Matka-class Missile Boat
The Matka class is the NATO reporting name for a group of hydrofoil missile boats built for the Soviet Navy (Baltic Fleet and Black Sea Fleet). The Soviet designation was Project 206MR Vikhr. Following the 1997 Black Sea Fleet partition treaty all Black Sea Fleet Matka class boats were passed to the Ukrainian Navy but the last vessel of the class was allegedly captured by Russia during its invasion of Ukraine in 2022. Design These boats are the descendants of the and are a heavily modified version of the . There is only a single foil, the aft part of the hull hydroplanes at high speeds. They are air-conditioned and NBC-sealed. The SS-N-2 launchers are the same type as carried on the Project 61MR ("Mod-Kashin")-class destroyers. Despite initial reports that they were good seaboats, later information revealed that the Soviets regarded them as cramped inside and top-heavy. Of thirteen planned ships, one was cancelled and another started but never completed. All were built in L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrofoil
A hydrofoil is a lifting surface, or foil, that operates in water. They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds. Description The hydrofoil usually consists of a winglike structure mounted on struts below the hull, or across the keels of a catamaran in a variety of boats (see illustration). As a hydrofoil-equipped watercraft increases in speed, the hydrofoil elements below the hull(s) develop enough lift to raise the hull out of the water, which greatly reduces hull drag. This provides a corresponding increase in speed and fuel efficiency. Wider adoption of hydrofoils is prevented by the increased complexity of building and maintaining them. Hydrofoils are generally prohibitively more expensive than conventional watercraft above a certain disp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CIWS
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Examples of g ...

Engels, Saratov Oblast
Engels ( rus, Э́нгельс, p=ˈɛnɡʲɪlʲs), formerly known as Pokrovsk and Kosakenstadt, is a city in Saratov Oblast, Russia. It is a port located on the Volga River across from Saratov, the administrative center of the oblast, and is connected to it with a bridge. It is the second-largest city in Saratov Oblast with a population of . Historically an important center for Volga Germans, the city was known jointly as Pokrovsk in Russian and as Kosakenstadt in German, until it was renamed after Friedrich Engels in 1931. Engels served as the capital of the Volga German Autonomous Soviet Socialist Republic from 1918 to 1941. It was previously known as ''Pokrovska sloboda'' (until 1914), ''Pokrovsk'' (until 1931). History Engels was founded as a sloboda named Pokrovska Sloboda by Ukrainian Chumak settlers in 1747. During the reign of Catherine the Great, ethnic Germans were encouraged to settle in the Volga region and many moved into the town, making it a major center of the ...

Komar Class Missile Boat
The Soviet Project 183R class, more commonly known as the Komar class, its NATO reporting name, meaning "mosquito", is a class of missile boats, the first of its kind, built in the 1950s and 1960s. Notably, they were the first to sink another ship with anti-ship missiles in 1967. Design The Project 183 motor torpedo boat (MTB) was designed just after World War II. These boats were armed with two torpedo tubes and were used extensively by Soviet coastal forces in the 1950s. The torpedo boat had a wooden semi-planing hull and was fitted with radar. Over 622 MTBs were built. A submarine chaser variant fitted with sonar and depth charges was also built as was a radio-controlled target boat. In 1956, the P-15 Termit missile became available (NATO reporting name: SS-N-2 "Styx"). The Project 183 proved to be a natural choice for mounting the new missiles, giving the small, fast boats great firepower for their size. The new combination was designated Project 183R (R apparently for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osa Class Missile Boat
The Project 205 Moskit (''mosquito'') more commonly known by their NATO reporting name Osa, are a class of missile boats developed for the Soviet Navy in the late 1950s. Until 1962 this was classified as a large torpedo boat. The Osa class is probably the most numerous class of missile boats ever built, with over 400 vessels constructed between 1960 and 1973 for both the Soviet Navy and for export to allied countries. "Osa" means "wasp" in Russian, but it is not an official name. The boats were designated as "large missile cutters" in the Soviet Navy. Origins While the earlier Komar class were cheap and efficient boats (and the first to sink a warship with guided missiles, destroying the Israeli Navy's '' Eilat''), their endurance, sea keeping, and habitability were modest at best, and the missile box was vulnerable to damage from waves. Among their other weak points were the wooden hull, the radar set lacking a fire control unit, and an inadequate defensive armament consisti ...

