あさひ型護衛艦はなぜ2隻の建造で終了したのか？

The reason only two Asahi-class destroyers (the second generation), "Asahi" and "Shiranui," were built is because the plan from the beginning was for them to serve as pinch hitters. "There is a strict rule (quota) that a destroyer flotilla must be equipped with 20 general-purpose destroyers (DDs). At the time, the older Hatsuyuki-class destroyers, built in the Showa era, were reaching the end of their service life (retirement), and if this continued, there would be a gap in the 20-ship quota. Therefore, following the previous Akizuki-class (4 ships), the Asahi-class was planned and built specifically to fill the remaining two gaps. Once the two ships entered service, the 20-ship system was successfully completed, eliminating the need to build any more."
