Britain has taken a major step into a new era of defence, with the Royal Air Force launching the country’s first dedicated space squadron tasked with protecting vital satellites and countering hostile activity in orbit.
No. III Space Effects Squadron has been established to disrupt, degrade and deny threats against British interests in space, as the UK strengthens its ability to defend the increasingly important infrastructure orbiting above the Earth.
The new unit was announced by Chief of the Air Staff, Air Chief Marshal Sir Harv Smyth, at the inaugural UK Space Power Conference this week.
It marks a significant development for the RAF, taking Britain beyond simply detecting and monitoring threats in space and giving the Armed Forces a dedicated unit capable of responding to them.
Specialist personnel from across the Armed Forces will serve with the squadron, which will use advanced technology, including electronic warfare, to disrupt, degrade and deny hostile actions.
The unit will support both defensive and offensive space operations, with its capabilities expected to grow as new systems enter service.
The importance of protecting Britain’s interests in space extends far beyond the military.
Satellites support intelligence gathering, missile warning, navigation and military communications, but they are also woven into everyday civilian life.
Mobile communications, weather forecasting and navigation all depend upon space-based technology. Britain’s police, firefighters and ambulance services use satellite navigation when responding to emergencies, while satellite systems also play a role in the operation of energy networks.
Modern Britain, in other words, increasingly depends upon what happens hundreds or even thousands of miles above our heads.
No. III Squadron will work alongside the RAF’s existing No. I Space Operations Squadron and No. II Space Warning Squadron.
Those units provide the ability to observe activity and warn of potential threats, while the newly established squadron will provide the capability to act against them.
It comes amid growing concern about the ability of hostile states to interfere with satellites through jamming, disruption and other anti-satellite capabilities.
Air Chief Marshal Sir Harv Smyth said space was now a domain of direct military competition, rather than something which merely supported conventional operations.
He said the new squadron would protect the advantages space provides to Britain’s integrated Armed Forces, while also being capable of denying those advantages to adversaries.
The development is part of Britain’s wider effort to maintain what defence planners describe as “freedom to operate” in space.
Under the UK’s Control of Space Requirement, Britain intends to preserve its ability to use space-based capabilities while developing the means to prevent adversaries from enjoying the same freedom when they threaten British interests.
The requirement forms part of the UK’s new Space Strategy and follows the Strategic Defence Review’s recognition that the ability to operate in, from and through space is increasingly important to Britain’s national security and prosperity.
The UK is also investing £880 million between 2026/27 and 2029/30 in space-based intelligence, surveillance and reconnaissance, alongside space-control activities.
Defence Secretary Wes Streeting used the announcement to argue that Britain must keep pace with what he described as the new “space race”.
Drawing parallels with Britain’s historic maritime and air power, he said control of the seas had been crucial to deterrence in the 19th century, while control of the skies became essential in the 20th.
“This century will depend on control of space,” he said, warning that Britain’s growing reliance on satellites meant they were increasingly becoming targets for potential adversaries.
Despite the development of its military space capabilities, Britain has formally ruled out destructive anti-satellite missile testing.
The UK also continues to participate in the United Nations Committee on the Peaceful Uses of Outer Space, supporting international rules and principles intended to encourage responsible behaviour beyond the Earth’s atmosphere.
But the creation of No. III Space Effects Squadron demonstrates how dramatically the defence landscape is changing.
For more than a century, the RAF has adapted to new threats and new technologies, from the earliest days of military aviation to radar, jets, missiles, cyber warfare and remotely piloted aircraft.
Now Britain’s airmen and women are preparing for another frontier.
The Royal Air Force was created to defend Britain’s skies. More than a century later, its responsibilities are stretching far beyond them.