Queen (insect)
The gyne (, from Greek γυνή, "woman") is the primary reproductive female caste of social insects (especially ants, wasps, and bees of order Hymenoptera, as well as termites). Gynes are those destined to become queens, whereas female workers are typically barren and cannot become queens. Having a queen is what makes a "queenright" hive, nest, or colony of eusocial insects. A colony with multiple queens is said to be a polygyne form, whereas one with only one is a monogyne form. The red imported fire ant is known to have colonies in both polygyne and monogyne forms. The small red ant, ''Leptothorax acervorum'', has colonies that switch from monogyny to polygyny as a result of seasonal fluctuations. The little fire ant ''Wasmannia auropunctata'' produces unique kinds of meiotic oocytes with a drastic reduction in recombination. These oocytes may either fuse together for gyne production ( automictic parthenogenesis with central fusion) or be fertilized by male gametes for the ...

Uterus
The uterus (from Latin ''uterus'', plural ''uteri'') or womb () is the organ in the reproductive system of most female mammals, including humans that accommodates the embryonic and fetal development of one or more embryos until birth. The uterus is a hormone-responsive sex organ that contains glands in its lining that secrete uterine milk for embryonic nourishment. In the human, the lower end of the uterus, is a narrow part known as the isthmus that connects to the cervix, leading to the vagina. The upper end, the body of the uterus, is connected to the fallopian tubes, at the uterine horns, and the rounded part above the openings to the fallopian tubes is the fundus. The connection of the uterine cavity with a fallopian tube is called the uterotubal junction. The fertilized egg is carried to the uterus along the fallopian tube. It will have divided on its journey to form a blastocyst that will implant itself into the lining of the uterus – the endometrium, where it will ...

Russian Airborne Troops
The Russian Airborne Forces (russian: Воздушно-десантные войска России, ВДВ, Vozdushno-desantnye voyska Rossii, VDV) are the airborne forces branch of the Russian Armed Forces. It was formed in 1992 from units of the Soviet Airborne Forces that came under Russian control following the dissolution of the Soviet Union. Troops of the Russian Airborne Forces have traditionally worn a blue beret and blue-striped ''telnyashka'' undershirt and are called ''desant'' (Russian: Десант) from the French ''Descente''. The Russian Airborne Forces utilizes a range of specialist airborne warfare vehicles and are fully mechanized. They traditionally have a larger complement of heavy weaponry than most contemporary airborne forces. History With the demise of the Soviet Union, the number of VDV divisions shrank from seven to four, as well as four brigades and the brigade-sized training center. In October 2013, Shamanov announced that a new air assault brig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poti
Poti ( ka, ფოთი ; Mingrelian: ფუთი; Laz: ჶაში/Faşi or ფაში/Paşi) is a port city in Georgia, located on the eastern Black Sea coast in the region of Samegrelo-Zemo Svaneti in the west of the country. Built near the site of the ancient Greek colony of Phasis and deriving its name from the same, the city has become a major port city and industrial center since the early 20th century. It is also home to a main naval base and the headquarters of the Georgian Navy. Etymology The name Poti is linked to Phasis, but the etymology is a matter of a scholarly dispute. "Phasis" () is first recorded in Hesiod's ''Theogony'' (c. 700 BC) as a name of the river, not a town. Since Erich Diehl, 1938, first suggested a non-Hellenic origin of the name and asserted that Phasis might have been a derivative of a local hydronym, several explanations have been proposed, linking the name to the Proto-Georgian-Zan ''*Poti'', Svan ''*Pasid'', and even to a Semitic word, ...
