About HX5 LLC
HX5 LLC, a Fort Walton Beach, Florida-based certified women-owned small business, provides aerospace engineering, research and development, and multidisciplinary technical support services to civilian and defense federal agencies as a prime contractor on nearly all of its recent work (96% of awards). HX5 holds SBA certifications as a women-owned small business, service-disabled veteran-owned small business, veteran-owned business, minority-owned business, and Hispanic American-owned business, and competes across both set-aside categories (Total Small Business, WOSB, SDVOSB) and full-and-open federal acquisitions.
HX5's capability footprint centers on aircraft propulsion research, advanced power systems development, thermal management analysis, specialized hardware design and fabrication, software development, cybersecurity research, and program management and administrative support. Concrete recent prime work includes a $1.89 million GEARS (Glenn Engineering and Research Support) task order with NASA Glenn for intern program support (awarded April 2026, set-aside Total Small Business), a $4.95 million GEARS delivery order for intern administration at Langley Research Center (awarded January 2026, Total Small Business set-aside), a $41.6 million OASIS+ delivery order for Engineering, Professional, and Administrative Support Services (EPASS) to the Air Force Materiel Command's Armament Division at Eglin Air Force Base (awarded September 2025, Total Small Business set-aside), and a $37.9 million OASIS+ delivery order for munitions sustainment EPASS to the Air Force Life Cycle Management Center at Hill Air Force Base (awarded September 2024, Total Small Business set-aside).
Customer concentration is split between civilian space research and Army cyber/R&D work. The top five funding agencies account for 82% of award count: the Army Corps of Engineers Engineer Research and Development Center (147 awards, $341 million combined potential value), NASA Glenn Research Center (76 awards, $544.6 million combined potential value), the Army Corps of Engineers Engineering District Vicksburg (29 awards, $9.5 million), the Air Force Materiel Command Research Laboratory (17 awards, $11.5 million), and the Air Force Air Education and Training Command (12 awards, $3.9 million). By potential value, the ranking shifts: NASA Glenn dominates at $544.6 million across 76 awards, followed by the Army Corps of Engineers ERDC at $341 million across 147 awards, and the Air Force Materiel Command Aeronautical Systems Center at $123.2 million across just 3 awards. This divergence reflects NASA's larger per-order average and the Army's higher order volume.
HX5 holds four active OASIS+ multiple-award IDIQs through GSA's Federal Acquisition Service with multi-billion-dollar ceilings through 2029: the OASIS+ Total Small Business set-aside ($999.999 trillion ceiling), OASIS+ Unrestricted ($999.999 trillion ceiling), OASIS+ Women-Owned Small Business ($999.999 trillion ceiling), and OASIS+ Service-Disabled Veteran-Owned Small Business ($999.999 trillion ceiling). HX5 also seats on the GEARS single-award IDIQ with NASA Glenn ($430 million through 2027), and on December 29, 2025, was awarded a position on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ issued by the Missile Defense Agency ($151 billion through December 28, 2035, no set-aside). Against the GEARS IDIQ alone, HX5 has placed 74 task orders worth $83.2 million combined potential value. Recent task-order activity across OASIS+ vehicles has driven $729.9 million in combined potential value from 19 delivery orders.
Activity has been volatile year over year, declining from 20 awards in 2022 to 9 in 2023, then recovering to 15 in 2024 and 14 in 2025, with 15 awards already issued in the first part of 2026. Across the portfolio, 35 awards with combined potential value of $77.6 million face ultimate completion inside the next twenty-four months, creating moderate recompete exposure.
SCI-reported invoiced revenue (federal service contracts above $150,000) totaled $255.9 million across FY2022–FY2024, with $94.8 million in FY2022, $99.9 million in FY2023, and $61.2 million in FY2024. These figures represent only the subset of HX5's federal work captured in SCI reporting and exclude goods, micro-purchases, and non-federal revenue. Estimated federal-services workforce under SCI-reportable prime contracts was 739 FTEs in FY2022, declined to 381 FTEs in FY2023, and recovered to 480 FTEs in FY2024. Government-paid hourly rates on prime contracts ran a median of $145.92/hr, with 10th percentile labor priced around $81.17/hr and senior-level work commanding rates through $906.65/hr. Across SCI-reportable prime contracts, subcontractors performed approximately 9% of contractor hours, with 145 named subcontractors engaged across the portfolio.
HX5 subcontracts to larger primes on defense and specialized research initiatives: named sub-award primes include Amentum Technology, Inc. (missile defense baseline integrity and events support under the IRES contract), Teledyne Brown Engineering, Inc. (Marshall Operations Systems Services and Integration II engineering), CQ JV, LLC (technical management advisory services for Air Force test centers and aerodynamic validation at Wright-Patterson AFB), Applied Research Solutions, Inc. (engineering support for HN Directorate A&AS and R&D), and Colsa Corp (SCAT 1 EPASS labor for aircraft research and lifecycle management). HX5's sub-engagement reflects selective teaming on large-dollar primes rather than a reliance on sub-award volume.
HX5 also operates HX5 Sierra LLC as a named subsidiary, listed as a for-profit limited liability company.
