The long-range "Fletcher"-class ships performed every task asked of a destroyer, from anti-submarine warfare and anti-aircraft warfare to surface action. They could cover the vast distances required by fleet actions in the Pacific and served almost exclusively in the Pacific Theater of Operations during World War II, during which they accounted for 29 Imperial Japanese Navy submarines sunk. In a massive effort, the "Fletcher"s were built by shipyards across the United States and, after World War II ended, 11 were sold to countries that they had been built to fight against: Italy, Germany, and Japan, as well as other countries, where they had even longer, distinguished careers. Three have been preserved as museum ships in the U.S. and one in Greece.
