'Underhand and damned un-English' was the view of submarines in Edwardian Britain. However, by the 1960s new nuclear powered submarines were seen by the Royal Navy as being the 'hallmark of a first class navy'. This exciting new book explores the changing attitudes to the submarine in Britain from World War One to the age of nuclear combat. Including discussion of unrestricted submarine warfare, the experience of the world wars, nuclear power and weapons, as well as films and novels based on submarine warfare, this book is essential for naval historians, students and those interested in aspects of submarine development and use.
