Aerial torpedo

An aerial torpedo (also known as an airborne torpedo or air-dropped torpedo^[1]) is a torpedo launched from a torpedo bomber aircraft into the water, after which the weapon propels itself to the target.^[2]

First used in World War I, air-dropped torpedoes were used extensively in World War II, and remain in limited use. Aerial torpedoes are generally smaller and lighter than submarine- and surface-launched torpedoes.
