Electro Optic Systems (EOS) is a Canberra-based, ASX-listed technology and manufacturing company with more than four decades of activity in defence and space. The firm operates through two divisions: Defence Systems, which focuses on weapon-system optimization, autonomous platforms, and ISR for land warfare, and Space Systems, which supplies electro-optic equipment and services for space domain awareness, surveillance, and communications. The company emphasises intellectual-property ownership and vertical design to support long-term obsolescence management, helping it bring evolving technologies to market. EOS serves international space agencies, satellite operators, and defence organisations, providing capability across imaging, tracking, and command-and-control for space and land-based operations. Based in Canberra, it is a mid-sized firm with hundreds of employees operating globally in defence and space missions. A notable development in 2026 saw EOS Defense Systems USA take a mission-partner role on a naval unmanned vessel program, supplying the vessel's gun system as part of its configuration.
