To date all new
construction submarines had been large and of considerable
endurance for use in the Far East. It was clear that there was a
case for a smaller type of patrol submarine for use in European
waters in war and to replace the H-class for anti-submarine training
in peacetime. The result was the S-class which were the same size
as the first world war E-class which had proved very successful.
The S-class were re-designed, however, to carry the six 21"
bow torpedo salvo and with a slightly increased diving depth and,
like the E class, to have internal fuel.
