That's a cool name for a ship!
Built as part of the effort to assemble a major submarine force just prior to and after the U.S. entry into World War II, USS Croaker was sent into the Pacific to wage a war of attrition against Japan's merchant marine and Navy. Croaker made six war patrols, and attacked and sank a cruiser, four tankers, two freighters, an ammunition ship, two escort craft, and a minesweeper. Credited with eleven sinkings, with a total of 40,000 tons, Croaker's war career typifies the tremendous success of the submarine war against Japan.
I think Croaker was a cool name.
