The UK's military has admitted it deliberately jams other countries' satellites when it considers them a security threat.
British defence officials described the practice as defensive, not offensive, aimed at protecting UK military and civilian assets in orbit rather than disrupting rivals for the sake of it. The disclosure is unusual: electronic warfare capabilities like satellite jamming are typically kept classified, with governments preferring plausible deniability over public confirmation. Satellites now underpin everything from GPS navigation to secure communications, making them both harder to ignore and easier to justify defending. The admission suggests the UK sees enough strategic or diplomatic value in transparency here to outweigh the usual instinct toward secrecy.
Jamming sits in a deliberately murky part of modern conflict. It's disruptive without being destructive, reversible, and notoriously hard to attribute - which is exactly why most militaries avoid confirming they do it at all. By going on record, the UK normalizes a tool that adversaries and allies alike already use but rarely acknowledge, and it invites the obvious question of where "defensive" jamming ends and something more aggressive begins.
"Defensive" is doing a lot of work in that sentence - the satellite on the receiving end doesn't get a vote on the label.
