The KC-46A is based on the commercial Boeing B-767-2C aircraft. The aircraft are modified to fulfill the Multi Role Tanker Transport mission.

The numbers reported in the aircraft ordered column are based on the US DoD contract awards. See further comments below.


Boeing received a (FMS) contract to deliver the first KC-46A to the Japanese Air Self Defence Force. Work is expected to be completed by February 28, 2021.

The Defense Security Cooperation Agency (DSCA) approved the possible sale of four KC-46As and related equipment, training and support through FMS to the government of Japan on September 21, 2016. The Japanese Air Self Defense Force intends to purchase three aircraft. One KC-46A is budgetted in fiscal year 2017. A contract to Boeing by the US DoD for the purchase of the KC-46A has not been awarded yet. 404 Hikotai based at Komaki Air Base (Nagoya international airport) operates four KC-767J aircraft.

United States:

The USAF plans to purchase 179 KC-46As to replace the KC-10 and KC-135 aircraft in service.

KC-46A - N50217 - the seventh aircraft of the KC-46 program and the first aircraft to be delivered to the USAF made its maiden flight on December 5, 2017. During the 3,5 hour flight flew to a maximum height of 39.000ft and completed several tests.

The first KC-46A will be delivered in October 2018. It will be delivered to the 22nd ARW. Delivery of 17 new tankers will take place at a rate of three per month (assummed one in October and 1 April to complete the first 17):

22nd ARW and associate 931st ARW are slated to operate 36 KC-46As.

The first aircraft should have been delivered in August 2017 however certifications and other issues resulted in several revisions of the delivery scheme.

The 97th AMW and 22nd ARW are the first wings to receive the KC-46A. The 931st ARW is a classic associate unit using aircraft from the 22nd ARW when required. Within the 931st ARW the 18th ARS is assigned the KC-135R. On April 2, 2017 the wing activated the 924th ARS which will become the first AFRC dedicated KC-46A squadron. The 924th ARS was operating the KC-135R when it was deactivated at Castle AFB, California in 1992. More than 20 Pegasus aircraft will be assigned to McConnel AFB.

The aircraft numbers which will be operated by the squadrons were provided in press releases with the exception of the 157th ARW and 916th ARW. There the number of aircraft assigned to the wings are assumed.

In the latest round of Pegasus basing decisions both KC-10A wings, 60th and 305th AMWs currently operating 59 aircraft, have been selected to receive the KC-46A.
