The most successful American submarine in history. Under CDR Richard O'Kane — former XO of Wahoo — Tang sank 33 ships for 116,454 tons in just five patrols. On her final patrol she sank 13 ships before her last torpedo made a circular run and struck her own stern. O'Kane received the Medal of Honor. Nine of 87 crew survived using Momsen lungs — the only successful escape from a sunken submarine in WWII.

Lost the same day as Tang. Depth charged by Japanese escorts while attacking a convoy in the Luzon Strait on October 24, 1944. One of the convoy's ships, the Arisan Maru, was carrying 1,781 American POWs — only 9 survived. Whether Shark's torpedoes struck the Arisan Maru remains debated. All 87 hands lost.
