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.
