Naval Aircraft Factory TDN Assault Drone
The Naval Aircraft Factory TDN was an early unmanned combat aerial vehicle – referred to at the time as an “assault drone” – developed by the United States Navy’s Naval Aircraft Factory during the Second World War. Developed and tested during 1942 and 1943, the design proved moderately successful, but development of improved drones saw the TDN-1 relegated to second-line duties, and none were used in operational service.
