The KC-46A is a next-generation multirole tanker aircraft based on the Boeing 767 commercial aircraft. It is intended to replace the oldest of the US Air Force (USAF) KC-135 Stratotanker fleet — some of which are over 50 years old.. The KC-46 will be able to refuel all fixed-wing aircraft through its advanced fly-by-wire boom based on the proven KC-10 boom, and state-of-the-art centerline and wing mounted hose and drogue systems.
