The family then moved to New Zealand before Moore was sent to Sherborne, an independent boys' boarding school in Dorset, to complete his education.
During the World War II, Moore became acquainted with the difficulties experienced in getting men from submarines to land and later in his career he devoted much attention to this subject.
While in command of the Seventh Submarine Division in Singapore in the mid-60s during the period of confrontation between Malaysia and Indonesia he carried out experiments with the Special Boat Service (SBS) of the Royal Marines Commandos, working closely with a young 2nd lieutenant in that unit called Paddy Ashdown, later to become a British MP and latterly Lord Ashdown.
Moore designed a device which he named 'Trongle' that allowed submariners to locate their vessel in the hours of darkness, revolutionising the way the SBS operated.
During this period the first personal computers became available, but Moore did not use one, preferring a manual filing system in a shed in the garden at his home in Rickney, Sussex and communicating with contacts worldwide by letters written in longhand, Besides editing 15 editions of Jane's Fighting Ships and other works published by Jane's, Moore published several books including: The Soviet Navy Today (1976);[1] Warships of the Royal Navy (1979);[2] Seapower and Politics from the Norman Conquest to the Present Day (1979);[3] Warships of the Soviet Navy (1981);[4] The Encyclopedia of the World's Warships(1985);[5] (with Richard Compton-Hall) Submarine Warfare: Today and Tomorrow (1986);[6] and The Impact of Polaris (1999).
