The company's flagship product is the Legolas MK1 system, a jet-powered, AI-guided counter-UAS interceptor. Sphere Defense's technical domains span counter-UAS systems, AI-guided interceptors, and jet-powered propulsion. The company serves defense, military, and government authorities, as well as operators of sensitive infrastructure.

Headquartered in Belgium with a European footprint, Sphere Defense emphasizes sovereign capabilities and an EU-centric, conflict-resilient supply chain. Its systems are engineered in Belgium and manufactured in Europe, aligning with the strategic priorities of European defense autonomy.
