The Grumman C-2 Greyhound was a carrier-based transport aircraft designed to deliver passengers, mail, supplies, and critical cargo between shore bases and U.S. Navy aircraft carriers at sea. Entering service in the 1960s, the twin-engine turboprop Greyhound performed the vital Carrier Onboard Delivery (COD) mission and was developed from the E-2 Hawkeye, sharing its distinctive high wing, powerful engines, and rugged carrier-capable design. Its spacious cargo compartment could accommodate personnel, aircraft parts, equipment, and other urgently needed supplies, while folding wings allowed the aircraft to be stored efficiently aboard crowded carrier decks. For generations of sailors, the arrival of a C-2 often meant fresh supplies, replacement personnel, and eagerly awaited mail from home. Serving for more than five decades, the C-2 Greyhound provided an essential logistical lifeline between aircraft carriers and the shore, helping keep carrier operations running while ships remained deployed thousands of miles from home.
