Background
The Grumman TBF Avenger was designed as a torpedo bomber to replace the TBD Devastator. The Devastator had been one of the first modern torpedo bombers for the US Navy but it was lacking is speed, firepower and armor protection. The Avenger entered production in 1942 and soon proved itself to be the perfect fit for the job. To meet production demands, General Motors’ Eastern Aircraft Division started production and eventually produced the majority of all Avengers. These were designated TBM.
Late in its production life, the Avenger was modified for anti-submarine warfare. Some of these featured an AN/APS-4 radar pod under the starboard wing and a searchlight pod under the port wing. In some cases, the rear turret was removed and the radar operator was housed in an extended rear canopy.
