A deep dive into the significance of submarines, across everything from warfare and politics to literature and film. Sub Culture explores the crucial role of the submarine in modern history, its contribution to scientific progress and maritime exploration, and how it has been portrayed in art, literature, fantasy, and film. Ranging from the American Civil War to the destruction of the Russian submarine Kursk in 2000, the book examines the submarine's activities in the First and Second World Wars, the Cold War, and in covert operations and marine exploration to the present day. Citing the submarine, particularly the nuclear submarine, as both ultimate deterrent and doomsday weapon, Sub Culture examines how its portrayal in popular culture has reinforced, and occasionally undermined, the military and political agendas of the nation-states that deploy it.
