For ten years George Deeming worked at ESR in a team dedicated to the design of a secret project named in this memoir as The Sentinel Project, fitted to improved Valiant class, nuclear submarines, including HMS Conqueror. As with WW2 there are many books and articles on actual conflict, but this story is unique as it relates to the Falklands War at home, the humorous and serious episodes of factory life and includes a first hand account of a Belgrano survivor and one of the crew aboard Conqueror. Sinking of the Belgrano remains controversial in some circles, but at ESR the news was greeted by a prolonged silence.As he approaches retirement George is taking tentative steps to visit the Falklands to see the penguins and considering travelling to Argentina to meet Marcelo. Only time will tell if George will realise his dream.
