Cartagena, Spain
Cartagena () is a Spanish city and a major naval station on the Mediterranean coast, south-eastern Iberia. As of January 2018, it has a population of 218,943 inhabitants, being the region's second-largest municipality and the country's sixth-largest non-provincial-capital city. The metropolitan area of Cartagena, known as '' Campo de Cartagena'', has a population of 409,586 inhabitants. Cartagena has been inhabited for over two millennia, being founded around 227 BC by the Carthaginian Hasdrubal the Fair as ''Qart Hadasht'' ( phn, 𐤒𐤓𐤕𐤟𐤇𐤃𐤔𐤕 QRT𐤟ḤDŠT; meaning "New Town"), the same name as the original city of Carthage. The city had its heyday during the Roman Empire, when it was known as ''Carthago Nova'' (the New Carthage) and ''Carthago Spartaria'', capital of the province of Carthaginensis. Much of the historical significance of Cartagena stemmed from its coveted defensive port, one of the most important in the western Mediterranean. Cartagena has ...

Severnaya Verf
Severnaya Verf (russian: Северная верфь, , Northern Shipyard) is a major shipyard on in Saint Petersburg, Russia, producing naval and civilian ships. It was founded as a branch of the Putilov Plant in the late 1800s. Under the Soviets, the shipyard was generally known as Shipyard No. 190 (in the name of Zhdanov) and reverted to its former name in 1989. The priority market for ''Severnaya Verf'' is military export to Asian countries as India, China and Vietnam. History The shipyard was established by 1912 with the name of Putilov Shipyard (Russian: ''Putilovskaya Verf''). It was situated near the main Putilov factory, and began building small warships, up to destroyers in size, in addition to non-military ships for the government like dredgers, tugboats, etc. Under Bolshevik control it was known as the ''Severnaya Verf'' and was then renamed ''Severnaya sudostroitel'naya verf'' in the early Twenties. It was given the honorific "in the name of Zhdanov" in 1935 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Missile Defense
Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and also the destruction of attacking missiles. Conceived as a defense against nuclear-armed intercontinental ballistic missiles (ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles. China, France, India, Iran, Israel, Italy, Russia, Taiwan, the United Kingdom and the United States have all developed such air defense systems. Missile defense categories Missile defense can be divided into categories based on various characteristics: type/range of missile intercepted, the trajectory phase where the intercept occurs, and whether intercepted inside or outside the Earth's atmosphere: Type/range of missile intercepted These types/ranges include strategic, theater and tactical. Each entails unique requirements for intercept, and a defensive system capable of intercepting one missile type frequently cannot intercept others. H ...

Chaff (countermeasure)
Chaff, originally called Window by the British and ''Düppel'' by the Second World War era German Luftwaffe (from the Berlin suburb where it was first developed), is a radar countermeasure in which aircraft or other targets spread a cloud of small, thin pieces of aluminium, metallized glass fibre or plastic, which either appears as a cluster of primary targets on radar screens or swamps the screen with multiple returns, in order to confuse and distract. Modern armed forces use chaff (in naval applications, for instance, using short-range SRBOC rockets) to distract radar-guided missiles from their targets. Most military aircraft and warships have chaff dispensing systems for self-defense. An intercontinental ballistic missile may release in its midcourse phase several independent warheads as well as penetration aids such as decoy balloons and chaff. Modern radar systems can distinguish chaff from target objects by measuring the Doppler shift; chaff quickly loses speed compared ...

Fire-control System
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director, and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately. Naval based fire control Origins The original fire-control systems were developed for ships. The early history of naval fire control was dominated by the engagement of targets within visual range (also referred to as direct fire). In fact, most naval engagements before 1800 were conducted at ranges of . Even during the American Civil War, the famous engagement between and was often conducted at less than range. Rapid technical improvements in the late 19th century greatly increased the range at which gunfire was possible. Rifled guns of much larger size firing explosive shells of lighter relative weight (compared to all-metal balls) so greatly increa ...

Navigation Radar
Radar navigation is the utilization of marine and aviation radar systems for vessel and aircraft navigation. When a craft is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted objects and use these to establish arcs of position and lines of position on a chart.Maloney, 2003:744. A fix consisting of only radar information is called a ''radar fix''.Bowditch, 2002:816. Some types of radar fixes include the relatively self-explanatory methods of "range and bearing to a single object,"National Imagery and Mapping Agency, 2001:163. "two or more bearings," "tangent bearings," and "two or more ranges." Parallel indexing is a technique defined by William Burger in the 1957 book ''The Radar Observer's Handbook''.National Imagery and Mapping Agency, 2001:169. This technique involves creating a line on the screen that is parallel to the ship's course, but offset to the left or right by some distance. This p ...

Search Radar
This is a list of different types of radar. Detection and search radars Search radars scan great volumes of space with pulses of short radio waves. They typically scan the volume two to four times a minute. The waves are usually less than a meter long. Ships and planes are metal, and reflect radio waves. The radar measures the distance to the reflector by measuring the time of the roundtrip from emission of a pulse to reception, dividing this by two, and then multiplying by the speed of light. To be accepted, the received pulse has to lie within a period of time called the ''range gate''. The radar determines the direction because the short radio waves behave like a search light when emitted from the reflector of the radar set's antenna.

9K33 Osa
The 9K33 ''Osa'' (, literally "wasp"; NATO reporting name SA-8 ''Gecko'') is a highly mobile, low-altitude, short-range tactical surface-to-air missile system developed in the Soviet Union in the 1960s and fielded in 1972. Its export version name is Romb. Development Design work on an entirely new, self-propelled air defense guided missile system began in 1960 and was assigned to the Moscow-based () research and design institute under lead designer M.M. Kosichkin. The program initially suffered numerous delays and setbacks due to poorly formulated performance and tactical requirements, as this was a pioneering battlefield air defense system with no equivalents in existence at the time, and no doctrinal experience with such a weapon. P.M. Chukadov was assigned project leader in 1965 after a thorough review of the stalled program. The Osa had service acceptance in 1972 after a period of trials. Description The Osa was the first mobile air defense missile system incorporating it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...
