Only partly true.I agree with a lot of the above but the only observation I have is that during the war I understand that the British 8in cruisers lost their torpedo's to give the weight to AA guns, directors and Radars.
When the RN Kent class were modernised in the late 1930s they lost their TT. Given the requirement to remain within Treaty displacement limits choices had to be made about what was kept, removed or added. In this case the view was taken that, as these ships were then more likely to be operating on the shipping lanes not as part of the main fleet, aircraft facilities were more important than TT so the latter were removed and the former upgraded. That represented a change in the way the RN envisaged using these ships between their original design and the mid-1930s. Australia also lost hers at this time but Canberra retained hers until sunk.
The other County classes plus Exeter & York on the whole retained theirs. An exception was Sussex which did lose hers and X turret to gain more AA in a 1944/45 refit.
Generally the RN preferred to sacrifice gun power rather than torpedo power in its cruisers. So later classes, with only a couple of exceptions, retained their TT into the post WW2 period. RN cruiser designs in the 1944-47 period increased the TT armament to 4 quad mounts, but none of these were built.
