Martin AM Mauler airplane model. The Martin AM Mauler was a shipboard attack aircraft of the United States Navy. Designed during World War II, the aircraft did not enter production until well after the war after a number of problems. One hundred fifty-one aircraft were built, but they did not last long in Navy service, the smaller and simpler Douglas AD Skyraider proved to be a superior aircraft. Active-duty squadrons abandoned the Mauler in 1950, and it lasted through 1953 in reserve units.
