Sadly, the "Tank" ceased to be used, even on a reduced basis, by the Submarine Service in 2020, but it was kids' stuff compared with being first out doing a voluntary run from 300 feet when exercising with the "Swim Boys" off the West Coast of Scotland! A very deep pool indeed, and no restraints there like in the Tank.....
