The original 15 foot tank was built in 1930 at HMS Dolphin, Gosport.
In the Royal Navy DSEA training began at this time, every officer and rating on joining submarines was immediately given a two day course
before he was allowed to go to sea.
In 1941, SETT instructors were involved in training crews for Human Torpedo's, Midget Submarines and Frogmen.
In 1946 Captain Philip Ruck Keene was appointed as chairman of a committee which was to investigate and report on the efficiency and deficiencies
of the escape arrangements built into the submarines of the Royal Navy.
It was as a result of Ruck Keene's committee, that numerous shortfalls were identified and recommendations were made that enabled Submarine Escape
and Rescue training and developement of equipment to progress to the present day.
The present Submarine Escape Training Tank was built in 1953 and commisioned in 1954.
