In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were originally conceived in 1885 by Fernando Villaamil for the Spanish Navy as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) 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.
A motor torpedo boat is a fast torpedo boat, especially of the mid 20th century. The motor in the designation originally referred to their use of petrol engines, typically marinised aircraft engines or their derivatives, which distinguished them from other naval craft of the era, including other torpedo boats, that used steam turbines or reciprocating steam engines. Later, diesel-powered torpedo boats appeared, in turn or retroactively referred to as "motor torpedo boats" for their internal combustion engines, as distinct from steam powered reciprocating or turbine propulsion.
An aviso was originally a kind of dispatch boat or "advice boat", carrying orders before the development of effective remote communication.
The Type 053 is a family of Chinese frigates that served with the People's Liberation Army Navy Surface Force, and a small number of foreign navies.
The 3-inch/50-caliber gun in United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 50 calibers long. Different guns of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1900 through to 1990 on a variety of combatant and transport ship classes.
The Type 206 class gunboat is a gunboat of the People's Republic of China's People's Liberation Army Navy. Also known as the Huludao class, it is a simplified version of the Type 037 class submarine chaser. Used for patrol duties, it has slightly reduced displacement, but an enlarged superstructure.
The Type 037 corvette is a series 400–500 ton corvette type classes in service with the People's Liberation Army Navy. Unlike western navies, the People's Liberation Army Navy does not have dedicated patrol boats in its inventory. Instead, a large variety of corvette type classes, in the form of missile boats and submarine chasers fulfill the tasks of patrolling China's territorial waters. The Egyptian Navy operates eight vessels.
The Mornar class consisted of two large patrol boats built for the Yugoslav Navy by the Tito's Shipyard in Kraljevica during the late 1950s and early 1960s. The boats were based on the Udarnik (PBR-581), a French-built Le Fougueux-class submarine chaser acquired in 1956. Both boats had an uneventful career and were deleted in 1992.
The PCE-842-class patrol craft escort was a United States Navy (USN) ship class of submarine chasers designed during World War II. The PCE-842-class was the only class ever designated by the USN as the "patrol craft escort" (PCE) type. The PCE design was derived from the 180-foot (55 m) Admirable-class minesweeper to complement the 173-foot (53 m) PC-461-class submarine chasers that were used for anti-submarine warfare (ASW) in coastal areas. At 185 feet long and 640 tons, the PCE is more than twice the displacement of the PC but with a less powerful engine also much slower; however, because of its larger size, the PCE was able to undertake longer-range tasks over PC-461-class vessels. The USN envisaged the PCE as enabling PCs and smaller vessels to undertake coastal patrols without being called-upon as often to perform open ocean and convoy escort duties, while simultaneously freeing-up some larger vessels - such as destroyer escorts and destroyers - from convoy ASW duties. The PCE-482-class had a standard crew complement of 99 officers and men. The class would ultimately see 68 total vessels built, serving with multiple navies around the world.
Type 912 degaussing/deperming ship (ADG) is a type of little known auxiliary ships built in the People's Republic of China (PRC) for the People's Liberation Army Navy (PLAN), and this class has several derivatives. As of 2022, Type 912 is the most numerous degaussing/deperming ship in PLAN, and the longest serving degaussing/deperming ships in PLAN, until its successor ype 911 finally begun to appear in early 2010s.
Type 904 general stores issue ship and its successors Type 904A and Type 904B are second generation general stores issue ships currently in service with the People's Liberation Army Navy (PLAN). A total of five units have been built and as of mid 2015, two Type 904 ships, one Type 904A, and two Type 904B.
Type 946 submarine rescue ship with NATO reporting name Dazhou class is a type of coastal submarine rescue ship developed by China for the People's Liberation Army Navy (PLAN). A development designated as Type 946A is also in service with PLAN.
Type 52 gunboat was a type of gunboat developed by China for the People's Liberation Army Navy (PLAN) in the early 1950s, and it was the first indigenously developed gunboat in the People's Republic of China (PRC) that entered mass production
