About this vehicle
The Department of the Army Acquisition Support Center PEO Aviation established this Master IDIQ on April 4, 2018, to provide worldwide logistics support services and contractor logistics support (WLSS-C) for non-standard rotary-wing aircraft operated by the Department of Defense, allied countries, and partner nations under the Foreign Military Sales program. The vehicle's ordering period closed on October 11, 2023—nearly two years and nine months ago—making it unavailable for new task orders.
The vehicle is inactive for pursuit purposes. Since the last date to order has passed, no new orders can be placed against this vehicle. The most recent task order was awarded in June 2022. Ordering activity declined sharply after 2019, dropping from 5 orders in 2019 to 2 in 2020, 2 in 2021, and 1 in 2022. The vehicle's combined task-order potential value stands at $701.4 million, with $207.4 million obligated (30% of combined potential).
Task orders fund contractor field service representative support and contractor logistics support for specific allied-nation fleets, including UH-60M Black Hawk helicopters for Afghanistan, CH-47 cargo helicopters for Saudi Arabia, MI-17 and PC-12 aircraft for Afghanistan, and OH-58D helicopters for Greece, as well as support in Kenya, Uganda, Lebanon, and Bosnia and Herzegovina. Pricing terms are predominantly firm fixed price, with some cost-plus-fixed-fee arrangements; durations typically span one to five years.
Work is performed worldwide in CONUS and OCONUS locations depending on customer aircraft and operational requirements. All 18 task orders carry unrestricted, no-set-aside designations. The single customer agency is the Department of the Army. Among eight prime contractors, Arctos Mission Solutions, LLC dominates by potential value at $490.7 million across 2 orders, primarily driven by a single large MI-17/PC-12 sustainment effort. Pinnacle Solutions, LLC holds the second position with 6 orders valued at $165.9 million combined. The remaining primes—Dyncorp International LLC, Black Hall Aerospace, Inc., Leidos, Inc., and three others—collectively account for the balance. Task orders range from minimum guarantees of $2,000 to a high of approximately $490.7 million in combined potential value.
