An aerial torpedo (also known as an airborne torpedo or air-dropped torpedo) is a torpedo launched from an aircraft into the water, after which the weapon propels itself to the target. They are generally smaller and lighter than submarine- or ship-launched torpedoes.
First used in World War I, aerial torpedoes were used extensively in World War II by torpedo bombers against large surface vessels, especially in aircraft carrier-dominated naval battles of the Pacific War. They remain in limited use today mainly for anti-submarine warfare (ASW) by maritime patrol aircraft and naval helicopters.
An underwater vehicle is any member of the class of watercraft that is intended to operate in the underwater environment, as opposed to surface vessels that only stay afloat on top of water. This article lists the types of underwater vehicle, with a brief description of each type. An underwater vehicle can be crewed or unmanned (which may be remotely operated or fully autonomous), and will generally, but not necessarily, have some form of onboard propulsion system.
