About the company
Integrated Solutions For Systems, Inc., doing business as Is4S and headquartered in Huntsville, Alabama, is a for-profit small business manufacturer and systems integrator that delivers advanced engineering, software development, weapons systems integration, and defense research and development to the Department of Defense as a prime contractor (82% of recent awards) and as a subcontractor to major defense primes. Is4S competes predominantly under full-and-open vehicles and unrestricted task orders rather than set-asides, though the vendor carries a significant portfolio of small business set-aside SBIR and STTR awards across multiple DoD agencies.
Is4S's customer concentration centers on the Department of the Air Force, which accounts for 84% of combined potential value across recent awards. The Air Force Materiel Command Research Laboratory leads by award count (52 awards, $91.4 million potential value), followed by the Air Force (20 awards, $46.08 billion potential value), driven primarily by two high-ceiling indefinite delivery vehicles: the $46 billion Eglin Wide Agile Acquisition Contract (EWAAC) and the $151 billion Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) IDIQ awarded by the Missile Defense Agency in December 2025. Remaining customer concentration includes the Army Materiel Command Research Development and Engineering Command (29 awards, $86.4 million potential value) and the Air Force Lifecycle Management Center at Eglin AFB (13 awards, $572.9 million potential value), together covering 54% of awards by count.
Representative prime work includes a $205.1 million delivery order under EWAAC for Long Range Stand Off B-52H carriage equipment pre-production and production (awarded December 2025, ultimate completion September 2026), a $70.2 million definitive contract with AFLCMC Eglin AFB for Common Munitions Software Defined Radio prototype development under small business set-aside (awarded December 2023, cost-plus-fixed-fee, completion February 2027), a $27.3 million Army Research, Development and Engineering Command contract for plug-and-play open architectures for positioning, navigation, and timing under small business set-aside (awarded January 2022, cost-plus-fixed-fee, completion June 2027), and a $9.915 million Air Force Research Laboratory contract for an Electronic Warfare Situational Awareness Toolkit without set-aside (awarded February 2026, cost-plus-fixed-fee, completion May 2031). Is4S also carries prolific SBIR and STTR activity across Air Force Research Laboratory, Naval Sea Systems Command, Army Research Development and Engineering Command, and Missile Defense Agency, with Phase I through Phase III efforts in directed energy weapons, GPS and positioning technologies, munitions development, autonomous systems, and software-defined radio.
Is4S holds three major indefinite delivery vehicles: the SHIELD multiple-award IDIQ with the Missile Defense Agency ($151 billion ceiling, 10-year term through December 2035, awarded December 2025); the OASIS+ Total Small Business Set-Aside IDIQ through GSA (multi-billion-dollar ceiling, five-year base through December 2029, awarded December 2024); and the OASIS+ Unrestricted IDIQ through GSA (multi-billion-dollar ceiling, five-year base through December 2029, awarded December 2024). Is4S also holds single-award IDCs with Army Research, Development and Engineering Command for positioning, navigation, and timing R&D ($9.49 million, through March 2026) and with the Air Force for model design and strategic planning ($9.95 million, through January 2029).
Activity has grown substantially year over year—25 awards in 2022 to 43 in 2024—though 2025 and 2026 data in the source reflect partial-year capture. Twenty-one awards with combined potential value of $184.6 million reach ultimate completion inside the next twenty-four months and face recompete exposure. In the subcontractor role, Is4S delivers weapons systems engineering, munitions science and technology, positioning and navigation systems, and tactical network support to major primes including Torch Technologies (repeated awards for weapons development and integration support), HII Mission Technologies (munitions science and technology R&D), Janus Research Group (tactical network portfolio support), Lockheed Martin (positioning, navigation, and timing systems for foreign military sales), Rockwell Collins (Mounted Assured Positioning Navigation and Timing System Gen II), and Parsons Government Services (missile defense systems engineering and Japan Aerospace Defense Ground Environment support).
Is4S's capability portfolio centers on weapons systems design and integration, advanced munitions development, directed energy and autonomous systems, positioning and navigation technologies, software-defined radio and communications modernization, systems engineering and digital engineering, test and evaluation, and model-based systems engineering. The vendor's GSA Schedule carries 76 active labor categories spanning $24.61/hr co-op roles through $396.11/hr subject-matter expert positions, with no security-clearance-required offerings and education requirements from high school through master's degree; this portfolio supports the vendor's role executing professional services task orders under OASIS+ vehicles. The vendor executes work across Huntsville, Alabama (primary); Auburn, Alabama; Niceville, Florida; Trotwood, Ohio; and subordinate classified program locations across the continental United States and hostile areas as required by individual delivery orders.
The SCI dataset shows minimal service-contract activity: $300 thousand in SCI-reportable invoiced revenue (FY2022–FY2025, prime records only), reflecting the vendor's orientation toward goods, R&D contracts, and OTA work that fall outside the $150,000 SCI reporting threshold. Is4S operates primarily as a prime on its own engineering and manufacturing delivery teams, with subcontractor engagement reserved for specialized suppliers (Jama Software for requirements management, BAE Systems for hardware design, academic institutions for research support, and component manufacturers) rather than staff-augmentation or time-and-materials sub engagement. The vendor's subcontractor footprint under major defense primes spans weapons integration, munitions development, advanced sensors, and tactical network support, positioning Is4S as a trusted delivery partner for next-generation defense capability development across the Air Force and Army acquisition landscape.
