USS Archer-Fish (SS/AGSS-311) was a Balao-class submarine. Archer-Fish is best known for sinking the Japanese Navy’s Aircraft carrier Shinano in November 1944 — the largest warship ever sunk by a submarine. For this achievement, she received a Presidential Unit Citation after World War II. She also received five battle stars during WW II.
The Silent Service comprised less then 1.6% of all US Naval personnel in the Pacific, yet accounting for more then half of all enemy shipping sunk. The final tallies show that of the 10 million tons of military and merchant shipping lost by the Japanese during WW II, US submarines accounted for a total of 54%.
