Whitehead Mark 3 Torpedo

Whitehead Mark 3 torpedo (1894-1922): The first self-propelled torpedo. (The word 'torpedo' derives from the name of the torpedo fish, a type of ray that stuns its prey with an electric shock.)

Mark 14 torpedo

Mark 14 torpedo (1931-1980): The standard torpedo used in World War II. Early issues with its Mark VI exploder caused many torpedoes to miss, explode prematurely, or literally run into their targets without detonating.

Mark 37 torpedo

Mark 37 torpedo (1957-1987): An electrically-propelled torpedo developed after World War II. (Note: The green torpedo below the Mark 14 is another version of a Mark 37 torpedo.)

Mark 48 torpedo

Mark 48 torpedo (1972-present): The torpedo carried on subs today. After launching, it can be guided by its mother sub via a wire that connects the two throughout the weaponís journey to its target. The torpedo can also search for a target using its own active and passive sensors and, if it misses on the first pass, can circle around for a second attempt.

Mark 49 antisubmarine mine

Mark 49 antisubmarine mine: This mine (the black weapon in the photo) was typically launched from a sub, but could be launched from the air.


UUM-44 SUBROC (1965-1989): This rocket was launched from a subís torpedo tube, flew through the air, and then dove back into the water to explode near its target.
