Mantech Tsg-2 Joint Venture

Mantech Tsg-2 Joint Venture, a for-profit joint venture headquartered in Herndon, Virginia, delivers defense research and development, systems engineering, and technical analysis services to the Department of Defense as a prime contractor on full-and-open federal defense contracts, with no set-aside posture. The joint venture is a subsidiary of Mantech Advanced Systems International, Inc.

Mantech Tsg-2 competes exclusively in the Defense Department ecosystem, with ten distinct customer agencies represented across 35 prime awards (97% of total awards) carrying $58.7 billion in combined potential value. The Office of the Secretary of Defense dominates the customer base by dollar value—six awards carrying $54.93 billion in combined potential value—while the United States Marine Corps, the Department of the Navy, and the Department of the Air Force Materiel Command anchor the activity count. The Marine Corps issued six awards worth $900.3 million combined; Naval Sea Systems Command placed four awards worth $511.7 million; Naval Air Systems Command placed four awards worth $342.3 million; and Air Force Materiel Command placed seven awards worth $373 million.

Mantech Tsg-2 places virtually all work under the Information Analysis Center Multiple-Award Contract (IAC-MAC), a DoD research and engineering IDIQ. Twenty task orders under IAC-MAC carry $3.37 billion in combined potential value. The vendor also holds twelve task orders on the Defense Systems Technical Area Tasks vehicle worth $435 million combined. Representative prime work includes a $714.987 billion delivery order issued by the Department of the Navy in August 2024 for Marine Corps Force Design and Modernization at the Marine Corps Warfighting Laboratory Futures Directorate, encompassing force design research, unmanned aircraft systems engineering, weapons systems development, electronic warfare, and advanced training support with place of performance in Stafford, Virginia; a $344.6 million delivery order from the Marine Corps in July 2026 for research and development on command, control, communications, intelligence and cyber capabilities for Naval Surface Warfare Center Crane Division; and a $329.8 million delivery order from US Fleet Forces Command in May 2022 for weapons systems and aviation warfare modeling, simulation, engineering, integration, experimentation, and cybersecurity training at Naval Surface Warfare Center, Corona Division, with place of performance in Herndon, Virginia. Additional significant awards include a $197.2 million April 2026 Naval Sea Systems Command delivery order for radar and electronic warfare systems research, development, test, and evaluation at Crane, Indiana; a $204.97 million August 2024 Marine Corps delivery order for intelligence warfare research and development support at Quantico, Virginia; a $150.7 million October 2021 Office of Naval Research delivery order for Force Design 2030 research at Quantico; and a $115.3 million July 2022 Marine Corps delivery order for intelligence systems portfolio research and development at Stafford.

The vendor's capability portfolio centers on defense systems integration, advanced research and development across radar, electronic warfare, unmanned systems, and weapons modernization, with demonstrated strength in naval platform modernization and Marine Corps force design initiatives. Award-derived NAICS distribution shows concentration in research and development in physical, engineering, and life sciences (21 awards) and applied research and exploratory development (13 awards), with PSC codes tracking R&D and applied research and defense-related activities.

Mantech Tsg-2's subcontractor footprint reflects deep integration across defense primes and specialized component suppliers. Recent major subcontractor relationships include Science Applications International Corporation (SAIC) for software engineering and systems integration on the weapons systems modeling and simulation effort; L3Harris Technologies for tactical communications equipment; Slitherine Corporation for military simulation software; Anduril Industries for autonomous systems and counter-UAS capabilities; Palantir USG for platform evaluation and software licenses; and SIG Sauer Inc. for ammunition procurement. Additional subcontractors span specialized aerospace suppliers, communications equipment manufacturers, unmanned systems integrators, and IT infrastructure providers supporting systems engineering across naval and Marine Corps modernization programs.

Activity remains episodic—two awards in 2026, one in 2025, two in 2024, one in 2023, and four in 2022—reflecting the long development and performance cycles of major DoD research contracts. Five awards carrying $550.6 million in combined potential value reach ultimate completion inside the next twenty-four months and face recompete. Obligated dollars total $2.68 billion against the $58.7 billion potential value ceiling, representing 5% execution rate, consistent with early-stage research and development delivery orders.
