UK’s nuclear submarine moves into Arabian Sea as Iran tensions rise

The United Kingdom has deployed HMS Anson, a 7,800-ton nuclear-powered Astute-class attack submarine, to the northern Arabian Sea amid escalating tensions in the Middle East, particularly near the Strait of Hormuz—a critical global oil chokepoint. This strategic move follows Prime Minister Keir Starmer’s authorization for U.S. forces to use UK military bases for potential strikes against Iranian threats to commercial shipping. HMS Anson’s presence provides the UK with a stealthy, long-range strike capability, allowing for rapid response and precision attacks if the conflict intensifies. HMS Anson is armed with Tomahawk Block IV cruise missiles, capable of striking targets nearly 1,000 miles away with mid-flight retargeting and battlefield imaging, as well as Spearfish heavyweight torpedoes designed for underwater and surface threats. The submarine traveled over 5,470 miles from Australia to its deployment zone and operates with high secrecy, surfacing only once daily to communicate with UK command. Powered
