It is highly complex modern submarines such as the Vanguard Class that are proof of the faith John P Holland and his contemporaries had in the potential of the submarine - although even their expectations could never have envisaged such advanced technology under the waves.
It has never been consistent with the principles of Barrow shipyard or the Royal Navy to rest content with past or present-day successes. Forward thinking and design are constantly in hand by both parties. The latest Astute Class now building at Barrow will be almost twice the displacement of the submarines they will replace and have a nuclear reactor core-for-life which will not require to be refuelled throughout its designed service life.
