NMS Delfinul
NMS ''Delfinul'' (''The Dolphin'') was a Romanian submarine that served in the Black Sea during the Second World War. It was the first submarine of the Romanian Navy, built in Italy under Romanian supervision. Construction and specifications ''Delfinul'' was ordered in 1927 from the Italian naval base and shipyard at Fiume (today Rijeka, Croatia). It was completed in 1931, but was accepted by Romania as the country's first submarine only in 1936, after the many corrections required by the Romanians were completed. She had a Displacement (ship), surfaced displacement of 650 tons, which grew to 900 tons when submerged. The boat measured in length, with a Beam (nautical), beam of and a Draft (hull), draught of . Her power plant consisted of two Sulzer diesel engines and two electric motors powering two Propeller, shafts, giving her a top speed of on the surface and submerged. Her Ship's company, crew amounted to 55. She was armed with eight torpedo tubes (4 bow and 4 stern), one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingdom Of Romania
The Kingdom of Romania ( ro, Regatul României) was a constitutional monarchy that existed in Romania from 13 March ( O.S.) / 25 March 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I (thus beginning the Romanian royal family), until 1947 with the abdication of King Michael I of Romania and the Romanian parliament's proclamation of the Romanian People's Republic. From 1859 to 1877, Romania evolved from a personal union of two vassal principalities (Moldavia and Wallachia) under a single prince to an autonomous principality with a Hohenzollern monarchy. The country gained its independence from the Ottoman Empire during the 1877–1878 Russo-Turkish War (known locally as the Romanian War of Independence), when it also received Northern Dobruja in exchange for the southern part of Bessarabia. The kingdom's territory during the reign of King Carol I, between 13 ( O.S.) / 25 March 1881 and 27 September ( O.S.) / 10 October 1914 is sometimes refe ...

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the sea at the ambien ...

Novorossiysk
Novorossiysk ( rus, Новоросси́йск, p=nəvərɐˈsʲijsk; ady, ЦIэмэз, translit=Chəməz, p=t͡sʼɜmɜz) 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 honored with the title of the Hero City. Population: History In antiquity, the shores of the Tsemes Bay were the site of Bata ( el, Μπάτα), 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 Engl ...

Reconnaissance
In military operations, reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, terrain, and other activities. Examples of reconnaissance include patrolling by troops ( skirmishers, long-range reconnaissance patrol, U.S. Army Rangers, cavalry scouts, or military intelligence specialists), ships or submarines, crewed or uncrewed reconnaissance aircraft, satellites, or by setting up observation posts. Espionage is usually considered to be different from reconnaissance, as it is performed by non-uniformed personnel operating behind enemy lines. Often called recce (British, Canadian and Australian English) or recon (American English), the word for this activity has at its root the associated verb ''reconnoitre'' or ''reconnoiter''. Etymology The word from the Middle French ''reconoissance''. Overview Reconnaissance conducted by ground forces includes special reconnaissance, armored reconnaissance, amph ...

Crimean Peninsula
Crimea, crh, Къырым, Qırım, grc, Κιμμερία / Ταυρική, translit=Kimmería / Taurikḗ ( ) is a peninsula in Ukraine, on the northern coast of the Black Sea, that has been occupied by Russia since 2014. It has a population of 2.4 million. The peninsula is almost entirely surrounded by the Black Sea and the smaller Sea of Azov. The Isthmus of Perekop connects the peninsula to Kherson Oblast in mainland Ukraine. To the east, the Crimean Bridge, constructed in 2018, spans the Strait of Kerch, linking the peninsula with Krasnodar Krai in Russia. The Arabat Spit, located to the northeast, is a narrow strip of land that separates the Sivash lagoons from the Sea of Azov. Across the Black Sea to the west lies Romania and to the south is Turkey. Crimea (called the Tauric Peninsula until the early modern period) has historically been at the boundary between the classical world and the steppe. Greeks colonized its southern fringe and were absorbed by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raid On Constanța
The Raid on Constanța was an attack by the Soviet Black Sea Fleet on the Romanian port of Constanța on 26 June 1941, shortly after the beginning of Operation Barbarossa, the Axis invasion of the Soviet Union, and resulted in the only encounter between major warships in the Black Sea during World War II. The attack was intended to be a coordinated effort between the fleet's ships and aircraft to split the attention of the defenders, but the bombers did not attack at the designated times. Two destroyer leaders were ordered to bombard the port in the early morning, covered by a cruiser and a destroyer. They caused some damage, but they were engaged by Axis coastal artillery and several Romanian ships. The two destroyer leaders were slightly damaged and withdrew under fire, steaming into a Romanian minefield; one of the destroyer leaders was sunk and the cruiser was damaged by the mines as they departed the area. Several groups of bombers later bombed the city that day and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought battleship. With the advent of the dreadnought battleship before Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constantin Costăchescu
Constantin "Bibi" Costăchescu (12 April 1909–8 August 1983) was a submarine commander in the Romanian Navy during the Second World War. He is the only Romanian submarine commander to sink an enemy ship. Early days He was born in 1909 in Pleșești, Suceava County, the son of Olga and Vasile Costăchescu, both teachers. He went to school in his native village and in Fălticeni, after which he attended military school in Iași, graduating in 1928. He then enrolled in the Naval Academy in Constanța, finishing in 1930 second in his class, with the rank of aspirant. Costăchescu served on the destroyer NMS Mărășești and in 1933 graduated from the Special Naval School. The attack On 1 October 1938, Costăchescu was appointed second in command of NMS Dolphin, and from 1 October 1939 to November 1943, he served as its commanding officer (CO). In June 1941 Romania entered World War II on the side of the Axis powers; in October of that year, the Romanian Army joined in the Crime ...

Fleet In Being
In naval warfare, a "fleet in being" is a naval force that extends a controlling influence without ever leaving port. Were the fleet to leave port and face the enemy, it might lose in battle and no longer influence the enemy's actions, but while it remains safely in port, the enemy is forced to continually deploy forces to guard against it. A "fleet in being" can be part of a sea denial doctrine, but not one of sea control. Use of the term The term was first used in 1690 when Lord Torrington, commander of the Royal Navy forces in the English Channel, found himself facing a stronger French fleet. He proposed avoiding a sea battle, except under very favourable conditions, until he could be reinforced. By thus keeping his "fleet in being", he could maintain an active threat which would force the enemy to remain in the area and prevent them from taking the initiative elsewhere. Secondary use Rudyard Kipling published a series of articles about the British Channel Fleet under the ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convoy
A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support and can help maintain cohesion within a unit. It may also be used in a non-military sense, for example when driving through remote areas. Naval convoys Age of Sail Naval convoys have been in use for centuries, with examples of merchant ships traveling under naval protection dating to the 12th century. The use of organized naval convoys dates from when ships began to be separated into specialist classes and national navies were established. By the French Revolutionary Wars of the late 18th century, effective naval convoy tactics had been developed to ward off pirates and privateers. Some convoys contained several hundred merchant ships. The most enduring system of convoys were the Spanish treasure fleets, that sailed from the 1520s until 1790. When merchant ships sailed independently, a privateer ...

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
