Eighteen years after committing to renewing the UKโ€™s nuclear deterrent, the keel was laid on HMS Dreadnought as the country's new weapon reached a milestone.

Prime Minister Sir Keir Starmer performed the honors as work started on the backbone of the first of four third-generation ballistic missile submarine in Barrow, nearly 10 years since the first steel was cut.

Displacing more than 17,000 tons, the length of 14 buses and with a crew of around 130, the Royal Navy said the HMS Dreadnought will be the most-advanced boats of their kind in service anywhere. They will include features like โ€˜adaptiveโ€™ lighting to simulate day and night on board. The boats are expected to have a lifespan of more than 30 years.

Building the Dreadnought class is a national endeavor, with some 30,000 people involved in the project from design through to delivery, with the construction phase of the four submarines โ€“ HMS Valiant, Warspite and King George VI follow the first in class โ€“ expected to take 20 years.

The boats themselves are being built in 16 โ€˜unitsโ€™ which, when ready are grouped into three โ€˜mega unitsโ€™ and moved to the Devonshire Dock Hall for assembly; the first โ€˜mega blockโ€™ of Dreadnought was delivered in the autumn of 2023.

Dreadnought is due to begin its deterrent patrols next decade as the existing V-boats (the oldest, Vanguard, is already 33 years old, the youngest, Vengeance, 27) are phased out.
