Why the Royal Navy removed cruiser torpedoes after 1945

Why were the Crown Colony cruisers' torpedo tubes removed after the war?

Officials cited few immediate surface threats, compressed-air hazards, cost savings, and smaller crews.

Immediately after the war, the major cruiser and battleship fleets were treated as allies, leaving few apparent opponents to justify cruiser torpedoes. Torpedoes also carried compressed-air risks. Removing them could save money and reduce crews when politicians were demanding economies. The Sverdlovs arrived late enough for earlier torpedo removals to have been justified on economy and risk. The Royal Navy later used the Soviet cruisers to argue for retaining more British cruisers and Vanguard, without much political support. Although the Soviet threat complicated the justification for removal, the case used remained that too few targets warranted retaining the weapons.
