The Martin AM Mauler (originally XBTM) was a single-seat shipboard attack aircraft built for the United States Navy. Designed during World War II, the Mauler encountered development delays and did not enter service until 1948 in small numbers. The aircraft proved troublesome and remained in front-line service only until 1950, when the Navy switched to the smaller and simpler Douglas AD Skyraider. Maulers remained in reserve squadrons until 1953.
