Patrick A. Moore joined the Royal Navy in 1963 and graduated with a BSc in Electrical Engineering before going to sea as a Weapons Engineer Officer in HMS Ajax. He left the Royal Navy as a Commander in 1992, after service as the Weapons Engineer Officer in HM Ships Falmouth and Newcastle and as the Squadron Weapons Engineer Officer for the 5th Destroyer Squadron during the First Gulf War. He then worked for Ferranti International, GEC Marconi and BAE Systems, focusing on warship combat system simulators. His involvement with the Operational, Research and Development, Shipbuilding and Training functions of the RN therefore spans an impressive 42 years. Few others are better qualified to tell this story.
