Crossflow Technologies Inc.

Crossflow Technologies Inc., a for-profit Subchapter S corporation based in Huntsville, Alabama, operates predominantly as a subcontractor (94% of recent awards) delivering systems engineering, modeling and simulation, weapons development, and technical advisory services to the Department of Defense and related federal agencies, with recent prime seats on multi-billion-dollar indefinite-delivery contracts anchoring its vehicle portfolio.

The company holds prime positions on four major IDICs: the $151 billion Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program with the Missile Defense Agency (awarded December 29, 2025, with ultimate completion December 28, 2035), the $4 billion SeaPort Next Generation contract with Naval Sea Systems Command (awarded January 2, 2025, through January 1, 2029), the $900 million Air Force Life Cycle Management Center Architecture and Integration Directorate IDIQ (awarded June 30, 2023, through November 14, 2027), and the $46 billion Eglin Wide Agile Acquisition Contract (EWAAC) with the Air Force Materiel Command at Eglin Air Force Base (awarded March 14, 2023, through September 9, 2031). All four vehicles carry no set-aside designations and fund full-and-open competition. On the SHIELD vehicle alone, Crossflow received a $500 minimum-guarantee delivery order on December 29, 2025. Representative prime work includes a $149.454 thousand SBIR Phase I contract from an unspecified federal Shared Services Center (awarded September 29, 2025) for a Total Small Business set-aside focused on a comprehensive MBE approach to regulations and standards gap analysis of Advanced Air Mobility platforms, and a $167.542 thousand SBIR Phase I contract from the Air Force Research Laboratory (awarded September 23, 2024) for B-52H digital twin development.

Crossflow's subcontractor footprint is dominated by work under Torch Technologies Inc., which accounts for the vast majority of sub-award activity. Crossflow delivers systems engineering, modeling and simulation support, technical services, specialty engineering, and weapons-development analysis across Army Combat Capabilities Development Command (CCDC) directorates—including the Aviation and Missile Center (AvMC) Software, Simulation, System Engineering and Integration (S3I) Directorate, the Weapons Development and Integration Directorate, and the Systems Readiness Directorate—alongside emerging sub relationships with BAE Systems Technology Solutions & Services Inc. on labor-hour funding for systems engineering (Trident D5LE2 program, awarded September 10, 2024, and other incremental funding actions through July 2024), and with Science Applications International Corporation on system software lifecycle engineering for Army software modernization (awarded June 5, 2025). Sub work spans hardware-in-the-loop simulation, missile modeling and discrimination analysis, Future Vertical Lift (FLRAA) platform systems engineering, counter-UAS technology assessment, and test-and-evaluation support for multi-domain defense systems. Awards carry both GSA OASIS SB (Pool 5B) and direct-task execution authority; recent sub awards cluster in late 2025 and throughout 2024, with dates running back to August 2021 for foundational S3I support.

Customer concentration sits heavily with the Army and Army acquisition support entities. The top five customer agencies or sub-elements account for 74% of recent awards (by count): the Department of the Army (39 awards), the Department of the Army Acquisition Support Center PEO Missiles and Space (38 awards), the Department of the Army Acquisition Support Center PEO Simulation, Training and Instrumentation (25 awards), the Department of the Air Force Materiel Command Lifecycle Management Center Wright Patterson Air Force Base (20 awards), and the Department of the Army Materiel Command Aviation and Missile Life Cycle Management Command (15 awards). By potential value, the concentration is extreme: the Department of the Air Force Materiel Command Lifecycle Management Center Eglin Air Force Base accounts for $46 billion across 2 awards (EWAAC and an associated minimum-guarantee task order), Naval Sea Systems Command for $4 billion across 2 awards (SeaPort-NXG vehicle and minimum-guarantee task order), and the Air Force (aggregated) for $900 million across 2 awards. The Missile Defense Agency's SHIELD vehicle, awarded in December 2025 with a $151 billion ceiling, appears separately in the combined potential value tally. Most sub work flows through Army customer elements, particularly CCDC AvMC and its directorates.

Task order placement against parent vehicles reflects the OASIS SB and GSA MAS concentration. One Acquisition Solution for Integrated Services—Small Business (OASIS SB) hosts 103 task orders, the GSA Multiple Award Schedule (MAS) hosts 52 task orders, the Navy's SeaPort-NXG holds 6 task orders, and other smaller vehicles (Responsive Strategic Sourcing for Services, ASTRO) carry one or a handful each. The tight coupling to OASIS SB and MAS signals Crossflow's small-business posture across subcontractor delivery, though the company does not appear to hold those vehicles as a named prime in the source material.

Activity has grown sharply. Awards per year climbed from 6 in 2021 to 87 in 2024, before stabilizing at 71 in 2025; the source captures only one award in 2026 (dated June 16, 2026, four weeks before the source snapshot date). The recompete cliff is minimal: only one award with an ultimate completion date in the next twenty-four months carries a potential value of $149 thousand. Combined potential value across all 185 awards (prime and sub) sits at $50.9 billion, though obligated dollars amount to only $29 million (a fraction of one percent), reflecting the typical unexercised ceiling nature of IDIC holdings.

The vendor's award footprint skews heavily toward research and development in physical, engineering, and life sciences (108 awards) and engineering services (63 awards), consistent with its CCDC AvMC simulation and weapons-engineering mission. SCI-reported service-contract activity is minimal: the source captures six sub-records spanning FY2022–FY2024, with 0.4 FTEs reported in FY2022 and 3.0 FTEs in FY2024—a reflection of the vendor's niche role as a specialist subcontractor rather than a broad-based service provider. The company maintains active GSA Schedule labor categories spanning engineer/scientist, program analyst, and subject-matter expert roles, with rates running from $65.74/hour (entry-level engineer/scientist) to $247.16/hour (master's-degree SME roles), none requiring security clearance.

Crossflow operates with six named subsidiaries—Photon Flux LLC, Photon Sbflux LLC, Photon Lbflux LLC, Photon Pflux LLC, Photon Eflux LLC, and Photon Aflux LLC—all structured as small-business joint ventures and limited-liability companies, though the source does not enumerate subsidiary-specific contract activity or capability differentiation.
