Invariant Corporation

Invariant Corporation, a Huntsville, Alabama-based for-profit Subchapter S corporation, operates primarily as a subcontractor (78% of recent awards) delivering advanced defense engineering, weapons systems development, and mission-critical technology services to the Department of Defense and allied commands. The vendor competes on a full-and-open basis across all active awards with no set-aside designations, positioning it as a specialized prime on large indefinite delivery vehicles and as a technical subcontractor supporting systems integration, modeling and simulation, sensor development, and missile guidance work under major defense primes.

Invariant's customer footprint concentrates heavily on missile, space, and counter-unmanned aircraft programs within the Defense Department. The Naval Sea Systems Command dominates potential value by a wide margin, anchored by a $4 billion Seaport Next Generation multiple-award IDC awarded January 2, 2025, through January 1, 2029. The Marine Corps accounts for $327.9 million across six awards, driven by a $308.9 million single-award Counter-Unmanned Aircraft System Engagement System contract awarded October 16, 2024, with performance through October 15, 2029. The Army Materiel Command's Aviation and Missile Life Cycle Management Command represents $100 million across 19 awards and is the top customer by award count. The top five funding agencies by potential value (Navy, Marine Corps, Army AMCOM, GSA Federal Acquisition Service, and Army PEO Missiles and Space) account for the full disclosed dollar value, reflecting deep concentration in missile defense and counter-UAS platforms. Recent prime delivery orders exemplify the scope: a $11.3 million firm fixed-price order from PEO Missiles and Space (September 26, 2024) for missile procurement on the Advanced Tactical Integrated Defense system, a $10.4 million cost-plus-fixed-fee order from the Marine Corps (November 20, 2024) for engineering, integration, and test services on the Counter-UAS Engagement System Group 3 First Article Test unit, and a $5.1 million Other Transaction Agreement (awarded April 15, 2026) from US Special Operations Command for the Surface to Air Kinetic Engagement program.

Invariant holds multiple vehicles enabling task-order competition: the GSA Multiple Award Schedule (45 task orders) with a $65 million ceiling through April 28, 2029, offering engineering and technical consulting services under Special Item Numbers 541330ENG, 541380, 541420, and 541715; the One Acquisition Solution for Integrated Services (OASIS) Small Business vehicle (41 task orders) providing access to Army and broader federal customer bases; and three single-award or limited-use indefinite delivery contracts with Naval Sea Systems Command ($4 billion, multiple-award), the Marine Corps ($308.9 million, single-award counter-UAS production), and Army Aviation and Missile Command ($100 million, requirements contract through June 30, 2027). The GSA Schedule labor portfolio spans 28 categories with hourly rates from $39.59 (entry-level administrator, high school education, no clearance) through $242.34 (senior research engineer/scientist, bachelor's degree, 16 years experience, security clearance required), positioning Invariant for both junior technical staffing and senior engineering leadership assignments across federal agencies.

Activity accelerated sharply in 2024, with 82 awards (up from 9 in 2023 and 7 in 2022), driven principally by subcontract task orders under Torch Technologies, Booz Allen Hamilton, Sierra Nevada Company, and other large defense primes. Torch Technologies alone accounts for approximately 70+ of Invariant's sub awards, concentrated on Army Aviation and Missile Center engineering support, modeling and simulation, weapons development analysis, and EOD/unmanned systems technology development. The subcontractor concentration reflects Invariant's role as a technical feeder for systems integrators and major contractors executing complex defense programs. Five awards totaling $22.6 million in combined potential value are due to complete within the next twenty-four months, representing recompete exposure primarily in sub-contract positions with recurring Torch, Booz Allen, and other primes. Service Contract Inventory data shows minimal SCI-reportable invoiced revenue (SCI captures federal service contracts above $150,000 threshold and excludes goods, classified work, and non-federal revenue); the vendor reported roughly 17.7 FTEs across six subcontract engagements in FY2024. Invariant's subcontracting base includes Torch Technologies Inc., Booz Allen Hamilton Inc., and Sierra Nevada Company for prime work, while Invariant itself engages specialized suppliers including The Will-Burt Company (masts and assemblies), Wescam Inc. (electro-optical/infrared imaging), Solar Stik Inc. (power systems), and Viewpoint Systems LLC (displays and mission computers) on its larger Marine Corps and SOCOM delivery orders. The vendor's technical portfolio emphasizes object-oriented software development, systems engineering analysis, simulation and modeling, sensor integration, missile guidance systems, and hardware fabrication—capabilities that position it as a downstream technical contributor to prime contractors executing the Department of Defense's advanced air defense and counter-unmanned aircraft modernization missions.
