The TBD Devastator was the Navy's first all-metal, monoplane torpedo bomber. It was also the Navy's first carrier-based plane to come with an enclosed cockpit, and the first to use main landing gear wheel brakes. While most carrier-based aircraft of the day had manually folded wings for storage aboard ship, the TBD featured hydraulic folding wings. The plane had a crew of three (pilot, bombardier and gunner) and carried a half-ton torpedo. It entered service with the fleet in 1937. One sailor, after looking it over, said: "It's got everything but the kitchen sink."
