Boeing Names KC-46 Tanker Suppliers


Nationwide team to support US Air Force aerial refueling aircraft

ST. LOUIS, -- The Boeing Company [NYSE: BA] today announced the supplier team that will provide key components for the U.S. Air Force’s KC-46 Tanker. The Air Force selected Boeing on Feb. 24 to replace 179 Eisenhower-era KC-135 aerial refueling aircraft.

“Delivering 18 combat-ready tankers to the U.S. Air Force in 78 months is our priority as a company, and it will take a talented, committed supplier team to help get that done,” said Maureen Dougherty, Boeing KC-46 vice president and program manager. “We’re fortunate to have a strong defense industry team of domain experts working side-by-side to provide a new generation of aerial refueling.”

The KC-46 Tanker team will include more than 800 suppliers in more than 40 states and support approximately 50,000 total U.S. jobs. Major suppliers include:

Based on the proven Boeing 767-200ER commercial aircraft, the KC-46 is powered by two Pratt & Whitney PW4062 engines and will be flown by three aircrew members (pilot, co-pilot, boom operator) with additional permanent seating for 12 aircrew.

The KC-46 has a maximum fuel capacity of 212,000 pounds and is equipped with a flush-mounted, air-to-air refueling receptacle that is capable of onloading fuel at 1,200 gallons per minute.

Boom operators will control the refueling systems from the crew compartment via the AROS and a series of cameras mounted on the tanker’s fuselage that provide a 185-degree field of view, as well as a camera on the boom that captures 3-D video. This advanced system allows the boom operator to refuel all fixed-wing receiver aircraft, anytime, on every mission, to include simultaneous multi-point refueling from the wing air refueling pods. The KC-46 refueling systems include a digital fly-by-wire boom capable of offloading 1,200 gallons of fuel per minute, as well as a permanent centerline drogue system and removable wing air refueling pods that can each offload 400 gallons of fuel per minute.

Featuring a maximum takeoff weight of 415,000 pounds, the tanker will carry 18 463L cargo pallets (the same number of pallets as the Air Force’s Boeing C-17 airlifter) and is capable of transporting 58 passengers normally and up to 114 passengers during contingency operations. This multi-mission tanker aircraft also will provide urgent aeromedical evacuation by transporting 58 medical patients (24 litters/34 ambulatory).

Boeing will build the KC-46 Tanker using a low-risk approach to manufacturing by a trained and experienced workforce at existing facilities in Everett, Wash., and Wichita.
