On 23 September 2026, Defence Secretary Wes Streeting used his keynote at the UK Space Power Conference to turn a broad policy argument into a concrete force-development announcement. He opened with an operational update on the Hawk T2 crash near RAF Valley in Anglesey, saying both crew had ejected and been taken to hospital, before shifting to the main theme of the speech: space is now being treated as a direct defence domain rather than a remote technical specialism. (gov.uk) The immediate announcement was the creation of No. III Space Effects Squadron, which the Ministry of Defence describes as the RAF’s first dedicated unit for countering hostile threats to UK satellites. In policy terms, that is the speech’s main development: Whitehall has moved from stating a "Control of Space" requirement to establishing a named formation intended to deliver it. (gov.uk)
The speech sits inside a sequence of defence papers published across 2025 and 2026. The Strategic Defence Review 2025 describes space as a critical national infrastructure sector and a domain central to warfighting. The UK Space Strategy, published on 8 September 2026, then set out a one-government plan backed by more than £7.8 billion to 2029/30, with defence, national security and economic growth given explicit priority. (gov.uk) The funding case is also more defined than in earlier UK space policy. The Defence Investment Plan funding explainer allocates £3.2 billion to space capabilities over the next four years, while the strategy commits £880 million between 2026/27 and 2029/30 for space control and intelligence, surveillance and reconnaissance, alongside £2.8 billion for connectivity programmes including SKYNET and low Earth orbit systems. The conference announcement therefore sits inside a stated spending programme rather than standing alone as conference messaging. (gov.uk)
No. III Space Effects Squadron is intended to do more than observe orbit. According to the Ministry of Defence, the unit will support offensive and defensive space operations, using technologies including electronic warfare to disrupt, degrade and deny hostile activity targeting UK interests in space. The speech linked the squadron to wider work on orbital warfare and counter-satellite capabilities, while also presenting those capabilities as part of deterrence and resilience rather than an attempt to normalise conflict in orbit. (gov.uk) That role changes how the RAF’s space structure is now presented. The ministry says No. I Space Operations Squadron and No. II Space Warning Squadron provide the ability to watch and warn; No. III is the unit intended to act. On the published force structure, that suggests a move away from a surveillance-only posture towards one that can generate operational effects as part of joint and allied planning. (gov.uk)
Streeting framed space as both a military dependency and a civil vulnerability. In the speech, he said satellites are essential to intelligence gathering and missile warning, but also support weather forecasting, energy supply, financial transactions, satellite navigation, mobile phone connections and online deliveries. The Strategic Defence Review makes the same point in more formal terms, stating that assured access to operate in, from and through space underpins the UK’s security, prosperity and daily life. (gov.uk) The economic case is intended to make the security argument concrete. Streeting said satellites underpin almost a fifth of the UK economy and that the loss of GPS alone would cost £1.4 billion a day. The Ministry of Defence press release adds practical examples outside defence: emergency services depend on satellite navigation, energy networks use it to manage power grids, and missile warning depends on space-based assets. The policy change therefore reaches well beyond the armed forces. (gov.uk)
The threat picture in the speech closely matches the Government’s recent defence documents. Streeting referred to Russia’s war in Europe, hostile probing of airspace and undersea infrastructure, cyber attacks, and rising risks from space. The Strategic Defence Review likewise warns that attacks affecting military and civilian critical national infrastructure, including space-based systems, are plausible features of future confrontation with state adversaries. (gov.uk) On capability trends, the Strategic Defence Review states that the combined Chinese and Russian operational satellite fleets grew by 70 per cent between 2019 and 2021, a figure repeated in the speech. Streeting used that context, and the rapid tactical change seen in Ukraine, to argue that Britain cannot prepare only for legacy forms of conflict. The message was that space should now be treated as a contested operational environment, not a permissive support layer. (gov.uk)
Although the speech was framed around harder deterrence, it also stressed alliance management and restraint. Streeting said the UK could not achieve its aims alone and described NATO as the cornerstone of British defence, while backing a NATO-first approach alongside wider partnerships. The UK Space Strategy uses similar language, presenting control of space as something to be delivered with allies and partners as well as through sovereign capability. (gov.uk) The Government is also trying to show that stronger military capability in orbit does not mean dropping its public commitments on responsible behaviour. The Ministry of Defence says the UK has ruled out destructive anti-satellite missile testing and continues to work through the UN Committee on the Peaceful Uses of Outer Space to promote responsible conduct. That matters politically because any unit designed to deny adversaries freedom of action in space will attract scrutiny over escalation, attribution and debris risks. (gov.uk)
The speech also tied space policy to industrial policy. Streeting presented defence spending as support for British industry, skills and jobs, noting that almost 70 per cent of defence jobs are outside London and the South East and arguing that a larger space role should create openings in digital technologies, telecoms, robotics and apprenticeships. The Government’s 8 September strategy similarly presents space as a growth sector supporting more than 55,000 skilled jobs. (gov.uk) Taken together, the speech, the September strategy and the summer investment plan mark a clear change in UK defence policy. Space is no longer being described only as an enabling service; it is being organised as an operational theatre with dedicated units, named spending lines and a stated requirement to protect UK and allied interests while being able to deny adversaries the same freedom. On the published papers, the next test will be delivery: doctrine, training, procurement and alliance coordination will need to catch up with the new squadron announcement. (gov.uk)
