Design and development

The C-1 Trader grew out of a need by the United States Navy for a new anti submarine airplane. In response to this Grumman began development on a prototype twin-engine, high-wing aircraft which it designated the G-89. In 1952 the Navy designated this aircraft the XS2F-1 and flew it for the first time on December 4 that year. During the rest of the 1950s three major variants emerged, the C-1 Trader being one of them. The C-1 (originally the TF-1) was outfitted to carry nine passengers or 3,500 pounds (1,600 kg) of cargo and first flew in January 1955.

Operational history

Throughout the 1960s and 1970s the C-1 Trader carried mail and supplies to aircraft carriers on station in the Pacific Ocean during the Vietnam War and also served as a trainer for all-weather carrier operations. Over its production life 83 C-1 Traders were built, of which four were converted into EC-1A Tracer electronic countermeasures aircraft. The last C-1 was retired from USN service in 1988; it was the last radial engine aircraft in U.S military service. As of 2010, approximately ten were still airworthy in civil hands, operating as warbirds.

In August 2010, Brazilian Naval Aviation announced that it will buy and modernize eight C-1 to serve in carrier onboard delivery (COD) and aerial refueling roles for use on its aircraft carrier São Paulo.^[1]

This aircraft was modified with the Grumman E-1 Tracer type radome assembly (but no radar) and twin tails and served (under the designation XTF-1W) as the aerodynamic prototype for the E-1. After testing, it reverted to the transport role, (as C-1A) with radome removed but retaining the twin tails. Throughout, this aircraft retained the S-2/C-1 upward folding wings, not the E-1 wing fold which were necessitated (by the radome atop the fuselage) to fold wings back along the sides of the fuselage.^[5]
