TBF-1 Avenger, Grumman.

Industrial powers of Grumman were not sufficient that the General Motors Company was also contracted to build airplane Avenger, under the designation TBM-1, beginning in September 1942.

Power plant: 14-cylinder radial engine of air cooling Wright R-2600-20 Cyclone 1900 hp (1417 kw), three-blade a screw. Additional expendable tanks on 20 l were fixed on external outer wings. For flight on ferry range in bomb bay the expendable tank on 1040 l could be fixed.

Till September, 1945 7546 airplanes TBM of various modifications were produced.

Over 1,000 TBF/TBMs (initially called Tarpon Mk I, and later designated Avenger Mk I) were also used by the Royal Navy's Fleet Air Arm in both Atlantic and Pacific theaters.
