What Fisica does

Fisica Applied Technologies, Inc. is a privately held U.S. defense products manufacturer that designs and manufactures airborne antennas, ground-based antennas, electromagnetic systems and simulators, and ruggedized batteries for military and aerospace applications. Operating through four business units — ATI (flash X-ray, electron beam sterilization, and high-power pulse systems for defense, energy, and medical applications); Randtron (ruggedized military airborne antennas for radar, electronic warfare, and communications/navigation/identification); Datron (precision pointing and tracking antenna systems, communications-on-the-move terminals, and transportable SATCOM systems); and Space Vector (high-reliability hardware, batteries, avionics, GPS tracking units, and RF components for launch vehicles, LEO satellites, missiles, and defense systems, acquired in April 2025) — the company maintains a vertically integrated portfolio from core RF and electromagnetic components through flight-critical subsystems. Underlying technology spans flash X-ray pulsers up to 2,300 kV (claimed as the largest commercially available), low-profile WGS-certified Ka-band COTM antennas, 13m–22m full-motion tracking antennas, RCC 319/324-compliant flight termination system batteries, and AS9100/ISO 9001-certified manufacturing.

The company's primary customers are the U.S. Department of Defense (U.S. Space Force, Air Force, Army, Navy), NASA, the Department of Energy and its national laboratories, major defense prime contractors, and — to a more limited extent — commercial satellite operators and medical/industrial sterilization users. Fisica generates revenue primarily through direct hardware sales to government agencies and defense primes via quote-based enterprise contracts, with ancillary professional services revenue from radiation effects testing at the DTRA West Coast Facility and a $5,250-per-participant five-day Flash X-Ray & Digital Imaging training seminar held annually in San Leandro, California. Go-to-market is enterprise field sales supported by trade show presence, an active careers portal, and direct technical content on the corporate website.

Broad incumbents

• L3Harris Technologies: Former parent of Randtron, Datron, and ATI and the largest pure-play defense electronics prime. Directly comparable as the broader portfolio business from which Fisica was carved out, and a direct competitor on antennas, EW, and SATCOM subsystems.
• Northrop Grumman: Defense prime with deep positions in radar, EW, and space systems. Comparable through programs that consume airborne antennas, SATCOM ground systems, and space flight hardware similar to Fisica's portfolio.
• BAE Systems: Global defense prime with EW, communications, and space electronics capabilities. Comparable as a buyer and competitor for similar subsystem content on U.S. and allied platforms.
• RTX (Raytheon): Major defense prime with extensive radar, EW, and space electronics franchises. Overlaps with Fisica on airborne antennas, EW subsystems, and missile/space RF content across multiple platforms.

Direct peers

• Mercury Systems: Specialized defense electronics supplier serving radar, EW, and electronic attack applications with RF and microwave subsystems. Closely comparable business model as a sub-tier supplier of mission-critical RF content to defense primes.
• Comtech Telecommunications: Provider of satellite ground station antennas, TT&C systems, and defense communications solutions. Directly comparable on Datron's full-motion and transportable SATCOM antenna business serving government and commercial satellite operators.
• CPI Satcom & Antenna Technologies: Manufacturer of SATCOM antennas and high-frequency uplink systems for defense and commercial markets. Comparable to Datron's transportable and full-motion antenna lines for satellite communications.
• Kratos Defense & Security Solutions: Defense supplier with unmanned systems, SATCOM, and space hardware franchises. Comparable in serving DoD and space customers with antennas, RF, and flight hardware at similar scale and program tier.
• Cobham Advanced Electronic Solutions: Supplier of ruggedized antennas, RF, and microwave subsystems for defense and aerospace. Closely aligned with Fisica's airborne antenna and COTM product lines serving similar platforms and customers.
