Submarine Types Page. There are links from each submarine class page to individual submarines. Submarines by Name. This link takes you to the submarine index which I have grouped by class rather than alphabetically or numerically in the hope of making it easier, if this is not so, ideas appreciated. Within these pages the Pennant numbers which have been allocated to the submarine throughout its lifespan are shown, who built the submarine and what class it belonged to.
First column gives the total number of crew including officers.
Second column gives a breakdown of crew and officers. Second column, the depot ship which they were based on and the place or in the case of no depot ship the port. Beneath this if known, a brief history of what they achieved during their lifespan. It should be noted that in the early days of the submarine service the officers and crew members were posted to the Depot ship or base which the boats were attached to. As the service became more experienced and the boats built with accommodation they were posted to the boats, but where ever possible accommodated either on the depot ships or shore establishments.
