About Sphinx Defense Inc.
Sphinx Defense Inc., an Arlington, Virginia-based defense contractor, holds a $151 billion multiple-award IDIQ contract (Scalable Homeland Innovative Enterprise Layered Defense, or SHIELD) with the Missile Defense Agency under full-and-open competition, and operates primarily as a subcontractor (75% of recent awards) to defense primes on satellite command-and-control and fire control systems work. The SHIELD IDIQ, awarded December 29, 2025, carries a performance period through December 28, 2035, and enables rapid task order issuance for multi-domain defense systems spanning air, missile, space, cyber, and hybrid threat detection, tracking, interception, and neutralization across all phases of flight, including ballistic, hypersonic, and cruise missiles.
Sphinx's recent footprint reflects minimal current revenue against enormous vehicle capacity. Total awarded potential value across all eight awards stands at $500 (the initial SHIELD delivery-order ceiling), yet combined dollars obligated total $5.5 million — a signal that the $500 valuation reflects a baseline initial order with obligated spend driven by subcontract work on mature programs rather than new SHIELD task order volume. The vendor serves four customer agencies: the Navy's Office of Naval Research (four awards, all subcontract orders on IDC N0017321D2001), the Missile Defense Agency (two awards, $500 combined potential value), the Air Force (one award), and United States Special Operations Command (one award). All eight recent awards fall within NAICS 541712 (Research and Development in Physical, Engineering, and Life Sciences) or 541512 (Computer Systems Design Services), positioning the firm as a defense R&D and systems-engineering contractor.
Sphinx subcontracts to Asrc Federal System Solutions LLC on three satellite and ground command-and-control task orders (awarded August 2025, May 2025, and March 2025), to Booz Allen Hamilton on an October 2024 EMAPS 2 software-development sub task, and to Kratos Technology & Training Solutions on a March 2025 Advanced Fire Control Ground Infrastructure engineering sub task. The Navy represents the largest customer by order count (four subcontract positions on the N0017321D2001 IDC vehicle), while the Missile Defense Agency SHIELD win represents the highest-ceiling vehicle and the only prime IDIQ position. Sphinx holds one task order seat on Alliant II. Activity has accelerated from two awards in 2024 to six in 2025, driven entirely by subcontract orders on existing Navy and SOCOM programs and the SHIELD IDIQ award itself.
