A busted rudder forced the British ballistic missile submarine HMS Vigilant to dock for repairs at a U.S. base, the Herald Scotland reported on Sunday.
The trouble occurred as the vessel was returning to its home berth in Scotland after conducting an Oct. 23 trial launch of a Trident missile near Florida. The submarine is now at the Naval Submarine Base Kings Bay in Georgia.
The British Defense Ministry did not offer an official cause for the incident, but said the Vigilant had not hit another oceangoing vessel. One insider said the submarine came into contact with ocean junk.
The Royal Navy spent $486 million over three years to update the vessel, one of four Trident submarines that make up the United Kingdom's nuclear deterrent. Observers raised worries about how the Vigilant could sustain rudder damage in the wake of such a refurbishment, according to the report.
