The shipyard has been awarded contracts for the construction of submarines which will carry nuclear missiles in a successor programme to the current "Vanguard" class containing the Trident system. BAE Systems is investing £300 million in Barrow's shipyard to construct buildings capable of manufacturing and assembling the new class of submarines. This major development is the largest in 25 years at the shipyard and will see thousands of new jobs created, further cementing its place as the UK's largest shipyard and one of the few to have seen continuous contracts since founding over a century ago.
