- It has a maximum takeoff weight of 415,000 pounds and a maximum fuel capacity of 212,000 pounds.
- The aircraft is powered by two Pratt & Whitney PW4062 high-bypass turbofan engines, each producing 64,000 pounds of thrust.
- The KC-46 features advanced avionics, including a digital flight control system and a state-of-the-art communication suite.
- The aircraft has a crew of three, including a pilot, a co-pilot, and a boom operator.
Design and Development
The development of the KC-46 began in the early 2000s, with Boeing winning the contract to build the new tanker aircraft in 2011. The company’s proposal, which was based on its 767 commercial airliner, beat out a rival bid from Airbus. The KC-46 is designed to be a more efficient and capable tanker than its predecessors, with a range of advanced features, including a digital flight control system, a state-of-the-art communication suite, and a advanced refueling system. The aircraft’s design also incorporates a number of safety features, including a advanced weather radar system and a terrain avoidance system.The KC-46 has a maximum takeoff weight of 415,000 pounds and a maximum fuel capacity of 212,000 pounds, making it an ideal platform for refueling a wide range of aircraft, from small fighters to large transport planes. The aircraft is powered by two Pratt & Whitney PW4062 high-bypass turbofan engines, each producing 64,000 pounds of thrust. This allows the KC-46 to cruise at speeds of up to Mach 0.80 and reach altitudes of up to 41,000 feet.
Operational Capabilities
The KC-46 is designed to be a highly flexible and adaptable aircraft, capable of performing a wide range of missions.
