Aeronix Technologies Group

Aeronix Technologies Group (ATG) is a Melbourne, Florida-based holding company formed by an undisclosed family office to consolidate complementary defense-electronics businesses. The group comprises three operating units: Aeronix, which specializes in secure communications and electromagnetic spectrum operations (EMSO), ITI Engineering, a developer of mission-planning and data-transfer systems for the F-35 and other aircraft, and Systems Integration Plus, a systems integrator for ruggedized computing. ATG states it has over 35 years of combined experience and operates across six U.S. states. ATG targets the U.S. Department of Defense and allied nations, supplying hardware and software for airborne platforms including the F-35, F-22, F-16, and F-15. The group's capabilities cover data-transfer devices, ruggedized computers and switches, software-defined radios, custom crypto, and waveform development. ITI Engineering secured a multi-million-dollar order for F-35 ruggedized server systems and a multi-million-dollar contract to sustain F-35 mission systems (per the firm's website, 2025). The firm reports that +70% of its workforce are engineers. A key structural differentiator is ATG's three-company model under a single family-office sponsor, allowing it to combine small-company speed with the capacity to bid on prime-level contracts. The group owns specialized manufacturing and office facilities across Florida, South Carolina, Texas, Arizona, Colorado, and Virginia, and serves customers in North America, Europe, Asia, and the Middle East.
