About this vehicle
GSA Federal Acquisition Service awarded Alliant II, a multiple-award IDIQ GWAC for IT services and IT services-based solutions to federal civilian agencies and DOD, on July 1, 2018, with ordering authority extending through June 30, 2028 (approximately 23 months remaining). The vehicle carries a combined task-order potential value of $95.34 billion, of which $46.84 billion (49 percent) has been obligated across 825 task orders.
Alliant II succeeds the original Alliant GWAC (awarded March 2009) and serves 159 distinct customer agencies. Recent task-order velocity has declined: the vehicle averaged 110–112 orders annually in 2022–2023, dropped to 93 in 2024 and 81 in 2025, and shows only 34 awards so far in 2026. The most recent task-order award occurred August 1, 2026.
Competition concentrates heavily among five large primes. Booz Allen Hamilton leads with 133 orders totaling $17.67 billion in combined potential value, followed by General Dynamics Information Technology (68 orders, $12.93 billion) and CACI Federal (46 orders, $11.31 billion). These three firms alone hold 58 percent of the vehicle's combined potential value, while the top five primes (adding Deloitte and SAIC) account for 48 percent of all task orders. The remaining 45 awardees occupy a long tail.
Customer concentration is likewise steep. The Internal Revenue Service and Centers for Disease Control and Prevention together account for roughly one-third of all task orders by count. Treasury, HHS, DHS (TSA, CISA, CBP), and DOD (Air Force, Navy, Army, Marine Corps, SOCOM, Strategic Command, and AFSOC) dominate ordering patterns. No set-aside restrictions apply; all 825 task orders were awarded unrestricted.
Task-order economics span a wide range. Recent mega-orders include a $2.527 billion EMAPS 3 award (Cost Plus Fixed Fee), a $1.418 billion CASTLE-NET award (Cost Plus Award Fee), a $1.479 billion SCITLS order (Cost Plus Award Fee), and a $1.179 billion AFRL Shadow Raptor order (Cost Plus Award Fee). Smaller orders cluster in the $2–40 million range, with pricing structures including Firm Fixed Price, Labor Hours, Time and Materials, and Cost-Plus variants. Delivery periods typically span 2–5 years, though some extend to 2030 or beyond.
Description
The Alliant 2 GWAC is a multiple-award, indefinite-delivery, indefinite-quantity (MA/IDIQ) GWAC that will enable federal civilian agencies and the DOD to provide Information Technology (IT) services and IT services-based solutions from the most qualified businesses.
