The US Air Force has issued a $127,430,000 order to Gulfstream Aerospace Corporation for the acquisition of 2 C-37B aircraft. The C-37B is the military designation of the Gulfstream G550 business jet.
The aircraft is known to operate in VIP configuration with the US Air Force (1 aircraft), the US Navy (3 aircraft), the US Army (1 aircraft) whereas the US Coast Guard has dedicated its sole aircraft as a command and control platform.
Derived from the civilian Gulfstream G550, the C-37B is slightly different than the C-37A which is the military derivative of the Gulfstream G500. The G500 (or GV) and the G550 both share the same fuselage, but use noticeably different engines. The Rolls Royce BR710C4-11 fitted to the C-37B deliver slightly more thrust than Rolls Royce BR710A1-10 that power the C-37A (15,385 pounds for the C-37B versus 14,750 pounds for the C-37A).
The C-37 aircraft perform long range intercontinental missions carrying up to 12 people on board at cruising altitudes between 41,000 and 51,000 feet.
