The C-20G is a Gulfstream IV aircraft capable of all-weather, long-range, high speed non-stop flights between nominally suited airports. It is manufactured by Gulfstream Aerospace Corporation Savannah, Georgia and is powered by two Rolls-Royce Limited Tay MK611-8 turbofan engines equipped with thrust reversers. The aircraft may be configured for cargo operations, passenger operations or combinations of the two. The C-20G normally operates with a crew of four and can carry up to 26 passengers, 6,000 pounds of cargo, or combinations of passengers and cargo. With passengers seats removed the aircraft may be modified to the following configurations: three pallets/no passengers, two pallets/eight passengers, and one pallet/fourteen passengers. With a full complement of seats installed, the aircraft is capable of accommodating up to twenty-six passengers and a crew of four. A hydraulically-operated cargo door is installed on the starboard side of the aircraft to facilitate loading and unloading of cargo. A ball roller cargo floor is capable of accommodating palletized cargo. A walk-in baggage area of157 cubic feet, fully pressurized, is accessible from the cabin.
The high-speed, medium-lift, long-range aircraft has been used extensively to support the fleet in regions where suitable airfields for refueling are unavailable or undesirable or where time constraints dictate minimizing fuel stops. All four Navy C-20Gs are assigned to the Naval Air Reserve. The C-20G aircraft are operated Fleet Logistics Support Squadron Four Eight (VR-48) and Marine Air Support Detachment (MASD) at Naval Air Facility, Andrews Air Force Base, Washington, DC and at Fleet Logistics Support Wing Detachment, Marine Corps Base, Kaneohe Bay, Hawaii.
The C-20G aircraft was procured as a commercial-derivative aircraft certified under an FAA Type certificate. Throughout its life, the aircraft has been operated and organically and commercially supported by the Navy using a combination of Navy and FAA processes, procedures and certifications. It continues to be maintained organically and commercially at all levels of maintenance, and relies on COTS/NDI components to support airworthiness. Aircraft modification efforts are “turnkey” projects (procurement and installation) implemented as part of competitively awarded maintenance contracts. Where extensive integration efforts are required, the non-recurring engineering phase, including test and certification, is typically performed by Gulfstream Aerospace Corporation under a sole-source engineering contract with the Navy.
