The Royal Navy has deployed HMS Anson, a nuclear-powered Astute-class submarine, to the Arabian Sea in response to escalating tensions with Iran. The deployment comes after Iran’s failed ballistic missile attempt targeting Diego Garcia, a key U.S.-U.K. military base in the Indian Ocean. The submarine, armed with Tomahawk Block IV cruise missiles and Spearfish heavyweight torpedoes, traveled approximately 5,500 miles from Australia to the region earlier this month.
Strategic Positioning
HMS Anson is reportedly operating in the northern Arabian Sea, positioning Britain to respond swiftly if the conflict intensifies. The submarine periodically surfaces to maintain communication with the U.K.’s Permanent Joint Headquarters in London. This deployment follows the U.K. government’s authorization for the United States to use British military bases for defensive operations against Iranian missile capabilities threatening shipping in the Strait of Hormuz.
We didn’t participate in the initial strikes, and we’re not getting drawn into the wider war.
Downing Street emphasized that the operations aim to 'degrade the missile sites and capabilities' used in attacks on ships while avoiding a broader regional conflict. Iran’s recent missile launches, which failed to reach Diego Garcia, have raised concerns about Tehran’s missile range and intent. Iranian Foreign Minister Seyed Abbas Araghchi warned Britain against supporting U.S. or Israeli military actions, claiming such involvement could escalate the situation.
Defensive Operations Continue
The U.K. Ministry of Defence confirmed that Royal Air Force assets, including Typhoon jets, remain engaged in defensive operations in the region. British forces have also reportedly countered Iranian drone threats and coordinated closely with allies. While the U.K. did not allow the U.S. to use its bases for initial offensive strikes against Iran, it later granted permission for defensive operations in response to Iranian missile threats.
