Vickers and Barrow are names synonymous with the development of the submarine. Hundreds of submarines covering virtually every class have been built for the Royal Navy and foreign Navies. This site is dedicated to not only to those who have served on Her Majesty's Submarines but also to those employees past and present whose skills and efforts have given pride to the phrase 'Barrow built' and made the name Vickers known and respected throughout the world.
