The GT-1 (Glide Torpedo 1) was an early form of stand-off weaponry developed by the United States Army Air Forces during World War II.

Intended to deliver an aerial torpedo at a safe range from the launching aircraft, the weapon proved successful enough in testing to be approved for operational use, and the GT-1 saw limited use in the closing stages of the war.

The GT-1 was derived from the GB-1 series of glide bombs, developed by Aeronca for the United States Army Air Forces.
