Within the assault formation, there were 6 "Nanzhu Sea" class vessels, along with 12 ten-thousand-ton cruisers and at least 20 large destroyers.
All of these were newly built warships constructed after the outbreak of the great war.
Although out of habit, people still used the term "heavy cruiser," the fact was that the warships built after the outbreak of the war were no longer heavy cruisers.
The reason was quite simple.
The concept of "heavy cruiser" itself originated from two naval arms treaties, specifically referring to cruisers equipped with 8-inch main guns. In contrast, light cruisers were equipped with 6-inch main guns. As for other specifications like tonnage, there was no special distinction between the two types of cruisers.
After the treaties were voided, the concept of heavy cruisers ceased to exist.
Precisely for this reason, those built after the treaties were voided were generally referred to as post-treaty types.
