Concept: KC-46A refuels Super Hornets

KC-46A concept

September 30/20: Engineering Boeing won a $40 million contract modification for KC-46 engineering, manufacturing, and development. This provides for qualification test of the components and full life qualification of the actuator, as well as for conducting lab test, ground test and flight test verifications. The KC-46A Aerial Refuelling Aircraft has a maximum fuel capacity of 212,000lb. The aircraft is fitted with a flush-mounted air-to-air refuelling receptacle capable of accepting fuel at 1,200gal/min. The tanker is capable of carrying 18 cargo pallets, as well as transporting 58 passengers normally and up to 114 passengers during contingency operations. The tanker aircraft also provides urgent aeromedical evacuation by transporting 54 medical patients. The maximum takeoff weight of the tanker aircraft will be 415,000lb (188,241kg). Work will take place in Seattle, and is expected to be completed December 31, 2023

DID’s FOCUS articles cover major weapons acquisition programs – and no program is more important to the USAF than its aerial tanker fleet renewal. In January 2007, the big question was whether there would be a competition for the USA’s KC-X proposal, covering 175 production aircraft and 4 test platforms. The total cost is now estimated at $52 billion, but America’s aerial tanker fleet demands new planes to replace its KC-135s, whose most recent new delivery was in 1965. Otherwise, unpredictable age or fatigue issues, like the ones that grounded its F-15A-D fighters in 2008, could ground its aerial tankers – and with them, a substantial slice of the USA’s total airpower.

KC-Y and KC-Z buys are supposed to follow in subsequent decades, in order to replace 530 (195 active; ANG 251; Reserve 84) active tankers, as well as the USAF’s 59 heavy KC-10 tankers that were delivered from 1979-1987. Then again, fiscal and demographic realities may mean that the 179 plane KC-X buy is “it” for the USAF. Either way, the KC-X stakes were huge for all concerned.

In the end, it was Team Boeing’s KC-767 NexGen/ KC-46A (767 derivative) vs. EADS North America’s KC-45A (Airbus KC-30/A330-200 derivative), both within the Pentagon and in the halls of Congress. The financial and employment stakes guaranteed a huge political fight no matter which side won. After Airbus won in 2008, that fight ended up sinking and restarting the entire program. Three years later, Boeing won the recompete. Now, they have to deliver their KC-46A.
