World of Warships cruisers replace Britain's heavy cruisers

What if Britain's heavy cruisers became Gibraltar-class ships from World of Warships?

Britain gains about nineteen much more capable cruisers, improving attacks on surface raiders and fleet air defence while freeing other ships for different duties.

Replacing Britain's heavy cruisers with the fictional Gibraltar design from World of Warships would provide about nineteen ships with twelve 9.2-inch guns each. Their radar-directed 4.5-inch and 40 mm anti-aircraft weapons would also offer a substantial improvement. The scenario is applied to the opening campaigns of the Second World War, although the year in the transcribed prompt is inconsistent with that setting. German commerce raiders and Italian cruisers would face much stronger opponents, and radar would improve the chance of finding them. A comparison with Bismarck produces disagreement over how much advanced fire control could compensate for the battleship's heavier guns. Torpedo armament also requires care: Gibraltar lacks the torpedoes discussed for the related fictional Monmouth. Supplying the 4.5-inch mount could have a wider effect by allowing Britain to build destroyers resembling the later Daring arrangement.
