Lead ship of a class of eight, laid down between 1926 and 1929, these (admittedly overweight) Washington Treaty cruisers served the Californian navy throughout the Pacific War, heavily engaged on all fronts from the declaration of war on behalf of the Allied Powers until Japan's negotiated surrender. Mounting eight 20cm guns in four two-gun turrets, they were 'average' cruisers, and treaty-busting gained the Californians little, much of the weight being taken up in a 'conventional' protective scheme, in comparison to the various ingenious methods used by other powers.
