carry large quantities of fuel, ammunition, and supplies as needed to conduct operations across the vast Pacific Ocean. The U.S. Navy resumed destroyer construction in 1932 with the . For the next seven years, the United States Navy constructed "1500 tonners", or "goldplaters". The goldplaters earned this name because of the "over–lavish facilities", which drew comment from seasoned destroyermen. The armament of the Farragut and Mahan class destroyers initially included five 5 inch dual purpose guns, a number later reduced to four due to stability problems and a desire for a larger torpedo armament. With the introduction of the dual purpose main guns, destroyers acquired an anti-aircraft mission. The 1500-ton , , , , and classes, the 1570-ton , and the 1850-ton and destroyer leaders were all laid down in quick succession following the original goldplaters. The and es were similar in design to the Sims class, but had two stacks and a "split" or echeloned powerplant for extra endurance against torpedo attacks. World War II On 7 December 1941, the day the United States entered World War II, the United States Navy had 100 destroyers seven years old or newer. This number included 27 and destroyers. However, none were equipped with torpedoes comparable to the (then unknown) Type 93 torpedoes ("Long Lance torpedo") of the Imperial Japanese Navy, and only destroyer leaders had more than four main guns—inferior to the six guns on a Japanese destroyer (the first 24 ships of the Benson/Gleaves class were built with five guns, but excessive topweight led to one being removed). In 1940, fifty "flush deckers" were transferred to the British Royal Navy and the Royal Canadian Navy under the Destroyers for Bases Agreement. Other "flush deckers" were converted as high speed transports (APD), seaplane tenders (AVD), minelayers (DM), minesweepers (DMS), and other roles (AG), while some were retained as destroyers. Most remaining in US service were rearmed with varying numbers of 3 inch dual purpose guns. After the 1500 ton limit on destroyers was changed to a 3000 ton limit with the Second London Naval Treaty, the United States Navy began sketches for a five-gun ship— on an enlarged hull. Introduced in 1942, the 175 "2100 tonners". became the U.S. Navy's signature destroyer in the Pacific War. By the end of World War II, the U.S. Navy had also commissioned 112 six-gun destroyers derived from the Fletcher design; 67 2200 tonners and
