Novocherkassk (vessel)
''Novocherkassk'' (BDK-46) was a of the Russian Navy and part of the Black Sea Fleet. Named after Russian city of Novocherkassk, the ship was built in Poland and launched in 1987. The ship was attacked twice during the Russian invasion of Ukraine, being damaged in March 2022, and attacked again in December 2023. In the second attack, the Ukrainian Air Force fired cruise missiles at the ship while the ship was at a naval base in Feodosia, Crimea. While Russian officials admitted the ship was damaged, Ukrainian Air Force officials said that the ship sustained extensive damage due to secondary explosions which would make repairs difficult. The UK Ministry of Defence assessed the ship as "completely destroyed", and the UK Defence Secretary said the ship's destruction showed "Russia’s dominance in the Black Sea is now challenged." Subsequent satellite imagery and photographs attributed to Crimean observers showed that the ship suffered extensive damage and was partially submerged in ...

Novorossiysk
Novorossiysk (, ; ) is a city in Krasnodar Krai, Russia. It is one of the largest ports on the Black Sea. It is one of the few cities designated by the Soviet Union as a Hero City. The population was History In antiquity, the shores of the Tsemes Bay were the site of Bata (), an ancient Greek colony that specialized in the grain trade. It is mentioned in the works of Strabo and Ptolemy, among others. Following brief periods of Roman and Khazar control, from the 9th century onwards, the area was part of the Byzantine θέμα Χερσῶνος ''Thema Khersonos'' (Province of Cherson). During the 11th century, the area was overrun and controlled by nomads from the Eurasian steppe, led by the Cumans. Later that century, the Byzantine emperor Ἀλέξιος Κομνηνός Alexios I Komnenos ( r. 1081–1118) was approached by Anglo-Saxon refugees, who had left England following the Norman Conquest. Alexios offered land to these refugees in ''Thema Khersonos'' if they cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Sea Fleet
The Black Sea Fleet () is the Naval fleet, fleet of the Russian Navy in the Black Sea, the Sea of Azov and the Mediterranean Sea. The Black Sea Fleet, along with other Russian ground and air forces on the Crimea, Crimean Peninsula, are subordinate to the Southern Military District of the Russian Armed Forces. The fleet traces its history to its founding by Grigory Potemkin, Prince Potemkin on 13 May 1783 as part of the Imperial Russian Navy. The Russian Soviet Federative Socialist Republic, Russian SFSR inherited the fleet in 1918; with the founding of the Soviet Union in 1922, it became part of the Soviet Navy. Following the Dissolution of the Soviet Union, collapse of the Soviet Union in 1991, the Black Sea Fleet was partitioned between the Russia, Russian Federation and Ukraine in 1997, with Russia receiving title to 82% of the vessels. The Black Sea Fleet has its official primary headquarters and facilities at the Sevastopol Naval Base, Crimea, which Annexation of Crimea by ...

Multiple Rocket Launcher
A multiple rocket launcher (MRL) or multiple launch rocket system (MLRS) is a type of rocket artillery system that contains multiple rocket launcher, launchers which are fixed to a single weapons platform, platform, and shoots its rocket (weapon), rocket ordnance in a fashion similar to a volley gun. Rockets are self-propelled in flight and have different capabilities than conventional artillery shell (projectile), shells, such as longer effective range, lower recoil, typically considerably higher payload than a similarly sized gun artillery platform, or even carrying multiple warheads. Unguided rocket artillery is notoriously inaccurate and slow to reload compared to gun artillery. A multiple rocket launcher helps compensate for this with its ability to launch multiple rockets in rapid succession, which, coupled with the large blast radius, kill zone of each warhead, can easily deliver saturation fire over a target area. However, modern rockets can use GPS or inertial guidance t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Satellite Imagery
Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world. Satellite imaging companies sell images by licensing them to governments and businesses such as Apple Maps and Google Maps. History The first images from space were taken on Sub-orbital spaceflight, sub-orbital flights. The US-launched V-2 flight on October 24, 1946, took one image every 1.5 seconds. With an Apsis, apogee of 65 miles (105 km), these photos were from five times higher than the previous record, the 13.7 miles (22 km) by the Explorer II balloon mission in 1935. The first satellite (orbital) photographs of Earth were made on August 14, 1959, by the U.S. Explorer 6. The first satellite photographs of the Moon might have been made on October 6, 1959, by the Soviet satellite Luna 3, on a mission to photograph the far side of the Moon. The Blue Marble ...

Black Sea
The Black Sea is a marginal sea, marginal Mediterranean sea (oceanography), mediterranean sea lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia (country), Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is Inflow (hydrology), supplied by major rivers, principally the Danube, Dnieper and Dniester. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea, not including the Sea of Azov, covers , has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end ...

Sympathetic Detonation
A sympathetic detonation (SD, or SYDET), also called flash over or secondary/secondaries (explosion), is a detonation, usually unintended, of an explosive charge by a nearby explosion. Definition A sympathetic detonation is caused by a shock wave, or impact of primary or secondary blast fragments. The initiating explosive is called the donor explosive, the initiated one is known as the receptor explosive. In case of a chain detonation, a receptor explosive can become a donor one. The shock sensitivity, also called gap sensitivity, which influences the susceptibility to sympathetic detonations, can be measured by gap tests. If detonators with primary explosives are used, the shock wave of the initiating blast may set off the detonator and the attached charge. However even relatively insensitive explosives can be set off if their shock sensitivity is sufficient. Depending on the location, the shock wave can be transported by air, ground, or water. The process is probabilist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feodosia
Feodosia (, ''Feodosiia, Teodosiia''; , ''Feodosiya''), also called in English Theodosia (from ), is a city on the Crimean coast of the Black Sea. Feodosia serves as the administrative center of Feodosia Municipality, one of the regions into which Crimea is divided. During much of its history, the city was a significant settlement known as Caffa () or Kaffa ( Old Crimean Tatar/Ottoman Turkish: ; Crimean Tatar/). According to the 2014 census, its population was 69,145. History Theodosia (Greek colony) The city was founded as ''Theodosia'' (Θεοδοσία) by Greek colonists from Miletos in the 6th century BC. Noted for its rich agricultural lands, on which its trade depended, the city was destroyed by the Huns in the 4th century AD. Theodosia remained a minor village for much of the next nine hundred years. It was at times part of the sphere of influence of the Khazars (excavations have revealed Khazar artifacts dating back to the 9th century) and of the Byzantine Empi ...

Cruise Missile
A cruise missile is an unmanned self-propelled guided missile that sustains flight through aerodynamic lift for most of its flight path. Cruise missiles are designed to deliver a large payload over long distances with high precision. Modern cruise missiles are capable of traveling at high Aerodynamics#Incompressible aerodynamics, subsonic, Supersonic speed, supersonic, or Hypersonic speed, hypersonic speeds, are self-navigating, and are able to fly on a non-Ballistics, ballistic, extremely low-altitude trajectory. History The idea of an "aerial torpedo" was shown in the British 1909 film ''The Airship Destroyer'' in which flying torpedoes controlled wirelessly are used to bring down airships bombing London. In 1916, the Americans, American Aircraft pilot, aviator Lawrence Sperry built and patented an "aerial torpedo", the Hewitt-Sperry Automatic Airplane, a small biplane carrying a TNT charge, a Sperry autopilot and barometric altitude control. Inspired by the experiments, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
