The Boeing-built KC-46 tanker is a military version of the 767 commercial aircraft. It is intended to replace the oldest of the U.S. Air Force’s KC-135 Stratotanker fleet -- some of which are over 50 years old.

The KC-46A will be able to refuel any fixed-wing receiver capable aircraft on any mission. This aircraft is equipped with a modernized KC-10 refueling boom integrated with proven fly-by-wire control system and delivering a fuel offload rate required for large aircraft. In addition, the hose and drogue system adds additional mission capability that is independently operable from the refueling boom system.

Two high-bypass turbofans, mounted under 34-degree swept wings, power the KC-46A to takeoff at gross weights up to 415,000 pounds. Nearly all internal fuel can be pumped through the boom, drogue and wing aerial refueling pods. The centerline drogue and wing aerial refueling pods are used to refuel aircraft fitted with probes. All aircraft will be configured for the installation of a multipoint refueling system.

MPRS configured aircraft will be capable of refueling two receiver aircraft simultaneously from special "pods" mounted under the wing. One crewmember known as the boom operator controls the boom, centerline drogue, and wing refueling pods during refueling operations. This new tanker utilizes an advanced KC-10 boom, a center mounted drogue and wing aerial refueling pods allowing it to refuel multiple types of receiver aircraft as well as foreign national aircraft on the same mission.

A cargo deck above the refueling system can accommodate a mix load of passengers, patients and cargo. The KC-46A can carry up to 18 463L cargo pallets. Seat tracks and the onboard cargo handling system make it possible to simultaneously carry palletized cargo, seats, and patient support pallets in a variety of combinations.
