14 in Japanese battlecruiser Kongo as delivered by her British builders whilst on trials in 1912: her design was so influential that the construction of battlecruiser HMS Tiger was halted to emulate Kongo's armament layout. Reconstructed as fast battleships in the 1930s, this class served into WW2, Kongo being sunk by a US submarine in 1944.
Japanese heavy cruiser Myoko - 10 x 8 in guns, 'Long Lance' torpedo armament, 36 knots: she and her sisters were formidable opponents. Severely damaged by a US submarine after eventful service in December 1944, she was surrendered in a crippled state at Singapore at the end of the war.
USS Archerfish (SS-311) had the most successful single patrol in terms of tonnage sunk by any US submarine in WWII 59,000 tons. That's impressive when you consider that Archerfish only sank one ship in her career. That ship though was the Japanese carrier Shinano on 29 November 1944. Shinano is the largest warship ever sunk by a submarine.
USS Gato SS-212. The United States Navy Gato-class submarines were launched 1941–43 and were the first mass-production US submarine class of World War II (73 boats).Together with their near-sisters the Balao (131 boats) and Tench (30 boats) classes, their design formed the majority of the United States Navy's World War II submarine fleet.
