The Clyde submarine base was officially commissioned in 1967. The Faslane site had originally been used as a military port during the Second World War and was built and manned by the army. HMS Adamant, the Depot ship of the 3rd Submarine Squadron, first anchored in Faslane Bay in 1957, and over the years the base has increased in size to accommodate the growing sophistication of the squadron submarines and the increasing number of hulls. This book traces the development of the base in unsurpassed pictorial detail, from its initial use by the army to October 1996, when the base became HM Naval Base Clyde. Chronicling the histories of the two submarine squadrons based at Faslane, the 3rd and 10th Squadrons, this collection is sure to provoke nostalgia among submariners and personnel who have served at the base, while providing a fascinating insight for those not so familiar with its story.
