The Grumman C-2 Greyhound is a twin-engine,
Prototype C-2s first flew in 1964, and production followed the next year. The initial Greyhound aircraft were overhauled in 1973. In 1984, more C-2As were ordered under designation Reprocured C-2A or C-2A(R). In 2010 all C-2A(R) aircraft received updated propellers (from four to eight blades) and navigational updates (glass cockpit).

The C-2 has four vertical stabilizers, of which three are fitted with rudders. A single vertical stabilizer large enough for adequate directional control would have made the aircraft too tall to fit on an aircraft carrier hangar deck. The four-stabilizer configuration has the advantage of placing the outboard rudder surfaces directly in line with the propeller wash, providing effective yaw control down to low airspeeds, such as during takeoff and landing. The inner-left stabilizer lacks a rudder, and has been called the "executive tail", as it has nothing to do compared to the other three. A single C-2 (2797) was equipped with an air-to-air refueling probe but this was not installed in other aircraft.
In 1984, the Navy ordered 39 new C-2A aircraft to replace older airframes. Dubbed the Reprocured C-2A or C-2A(R) due to the similarity to the original, the new aircraft has airframe 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 36 C-2A(R)s underwent a critical Service Life Extension Program (SLEP). The C-2A(R)'s lifespan was 10,000 hours, or 15,000 carrier landings; plans require the C-2A to perform its mission supporting battle group operational readiness through 2015. The lower landing limit was approaching for most airframes, and the SLEP will increase their projected life to 15,000 hours or 36,000 landings. Once complete, the SLEP will allow the 36 aircraft to operate until 2027. The SLEP includes structural improvements to the center wing, an eight-bladed NP2000 propeller, navigational upgrades including the addition of GPS and the dual
CAINS II Navigation System, the addition of crash-survivable flight incident recorders, and a
In November 2008, the company also obtained a $37M contract for the maintenance, logistics and aviation administration services over five years for the C-2A fleet assigned to VX-20 test and evaluation squadron at Patuxent River. Northrop Grumman worked on an upgraded C-2 version, and offered to modernize the fleet with components common to the E-2D Hawkeye.
