About this IDV

The Air Force Materiel Command awarded an indefinite-delivery contract to The Boeing Company on July 1, 2023, for ten-year C/KC-135 engineering sustainment support services with a $420 million ceiling. This is a single-award vehicle.

Engineering sustainment services encompass recurring and non-recurring engineering, program management, training, and travel support for the KC-135 aerial refueling tanker. The contract includes a two-year base period and four two-year option periods, with ultimate completion on June 30, 2033. Place of performance includes Tinker Air Force Base, Oklahoma and subordinate component locations across multiple U.S. states and Canada, with additional work supporting foreign military sales for France, Turkey, Chile, and other allied customers.

The originating pre-solicitation notice (posted March 3, 2022) identified this as a sole-source award to Boeing due to proprietary data ownership. Primary NAICS code is 541715 (engineering services); PSC code is R425. The contract utilizes multiple pricing structures across CLINs, including firm-fixed-price, cost-plus-incentive-fee, and cost-plus-fixed-fee arrangements.

Recent task order activity demonstrates sustained drawdown: delivery orders issued under this vehicle from June 2023 through July 2026 total approximately $155 million across recurring and non-recurring engineering sustainment, KC-135 boom structural tube maintenance, proposal preparation costs, and foreign military sales support work. Notable orders include $23.3 million for KC-135 engineering services option 1 (awarded July 1, 2026, through June 30, 2027), $21.1 million for engineering sustainment services option 1 year 1 (awarded August 1, 2025, completing July 31, 2026), and $18.6 million for KC-135 MSG-3 maintenance steering group analysis (awarded September 26, 2024, completing September 26, 2026). All task orders to date have been performed at Oklahoma City Air Logistics Complex and direct to The Boeing Company with no set-aside restrictions.
