Editor’s Note: All eyes are on Boeing’s KC-46A Pegasus as it continues its journey through flight test. The KC-X program has been wrought with controversy, so the fact it recently conducted its first aerial refueling is a huge step forward. We can only hope things will continue to go smoothly so Air Mobility Command can start fielding this aircraft and begin replacing its ancient fleet of KC-135s.
Boeing’s KC-46 tanker marked a key milestone Sunday by successfully completing its first aerial refueling test.
During the Jan. 24 flight, the Boeing and US Air Force test team completed a series of test points with the aircraft before successfully transferring 1,600 pounds of fuel to an F-16 fighter jet, according to a company statement. The KC-46, a militarized version of the company’s 767 commercial jet, took off from Boeing Field in Seattle, Washington.
During the 5 hour, 43 minute flight, the tanker’s refueling “boom” – a rigid, telescoping tube that an operator on the aircraft extends and inserts into a receptacle on the receiving aircraft for fuel transfer – remained stable and performed well, the statement reads.
The test event kicks off the plane’s “Milestone C” aerial refueling demonstration, required before beginning low-rate initial production.
“Today’s flight is an important milestone for the Air Force/Boeing team,” said Col. Christopher Coombs, Air Force KC-46 system program manager, according to the statement. “We have a lot of work yet to do, but this is an exciting time for the airmen who are preparing to fly, maintain and support the KC-46 Pegasus for decades to come.”
Air Force fixed-wing assets use the boom system for aerial refueling, with a planned 1,200 gallons-per-minute transfer rate from the KC-46. Air Force helicopters and most Navy and Marine Corps aircraft, on the other hand, use the “probe-and-drogue” method of refueling. During this event, fuel passes from the tanker’s “drogue” refueling basket, which trails from the plane via a flexible hose, through a “probe,” a rigid, retractable arm placed on the receiver aircraft’s nose or fuselage.
Yesterday’s test event marks another sign the KC-46 program is on track after several setbacks in 2015. The test plane successfully completed first flight in September after it was initially planned for 2014.
