On March 25, the program is to hold a virtual industry day. “The dialogue from this event will be instrumental in developing a comprehensive final RFP, targeted for release in May 2026,” according to a business notice. Firms interested in bidding may receive a tour of a KC-135 at Tinker next month.

In 2022, AFLCMC said that the KC-135’s integrated fuel management panel, fuel management advisory computer, control display units, tank interface unit, and multi-functional displays faced obsolescence in the near future.

In 2023, the program reduced a CCR electromagnetic interference hardening requirement.

“The original KC-135 CCR hardening requirement was established at Level 2 for both the Flight Display System (FDS) and the Fuel System (FS),” AFLCMC said in December 2023. “However, we anticipate the removal of the hardening requirement for the FDS and reduction of the hardening requirement to Level 3 (threshold) and Level 2 (objective) for the FS. Thus, the government supports commercial solutions for the FDS, but expect the FS will require major modifications to meet requirements.”

The week of March 9, U.S. Central Command said that six Air Force personnel died when a KC-135 supporting the Iran operation went down in western Iraq. CENTCOM said that it is investigating the crash, which the command said “was not due to hostile fire or friendly fire.”
