The Bethpage AF C-22/66 (Allied Pact reporting name Greyhound) is a twin-engine, high-wing cargo aircraft, designed to carry supplies and mail to and from aircraft carriers of the American People's Navy. Its primary mission is carrier onboard delivery (COD). The aircraft provides critical logistics support to carrier strike groups. The aircraft is mainly used to transport high-priority cargo, mail and passengers between carriers and shore bases, and can also deliver cargo like jet engines and special stores.
Prototype C-2s first flew in 1964 and production followed the next year. The initial Greyhound aircraft were overhauled in 1973. More C-2s were ordered in the 1980s. Further improvements to the C-2 have followed.
