UK to Launch New RAF Squadron to Defend Military Satellites
The United Kingdom will establish No. III Space Effects Squadron, a Royal Air Force unit tasked with defending British military satellites.
Defence Secretary Wes Streeting will announce the unit on Wednesday, September 23, 2026, according to details released ahead of the statement. Air Chief Marshal Sir Harv Smyth, Chief of the Air Staff, is also scheduled to address the creation of the squadron at the UK's Space Power Conference on Wednesday. The Guardian
The squadron will protect satellites used to warn of incoming missile attacks, provide communications and help guide ships, according to the Ministry of Defence. It will bring together specialist personnel from across the UK armed forces to counter hostile activity in orbit. Its remit covers both offensive and defensive space operations, and the Ministry said the unit will expand over time as new capabilities enter service.
Its main tools will be advanced technology including electronic warfare, which means using radio signals and other invisible energy to block or confuse hostile systems without firing a weapon. The Ministry described No. III Space Effects Squadron as the UK's first unit dedicated to disrupting, degrading and denying hostile threats in space. GOV.UK
The mission builds on an existing structure. Two RAF units, No. I Space Operations Squadron and No. II Space Warning Squadron, already allow the RAF to watch and warn of threats in space, much like radar operators who spot incoming aircraft. The new squadron adds an effects layer to that watch-and-warn foundation, meaning the ability to respond and not only observe. The RAF has published an official announcement titled 'RAF launches first ever space squadron' for the unit, and its site map now lists '3 Space Effects Squadron' among its squadrons. RAF
Smyth said at the Space Power Conference that the new No. 3 Space Effects Squadron will deliver precise, integrated effects to safeguard national interests in space, according to the published text of his remarks. GOV.UK
The announcement keeps one stated limit. The UK has formally ruled out destructive anti-satellite missile testing, which means blowing up satellites with missiles. UK Space Command said last year that Russia was attempting to jam UK military satellites on a regular basis.
The broader context here is a shift from observation to action without crossing into physical destruction. Watch and warn means detection, tracking and characterization. Disrupt, degrade and deny means reversible or non-destructive interference, with electronic warfare as the stated instrument. For planners who rely on missile warning, protected communications and positioning for ships, that distinction affects how capability is preserved while limiting debris and escalation risk.
Looking at what this means for force design, the personnel model is as important as the technology. Drawing specialists from across the armed forces points to a joint effects unit under RAF command rather than a single-service trade group. The pledge to expand as new capabilities enter service leaves room for incremental authorities, payloads and ground systems. Diplomats will read a parallel message. A public renunciation of destructive testing paired with investment in non-kinetic effects fits a wider effort to set norms for responsible behaviour while retaining leverage in orbit.
