New Nuclear Submarine

His Majesty The King welcomed HMS Agamemnon into the Royal Navy, in a

ceremony at BAE Systems in Barrow-in-Furness today [22 September], before
conferring Royal status on the Port of Barrow. In a separate ceremony led
by the Defence Secretary, steel was cut on the fourth and final Dreadnought
Class submarine, King George VI, marking the start of its construction. The
work reinforces the Government’s commitment to the ‘triple-lock’ on
the deterrent: building four new nuclear submarines; maintaining our
continuous at sea nuclear deterrent; and delivering all future upgrades
needed.
