I've founds this interesting design on the Shipbucket forums and I've thought I share it here as well.
During the Fourth Defense Force Development Plan (years 1972 – 1976), the Japan Maritime Self-Defense Force (JMSDF) planned to introduce a successor to the Yamagumo – class destroyers. This new class was to be based on the preceding Yamagumo – class, however it would feature increased displacement and the introduction of several technologies which were new to the JMSDF, such as gas turbines and a point-defense missile system.
Originally, three vessels were planned to be built from 1974 to 1976, however, due to the oil shocks arising from the 1973 Yom Kippur war and the OPEC embargo that followed, it became impossible for the Japan Defense Agency to fund the project. Ultimately, a sixth Yamagumo – class vessel would be built instead using the same intended hull number (DD-121 Yūgumo) as the first of the 2500-ton class.
It was not all in vain however, as many of the innovations that arose during the development of this type were subsequently introduced on the Hatsuyuki – class destroyers and Ishikari – class destroyer escort during the next Defense Force Development Plan. Both types were equipped with Olympus TM3B gas turbine engine that was planned to be adopted on the 2500-ton type. Thus, the 2500-ton type can be seen as a developmental “bridge” between the Yamagumo and Hatsuyuki – class destroyers even though they were never introduced into service.
