This site is dedicated to researching and writing about the history of the Royal Navy Submarine HMS Unshaken (P54).
For many years I have been collecting archival material and visiting the locations of some of Unshaken’s operations. I shall be producing a series of accounts of her patrols (see Publications). These will make-up an anthology:
HMS/m Unshaken (P54): An Illustrated History of a Submarine at War.
