/ Grumman Trader
The Grumman C-1 Trader is a carrier onboard delivery (COD) variant of the Grumman S-2 Tracker.
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.
