About this vehicle
The Department of the Air Force Air Education and Training Command established this multiple-award Master IDIQ for comprehensive fleet management, aircraft maintenance, and site-specific mission support services, with ordering authority extending through August 31, 2030. The vehicle carries a shared ceiling of $14 billion and remains actively competed with no set-aside restrictions.
Ordering momentum has been consistent but episodic over the vehicle's five-year history. The portfolio shows 16 task orders awarded since September 2020, with an average of roughly 1.6 orders per year over the most recent five-year period. The combined potential value across all awarded task orders is $2.71 billion, with $1.01 billion obligated to date (37% of potential value), indicating substantial remaining capacity. Recent activity accelerated in 2023 with three orders and continued into 2026 with two orders most recently awarded in February.
Competitive concentration is heavily skewed toward two primes. M1 Support Services, L.P. holds six orders valued at $1.47 billion combined potential, while Amentum Services, Inc. holds five orders valued at $1.24 billion combined potential. These two firms account for 88 percent of task-order count and 100 percent of meaningful contract value. Leidos, Akima Logistics Services, and Dyncorp International each hold single orders with minimal value.
Customer concentration is similarly narrow. Air Education and Training Command dominates with 11 orders valued at $1.48 billion, followed by Air Combat Command with 2 orders at $514 million. Three remaining customers—Materiel Command, Headquarters District Washington, and the Office of the Secretary of Defense—account for one order each. Work spans organizational and intermediate-level aircraft maintenance across multiple platforms (T-38, T-6, A-10, F-15E, F-16, F-22, F-35, KC-46, and VC-25B aircraft) at locations within the contiguous United States, Alaska, and Hawaii. Task-order durations typically range from three to five years, with recent awards ranging from $107.2 million ceiling (T-38 Amplitude contract, awarded February 2026) down to $19.4 million (KC-46 test support). Firm-fixed-price pricing is standard across the portfolio.
