What Zel Technologies does

Zel Technologies, LLC (ZelTech) is a privately held, small-business U.S. government contractor founded in 1988 and headquartered in Hampton, Virginia, that delivers scientific, engineering, technical, and mission-support services to the Department of Defense and the Intelligence Community. Its functional portfolio spans seven capability lines: Scientific and Technical Services (SETA and hardware/software development), C5ISR and Intelligence Services (ISR collection management, multi-source and all-source analysis, GEOINT/SIGINT/HUMINT/MASINT, cyber threat analysis, F3EA targeting), Modeling and Simulation (including the proprietary ZT-HYDROFLASH™ 2-D hydrodynamic code for nuclear EMP and lightning simulation), Space Systems Integration and Engineering, Ground Combat Training (Z-MILES and the J&F Alliance Group AR/VR JV), Homeland Security and Command & Control, and Solutions Engineering (unmanned systems design, AI/ML vulnerability assessment, and cybersecurity).

The company's underlying technology stack rests on first-principles physics-based simulation, sensor modeling, and cleared operational subject-matter expertise. ZT-HYDROFLASH™ solves coupled fluid and Maxwell equations using Conservation Law algorithms to simulate nuclear detonation EMP at all heights of burst and high-altitude discharges; the modeling group also operates Monte Carlo transport and kinetic Boltzmann electron-transport codes for nuclear detection. Z-MILES delivers open-architecture force-on-force ground combat training across dismounted, vehicle, and instrumentation systems, with 100,000+ training devices delivered over two decades. Sub-brands Tulle and Elite extend the training franchise, and solutions engineering covers maritime, terrestrial, and aerial unmanned-system design plus vulnerability testing.

ZelTech earns revenue almost exclusively through U.S. federal contracting, operating as a prime and subcontractor on multiple award IDIQ vehicles including OASIS-SB Pool 4, OASIS+ unrestricted and small business, and SeaPort-NxG. Recent awards include the Air Force Life Cycle Management Center IDIQ (FA868423DB111) with a $900 million ceiling through December 2032, the single-award Air Force OSEE II contract ($45 million ceiling, base through 2030), and DIA Rapid Prototyping and ST-ATI task orders. Pricing is set by competitive bidding and negotiation on individual task orders and is not publicly disclosed. The customer base is concentrated in the Air Force, DIA, Army Air and Missile Defense Command, DTRA, JTF-CS, and FEMA, with 182 employees (over 70% veterans) operating from Hampton, VA (HQ), Melbourne, FL (OTS), Winter Park, FL (Training Solutions), and Reston, VA. The firm is founder-led (Jack Ezzell, Jr., Executive Chairman; Jay Ezzell, CEO) and holds CMMC Level 2, ISO 9001, SWaM, and Virginia Values Veterans (V3) certifications.
