In World War II, the United States Navy used submarines heavily. Overall, 263 US submarines undertook war patrols, [2] claiming 1,392 ships and 5,583,400 tons during the war. [3] [a] Submarines in the United States Navy were responsible for sinking 540,192 tons or 30% of the Japanese navy and 4,779,902 tons of shipping, or 54.6% of all Japanese shipping in the Pacific Theater.
Seventy-seven Gato-class submarines were built during World War II, commissioned from November 1941 through April 1944. [1] The class was very successful in sinking Japanese merchant ships and naval vessels: the top three US submarines in tonnage sunk were Gatos, along with three of the top seven in number of ships sunk.

The 700,000 ton target was achieved in only one month, November 1942, while after May 1943 average sinkings dropped to less than one tenth of that figure. By the end of the war, although the U-boat arm had sunk 6,000 ships totalling 21 million GRT, the Allies had built over 38 million tons of new shipping. [citation needed]

USS Tang (SS-306) was a Balao-class submarine of World War II, the first ship of the United States Navy to bear the name Tang. She was built and launched in 1943, serving until being sunk by her own torpedo off China in the Taiwan Strait on 24 October 1944. In her short career in the Pacific War, Tang sank 33 ships totalling 116,454 tons. [8]
The maximum safe diving depth of the I-400-class submarine was only 82% of its overall length, which presented problems if the submarine dived at too steep an angle in an emergency. [19] Because of their large aircraft hangars and conning tower, all I-400 -class boats had significant visual and radar signatures on the surface, and could be ...
