P 6-class Torpedo Boat
The P 6-class torpedo boat, Soviet designation Project 183 ''Bolshevik'', were Soviet wood-hulled motor torpedo boats produced shortly after World War II. They were armed with two twin 25 mm autocannons and two torpedoes. Design and development A large torpedo boat developed shortly after World War II, the Project 183 "Bolshevik" torpedo boats were influenced by the American-built Vosper, Elco, and Higgins motor torpedo boats delivered to the Soviet Union via Lend-lease. The development was carried out by the No.5 shipyard in Leningrad, and had a hull designed to be semi-planing with sharp lines, compared to the earlier full hydroplaning Soviet designs like the or Project 123-bis. The boat was made out of wood and powered by four M-50 diesel engines, and able to reach a maximum speed of . The ships were armed with two twin 25 mm autocannons with 2,000 rounds of ammunition, two 533 mm torpedo tubes, and eight depth charges. Additionally sea mines could be taken to replace th ...

Hydroplane (boat)
A hydroplane (or hydro, or ''thunderboat'') is a fast motorboat, where the hull shape is such that at speed, the weight of the boat is supported by planing forces, rather than simple buoyancy. A key aspect of hydroplanes is that they use the water they are on for lift rather than buoyancy, as well as for propulsion and steering: when travelling at high speed water is forced downwards by the bottom of the boat's hull. The water therefore exerts an equal and opposite force upwards, lifting the vast majority of the hull out of the water. This process, happening at the surface of the water, is known as ' foiling'. Hydroplane design Early designs of the 1920s were often built by amateurs, who employed the lightest materials available to them at the time, which were often glued timber boarding or plywood on the floor, plywood topsides, and varnished canvas decks. Most were about long and stepped hulls were employed with a step to induce air under the hull, to enable the boa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Turbine
A gas turbine or gas turbine engine is a type of Internal combustion engine#Continuous combustion, continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electric ...

HMS Zealous (R39)
HMS ''Zealous'' was a Z-class destroyer of the Royal Navy built in 1944 by Cammell Laird. She served during the Second World War, participating in operations in the North Sea and off the Norwegian coast, before taking part in some of the Arctic convoys. She spent a further ten years in Royal Navy service after the end of the war before being sold to the Israeli Navy, which operated her as INS ''Eilat''. She saw action during the Suez Crisis in 1956 attacking Egyptian ships, and was still active by the outbreak of the Six-Day War in 1967. She was sunk several months after the conflict by missiles launched from several small Egyptian missile boats; this made her the first vessel to be sunk by a missile boat in wartime. It was an important milestone in naval surface warfare, which aroused considerable interest around the world in the development of small manoeuvrable missile boats. Design and construction The Z-class were War Emergency Programme destroyers, intended for general ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Six-Day War
The Six-Day War, also known as the June War, 1967 Arab–Israeli War or Third Arab–Israeli War, was fought between Israel and a coalition of Arab world, Arab states, primarily United Arab Republic, Egypt, Syria, and Jordan from 5 to 10June 1967. Military hostilities broke out amid poor relations between Israel and its Arab neighbors, which had been observing the 1949 Armistice Agreements signed at the end of the 1948 Arab–Israeli War, First Arab–Israeli War. In 1956, regional tensions over the Straits of Tiran (giving access to Eilat, a port on the southeast tip of Israel) escalated in what became known as the Suez Crisis, when Israel invaded Egypt over the Israeli passage through the Suez Canal and Straits of Tiran, Egyptian closure of maritime passageways to Israeli shipping, ultimately resulting in the re-opening of the Straits of Tiran to Israel as well as the deployment of the United Nations Emergency Force (UNEF) along the Borders of Israel#Border with Egypt, Egypt ...

Shantou-class Gunboat
The ''Shantou''-class gunboat was a Chinese-built gunboat of the People's Republic of China's People's Liberation Army Navy. Known in the United States as the "Swatow" class gunboat, it was based on the Soviet P-6 class torpedo boat. The boat is designated as Type 55A (55 Jia Xing, 55甲型). Instead of being wooden hulled, and having torpedoes as the main armament, the ''Shantou'' class is steel-hulled, with guns as the main armament. The ''Shantou'' (or ''Swatow'') is the predecessor of the Type 062 gunboat, or more commonly known as the Shanghai-I & II class. Service history Entering service from 1955 through 1960, these vessels were completely removed from naval service by the mid-1990s, and were transferred to civilian law enforcement agencies. However, just like the ''Beihai'', ''Huangpu'', and ''Yulin'' class gunboats which had been transferred to law enforcement agencies, these obsolete and aging boats were not satisfactory in their new civilian roles, due largely to t ...

Submarine Chaser
A submarine chaser or subchaser is a type of small naval vessel that is specifically intended for anti-submarine warfare. They encompass designs that are now largely obsolete, but which played an important role in the wars of the first half of the 20th century. Many of the American submarine chasers used in World War I found their way to Allies (World War II), Allied nations by way of Lend-Lease in World War II. Submarine chaser variants U.S. Navy submarine chasers were designed specifically to destroy German Empire, German submarines in World War I, and Empire of Japan, Japanese and Nazi Germany, German submarines in World War II. The small SC-1-class submarine chasers of the design used in World War I carried the hull designator SC (for Submarine Chaser). Their main weapon was the depth charge. They also carried machine guns and anti-aircraft guns. The similar-sized SC-497-class submarine chaser, SC-497-class was built for World War II. Also in World War II, larger PC-461-cla ...
