Grumman Avenger in British Service

Initially called the Tarpon when in British Royal Navy Fleet Air Arm service, the Grumman Avenger was renamed along with other US Navy aircraft to adopt US names for American built aircraft.

The first 402 Grumman TBF-1s delivered were designated Tarpon GR.I (later changed to Avenger), 334 General Motors built TBM-1s were called the Avenger Mk II, and 334 TBM-3 were designated the Mk III.

Royal Navy Avengers took part in the Battle of the Atlantic, operating from escort carriers. In the Arctic they escorted convoys to Russia. Avengers also laid mines off the Norwegian coast ana participated in the D-Day landings under RAF control.

In the Far East, FAA Avengers attacked the oil refineries in Sumatra, which significantly curtailed the production of oil for the Japanese military. They also undertook raids on Sakishima Gunto and Formosa and on the Japanese home islands at the end of the war.

Three Avengers were modified to carry the Highball “bouncing bomb” (given the new codename Tammany Hall), but when trials were unsuccessful, they were returned to standard configuration and passed to the Royal Navy.

One hundred USN TBM-3Es were supplied to the Fleet Air Arm in 1953 under the US Mutual Defense Assistance Program. The Avengers were fitted with British equipment by Scottish Aviation and delivered as the Avenger AS.4 to several FAA squadrons including No. 767, 814, 815, 820 and 824. The aircraft were replaced from 1954 by Fairey Gannets.

One Avenger was modified to test in flight the British-designed Frazer Nash F.N.95 remotely-controlled barbette intended for use on the Fairey Spearfish
