Information:  - A guided-missile destroyer is a destroyer designed to launch guided missiles. Many are also equipped to carry out anti-submarine, anti-air, and anti-surface operations. The NATO standard designation for these vessels is DDG. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing, or dropping it altogether. The U.S. Navy has adopted the classification DDG in the American hull classification system.  - The 18 Forrest Sherman - class destroyers were the first US post-war destroyers ( DD - 927 to DD - 930 were completed as destroyer leaders ) . Commissioned beginning in 1953 , these ships served until the late 1980s . Their weaponry underwent considerable modification during their years of service . Four were converted to guided missile destroyers . This class also served as the basis for the Charles F. Adams - class guided missile destroyer . Three ships of the class have become museum ships , nine have been sunk in training exercises , and the others have been scrapped or are scheduled to be scrapped .  - The Russo-Japanese War (8 February 1904  5 September 1905) was fought between the Russian Empire and the Empire of Japan over rival imperial ambitions in Manchuria and Korea. The major theatres of operations were the Liaodong Peninsula and Mukden in Southern Manchuria and the seas around Korea, Japan and the Yellow Sea.  - In naval terminology, a destroyer is a fast, maneuverable long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against smaller powerful short-range attackers. They were originally developed in the late 19th century as a defence against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBD) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats." Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War.  - Destroyer Leader (DL) was the United States Navy designation for large destroyers from 9 February 1951 through the early years of the cold war. United States ships with hull classification symbol DL were officially frigates from 1 January 1955 until 1975. The smaller destroyer leaders were reclassified as destroyers and the larger as cruisers by the United States Navy 1975 ship reclassification; so destroyer escorts could be reclassified as frigates (FF) in conformance with international usage of the term. Background. By the end of World War I the destroyers intended to screen formations of battleships had evolved to a displacement of approximately 1100 tons armed with four guns and six or more torpedoes. Italy had built three "esploratori" (scout cruisers) approximately 70% larger than contemporary destroyers. The Washington Naval Treaty encouraged United Kingdom satisfaction with its traditional fleet of s and United States contentment with similar and s, while the signatories with smaller fleets explored alternative warship configurations between the classical definitions of destroyer and cruiser. Italy launched three more "esploratori" and France responded with six "Chacal"-class "contre-torpilleur" super destroyers. Japan launched the minimum light cruiser followed by the "Fubuki"-class special type destroyers with endurance to escort the "Kido Butai" mobile force of aircraft carriers over the wide reaches of the Pacific.  - In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of "pendant number", which it was called before 1948). Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship.     Given the paragraphs above, decide what entity has the relation 'operator' with 'united states navy'.
