Able to circumnavigate the globe without surfacing and as long as a football pitch, the nuclear engine that powers Britain's brand new class of submarines will never need refuelling for its 25 year lifetime, and is hand built by the people of BAE Systems. This episode shows how the 'first of class' Astute submarine was built and tested and follows her as she prepares to sail into the open sea for the first time.
