 Ioshima-class cruiser

The also called were a pair of escort ships reconstructed from former Republic of China Navy Ning Hai class cruisers that were sunk during earlier battles- from "Ning Hai" and from "Ping Hai" - these ships were salvageable as river water doesn't corrode sunken hulls as badly as sea water would.Originally they were to be transferred to the puppet government of Wang Jing-Wei, but instead of honoring the agreement, the Japanese seized and outfitted them first as barracks hulks and ultimately to their final form in 1944.
