A British nuclear-powered submarine outfitted with Tomahawk cruise missiles has taken place within the Arabian Sea, giving Britain the aptitude to launch long-range strikes if regional battle escalates, the Daily Mail reported on Saturday (March 21, 2026).
Reuters couldn’t instantly confirm the report. The British Ministry of Defence didn’t instantly reply to a Reuters request for remark.
HMS Anson, armed with Tomahawk Block IV missiles and Spearfish torpedoes, left Perth earlier this month and travelled roughly 5,500 miles to the area, the Every day Mail stated.

The submarine surfaces periodically to speak with the U.Okay.’s Everlasting Joint Headquarters in Northwood, the place any launch order can be authorised by the prime minister and conveyed by the chief of joint operations, the report added.
The deployment comes after Downing Avenue authorised the U.S. to make use of British bases for strikes on Iranian websites threatening the Strait of Hormuz.
