Defence Secretary John Healey has issued a stark warning to Russian President Vladimir Putin, declaring, ‘We’re hunting your submarines.’ Healey revealed a 30% increase in Russian vessels encroaching on UK waters, signaling a broader pattern of Russian aggression that extends beyond Ukraine to impact Europe as a whole. The Ministry of Defence confirmed that Russian submarine activity in the North Atlantic has surged to levels reminiscent of the Cold War era. In response, the RAF and Royal Navy have intensified their surveillance efforts, with RAF P-8 aircraft conducting frequent missions, often supported by NATO allies. BBC News accompanied Healey on a flight aboard a P-8, a high-tech spy plane equipped with advanced cameras, sensors, and sonar buoys designed to detect and track submarines. The crew, working in a highly classified environment, monitors both surface vessels and underwater threats. Recent incidents, such as the tracking of the Russian spy ship Yantar near undersea cables in the Irish Sea, highlight growing Western concerns over Russia’s potential to disrupt critical infrastructure. Germany, a key ally, has ordered eight P-8 aircraft and is deepening its defense collaboration with the UK under the Trinity House Agreement. German Defence Minister Boris Pistorius, who joined Healey on the flight, emphasized the North Atlantic’s strategic importance and the need for vigilance against Russian hybrid warfare tactics, including disinformation and threats to undersea infrastructure. The two nations are also cooperating on cybersecurity and arms production, further solidifying their partnership in the face of escalating Russian threats.
