Torpedo
A self-propelled missile launched from a ship or submarine is commonly referred to as a cruise missile. These missiles are designed to travel at a steady speed and altitude, allowing for precision targeting of ground or sea-based targets. They typically utilize guidance systems such as GPS or inertial navigation to navigate to their intended destination. Examples include the Tomahawk missile, widely used by the U.S. Navy.
The answer to this multiple-choice question was a torpedo. The reason that the question specifies "usually" is that ASW aircraft can launch torpedoes.(The word missile in military usage always means self-propelled weapons.)The ASROC is a rocket-boosted torpedo, and many other types of missiles are launched from ships and submarines, including cruise missiles such as the Tomahawk. Trident (FBM) submarines can launch strategic ICBMs.*All submarine weapons are actually ejected from the vessel prior to its activation: torpedoes are ejected by water impulse, as are SUBROC, Harpoon, and Tomahawk missiles. Their motors start once they've cleared a certain range from the vessel. Ballistic missiles are ejected by air impulse - launch is near the surface, and the missile is ejected into a pocket of air or steam where the rocket motor ignites.
A missile is a self-propelled weapon designed to be launched at a target. It typically carries an explosive payload and is guided by a system that directs it to its intended destination. Missiles are used in military applications for purposes such as defense, offense, and strategic deterrence.
no because torpedos are self propelled, people are too but the are to slow to be "launched" from a torpedo tube.
The term for the self-propelled missile or vehicle is "rocket."The similar proper noun, a New York dance company, is the Rockettes.

Yes - Alvin (DSV-2) is completely battery powered when performing deep ocean operations, when released from its tender.
A rocket powered projectile is typically called a rocket or a missile. It is a self-propelled, guided projectile that uses rocket propulsion to fly.
Lunokhod-1 was the first self-propelled vehicle on the moon.
An aircraft with an engine. A non-self propelled aircraft would be a balloon or a glider.
