Uncover the remarkable stories of the X-class submarines which played a crucial part in the success several Second World War operations, proving that size isn’t everything.

X24 is the only surviving X-class submarine in the world. Measuring only 50 feet in length, this tiny but important submarine would take on dangerous missions off Norway.

The crew of four sometimes spent up to two weeks inside the cramped environment. You have to see it to believe it!

Other X-craft played a key role in D-Day operations, conducting reconnaissance and signposting the invasion forces towards the French coast.

The D-Day landings could have gone catastrophically wrong if it weren’t for these small craft, who prepared the way for the thousands of vessels and servicemen that landed on the Normandy beaches.
