The Grumman C-1 Trader was a carrier-based transport aircraft designed to carry passengers, mail, supplies, and priority cargo between shore bases and aircraft carriers operating at sea. Entering U.S. Navy service in the 1950s, the twin-engine, propeller-driven Trader was developed from the S-2 Tracker and became an important Carrier Onboard Delivery (COD) aircraft. Its folding wings allowed it to fit into the confined spaces of a carrier, while its rugged landing gear and arresting hook enabled it to make demanding landings on a moving flight deck. The C-1 could transport personnel and essential supplies ranging from replacement parts and equipment to mail from home, providing an important logistical connection for sailors during long deployments. Serving the Navy for more than three decades, the C-1 Trader performed a less glamorous but vital role in carrier operations, helping keep ships, aircraft, and crews supplied while operating far from shore.
