Heiwa Maru

The Heiwa Maru was a whaling ship of Japanese origin that the Diamond Dogs utilized.

Because the International Whaling Commission "raised a stink" against whaling, Japan's whaling industry suffered, with Diamond Dogs during the nine years Big Boss and Venom Snake were in a coma purchasing it at a cheap price. The ship was later put to use to deliver Venom Snake to Port Said for a brief layover, before transferring to the oil tanker Karachi for the remaining distance to Port Qasim during the trek to Afghanistan to rescue Kazuhira Miller from Soviet forces.
