Grumman TBF Avenger — Torpedo Bomber
Open in interactive gallery →

The Grumman TBF Avenger (Eastern Aircraft licence variant designated TBM) was the U.S. Navy's principal carrier-based torpedo bomber from late 1942 onward. Grumman and General Motors's Eastern Aircraft Division built 9,839 TBF/TBM Avengers between 1941 and 1945. The Avenger entered combat at the Battle of Midway on 4 June 1942 — six pre-production aircraft of VT-8 launched from Midway Atoll attacked the Japanese carrier strike force; only one returned. Despite the disaster of its combat debut, the Avenger went on to sink more Japanese ships than any other U.S. carrier aircraft and to serve into the late 1950s in front-line U.S. and foreign service.

The TBF was the first U.S. naval aircraft designed with a fully-enclosed dorsal gun turret. Power: Wright R-2600 Twin Cyclone 14-cylinder radial (1,700 hp). Maximum speed 271 mph; range 1,000 miles; service ceiling 30,100 ft. Crew: three (pilot, gunner/radioman, dorsal-turret gunner / lower-rear gunner). Bomb load: one 22-inch Mk 13 torpedo (2,000 lb) or up to 2,000 lb of bombs internally. Defensive armament: one .50-cal in the dorsal turret + two wing-mounted .50-cals (TBF-1C onward) + one .30-cal in the lower rear position. The internal bomb bay made the Avenger heavier than the obsolescent TBD Devastator it replaced but also let the aircraft carry torpedoes without external drag.

Combat success came after the painful Midway debut. Avengers sank Japanese light carrier Ryujo (Eastern Solomons, August 1942), participated in the sinking of battleship Hiei (Naval Battle of Guadalcanal, November 1942) and battleship Yamato (April 1945), and supported every major Pacific amphibious operation through war's end. The Royal Navy Fleet Air Arm operated about 950 Avengers as Avenger I/II/III against Japanese forces in the Indian Ocean and Pacific 1943-1945. Atlantic-theatre Avengers also sank or damaged about 30 German U-boats during anti-submarine operations from escort carriers.

The Avenger continued in U.S. Navy service through 1954 in anti-submarine and airborne early-warning roles. Foreign operators (Royal Canadian Navy, French Navy, Royal Netherlands Navy, Japanese Maritime Self-Defense Force) flew TBMs into the late 1950s. About 50 Avenger airframes survive in 2026 — more than any other WWII U.S. carrier-based bomber. Several airworthy TBMs serve as fire-bombing aerial tankers (water/retardant drops on wildfires) in Canada, the most-extensive operational use of a WWII airframe in modern civilian service. President George H.W. Bush flew an Avenger as a 19-year-old TBM-1C pilot from USS San Jacinto; he was shot down over Chichi Jima on 2 September 1944 and rescued by the U.S. submarine USS Finback.

For Kids — a shorter, friendlier version

The Grumman TBF Avenger is the U.S. Navy's main torpedo bomber from World War II. It took off from aircraft carriers and dropped torpedoes, which are like underwater missiles, at enemy ships. The plane is big and slow, but tough and reliable.

The Avenger first flew in 1941. It was named to avenge the attack on Pearl Harbor a few weeks earlier. Three crew members rode inside: a pilot in front, a gunner in a bubble on top, and a bombardier in the belly. The bomb bay could carry one 2,000 pound torpedo or several bombs.

The Avenger helped sink the giant Japanese battleship Yamato in 1945. It also flew patrol flights over the ocean, hunting submarines. About 9,839 Avengers were built, more than any other torpedo bomber in history.

Future American President George Bush flew an Avenger in 1944, and was rescued from the sea after his plane was hit by enemy fire. Some Avengers kept flying after the war as water bombers to fight forest fires.

Fun Facts

  • The TBF Avenger was the largest single-engine plane to fly from U.S. Navy carriers in WWII.
  • Future President George H.W. Bush was the youngest Navy pilot of his time and flew an Avenger.
  • The Avenger's bomb bay doors could swallow a 2,000 pound torpedo as long as a small car.
  • Five Avengers vanished over the Bermuda Triangle on a training flight in December 1945, never to be found.
  • Avengers helped sink the Japanese battleship Yamato, the largest battleship ever built.
  • The Royal Navy called its Avengers 'Tarpons' for a while before switching to 'Avenger'.
  • Some Avengers worked as forest-fire water bombers in Canada into the 2010s.

