C-2 Greyhound Grumman
C-2 Greyhound
Carrier Onboard Delivery Transport

DESCRIPTION:
Based on the success of the E-2 Hawkeye AEW aircraft, Grumman proposed a carrier onboard delivery (COD) derivative to transport vital supplies or personnel between ships at sea and distant shore bases. Such an aircraft allows the carrier battle forces to remain at peak operability even when too far from shore for supplies to be ferried by helicopter.

Once the US Navy accepted the design, Grumman began production of 19 aircraft. These planes differ from the E-2 in the deletion of the rotating radome, having a larger diameter fuselage, addition of rear cargo doors, strengthening of the fuselage deck for heavy loads, and elimination of the tailplane dihedral made necessary by the radome installation. The resulting wider and deeper fuselage provides space for up to 39 troops or personnel, 20 stretchers and attendants, or 10,000 lb (4,535 kg) of cargo pallets.

The initial 19 C-2 aircraft supplemented the older C-1 Trader in the COD role until the mid-1980s when the Navy ordered an additional 39 C-2A Greyhounds. This second batch of aircraft was based on the updated E-2C airframe and incorporated updated avionics and engines as well as improved passenger accomodations. While the older C-2s were withdrawn from service by 1987, those of the second batch remain in use, and two C-2 Greyhounds equip each carrier air wing.

Plans had called for the C-2 to be replaced by a new plane called the Common Support Aircraft, but that effort appears to have been shelved. The C-2 will likely remain in service until at least 2020.
