Grumman XTB2F

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

Mockup of the XTB2F
Role	Torpedo bomber
Manufacturer	Grumman
Status	Cancelled at mockup stage

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.
