About: List of Gato-class submarines

List of Gato-class submarines and their dispositions. 77 of these boats were built during World War II, commissioned from November 1941 through April 1944. 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. But success had a price: 20 of the 52 US submarines lost in that war were of this class, plus Halibut, a damaged boat that returned to the US but was considered a constructive total loss and not repaired. Although many of the class were in reserve postwar and scrapped in 1959-1960, some Gatos served actively with the US Navy into the late 1960s, and others served with foreign navies into the early 1970s.
