What Bertel O. Steen Defence & Security does

Bertel O. Steen Defence & Security AS is a Norway-based defence and security trade and service company, operating as a sub-group of the 1901-founded family-owned Bertel O. Steen Group. It functions as the Nordic representative for a roster of international defence manufacturers — including ThyssenKrupp Marine Systems, Rheinmetall, KNDS, Diehl Defence, Mercedes-Benz Defence, Leonardo, Milrem Robotics, L3Harris, Textron, and Heckler & Koch — managing the full lifecycle of defence equipment in Norway, Sweden, and Denmark through three pillars: Advisory Services (capture planning, stakeholder management, industrial cooperation support for Nordic defence investment programs), Aftermarket Services (maintenance, repair, overhaul, contractor logistics support, and in-service support positioned near every Norwegian military base), and Tactical Solutions (a portfolio of lighting systems, thermal and night vision optics, body armour, EOD solutions, C-UAS/A2-AD equipment, and the Snowmotion military snowshoe co-developed with Rottefella and the Norwegian Army's School of Winter Warfare). Its three Nordic offices (Oslo headquarters, Stockholm, Glostrup) and longstanding relationships — including a multi-decade advisory role on the Ula-class and follow-on submarine programs and an NDLO strategic partnership for civil-military total-defence cooperation since 2018 — position it as a system integrator and trusted advisor between OEM principals and Scandinavian armed forces, law enforcement, and search-and-rescue end users.
