The C-2 Greyhound, a derivative of the E-2 Hawkeye, shares wings and power plants with this E-2, but has a widened fuselage with a rear loading ramp. The first of two prototypes flew in 1964 and production began in '65. It replaced the piston-engined C-1 Trader in the COD role. The original C-2A aircraft were overhauled to extend their operational life in 1973. In 1984, the Navy ordered 39 new C-2A aircraft to replace the first series. Dubbed the Reprocured C-2A (C-2A(R)) due to the similarity to the original, the new aircraft has many improvements and better avionics. The older C-2As were phased out in 1987, and the last of the new models was delivered in 1990. The survivors now are upgraded with 8-bladed propellors, as can be seen on C-2A 162142 of VX-20 at Le Bourget.