Kids’ Questions

What is a torpedo bomber?

A torpedo bomber is a plane that drops torpedoes at enemy ships. A torpedo is like a small submarine with a motor that runs by itself underwater and explodes when it hits a ship. The plane flies low and slow over the water to drop it.

How big was the Avenger?

The Avenger was huge for a single-engine plane, with a 54-foot wingspan, about the length of two minivans parked end to end. Its wings folded up for storage on aircraft carriers.

Are any Avengers still flying?

Yes, about 12 Avengers still fly at air shows around the world, mostly in the U.S. and Canada. Many more are on display in museums, where you can see their huge folding wings up close.

Notable Operators

U.S. Navy / U.S. Marine Corps
Primary user. Carrier service 1942-1954 in torpedo, dive-bombing, anti-submarine, and airborne-early-warning roles. Sank more Japanese ships than any other U.S. carrier aircraft.
Royal Navy Fleet Air Arm
About 950 Avengers as Avenger I/II/III. Served Indian Ocean and Pacific theatres against Japanese forces 1943-1945. Continued in post-war Royal Navy and later Royal Canadian Navy service.
Royal Canadian Navy / French Navy / others (post-war)
Royal Canadian Navy operated TBMs from carriers HMCS Magnificent and HMCS Bonaventure through the 1960s. French Navy and Royal Netherlands Navy operated TBMs into the late 1950s. Japanese Maritime Self-Defense Force operated 13 TBMs as anti-submarine aircraft 1955-1962.
Civilian fire-bombing operators
Multiple Canadian companies operated TBMs as fire-bombing aerial tankers from the 1950s into the 2010s. About 8 TBMs remain in active fire-bombing service in 2026 — the most-extensive operational use of any WWII airframe in modern civilian service.

Frequently Asked Questions

Was the Avenger at the Battle of Midway?

Yes — six pre-production TBF-1s of Torpedo Squadron 8 (VT-8) launched from Midway Atoll on 4 June 1942 attacked the Japanese carrier strike force. Five aircraft were shot down by Japanese Zeros; only Ensign Albert K. Earnest's Avenger returned, badly damaged. The disaster was the Avenger's combat debut. The same day, SBD Dauntlesses sank four Japanese carriers — winning the battle and the long-range Pacific War.

Did George H.W. Bush fly the Avenger?

Yes — Lt. (jg) George H.W. Bush flew TBM-1C Avengers from USS San Jacinto 1944. On 2 September 1944, his Avenger was hit by Japanese anti-aircraft fire over Chichi Jima; Bush continued his attack run, dropped his bombs, and bailed out before the aircraft crashed. He was rescued by the U.S. submarine USS Finback. Bush was 19 at the time; he became the 41st President of the United States in 1989.

How many TBF/TBM Avengers were built?

9,839 airframes between 1941 and 1945 — 2,290 by Grumman + 7,549 by General Motors's Eastern Aircraft Division. The Avenger is the most-produced single-engine torpedo bomber in history.

What enemy ships did Avengers sink?

Japanese light carrier Ryujo (Eastern Solomons, August 1942), battleship Hiei (Naval Battle of Guadalcanal, November 1942), battleship Yamato (April 1945, joint with U.S. Navy SBDs and SB2Cs), plus dozens of cruisers, destroyers, transports, and submarines across the Pacific Theater. Atlantic-theatre Avengers also sank or damaged about 30 German U-boats from escort carriers.

Are any Avengers still flying?

Yes — about 12 airworthy Avengers in 2026, more than most other WWII U.S. carrier aircraft. About 8 are still in active service as fire-bombing aerial tankers with Canadian forestry-services contractors. Several airshow regulars include the Commemorative Air Force's TBM-3 and the Mid Atlantic Air Museum's TBF-1.
