The United Kingdom’s military is actively jamming the satellites of other nations as a defensive measure, the head of the Royal Air Force has revealed, describing the threats Britain faces in space as unprecedented. The disclosure marks a rare public acknowledgement of offensive space operations by a Western military.

The comments came alongside the announcement of a new unit dedicated to defending Britain’s satellites, underscoring how space has become a contested domain for military competition.

Unprecedented threats

The RAF chief told the BBC that adversaries are increasingly targeting space-based assets that underpin everything from military communications and navigation to civilian infrastructure. Jamming, which disrupts the signals satellites send and receive, is one of the tools being used both against the UK and by it.

The new unit will focus on protecting Britain’s space capabilities, monitoring hostile activity and responding to threats in orbit.

Space as a battleground

The revelation reflects a broader global trend. Major powers including the United States, China and Russia have all been developing space warfare capabilities, from jamming and dazzling to anti-satellite weapons that can physically destroy orbital assets.

Defence analysts say the public acknowledgement by the UK signals that space is no longer treated as a purely supportive domain but as a warfighting one in its own right.

What it means

For Britain, the move is about deterrence and resilience: ensuring that its satellites keep working even as adversaries try to disrupt them. For the wider world, it is another sign that the norms governing behaviour in space are under strain.

Efforts to establish rules of the road for military activity in orbit have so far made limited progress, and disclosures like this one are likely to intensify the debate.

Defence experts add that protecting satellite navigation and communication is now as critical as defending physical borders, given how deeply modern militaries depend on space.
