Capstone Research Corporation

Capstone Research Corporation, a for-profit Subchapter S corporation headquartered in Huntsville, Alabama, operates predominantly as a subcontractor (94% of awards) on defense systems engineering, modeling and simulation, and program management work, with nascent prime positioning on two large Missile Defense Agency vehicles and a GSA Federal Supply Schedule contract awarded in mid-2026. The vendor competes under full-and-open procurement across both prime and sub channels with no set-aside designations.

Capstone's customer concentration sits with Army missile and simulation programs. The top five customers account for 85% of award count, dominated by the Department of the Army Acquisition Support Center's PEO Missiles and Space (26 awards) and PEO Simulation, Training and Instrumentation (6 awards), the United States Marine Corps (4 awards), the Office of the Secretary of Defense (3 awards), and the Missile Defense Agency (2 awards, $500 combined potential value). The dollar rankings diverge sharply — the GSA Federal Acquisition Service anchors 100% of combined potential value ($92 million) through a single Federal Supply Schedule contract awarded June 30, 2026, with a five-year ceiling of $92 million and ultimate completion date of June 29, 2031. That GSA schedule enables direct ordering across federal agencies for systems engineering, analysis, program management, R&D support, requirements and specifications management, configuration control, information assurance compliance, test and evaluation, and modeling and simulation services, with performance occurring nationwide and internationally as required.

Capstone also holds two prime positions on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program under the Missile Defense Agency. The parent IDIQ, awarded December 29, 2025, carries a $151 billion ceiling through December 28, 2035, structured for classified and unclassified multi-domain defense work spanning systems engineering, R&D, prototyping, test and evaluation, cybersecurity, and modernization leveraging AI, machine learning, digital engineering, and open systems architectures. An initial delivery order, awarded on the same date, carries a $500 ceiling and establishes the vehicle for subsequent task and delivery orders. The SHIELD ceiling is a placeholder system marker for no specified dollar limit; the actual program scope encompasses advanced multi-domain defense against ballistic, hypersonic, and cruise missiles.

Subcontractor activity centers on Torch Technologies Inc. — Capstone subcontracts to Torch on 18 awards across GSA OASIS SB (Pool 5B) task orders for aviation and missile element modeling, simulation, and analysis, and hardware-in-the-loop systems engineering supporting the Army Combat Capabilities Development Command Aviation and Missile Center's S3I Directorate. Named sub primes also include Intrepid LLC (10 SETA support tasks for the Integrated Fires Mission Command Project Office), Alexandria Insights Inc. (3 awards supporting the Marine Corps Expeditionary Radars program), Parsons Government Services Inc. (2 TEAMS-NEXT missile defense systems engineering tasks), Booz Allen Hamilton (2 survivability and lethality analysis and surface warfare support tasks), and others. Activity has grown sharply — three awards in 2023, nineteen in 2024, and twenty-five in 2025 — with one award in 2026 to date. Capstone's sub positioning is concentrated; across SCI-reportable service contracts, the vendor delivered roughly 0.9 FTEs in FY2022 and 2.1 FTEs in FY2024, reflecting light labor intensity relative to the task-order count, consistent with technical and analytical subject-matter expertise roles rather than large staffed program teams. The $32.4 million in obligations (35% of the $92 million combined potential value) reflects early-stage burn on the newly awarded GSA schedule and SHIELD IDIQ.
