O’Kane conducted a total of five war patrols on the USS Tang, sinking 33 Japanese ships. This is the highest amount for any single submarine and the most for any commanding officer. O’Kane earned a reputation for being an innovator and developing unique tactics that increased the expected effectiveness of his submarine.
