Oleg,
I'm actually working on creating more historical ships present in the game. I'm replacing the lil' gunboats usually with Subchasers, placing the gunboats near China and along coastlines.
Also in progress are more historical patrols such as true patrols areas during the Philippines invasion of '41, invasion of the Dutch-East Indies, patrols in the Solomons '42, blockade of Truk during late '42, patrols in the Sea of Japan early '43, etc...etc...
