This episode has been inspired by the tragedy of the Nanggala, a submarine of the Indonesian navy that disappeared earlier this month with 53 crew members on board and only 72 hours of oxygen to keep them alive. After 5 days of searching Nangala was found at a depth of more than 800 meters, split into three sections. This has led to a great deal of discussion in the press about submarine design. In this episode Dr Sam Willis talks with Andrew Choong Han Lin, curator of ships plans and technical records at the National Maritime Museum in London. They discuss the fascinating history of the British K-class submarines of the First World War that became infamous for their poor design. To go alongside this podcast episode we have animated the fabulous ship plans for the K-Class submarines that are held in the collections of the Caird Library at the National Maritime Museum.
