UK military jams foreign satellites to shield its nuclear submarines

UK military jamming other nations' satellites to defend itself, BBC told

The RAF has spent the past year using a ground-based electronic warfare system to jam or block other nations' satellites, a defence source told the BBC, saying it has already been used "to deter our adversaries." The capability could hide the movement of the UK's nuclear-armed submarines or special forces operations. It emerges as the RAF stands up a new Space Effects Squadron and warns of "unprecedented threats" in orbit.
