In this episode Rory follows British maritime tradition from ships rooted deep in British history through to submarines that are still being built.

British engineering at sea has always been nothing short of ground-breaking. In the 18th century Admiral Nelson’s 100 gun flagship, HMS Victory, dominated the battle of Trafalgar and little over 100 years later Brunel’s SS Great Britain became the talk of the seafaring world with its ground-breaking propulsion system.

The 20th century saw the advent of the truly great transatlantic passenger liners, of which the Queen Mary was the most famous, enjoying distinguished careers in both civilian and military service.

To cap it off, discover the cutting-edge technology of the electronically-controlled modern lifeboat and the deadly capabilities of Britain’s new multi-billion pound submarine fleet.
