Mantech SRS Technologies, Inc.

Mantech SRS Technologies, Inc., a large for-profit subsidiary of publicly traded Mantech International Corporation headquartered in Herndon, Virginia, operates as a prime contractor delivering environmental planning, range sustainability services, systems engineering, and technical support to the Department of Defense and federal civilian agencies on a full-and-open basis without set-aside designations. The company competes across multiple indefinite delivery vehicles and task order vehicles issued by Naval Facilities Engineering Command, the Space and Missile Systems Center, and other DoD components, with a demonstrated portfolio spanning environmental impact assessments, range operations, geospatial services, and program management across domestic and overseas locations.

Mantech SRS Technologies' customer base concentrates heavily on Navy and Marine Corps missions. The Department of the Navy accounts for the largest share of awards by count (470 awards), while the Defense Advanced Research Projects Agency anchors dollar volume through a $1.01 billion combined potential value across 207 awards. Within the Navy, Naval Facilities Engineering Command (NAVFAC) and the Naval Information Warfare Systems Command represent the two largest dollar concentrations, with $293.1 million and $317.4 million respectively in combined potential value. The top five funding agencies account for 67 percent of award count. The company also holds work with the Department of Homeland Security Science and Technology Directorate (16 awards, $784.8 million combined potential value) and GSA Federal Acquisition Service (17 awards, $1.11 billion combined potential value). Representative prime work includes a $264.2 million Systems Engineering & Integration-2 definitive contract with the Space and Missile Systems Center for National Security Space Launch program support (FY2022–FY2024 invoicing: $43 million, $49.4 million, and $54.3 million respectively across 63.5 to 220 FTEs); a $10.065 million GSA Multiple Award Schedule delivery order from the Defense Counterintelligence and Security Agency for Wake Island fuel storage and mooring environmental impact statement preparation; a $12.985 million NAVFAC delivery order for Western Training Area desert tortoise translocation at Fort Irwin; and a $3.8 million NAVFAC delivery order for Northwest Training and Testing Phase IV SEIS/OEIS environmental work.

Mantech SRS Technologies operates predominantly as a prime contractor across its 2,709 awards in the source data (100 percent prime split). The company sits on multiple parent vehicles and issue task orders through them: Indefinite Delivery Contract N0012386D0314 carries 147 task orders; IDC N6274214D1863 carries 113 task orders ($69.1 million combined potential value); and IDC FA461006A0002 carries 109 task orders ($6.7 million combined potential value). The company also participates in DARPA's $1.25 billion Technical and Analytical Support Services II multiple-award IDIQ and NAVFAC's $100 million single-award AE Range Sustainability Services contract. Awards per year have remained stable at 15 to 24 annual awards over the past five fiscal years, with 39 awards (combined potential value $137.2 million) facing ultimate completion within the next twenty-four months and therefore subject to recompete.

SCI-reported invoiced labor on federal service contracts above the $150,000 threshold totaled $203.6 million across FY2022–FY2024: $58.1 million in FY2022, $75.4 million in FY2023, and $70 million in FY2024. The workforce supporting these contracts scaled from 103 FTEs in FY2022 to 253 FTEs in FY2023 and remained at roughly 255 FTEs in FY2024. Government-paid hourly rates on prime contracts ran a median of $132.70 per hour, with senior labor and technical roles commanding rates through $320.79 per hour at the 90th percentile. Across SCI-reportable prime contracts, the company engaged subcontractors for approximately 10 percent of contractor hours, drawing on a roster of 52 named subcontractors; named subs include woman-owned and veteran-owned small businesses such as M.s. Hatch Consulting (air quality analysis), International Archaeology LLC (cultural resource management), Vernadero Group Inc. (environmental consulting), and Western Biological LLC (environmental services), reflecting a pattern of small-business subcontracting on environmental and technical components of larger prime work.

Mantech SRS Technologies' capability portfolio spans environmental compliance and impact assessment, range complex management and sustainment, systems engineering and technical integration, geospatial information services, and program management support. NAICS concentration reflects this mix: Engineering Services (279 awards), Environmental Consulting Services (148 awards), and Facilities Support Services (110 awards) represent the top three categories. The company delivers work at domestic installations, overseas locations including Japan, Guam, and the Pacific region, and on national security space launch platforms. Corporate structure shows Mantech SRS Technologies as a direct subsidiary of Mantech International Corporation, with a Mantech-Aecom Joint Venture named as a secondary subsidiary entity. The parent company's broader indefinite delivery vehicle portfolio and established relationships with NAVFAC, DARPA, Space and Missile Systems Center, and other major federal customers position the subsidiary to compete across a diverse array of environmental, technical, and systems engineering missions supporting military training, testing, and space operations.
