The Whitehead Mark 2 torpedo[4] was a Whitehead torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York secured manufacturing rights in 1892.

[1] The Mark 2 was ordinarily assembled into three sections: the warhead, the air flask and the after-body.

[1] The three-cylinder reciprocating engine ran on cold, compressed air which was stored in the air flask, which had a capacity of 7.154 cubic feet at 1350 pounds per square inch.

[5] The Mark 2 guidance component included the Pendulum-and-hydrostat control device which was called the "Whitehead Secret".

The first commissioned U.S. Navy submarine, USS Holland, was armed with three Mark 2 torpedoes.
