UK Launches First Offensive-Defensive Space Squadron

The UK has established No. III Space Effects Squadron as its first unit focused on offensive and defensive space operations. Air Chief Marshal Sir Harv Smyth announced the formation during the inaugural UK Space Power Conference in London on September 23, 2026, with the Ministry of Defence confirming the unit's creation.

No III Space Effects Squadron is the UK's first dedicated military unit tasked with countering hostile threats against British satellites in orbit and other space-related interests. The squadron's task is to disrupt, degrade, and deny enemy activity targeting UK interests in orbit. It will support both defensive and offensive space operations.

Role and capabilities of the new squadron

The unit is expected to employ technologies such as electronic warfare to disrupt, degrade and deny hostile activity. No. III Space Effects Squadron will act using advanced technology, including electronic warfare. Capabilities are set to expand as new systems and technologies enter service.

According to the UK Ministry of Defence, the unit will bring together specialist personnel from across the UK Armed Forces. Chief of the Air Staff, Air Chief Marshal Sir Harv Smith, said the squadron will bring together specialist personnel from across the Armed Forces.

Context within UK's evolving space defence structure

The squadron represents a significant evolution in the UK's approach to space security, moving beyond monitoring and warning to active response. It builds on existing units: No I Space Operations Squadron and No II Space Warning Squadron, established in December 2023, provide capabilities to monitor and detect space-based threats. RAF Fylingdales in North Yorkshire provides continuous missile warning and space surveillance, forming a key part of the UK's wider space domain awareness architecture.

This shift aligns with major strategic documents. The UK Space Strategy, published earlier this month, includes the Control of Space Requirement to maintain freedom to operate in space and deny adversaries the same freedom. Westminster says hostile states are developing new capabilities capable of jamming, disrupting or disabling space-based assets.

The strategy identifies the ability to maintain freedom of action in space, while protecting UK and allied assets and interests, as an increasingly important national security requirement. The Strategic Defence Review stated that the ability to operate in, from, and through space underpins UK security, prosperity, and daily life. Satellites are vital in supporting modern navigation, communications, intelligence, missile warning and maritime activity. Satellite-enabled systems contribute to emergency services, energy infrastructure and networks, weather forecasting and mobile connectivity.

Financial commitments underpin this. Published on 8 September, the UK Space Strategy commits £880m between FY26/27-FY29/30 to space control and intelligence, surveillance and reconnaissance capabilities. In July 2026, the UK government announced six new specialist space squadrons would be trained at the Defence Space Academy.

Statements from senior defence leadership

Air Chief Marshal Sir Harv Smith said space is now a domain of direct competition where military advantage can be won or lost. Defence Secretary Wes Streeting presented a keynote address during the inaugural UK Space Power Conference.

The UK government said it remains committed to the peaceful and sustainable use of space. The UK continues to work through the UN Committee on the Peaceful Uses of Outer Space to promote responsible space behaviors. The creation of No III Space Effects Squadron signals sustained demand for technologies capable of detecting, protecting against and responding to threats in an increasingly congested and strategically important space environment. Capabilities are set to expand as new systems and technologies enter service.
