Research Enabling Procurement for Aerospace Systems (REPAS)

The Department of the Air Force established REPAS, a Master IDIQ for propulsion, power, and thermal management technology research and development, on March 31, 2021, with a combined potential value of $96 million and a shared ceiling across two awardees. The vehicle's ordering period closed on April 25, 2026; no new task orders may be placed.

This vehicle is no longer active for new procurement. Eight task orders have been awarded against the $96 million ceiling, with $62.2 million obligated to date. Ordering activity peaked at award in 2021 with six initial orders placed simultaneously; subsequent awards were issued in 2023 and 2024, with no orders placed in the final two years before the ordering deadline.

Scope spans component design and development, subsystem integration, and bench, rig, and engine testing across propulsion, structures, turbomachinery, fuels, and high-speed research programs. All work is performed on-site at Air Force Research Laboratory facilities. Task orders use Cost Plus Fixed Fee pricing and span durations from roughly three to four years, with ceiling values ranging from $1.5 million to $29.8 million.

Competition is highly concentrated. Arctos Technology Solutions, LLC holds six of eight orders representing $66.5 million in potential value, while the University of Dayton holds the remaining two orders valued at $29.4 million combined. All task orders fund Air Force programs exclusively; no other customer agencies are represented. All awards are unrestricted (no set-aside designation).

The two most recent task orders, awarded in December 2023 and January 2024, carry ceiling values of $29.8 million and $25.6 million respectively, with completion dates extending to 2028 and 2029. Earlier orders, particularly those issued at vehicle award in March 2021, have largely completed performance, with ultimate completion dates through 2024 and 2025.

The Research Enabling Procurement for Aerospace Systems (REPAS) program will advance the state of the art of propulsion, power and thermal management technologies for transition to the warfighter. Efforts will include component design and development; subsystem integration; and bench, rig and engine testing; of technologies that improve the affordability, manufacturability, digital traceability and capability of existing and future systems. The majority of this program is expected to be performed on-site at various AFRL facilities.
