/1,417 kW). The aircraft took 25 gallons of oil and used one gallon per minute at start-up. There were three crew members: pilot, turret gunner and radioman/bombardier/ventral gunner. One .30 caliber machine gun was mounted in the nose, a .50 caliber (12.7 mm) gun was mounted right next to the turret gunner's head in a rear-facing electrically powered turret, and a single .30 caliber hand-fired machine gun mounted ventrally (under the tail), which was used to defend against enemy fighters attacking from below and to the rear. This gun was fired by the radioman/bombardier while standing up and bending over in the belly of the tail section, though he usually sat on a folding bench facing forward to operate the radio and to sight in bombing runs. Later models of the TBF/TBM dispensed with the nose-mounted gun for one .50 caliber gun in each wing per pilots' requests for better forward firepower and increased strafing ability. There was only one set of controls on the aircraft, and no access to the pilot's position from the rest of the aircraft. The radio equipment was massive, especially by today's standards, and filled the whole glass canopy to the rear of the pilot. The radios were accessible for repair through a "tunnel" along the right hand side. Any Avengers that are still flying today usually have an additional rear-mounted seat in place of the radios, allowing for a fourth passenger.

By early June 1942, a shipment of more than 100 aircraft was sent to the Navy, ironically arriving only a few hours after the three carriers quickly departed from Pearl Harbor

. Unfortunately, both types of torpedo bombers suffered heavy casualties. Out of the six Avengers, five were shot down and the other returning heavily damaged with one of its gunners killed, and the other gunner and the pilot injured. Nonetheless, the US torpedo bombers were credited with drawing away the Japanese combat air patrols so the American dive bombers could successfully hit the Japanese carriers.

 argued in Miracle at Midway that the outdated Devastators (and lack of new aircraft) contributed somewhat to the lack of a complete victory at Midway (the four Japanese fleet carriers were sunk directly by dive bombers instead). Others pointed out that the inexperienced American pilots and lack of fighter cover were responsible for poor showing of US torpedo bombers, regardless of type. Later in the war, with improving American air superiority, attack coordination, and more veteran pilots, Avengers were able to play vital roles in the subsequent battles against Japanese surface forces.
