The British Fleet Air Arm acquired 1,000 TBM/TBF’s from the US through the Lend-
Lease Act. Initially referred to as Tarpon the British eventually began to use the US
designator Avenger with 334 TBM-1C’s becoming Avenger II. The 402 TBF’s actually
built by Grumman were labeled Avenger I’s and were painted in FAA approved
camouflage colors while the Avenger II’s (TBM-1C) were built by Eastern Aircraft a
subsidiary of General Motors were left in the US equivalent colors. With a squadron
flying both versions of the Avenger the only visible difference between the two was the
paint scheme colors. The British manned these aircraft in a similar manner to that of the
US with a 3-man crew. At first the British Avengers were assigned to escort carriers that
patrolled the North Atlantic looking for submarines. It wasn’t long before most Avengers
were reassigned to fleet carriers where they assisted in strikes against the Tirpitz and
shipping in Norwegian waters. The British Avenger was used extensively in the Indian
Ocean and the Pacific and played a major role in many of the attacks on oil fields and
other Japanese facilities. They operated very closely with the USN and took part in a
large number of combined actions but never seem to get the attention and credit they
deserve. Closer to home the Avenger was tasked with patrolling the English Channel for
any U-boats or S-boats that might that might attack the D-Day invasion fleet on their way
to Normandy. These aircraft also received the black and white D-Day stripes so Allied
forces wouldn’t misidentify them as enemy aircraft. The British continued to use the
Avengers into the early 1950’s when they were replaced by the Fairey Firefly.
