Boeing has been awarded a contract to deliver two additional KC-46A Pegasus tankers to the Japan Air Self-Defense Force (JASDF), bringing the total on contract for Japan to six. Boeing delivered the first KC-46A Pegasus tanker to Japan in October 2021, and a second in February 2022.

«The unmatched versatility and multi-mission capabilities of the KC-46A Pegasus tanker further support JASDF’s air mobility mission», said James Burgess, vice president and KC-46A Pegasus program manager. «The growing global KC-46A Pegasus fleet increases the interoperability advantages for our customers, ensuring mission readiness as well as value for their investment».
Designed to refuel all allied and coalition military aircraft compatible with international aerial refueling procedures, the proven KC-46A Pegasus has flown more than 10,000 sorties and is delivering millions of pounds of fuel every month to allied forces around the globe. In addition to refueling, the KC-46A Pegasus delivers multi-mission capabilities necessary for the 21st century fleet, including data connectivity and personnel, cargo and aeromedical transportation.
«This additional KC-46A Pegasus acquisition reinforces the U.S.-Japan security alliance to support security and stability throughout the Pacific region», said Will Shaffer, president of Boeing Japan. «Boeing is proud of our enduring partnership with Japan, and we look forward to supporting the nation’s KC-46A Pegasus fleet that will fly for decades to come».
Boeing has delivered 67 KC-46A Pegasus tankers, including 65 to the U.S. Air Force and two to Japan. Built on the proven 767 airframe that has more than 1,200 delivered – and with more KC-46A Pegasus aircraft operational globally than any tanker except the Boeing-built KC-135 Stratotanker – the Pegasus also provides crucial mission reliability for global customers.
The contract was awarded by the U.S. Air Force through the Foreign Military Sales process. Boeing builds KC-46A Pegasus aircraft for the U.S. Air Force, the JASDF and other allied customers on its 767 production line in Everett, Washington. In addition, Boeing’s Japanese partners produce 16 percent of the KC-46A Pegasus airframe structure. The JASDF also operates four earlier generation Boeing-built KC-767 aircraft.
