A single synchronized .30 caliber (7.62 mm) 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 0.30 caliber (7.62 mm) hand-fired machine gun flexibly-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 omitted the cowl-mount synchronized 0.30 caliber (7.62 mm) gun, and replaced it with twin Browning AN/M2 0.50 caliber (12.7 mm) light-barrel guns, one in each wing outboard of the propeller arc, per pilots' requests for better forward firepower and increased strafing ability. There was only one set of controls on the aircraft, and no direct access to the pilot's position existed from the rest of the aircraft's interior. The radio equipment was massive, especially by today's standards, and filled the length of the well-framed "greenhouse" 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.

posited in ''Miracle at Midway'' that the outdated Devastators (and lack of new aircraft) contributed somewhat to the lack of a complete victory at Midway (the four Japanese fleet carriers were sunk directly by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 growing American air superiority, better attack coordination and more veteran pilots, Avengers were able to play vital roles in the subsequent battles against Japanese surface forces. On 24 August 1942, the next major naval aircraft carrier battle occurred at the Eastern Solomons. Based on the carriers and , the 24 TBFs present were able to sink the Japanese light carrier and claim one dive bomber, at the cost of seven aircraft.

The allotment of space for specialized internal and wing-mounted fuel tanks doubled the Avenger's range. By 1943, Grumman began to slowly phase out production of the Avenger to produce

fighters, and the Eastern Aircraft Division of

took over production, with these aircraft being designated TBM. The Eastern Aircraft plant was located in Ewing, New Jersey. Grumman delivered a TBF-1, held together with sheet metal screws, so that the automotive engineers could disassemble it, a part at a time, and redesign the aircraft for automotive style production. This aircraft was known as the "P-K Avenger" ("P-K" being an abbreviation for Parker-Kalon, manufacturer of sheet metal screws).
