Strategic Aerial Refueling Backbone Advanced Remote Vision & FBW Boom Multi-Mission Fuel & Palletized Airlift

Boeing KC-46 Pegasus & Strategic Refueling Tankers

Boeing is the global benchmark for strategic aerial refueling, powering the mobility of allied air forces since the start of the jet age. From the pioneering Boeing KC-135 Stratotanker and the heavy trijet McDonnell Douglas KC-10 Extender to the next generation fly by wire Boeing KC-46A Pegasus, these force multipliers deliver hundreds of thousands of pounds of fuel mid air to extend the reach of global combat air patrols and strategic transports.

KC-46A Pegasus

Boeing KC-46A Pegasus — Advanced Widebody Multi-Role Tanker

The Boeing KC-46A Pegasus is the next generation multi role aerial refueling tanker designed to replace the aging KC-135 fleet. Developed from the commercial 767-2C freighter platform, it features a fly by wire high speed centerline refueling boom capable of offloading 1,200 gallons per minute, wing mounted probe and drogue refueling pods, an advanced Remote Vision System with 3D cameras, and full chemical, biological, and EMP hardening.
