Akizuki and Fletcher destroyers: design and numbers

How good were the Akizuki-class destroyers compared with the Fletcher class?

An Akizuki might compare favorably one-for-one, but only twelve entered service against 175 Fletchers, making American scale and utility decisive.

The Akizuki was roughly 700 tons heavier at standard displacement than the Fletcher and might compare favourably in a one-to-one encounter. About 32 were planned, but only twelve entered service and six were lost. The Japanese class carried dual-purpose guns, torpedoes, depth charges and an expanding light anti-aircraft battery. Its intended role was to escort carrier groups, deter cruisers and defend against aircraft. The Fletcher was a broadly useful destroyer available in vastly greater numbers, with 175 completed. The final judgment is that Akizuki's potential individual advantage was insufficient for the numbers it had to face.
