About Amentum Services, Inc.

Written by GovTribe AI ·

Amentum Services, Inc., doing business as AECOM, is a major federal prime contractor delivering base operations, facility maintenance, aviation and maritime support, systems engineering, and specialized technical services to defense, civilian, and space agencies on a full-and-open (non-set-aside) basis, with 97% of recent awards as prime contracts across a $757.46 billion combined potential value portfolio. The company is a for-profit organization headquartered in Chantilly, Virginia, operating as a subsidiary of Amentum Government Services Holdings Sub LLC, a parent company with 15 named subsidiaries including Pacific Architects & Engineers LLC, Dyncorp International LLC, and URS Federal Services International Inc., with a broader enterprise spanning international and commercial sectors beyond federal contracting.

Amentum's federal capability footprint centers on four concrete service lines: base operations and facility maintenance support (including housekeeping, utilities management, and grounds operations at forward-deployed military installations); aviation and maritime maintenance (organizational and depot-level support for the MQ-9 Reaper, F/A-18 Super Hornet, MV-22 Osprey, and submarine platforms); systems engineering and technical assistance (C5I test and evaluation, software engineering, and program management); and propellant and life support services for space launch operations. Recent prime awards exemplify this mix: a $452.86 billion definitive contract (awarded March 13, 2026) to provide detention, transportation, and medical services at the Camp East Montana Temporary Detention Center in El Paso, Texas, through ICE; a $485.57 million cost-plus-award-fee delivery order (awarded April 8, 2025) for agricultural cleaning and African swine fever sanitization operations in Germany under the ASTRO GWAC; a $237.07 million cost-plus-fixed-fee delivery order (awarded July 16, 2025) for systems engineering and technical assistance to PEO Soldier under the Responsive Strategic Sourcing for Services (RS3) vehicle; and a $99.68 million cost-plus-fixed-fee order (awarded June 26, 2025) for submarine C5I test and evaluation, engineering, and logistics support to Naval Sea Systems Command.

Amentum's customer base concentrates heavily in Navy programs. The top five funding agencies by award count and potential value cover 44% and 30% of recent awards respectively: Naval Sea Systems Command leads with 709 awards ($25.68 billion combined potential value), followed by Army Materiel Command (51 awards, $78.28 billion), Naval Supply Systems Command (112 awards, $67.78 billion), Naval Air Systems Command (75 awards, $41.97 billion), and the U.S. Coast Guard (157 awards, $11.25 billion). This concentration reflects Amentum's strategic positioning as a primary provider of shipboard maintenance, naval facilities engineering, and forward-deployed base operations across the Navy enterprise. Civilian agencies including NASA Kennedy Space Center (152 awards, $3.43 billion), the Department of State (for GLOBALCAP and diplomatic communications support), and the Transportation Security Administration complete the active customer set, but naval and defense missions dominate dollar value.

Amentum holds a substantial indefinite delivery vehicle (IDV) portfolio totaling more than $67.4 billion in accessible ceiling value across core government vehicles. Major vehicles include: the Worldwide Expeditionary Multiple Award Contract (WEXMAC) 2.2 TITUS ($67.4 billion, Naval Supply Systems Command, through December 31, 2029) for base operations and life support; the OASIS+ Unrestricted contract (reported in portfolio as no ceiling specified in source documentation, General Services Administration, through December 2029) supporting civilian and defense agencies across multiple mission areas; GLOBALCAP ($5 billion, Department of State, through June 30, 2035) for training, equipment, and construction supporting foreign policy and partner nation security; a $995 million single-award contract with Air Combat Command (through September 29, 2030) for MQ-9 Reaper organizational-level maintenance worldwide; Seaport Next Generation (Seaport-NXG) participation for naval engineering and technical services; and specialized vehicles including the DARPA Technical and Analytical Support Services II (TASS II) and Cooperative Threat Reduction Integrating Contract IV ($3.5 billion, Defense Threat Reduction Agency, through August 20, 2035). The company also holds single-award contracts with NASA Ames Research Center ($15 million through March 2030), the Defense Information Systems Agency ($151.57 million for Z Series Chipset processor capacity services through September 30, 2035), and various regional military installation support vehicles. Task order activity against these vehicles is substantial: the Multiple Award Schedule alone shows 233 task orders valued at $595.5 million; the WEXMAC family shows consistent multi-hundred-million-dollar annual obligation patterns; and Kennedy Space Center KPLSS II orders regularly deliver $20–30 million annually.

