About Amentum Spaceport LLC
Amentum Spaceport LLC, a subsidiary of PAE Applied Technologies LLC headquartered in Chantilly, Virginia, provides base operations, spaceport services, range operations support, and facilities engineering exclusively as a prime contractor to the Department of the Air Force and the National Aeronautics and Space Administration, competing on an unrestricted, full-and-open basis with no set-aside designations across its 84 recent federal awards.
Amentum Spaceport's capability footprint centers on pre-launch processing, range operations, launch vehicle certification, infrastructure maintenance, and logistics support at Cape Canaveral Space Force Station and Kennedy Space Center. The vendor's work portfolio spans multiple launch platforms including Atlas V, Delta IV, and ULA Vulcan. Representative contracts include a $230,250 firm-fixed-price delivery order from Air Force Space Command in October 2025 for base operations and spaceport services supporting Space Launch Delta 45; a $448,718 delivery order under the BOSS contract (80KSC018C0017) for Contract Year 6 baseline funding; and a $479,470 delivery order from Air Force Space Command in April 2023 for comprehensive base operations and spaceport services across the fiscal year. Amentum Spaceport also performs specialized work including HVAC replacement on the Multiple Object Tracking System ($47,340 in March 2026) and certification support for ULA Vulcan ($2,904 in October 2024).
Customer concentration is extreme and asymmetric. By award count, the Space and Missile Systems Center dominates with 45 orders (100% of the vendor's award count coverage), followed by Air Force Space Command with 31 orders and NASA Kennedy Space Center with 3 orders. However, NASA Kennedy Space Center anchors 99.5% of combined potential value at $722.4 million across those three awards — a stark divergence from the volume ranking. The Air Force Space Command and Space and Missile Systems Center collectively account for $4.3 million in 81 task orders, most under $100,000. This customer split reflects Amentum Spaceport's dual role: a high-volume tactical vendor for day-to-day Air Force range operations and a strategic partner on NASA's large infrastructure programs.
Amentum Spaceport operates exclusively under a single parent vehicle: Indefinite Delivery Contract 80KSC019D0014, a multi-year IDIQ through which 81 of 84 recent awards have flowed as delivery orders. The three NASA awards sit outside this vehicle. The vehicle carries a combined potential value of $4.4 million across 81 task orders, indicating small average order sizes ($54 thousand) — consistent with the micro-transaction profile of Air Force range support work.
The vendor faces acute recompete exposure in the next twenty-four months. Three awards with ultimate completion dates through July 2027 carry combined potential value of $719.7 million — essentially all tied up in the NASA Kennedy Space Center awards. The first two NASA deliverables complete by the end of FY2026 and FY2027, and a single Air Force Space Command award completes by July 2026. Loss or delay of NASA renewal would represent an existential business event for the subsidiary.
SCI-reported invoicing across three prime contracts shows stable federal services revenue of $267.6 million across FY2022–FY2024 ($89.7 million, $91.9 million, and $86 million respectively), with reported FTE delivery growing from 492 to 559 across those years. On federal services contracts captured in SCI, median government-paid rates run around $75/hr, with senior labor pricing through $85/hr and junior positions at $70/hr. Across SCI-reportable prime contracts, subcontractors account for 6% of total contractor hours, with four named subcontractors reported — indicating Amentum Spaceport builds most delivery internally. The vendor operates as a pure prime: all 84 recent awards are prime contracts, with no sub-award footprint in the source data.
