Britain has begun construction on the third of four new strategic submarines of the Trident II D-5 ICBM type, the Royal Navy said on Thursday.
BAE Systems at Barrow-in-Furness shipyard in Cumbria has begun work on cutting metal for the submarine’s hull. In addition to it, two submarines of this type are already in various stages of construction – Dreadnought and Valiant.
They are to replace the UK’s four Vanguard-class strategic submarines, which have been the backbone of Britain’s nuclear forces since the 1990s and are due to retire in the early 2030s.
Each Dreadnought-class submarine will carry 12 Trident II D-5 intercontinental ballistic missiles, equipped with multiple reentry vehicles with 8 nuclear warheads.
