https://en.wikipedia.org/wiki/Grumman_C-1_Trader
The Grumman C-1 Trader is a carrier onboard delivery (COD) variant of the
Grumman S-2 Tracker. It was replaced by a similar version of the Northrop
Grumman E-2 Hawkeye, the Grumman C-2 Greyhound.
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.

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 87 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 airframes to serve in carrier onboard delivery (COD) and
In 2011 contract was signed with Marsh Aviation to convert four ex-US Navy C-1A
Trader airframes into KC-2 Turbo Traders. The first KC-2 prototype flight is
expected for November 2017 and the delivery of the first operational aircraft is
scheduled for December 2018.
