The class was named after villages and small towns in Great Britain. Six of the class, Clovelly, Ilchester, Instow, Invergordon, Ironbridge and Ixworth were equipped to act as diving tenders. Lydford was originally commissioned as A510 Loyal Governor, then renamed P252 Alert for service in Ulster until 1986. Ships in class References Royal Maritime Auxiliary Service Ships of the Royal Navy
