The KC-46A Pegasus tanker continues to broaden the range of aircraft it has refueled during testing, with the successful refueling of a U.S. Marine Corps AV-8B Harrier II on March 1, according to an Air Force news release from the 412th Test Wing. The Boeing and Air Force crew performed the refueling over Washington state.

The Harrier refueled from the KC-46A’s hose and drogue system, as Marine Corps aircraft employ a refueling probe to receive fuel in flight. The KC-46A has three hose and drogue units, one on the aircraft centerline and one under each wing. Each hose and drogue unit supplies up to 400 gallons of fuel per minute, about one-third the rate at which the tanker’s flying boom can pass fuel to aircraft.

The KC-46A had previously refueled an Air Force F-16 with its flying boom system and a Navy F/A-18 Hornet in the first test of its hose and drogue system.
