Britain’s New Submarine Is Shocking Everyone

Britain has kept a nuclear deterrent submarine at sea every day since April 1969, but the Vanguard boats that carry it are far older than they were designed to be. This video follows HMS Dreadnought, the first of four replacement submarines being built at Barrow-in-Furness, and explains why it has taken around sixteen years from first steel to first patrol. You will learn how the new boat's Rolls-Royce reactor, its missile compartment shared with America's Columbia class, and the wider supply chain fit together. You will also see why the Vanguards have been spending more than six months at sea, and why the £41 billion programme cost and any further delay put the gap at risk. If you want to understand what keeps the deterrent running until Dreadnought arrives, this covers it.
