Between 15 June 1968 and 13 May 1996, the Polaris submarines of the 10th Submarine Squadron carried out a total of 229 patrols, travelling over 2 million miles. Wherever you sit on the nuclear debate, it makes an impressive tale; delivered on time and on budget essentially by a small group of naval officers and civil servants, the Polaris programme ensured that Britain had a Continuous at Sea Deterrence for twenty-eight years. Polaris is not just the history of the weapons, submarines and politicians: it is the history of those who were there. Combining through history with personal memories and photographs, Keith Hall has created a long-lasting legacy to a fascinating project and provided an insight into a world that no longer exists.

KEITH HALL was a Health Physics Specialist at HM Naval Base Clyde. He served in the Royal Navy for over 30 years, both on nuclear submarines and in shore positions in support of the naval nuclear propulsion program. He has previously written Rosneath and Garleloch, HMS Defiance: Plymouth's Submarine Base, HMS Dolphin: Gosport's Submarine Base, Submariners' Tales from the Deep and Clyde Submarine Base for The History Press.
