Serna-class Landing Craft
The Serna class, Russian designation Project 11770, is a class of air cavity system landing craft constructed for the Russian Navy. Twelve boats were built by Vostochnaya Verf between 1994 and 2014. Four boats of the export project 11771 were built in 1994. 4 ships of the Project 11771 designation were made specifically for export to other countries. One was sold to Estonia, and 3 were sold to the United Arab Emirates. Deployment During the 2022 Russian invasion of Ukraine On 24 February 2022, in a major escalation of the Russo-Ukrainian War, which began in 2014. The invasion has resulted in tens of thousands of deaths on both sides. It has caused Europe's largest refugee crisis since World War II. ..., a Serna-class craft docked at Snake Island was destroyed when the island was attacked by a Ukrainian Bayraktar TB2 drone on 6 May 2022.

Vostochnaya Verf
JSC Vostochnaya Verf (until 1994 - Vladivostok Shipyard) is a Russian shipbuilding enterprise located in Vladivostok. Background The enterprise was founded in 1952 for the construction of low-tonnage ships from non-magnetic materials for the needs of the Pacific Fleet and the border forces of the Far Eastern region of the USSR, such as minesweepers. In 1994, the plant was transformed into a joint stock company. From the 1950s to the 2000s, the enterprise built more than 400 ships for the Navy, border forces and fishing organizations. More than 30 units of military equipment were supplied for export to eight countries of the world (Vietnam, Cuba, China, Indonesia, Ethiopia, Guinea, Iraq, Yemen): torpedo and missile boats were built at this shipyard. According to Igor Miroshnichenko, General Director of OJSC Vostochnaya Verf, by 2010, Vostochnaya Verf in terms of production volume reached 80-85% of the production level before restructuring.

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 ...

Main Battle Tank
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.#House1984, 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 inf ...

Armoured Personnel Carrier
An armoured personnel carrier (APC) is a broad type of armoured military vehicle designed to transport personnel and equipment in combat zones. Since World War I, APCs have become a very common piece of military equipment around the world. According to the definition in the Treaty on Conventional Armed Forces in Europe, an APC is "an armoured combat vehicle which is designed and equipped to transport a combat infantry squad and which, as a rule, is armed with an integral or organic weapon of less than 20 millimetres calibre." Compared to infantry fighting vehicles (IFVs), which are also used to carry infantry into battle, APCs have less armament and are not designed to provide direct fire support in battle. Infantry units which travel in APCs are known as mechanized infantry. Some militaries also make a distinction between infantry units which use APCs and infantry units which use IFVs, with the latter being known as armoured infantry in such militaries.

Air Cavity System
Air cavity system (or ACS) is a modern marine hull design concept based upon capturing air beneath a vessel's hull to reduce drag and increase speed and fuel efficiency. How it works The system works by trapping a layer of air bubbles beneath the ship's hull. A dedicated system or an air blower generates air bubbles that pass nonstop under the ship's surface. Along the bottom of the hull, air bubble outlets are located at different sites equally on both the sides of the boat's center. A layer of bubbles is formed by blowing air at a constant rate, reducing the drag and resistance between the boat and the water. Operational use ACS is used on the Russian Serna- and Dyugon-class landing crafts. See also *Froude number *Hull (watercraft) *Ship resistance and propulsion A ship must be designed to move efficiently through the water with a minimum of external force. For thousands of years ship designers and builders of sailing vessels used rules of thumb based on the midship-sect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2022 Russian Invasion Of Ukraine
On 24 February 2022, in a major escalation of the Russo-Ukrainian War, which began in 2014. The invasion has resulted in tens of thousands of deaths on both sides. It has caused Europe's largest refugee crisis since World War II. An estimated 8 million Ukrainians were displaced within their country by late May and 7.8 million fled the country by 8 November 2022, while Russia, within five weeks of the invasion, experienced its greatest emigration since the 1917 October Revolution. Following the 2014 Ukrainian Revolution, Russia annexed Crimea, and Russian-backed paramilitaries seized part of the Donbas region of south-eastern Ukraine, which consists of Luhansk and Donetsk oblasts, sparking a regional war. In March 2021, Russia began a large military build-up along its border with Ukraine, eventually amassing up to 190,000 troops and their equipment. Despite the build-up, denials of plans to invade or attack Ukraine were issued by various Russian gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake Island (Ukraine)
Snake Island, also known as Serpent Island or Zmiinyi Island ( uk, острів Змії́ний, ostriv Zmiinyi; ro, Insula Șerpilor; russian: Змеиный, Zmeinyy), is an island belonging to Ukraine located in the Black Sea, near the Danube Delta, with an important role in delimiting Ukrainian territorial waters. The island has been known since classical antiquity, and during that era hosted a Greek temple to Achilles. Today, it is administered as part of Izmail Raion of Ukraine's Odesa Oblast. The island is populated, reported to have under 30 people in 2012. A village, Bile, was founded in February 2007 with the purpose of consolidating the status of the island as an inhabited place. This happened during the period in which the island was part of a border dispute between Romania and Ukraine from 2004 to 2009, during which Romania contested the technical definition of the island and borders around it. The territorial limits of the continental shelf around Snake Island ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bayraktar TB2
The Bayraktar TB2 is a medium-altitude long-endurance (MALE) unmanned combat aerial vehicle (UCAV) capable of remotely controlled or autonomous flight operations. It is manufactured by the Turkish company Baykar Makina Sanayi ve Ticaret A.Ş., primarily for the Turkish Armed Forces. The aircraft are monitored and controlled by an aircrew in a ground control station, including weapons employment. The development of the UAV has been largely credited to Selçuk Bayraktar, a former MIT graduate student. By November 2021, the TB2 drone had completed 400,000 flight-hours globally. The largest operator of TB2 drones is the Turkish military, but an export model has been sold to the militaries of a number of other countries. Turkey has used the drone extensively in strikes on Kurdistan Workers' Party (PKK) and People's Protection Units (YPG) targets in Iraq and Syria. Bayraktar drones were later deployed by a number of other nations around the world in various wars, such as by Azerbai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
