NSpOC: Sovereign Sensor - Active RF Radar Capability - Further Pre-Market Engagement Notice

**This notice relates to the same procurement as UKSAC26_0005 and represents an update to that procedure: it is not a procurement for a second radar capability** The Department for Science, Innovation and Technology intends to commence a competitive procurement for a sovereign, high-power (~1 MW class) space surveillance radar in the Southern Hemisphere to enhance the UK's Space Surveillance and Tracking (SST) and Space Domain Awareness (SDA) capability. It is expected that this radar system will operate as a key national asset, providing enhanced detection, tracking and custody of resident space objects, particularly small-size debris and operational satellites in Low Earth Orbit. It will deliver significant improvements to UK resilience, space safety, collision avoidance, re-entry monitoring, fragmentation detection and wider civil-military situational awareness objectives.
