraft Factory in Philadelphia and at a Navy run plant in Clearwater, Florida. The TDN-1 was used mainly for training drone controllers and developing tactics. Operational combat missions were carried out by the improved TDR-1 with Special Task Air Group One (STAG-1) in the Solomon Islands in 1944, where assault drones struck Japanese ships and shore positions before the program was cancelled later that year as conventional air power proved sufficient. Although it never saw front line combat itself, the TDN-1 helped prove that television guided, radio controlled strike aircraft were technically feasible, foreshadowing later cruise missiles and modern attack drones.
