Defence

Defence and national security organisations are modernising complex, long-lived systems under strict assurance, security, and operational constraints. OBSS designs, builds, and sustains mission-critical defence software with AI-native delivery embedded across the full lifecycle, within secure, restricted, and air-gapped environments where assurance and continuity are not optional.

With over 20 years of experience and 30+ defence programmes delivered, we operate across NATO-aligned, UK MoD, and EU defence contexts across land, air, and space domains, spanning command and control, avionics, surveillance, and electronic warfare. Our teams combine deep technical expertise with trusted engineering heritage, developing architectures and software that perform to the highest standards of safety, maintainability, availability, and reliability.

OBSS works with defence primes, national security organisations, and NATO-aligned programmes that cannot afford to compromise on assurance, pace, or control.
