The US Navy took a long time to accept twin-engine aircraft for combat on aircraft carriers during World War II. The Grumman F7F Tigercat was the first twin-engine aircraft to be accepted, but it came too late to see action in the war. Only the latest model, F7F-4N, was certified for carrier operations, while the others operated from land bases.
During the latter part of the war, the US Navy wanted to replace its successful Grumman TBF Avenger torpedo bomber. Many attempts were made, including the B. XTB2F-1, but it was too big and heavy for carrier use and was discontinued. The Navy then looked to an improved version of the F7F Tigercat, proposed by Grumman as the "G-66 model."
In August, a contract was signed for two prototypes, designated XTSF-1. The Navy wanted a fighter jet capable of launching torpedoes and exploring the Pacific Ocean, so range was crucial. Grumman engineers made modifications to the F7F-2 airframe, including changes to the radar and integrating the TBF's bomb bay into the Tigercat's fuselage.
Overall, the US Navy faced challenges in accepting twin-engine aircraft for carrier combat, but eventually, the Grumman F7F Tigercat was considered, although it missed the opportunity to serve in World War II.
