How can we help you?
You can find our services, products, publications and more.
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, 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.
Accreditation and configuration discipline embedded at every stage, with AI improving speed and consistency across the full lifecycle.
Senior engineers operating across DevSecOps, mission systems, and defence standards, bringing cross-layer understanding to ensure readiness for complex operational scenarios.
Dual operational presence in the UK and Türkiye enables compliant contracting and seamless cooperation with UK MoD, EU defence partners, NATO primes, and allied organisations.
Strategic partner, contributing to more than 30 major defence programmes.
Government-accepted R&D Centre advancing AI, machine learning and simulation technologies, recognised for innovation in high-assurance engineering environments.
Certified to ISO 9001:2015, ISO/IEC 27001:2022, EYDEP Level A, and NATO Facility Security Clearance (valid through 2030).
Mission-critical engineering across defence, aerospace, and national-security domains.
Command and control systems, C4I systems integration, land and air defence software, and joint operations architectures for complex, multi-domain environments.
Real-time, safety-critical software engineering for embedded mission systems, with system integration, verification and validation.
Electronic warfare and radar systems, AI-enabled ISR and counter-UAS capabilities, and predictive analytics for operational decision advantage.
Mission-grade DevSecOps, simulation and digital twin technologies, and secure delivery environments built for classified and sensitive operational contexts.
A modular, scalable command-and-control foundation enabling interoperability across land and air mission systems, the digital backbone of next-generation joint operations.
Integrated mission-management and situational-awareness platforms connecting radar, sensor, and
communication networks across land and air units.
Our solutions enable real-time operational coordination, decision support, and mission planning
through a unified C4I backbone ensuring faster response, interoperability, and superior situational
awareness in complex battle environments.
End-to-end software design and integration for electronic attack, defence, and coordination systems reinforcing spectrum dominance and operational continuity.
Multi-sensor Counter-UAS platform integrating radar, EO, acoustic, and RF modules with central C2 control. Award-winning computer-vision AI distinguishes drones from birds in real time ranked #1 globally for three consecutive years in the Drone-vs-Bird Detection Challenge.
OBSS provides AI-native software delivery at scale for defence. Begin with a focused diagnostic to assess delivery readiness, modernisation pathways, and AI adoption.
AI-native defence systems engineering means AI is built into the delivery lifecycle from the start. It covers how teams plan, build, test and govern mission-critical software, with AI improving pipeline consistency, compressing verification cycles, and surfacing configuration issues earlier. The result is faster, more predictable delivery within the governance frameworks that high-assurance defence programmes require.
OBSS provides mission-critical software engineering across command and control, C4I systems integration, electronic warfare, and AI-enabled ISR. We design, build and sustain defence software within secure, restricted and air-gapped environments, operating across NATO-aligned, UK MoD, and EU defence contexts to the highest standards of safety, maintainability, availability and reliability.
OBSS holds NATO Facility Security Clearance and is registered on JOSCAR, the single registration system used by the UK and European aerospace, defence and security industries to assess supplier compliance. Additional accreditations include ISO 27001, ISO 9001, and Cyber Essentials. OBSS is a member of MAKEuk Defence, techUK Defence, and the DSEI Gateway programme.
Safety critical software development in defence refers to the engineering of software where failure could result in loss of life, mission compromise, or critical system failure. It requires adherence to formal standards including DO-178C for airborne systems and EN 50128 for rail and embedded applications, with full traceability, verification and validation built into every stage of the delivery lifecycle. OBSS engineers safety critical software for real-time, embedded defence environments where assurance and operational continuity are not optional.
