Grumman XTB2F

TB2F
Role	Torpedo bomber
Manufacturer	Grumman
Status	Cancelled at mockup stage

The Grumman TB2F was a prototype, twin-engined torpedo bomber, intended as Grumman's successor to the successful TBF Avenger. However, only a mockup was ever constructed.

In 1944, during World War II, the Midway class aircraft carriers were being built, and Grumman attempted to design a new torpedo bomber to accompany those carriers. However, it was soon decided that, among other difficulties, it would be impracticable to efficiently deploy twin-engined aircraft of this size from an aircraft carrier, and the plans were scrapped.