Activity trajectory from Amentum's award footprint shows steady growth: 153 awards in 2022, 202 awards in 2023, 202 in 2024, 206 in 2025 (through July 15, 2026 reporting date), with 51 awards recorded in early 2026 (partial year). The recompete cliff reveals 140 awards with ultimate completion within the next twenty-four months carrying $11.72 billion in combined potential value—a significant volume of work exposed to competitive recompete, particularly across naval maintenance, facility operations, and Army construction security contracts scheduled to expire through mid-2027.

On federal service contracts captured in the Service Contract Inventory (SCI), Amentum reported $4.48 billion in invoiced revenue across FY2022–FY2024 (prime records only), split $932.1 million (FY2022), $1.8 billion (FY2023), and $1.75 billion (FY2024), representing a subset of total federal service contract revenue and excluding goods, classified work, and non-federal activity. SCI-reported full-time equivalent (FTE) counts show 5,205 FTEs in FY2022 (81 prime records), 12,700 FTEs in FY2023 (127 prime records), and 8,173 FTEs in FY2024 (137 prime records), indicating substantial workforce scaling and variability tied to task order volume and timing of large program executions. Government-paid hourly rates across SCI prime contracts span from a 10th percentile of $26.10/hr (entry-level support roles) through a median of $71.96/hr to a 90th percentile of $184.00/hr (senior technical and management positions). Across SCI-reportable prime contracts, Amentum subcontracts an average of 12% of contractor hours to 366 named subcontractors, indicating a predominantly Amentum-delivered model with selective use of subs for specialized skills, logistics, or regional support. Named subcontractors include Peraton Inc., Booz Allen Hamilton Inc., ManTech Advanced Systems International Inc., HII Fleet Support Group LLC, ECS Federal LLC, and regional vendors such as Subic Drydock Corporation (a minority- and woman-owned business providing shipyard services in the Philippines) and Kuwait Resources House (providing local logistics and sponsorship services in the Middle East).

On the GSA Schedule, Amentum maintains 373 active labor categories with hourly rates ranging from $30.22 (Data Entry Technician, high school education) to $485.73 (Subject Matter Expert 4, bachelor's degree with 6 years experience), covering engineering, program analysis, information systems security, tool room operations, and technical consulting roles with no security clearance requirement noted in the labor portfolio. This spread reflects Amentum's positioning as a provider of both entry-level support and senior technical expertise, enabling flexible task-order staffing across civilian agency and defense facility missions.

Teaming posture shows Amentum operates predominantly as a prime contractor: 97% of awards in the portfolio are primes, with subcontracting concentrated on specific large programs (naval maintenance, Army engineering) where specialized expertise or regional presence is critical. The vendor is not characterized as a feeder subcontractor to other primes; rather, Amentum brings subs into its delivery model as needed to supplement internal capacity or provide local/specialized support. Major prime relationships with other contractors are minimal in the source data, indicating Amentum competes independently for federal work rather than as a named sub on other primes' vehicles.

Set-aside posture is notably full-and-open: across the entire award portfolio, no single set-aside category (8(a), HUBZone, SDVOSB, WOSB) recurs characteristically in the source material. All sampled delivery orders and contract awards are marked "No Set-Aside Used," indicating Amentum competes in unrestricted federal procurements where it faces competition from the full contractor universe. This positioning aligns with the company's large size, substantial IDV presence, and strategic role as a prime contractor on mega-vehicles like OASIS+, WEXMAC, and GLOBALCAP, which are full-and-open vehicles by design.
