Ondatra-class Landing Craft
The Ondatra class Soviet designation Project 1176 ''Akula'' ("shark") is a class of landing craft built for the Soviet Navy and Russian Navy between 1971 and 2009. Construction The vessels were built by the Azovskiy Shipyard, Rybinsk Shipyard and Vladivostok Shipyard. Over 40 vessels of this type were built for service with the Soviet and Russian navies, and additional vessels were built for export. The vessels are designated as type DKA ''Desantanyy Kater'' and are similar in type to the US Navy Landing Craft Mechanized (LCM). The Ondatra landing craft have a limited range (2-day, ) and have a shallow draught that make them ideal for amphibious operations and littoral combat. The carries one Ondatra for use as a tug for its air-cushioned landing craft. Although still under construction in 2009, the Project 1176 is a 1970s design that is reaching the end of its operational life. The class may be replaced by the newer Project 21820 that is currently entering service in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tugboat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightness ...

Cold War Naval Ships Of The Soviet Union
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Mariupol
Mariupol (, ; uk, Маріу́поль ; russian: Мариу́поль) is a city in Donetsk Oblast, Ukraine. It is situated on the northern coast (Pryazovia) of the Sea of Azov, at the mouth of the Kalmius River. Prior to the 2022 Russian invasion of Ukraine, it was the tenth-largest city in the country and the second-largest city in Donetsk Oblast, with an estimated population of 425,681 people in January 2022. However, Mariupol has been militarily controlled by Russia since May 2022, and the city's residents are now estimated to number around 100,000, according to Ukrainian authorities. Historically, the city of Mariupol was a centre for trade and manufacturing, and played a key role in the development of higher education and many businesses while also serving as a coastal resort on the Black Sea. From 1948 to 1989, the city was known as Zhdanov, named after Andrei Zhdanov, a high-ranking official of the Communist Party of the Soviet Union; the name was part of a larger ef ...

The headquarters of the Ukrainian Naval Forces was, until the 2014 Crimean crisis, located at Sevastopol in Crimea. The naval forces were highly affected by the Crimean crisis, as the majority of their units were stationed there. Ships that did not escape or were not deployed at the time lowered their flags and were interned. Russia began a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georgian Navy
The Georgian Coast Guard ( ka, საქართველოს სანაპირო დაცვა) is the maritime arm of the Georgian Border Police, within the Ministry for Internal Affairs. It is responsible for the maritime protection of the entire coastline of Georgia, as well as the Georgian territorial waters. The primary missions of the service are administration of the territorial waters, marine pollution protection, maritime law enforcement, search and rescue, port security and maritime defense. The former Georgian Navy was absorbed into the Coast Guard in 2009. The Georgian Navy (Georgian Naval Forces; ka, საქართველოს სამხედრო საზღვაო ძალები, ) was a branch of the Georgian Defense Ministry armed forces until 2009, when it was merged with the Coast Guard and transferred to the Ministry for Internal Affairs.

Main Battle Tanks
A main battle tank (MBT), also known as a battle tank or universal tank, is a tank that fills the role of armor-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter-weight composite armor allowed the design of a tank that had the firepower of a super-heavy tank, the armor protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. Through the 1960s and 1970s, the MBT replaced almost all other types of tanks, leaving only some specialist roles to be filled by lighter designs or other types of armored fighting vehicles. Main battle tanks are a key component of modern armies. House (1984), ''Toward Combined Arms Warfare: A Survey of 20th-Century Tactics, Doctrine, and Organization'' Modern MBTs seldom operate alone, as they are organized into armoured units that include the support of infantry, who may accompany the tanks in infantry figh ...

Air-cushioned Landing Craft
An air-cushioned landing craft, also called an LCAC ( landing craft, air cushioned), is a modern variation on the amphibious landing boat. The majority of these craft are small- to mid-sized multi-purpose hovercraft, also known as "over the beach" ("OTB") craft. This allows troops and material to access more than 70 percent of the world's coastline, while only approximately 15 percent of that coastline is available to conventional boat-type landing craft. Typical barriers to conventional landing craft are soft sandy beaches, marshes, swampland, and loose surfaces. Air cushion technology has vastly increased the landing capability of the craft, providing greater speed and flexibility over traditional landing craft. Like the mechanized landing craft, they are usually equipped with mounted machine guns; they also support grenade launchers and heavy weapons. Types * Aist-class LCAC (Soviet tank-carrying hovercraft) * Griffon-GRSE 8000 TD-Class Hovercraft * Gus class LCAC * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Littoral (military)
In military and naval warfare, littoral warfare is operations in and around the littoral zone, within a certain distance of shore, including surveillance, mine-clearing and support for landing operations and other types of combat shifting from water to ground, and back. Definition Littoral warfare is warfare in and around the littoral zone. History Littoral warfare has been conducted almost as long as human societies have been conducting warfare. In the 21st century the United States Marine Corps re-emphasized littoral warfare. See also * Amphibious warfare * Littoral combat ship The littoral combat ship (LCS) is either of two classes of relatively small surface vessels designed for operations near shore by the United States Navy. It was "envisioned to be a networked, agile, stealthy surface combatant capable of defeat ... References Combat {{mil-stub ...

Landing Craft
Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force (infantry and vehicles) from the sea to the shore during an amphibious assault. The term excludes landing ships, which are larger. Production of landing craft peaked during World War II, with a significant number of different designs produced in large quantities by the United Kingdom and United States. Because of the need to run up onto a suitable beach, World War II landing craft were flat-bottomed, and many designs had a flat front, often with a lowerable ramp, rather than a normal bow. This made them difficult to control and very uncomfortable in rough seas. The control point (too rudimentary to call a bridge on LCA and similar craft) was normally at the extreme rear of the vessel, as were the engines. In all cases, they were known by an abbreviation derived from the official name rather than by the full title. History In the days of sail, the ship's boats were us ...
