RAF Stands Up No. III Space Effects Squadron to Disrupt, Degrade and Deny Hostile Activity in Orbit — GBP 880 Million for Space-Based ISR and Control
London, 23 September 2026
Key points
- Air Chief Marshal Sir Harv Smyth announced No. III Space Effects Squadron at the UK Space Power Conference on 23 September as the RAF unit dedicated to countering threats to British satellites, "using advanced technology, including Electronic Warfare, to disrupt, degrade and deny hostile actions"
- It joins No. I Space Operations Squadron and No. II Space Warning Squadron, which watch and warn; the new squadron will "act against those threats", support offensive and defensive space operations, draw personnel from across the armed forces and "expand over time as new capabilities enter service"
- The Ministry of Defence sets it on "an £880 million investment between 2026/27 and 2029/30 in space-based Intelligence, Surveillance and Reconnaissance and space control activities" and on the Control of Space Requirement in the UK Space Strategy published earlier in September
- No base, headcount, equipment or in-service date is given. The UK has formally ruled out destructive anti-satellite missile testing
Britain's space order of battle now has a unit whose job is to act rather than to watch, and the announcement names no equipment, no base and no headcount for it.
Smyth: "Space no longer supports operations from the sidelines. It's a domain of direct competition, where our military advantage can be won or lost." The squadron, he said, will safeguard the benefits space gives the armed forces "and will be capable of denying those benefits to our adversaries". Wes Streeting, in the keynote, set control of space beside control of the seas in the nineteenth century and of the skies in the twentieth, and said the threat to British satellites "is growing in scale, speed, and sophistication". The release lists what the satellites do, from missile warning and intelligence to navigation for ambulances and timing for power grids, and describes the capability set as electronic warfare and "countermeasures against anti-satellite weapons".
The money is a programme figure, not the squadron's. GBP 880 million across four financial years covers space-based ISR as well as space control, and the release does not split it. The lineage is the Strategic Defence Review, the Space Strategy of this month and its Control of Space Requirement, the need to keep freedom to operate in space and deny it to adversaries. Because the UK has ruled out destructive anti-satellite testing, the squadron's menu is reversible effects: jamming, dazzling and cyber, the class of effect NATO members have been on the receiving end of over the Baltic for two years.
Electronic warfare against satellites is a capability every space command claims and none itemises, and the squadron follows the pattern: the effect is named, the effector is not. The comparator is Germany, where Pistorius has offered Uedem to host a European space component command; Berlin is building a headquarters, London a squadron, and neither has published a system. The observable for No. III is a contract, a site or a named ground station, any of which would say what "disrupt, degrade and deny" is done with. Signal No. 152 carried the announcement without a Signal line, which is where the record stops.
