EnduroSat, a space infrastructure builder, and Shield Space, a veteran-found UK defense technology company, have entered into a strategic partnership to deliver rapidly deployable counter-threat space missions for NATO and allied defense customers. The partnership provides a path for defense organizations to move from contract signature to on-orbit operations in as little as nine months.

Allied forces today face an accelerating threat environment, yet many defense space programs still require years to progress from concept to orbit.

The EnduroSat × Shield Space partnership directly addresses this gap by fusing Shield Space’s mission level autonomous RPO guidance and effector payloads with EnduroSat’s flight proven, software flexible satellite platforms and end-to-end space services.

This allows the companies to introduce a mission as a product approach for defense customers — delivering fully integrated spacecraft, orbital deployment, mission software, and operations as a single package, making the delivery of operationalized space defense missions possible in as little as nine months.

The partnership’s first mission, BROADSWORD, launches in 2027 and serves as the initial proof point for this new operational model. BROADSWORD features an 8U autonomous chaser spacecraft conducting a full RPO sequence against a co-deployed 3U target. The mission demonstrates how Shield Space’s autonomy and effector ready architecture, paired with EnduroSat’s standardized satellite buses and fixed-cost space service, enables rapid defense mission execution at a fraction of the cost of traditional providers.
