Russian spy sensors have been detected monitoring the UK’s nuclear submarines, raising serious national security alarms. The surveillance operation has been attributed to Russian President Vladimir Putin’s ‘greyzone’ warfare tactics. In response to this threat, the UK is ramping up its defenses by collaborating with technology and energy companies on a new project. Additionally, the country is contemplating implementing more assertive measures such as deploying sea mines around critical areas to safeguard its submarines. This development underscores the ongoing geopolitical tensions and the need for heightened vigilance in the region.
