Construction of Royal Navy’s First Dreadnought-Class Nuclear Submarine Progresses at BAE Systems’ Yard in Barrow

The construction of the UK Royal Navy’s first Dreadnought-class nuclear-powered ballistic missile submarine (SSBN) is progressing at BAE Systems’ yard in Barrow, England.

Recently, a section of the first Dreadnought submarine has been moved for the assembly. The unit was the first to make use of new material designed to improve protection for submarine sections as they are moved around the site during construction.

The Dreadnought programme is one of the most complex engineering projects ever undertaken and employs more than 7,000 people across industry and MOD, with thousands more in the supply chain.

Four Dreadnought-Class submarines will be built at Barrow-in-Furness shipyard by BAE Systems Submarines to replace the Vanguard-Class SSBNs that are currently in service with the Royal Navy. Like their predecessors, Dreadnought-Class SSBNs will carry UGM-133A Trident II (D5) submarine launched ballistic missiles (SLBM).

Provisionally named “Successor” (being the successor to the Vanguard class SSBNs), it was officially announced in 2016 that the first of class would be named HMS Dreadnought, and that the class would be the Dreadnought class. The next three boats will be called HMS ValiantHMS Warspite and HMS King George VI.

Once built, the submarines will measure 153.6m long, with a displacement of 17,200 tonnes. HMS Dreadnought, the first of the new fleet, is scheduled to be delivered in the early 2030s.
