Amentum Technology, Inc.

Amentum Technology, Inc., a subsidiary of Amentum Holdings LLC headquartered in Tullahoma, Tennessee, operates as a prime contractor on large defense and space infrastructure contracts, delivering IT infrastructure, cybersecurity, command and control systems, facility management, and space operations sustainment to the Department of Defense and NASA without SBA set-aside designations.

Amentum Technology's customer concentration is extreme: the Missile Defense Agency accounts for 56 of 62 awards (90% of the portfolio) and $7.78 billion of the $15.47 billion combined potential value. NASA Johnson Space Center and Kennedy Space Center together hold two awards each, representing the second and third customer slots with $4.29 billion and $3.41 billion potential value respectively; the Office of the Secretary of Defense holds one $2.7 million award. This concentration in MDA work is reinforced by the recompete cliff: 13 awards (combined potential value $837.6 million) reach ultimate completion within the next twenty-four months, of which the vast majority are MDA orders expiring February 8, 2027.

Amentum Technology's MDA footprint spans over $950 million in awarded delivery orders across multiple mission areas. The vendor holds a single-award indefinite-delivery contract with the Missile Defense Agency for the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program, valued at $151 billion through December 2035, with an initial five-hundred-dollar delivery order placed December 29, 2025. Against a separate MDA vehicle (IDV HQ079617D0001), Amentum has placed 54 task orders worth $3.18 billion combined potential value. Representative MDA work includes a $226.9 million cost-plus-incentive delivery order (awarded August 9, 2025, completing February 8, 2027) for IT services, resources administration, acquisition, management, operations, and cyber defense supporting the MDA Chief Information Officer mission at Schriever Space Force Base; a $108 million cost-plus-incentive order (awarded August 21, 2023, completing December 31, 2026) for classified and unclassified network infrastructure design and implementation, computer network defense, information assurance, service desk portal services, and IT implementation for two-letter project requests; a $87.4 million cost-plus-incentive order (awarded April 1, 2024, completing February 8, 2027) for command, control, battle management, and communications (C2BMC) infrastructure engineering and mission operations; a $68.8 million cost-plus-incentive order (awarded December 9, 2024, completing February 7, 2027) to sustain the Missile Defense System Experimentation Space Operations Center and support research and development of experimental missile defense system space capabilities; and a $60.1 million firm-fixed-price order (awarded July 1, 2024, completing February 8, 2027) for near-real-time cyber detect capability and enterprise cybersecurity system management.

Outside MDA, Amentum Technology holds two single-award indefinite-delivery contracts with NASA. Johnson Space Center awarded a $3.889 billion contract (awarded August 1, 2022, completing September 30, 2027, under NAICS 541715) for engineering and scientific products and technical services to the Engineering and Exploration Integration and Science Directorates, supporting the Space Launch System, Orion Multi-Purpose Crew Vehicle, planetary missions research, and astromaterial curation operations. Kennedy Space Center awarded a $3.406 billion COMET (Consolidated Operations, Maintenance, Engineering, and Test) contract (awarded May 1, 2023, completing September 30, 2026, under NAICS 541715) for ground operations, spacecraft processing, engineering, flight processing, launch and recovery operations, and design support for the Exploration Upper Stage Vertical Stand, supporting the Space Launch System, Orion, International Space Station, and Launch Services Program. A $529,214 phase-in purchase order was issued under the COMET contract on March 1, 2023.

Amentum Technology engages an extensive subcontractor network on its MDA portfolio, including major technology vendors (Dell Federal Systems, Cisco, Microsoft, Amazon Web Services, General Dynamics, World Wide Technology) and small business partners designated as woman-owned small businesses (Sf&B Inc., Black Rock Technology Group LLC, Logistics365 Inc.), service-disabled veteran-owned (Epoch Concepts LLC, Colossal Contracting LLC), and economically disadvantaged women-owned (American Wordata Inc.). Named subcontractors on specific orders include SHI International Corp, Emergent LLC, IT1 Source LLC, Mainline Information Systems LLC, DS Government Solutions Corp, DLT Solutions LLC, One Technology Corporation, Everfox LLC, Immixtechnology Inc., Deltek Inc., Spud TECH LLC, Sirius Federal LLC, and Innovim Defense Services LLC. The Service Contract Inventory dataset shows Amentum Technology as a named subcontractor in three records (FY2022: 57.9 FTEs; FY2024: 32.9 FTEs) with no SCI-reportable invoiced revenue as prime; this reflects the fact that SCI captures only unclassified service contracts above the $150,000 threshold and excludes the bulk of Amentum's MDA classified work.

Activity has declined from seven awards in 2022 and nine in 2023 to four in each of 2024 and 2025, with one award to date in 2026. The portfolio is dominated by cost-plus-incentive and firm-fixed-price delivery orders under the MDA SUPPORT program and related MDA acquisition vehicles, with all awards issued without set-aside designations. Primary work performance locations are Schriever Space Force Base and Colorado Springs, Colorado for MDA work, and Kennedy Space Center and Johnson Space Center for NASA work. The vendor operates as a prime on 61 of 62 total awards (98%), with a single sub-award on record.
