On completion of contractors trials, she returned to the Barrow shipyard to carry out trials on an early version of a pump-jet propulsion system.

All of the boats were periodically taken out of reserve, to participate in exercises. They were normally based at Portland, Dorset. The X51 Class were an improvement on the earlier classes of X-craft of World War II vintage. In the early days of the “Cold War”, Britain then having no means of delivering a nuclear weapon into the U.S.S.R., it was thought that this type of boat could be used to lay nuclear mines in Warsaw Pact dockyards and harbours. These midget submarines eventually fell victim to economic cuts, when Flag Officer submarines (F.O.S.M.) was required to reduce the number of “hulls” under his command. |
