When I first saw the title of this thread I drew a blank. I knew there was some naval action in Korea, and for sure there was a lot of gunnery and carrier support for the troops on land and interdiction of supplies. But naval battles? As in BATTLE? I drew a blank.
So I researched it and discovered there was only one actual battle, and thats if you can call shooting up a bunch of torpedo boats by capitol ships a "battle". Anyway, heres the page

Save the link because its a gem of a research web sight. I always tell people we already have a time machine that can predict the future. Its called, "The study of history".
