From Wikipedia, the free encyclopedia
The Grumman Sto-Wing (sometimes stylized as STO-Wing) is a patented wing aftwards-folding system. Pioneered on the Grumman F4F-4 Wildcat, it has been used since World War II on a number of Grumman-designed carrier aircraft. A version of this system is still in use in the 21st century on the Northrop Grumman E-2 Hawkeye shipboard airborne early warning (AEW) aircraft and its C-2 Greyhound cargo aircraft derivative.
