Grumman TBF Avenger
1941 torpedo bomber aircraft model
The Grumman TBF Avenger (designated TBM for aircraft manufactured by General Motors) is an American World War II-era torpedo bomber developed initially for the United States Navy and Marine Corps and also eventually used by several air and naval aviation services around the world. From 1942 on, production of the Avenger (representing nearly three-quarters of its total production) was subcontracted to a purposely established division of General Motors, the Eastern Aircraft Division.
The Avenger entered U.S. service in 1942 and first saw action during the Battle of Midway, losing five of the six Avengers on its combat debut. The Avenger remained in service to become the most widely used torpedo bomber of World War II, particularly in the Pacific Theater, where it helped to sink numerous surface ships, including the super battleships Yamato and Musashi. The Avenger was also one of the most effective submarine killers in both the Pacific and Atlantic, with about 30 kills, including the cargo submarine I-52. Greatly modified after World War II, the Avenger remained in use until the 1960s.
Design and development
The Douglas TBD Devastator, the U.S. Navy's main torpedo bomber introduced in 1935, was obsolete by 1939. Bids were accepted from several companies, but Grumman's TBF design was selected as the replacement for the TBD, and in April 1940, two prototypes were ordered by the Navy. Designed by Leroy Grumman, the first prototype was called the XTBF-1. It was first flown on 7 August 1941.
This brief starts where responsible research should: with the source description of “Grumman TBF Avenger” as 1941 torpedo bomber aircraft model. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 1941 torpedo bomber aircraft model. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q734103. The Library of Congress control number is sh85057543. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1942, 1935, 1939 and 1940.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
