Unofficially named Sandra
Less elaborately equipped as previous boats as they were intended for training. In May 1946 two midget submarines were moored at the low-water mark in Aberlady Bay. It is believed that these craft were XT1 and XT2, two examples of a training version of the British X craft midget submarines.
The two XT class vessels moored in Aberlady Bay were used for trials by de Havilland Mosquito aircraft based at R.A.F. East Fortune, now the Museum of Flight, part of the National Museums of Scotland. These aircraft were used to train R.A.F. crew for Coastal Command anti-shipping strike squadrons and they used the two XT craft to test the effectiveness of cannon shells in piercing the armour plate of the midget submarines. The remains of the midget submarines can still be seen at low tide.

Fort Blockhouse had its beginnings as a military base in 1431 when Henry VI authorised a tower to be built on the Gosport side of Portsmouth Harbour. The Navy moved into Fort Blockhouse in 1905 for the purpose of establishing a Submarine Boat Station.
This fascinating series from HISTORY™ will explore the world of the US Navy Submariner in World War II.
We'll dive deep to periscope depth in the Pacific and hunt a convoy of Japanese freighters, surface in the Atlantic and fire upon a stricken German U-Boat, sneak into Tokyo Bay and wreck havoc upon the Japanese Fleet and learn about the men who lived and hunted under the sea, while discussing the different submarines and their use in war.
Plus we'll explore the tactics used to destroy the enemy and how submarines contributed to the final defeat of Imperial Japan and Nazi Germany.
Take a journey beneath the waves and discover the incredible story behind The Submarines of World War II: The Silent Service.
Over six hours of footage across four discs tell the fascinating stories of the submarines of World War II.
