Terma Acquires OSL Technology To Expand C-UAS & Infrastructure Protection Capabilities

Terma A/S has completed the acquisition of UK-based OSL Technology in a strategic move designed to strengthen its capabilities in Counter-Unmanned Aircraft Systems (C-UAS) and critical-infrastructure protection.

OSL Technology is a specialist in counter-drone and intelligent security systems, with roots in the civil airspace domain where it assists major airports and national infrastructure sites in managing aerial threats. Terma brings decades of experience from the defense and security sectors, supplying radar and command-and-control solutions to navies, air-defense units, and infrastructure operators.

The acquisition combines these distinct civil and defense backgrounds into a single, end-to-end C-UAS solution capable of detecting, tracking, classifying, and responding to threats within seconds.

The joint technology stack integrates defense-grade sensors with AI-driven analytics within an open, modular ecosystem. By combining Terma’s situational awareness heritage with OSL’s full-stack counter-drone suite, the system aims to provide continuous coverage across sea, air, and land. This includes the ability to integrate third-party sensors and effectors, enabling a single operational picture that addresses needs ranging from tactical to strategic levels.

Henriette H. Thygesen, CEO of Terma, highlighted the synergy between OSL’s field experience and Terma’s technical capacity.

Thygesen said, “OSL’s operational performance – from years of protecting critical infrastructure at Heathrow and other major sites – shows it delivers where it matters most. Paired with Terma’s multi-domain capacity, built on decades of delivering situational awareness and defense-grade command-and-control, and further informed by partnerships in Ukraine, we now offer one of the most comprehensive C-UAS suites on the market, helping to set a higher standard for protecting people, airspace, and critical infrastructure. This is not only about Denmark here and now; it delivers a strong, comprehensive C-UAS solution that can contribute to European flagship projects such as the proposed EU drone initiative.”

For airport authorities and defense customers, the combined entity aims to deliver rapid deployment and immediate operational effects.

Mark Legh-Smith, CEO of OSL, stated, “Joining Terma is an extraordinary opportunity for OSL and our customers. Terma’s multi-domain expertise together with our C-UAS platform and agility create unmatched depth of capability – from sensor to decision to response. It means faster detection, smarter classification, and precisely coordinated action. It’s the perfect combination of innovation and assurance.”

MW&L Capital Partners, Kromann Reumert, Addleshaw Goddard, and Deloitte acted as financial and legal advisors to Terma for the transaction. Cavendish and Bird & Bird acted as advisors to OSL.
