"Following an extensive sweep of the Devonshire Dock Complex (DDC), including the four Astute class submarines in build, nothing suspicious was found," the company said in a statement. "We expect to be able to close the incident shortly."
It did not specify the nature of the incident but an unidentified source told The Mail, a publication based in Barrow-in-Furness, that the evacuation followed a warning about a bomb on one of the Astute-class submarines. Ambulances and police were called to the shipyard.
Barrow-in-Furness also makes the new generation of four Dreadnought-class ballistic missile submarines that from 2028 onwards will replace the Vanguard class vessels which form the basis of the United Kingdom's Trident nuclear deterrent. Dreadnought-class submarines will measure 153 metres long, with a displacement of 17,200 tonnes, and have a PWR3 nuclear reactor.
BAE Systems, Rolls Royce and Babcock are the main industrial partners in the 31-billion pound ($41 billion) Dreadnought project. (Reporting by Guy Faulconbridge, Kate Holton and Paul Sandle; editing by Stephen Addison)
