RAF Fylingdales Solid State Phased Array Radar (SSPAR) Upgrade

RAF Fylingdales, North Yorkshire, UK · 1990 (upgrade began) - 1992 (SSPAR declared operational); subsequent upgrades ongoing.

The judgement call

Account-gated at launch

The SSPAR upgrade significantly enhanced the capabilities of RAF Fylingdales, moving from rotating 'golf balls' to a fixed, more powerful system. - The facility provides a continuous ballistic missile early warning service and space surveillance for the UK and US governments. - The long-standing collaboration between the UK and US at Fylingdales is a key aspect of transatlantic defence cooperation.

Key engineering challenges

Replacing the older mechanical radars with a more capable solid-state phased array system. - Ensuring continuous missile warning capability for both the US and UK. - Integrating advanced signal processing and data analysis for improved threat detection and tracking. - Maintaining operational readiness and resilience in a critical defence role.
