Lianyungang
Lianyungang () is a prefecture-level city in northeastern Jiangsu province of China, province, China. It borders Yancheng to its southeast, Huai'an and Suqian to its south, Xuzhou to its southwest, and the province of Shandong to its north. Its name derives from Lian Island, the largest island in Jiangsu which lies off its coastline, and Yuntai Mountain, the highest peak in Jiangsu, a few miles from the city center, and the fact that it is a port. The name can be literally translated as the Port Connecting the Clouds. Lianyungang was home to 4.65 million inhabitants as of the 2020 census whom 1,210,767 lived in the built-up (''or metro'') area made of Haizhou and Lianyun counties.

Link 11
TADIL-A/Link 11 is a secure half-duplex tactical data link used by NATO to exchange digital data. It was originally developed by a joint committee including members from the Royal Canadian Navy, US Navy and Royal Navy to pass accurate targeting information between ships. The final standard was signed in Ottawa in November 1957, where the British proposed the name "TIDE" for "Tactical International Data Exchange". It was later made part of the NATO STANAG standardization process. The system operates on two frequencies, one in the high frequency (HF) range for over-the-horizon (OTH) communications, and another in the ultra high frequency (UHF) range that uses much smaller antennas and is suitable for smaller ships but lacks the OTH performance. The system broadcasts packets of 30 bits length, with 6 bits of error correction and 24 bits of payload data. The payload is encrypted. Link 14 was adopted at the same time as a low-end counterpart to Link 11. Link 14 is essentially a digi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performing of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back millennia, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and in addition to the size and weight of the vessel represents a considerable engineering challenge as well as a public spectacle. The process also involves Sailors' superstitions, many traditions intended to invite good luck, such as baptism#Boats and ships, christening by breaking a sacrificial bottle of champagne over the bow (ship), bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The ol ...

East Sea Fleet
The Eastern Theater Command Navy (东部战区海军, ETCN) is a formation of China's People's Liberation Army Navy (PLAN) and the naval component of the Eastern Theater Command. The ETCN was reorganized from the East Sea Fleet (ESF) by 2016. Currently Wang Zhongcai is the commander of the ESF and Mei Wen it's political commissar. History The PLAN was formed toward the end of the Chinese Civil War. In March 1949, Zhang Aiping of the Third Field Army was ordered by the Central Military Commission (CMC) of the Chinese Communist Party to create a naval force from the field army. Zhang's only previous naval experience was organizing an irregular riverine force near Hongze Lake in 1941 and leading it in a successful campaign against local bandits. The PLAN was created on 21 April when Zhang established the East China Military Region Navy, or East China Navy (ECN), with a thirteen-member headquarters, and he was formally appointed by the CMC as the ECN's commander and commissar ...

"successors") — Abu Bakr, Umar, Uthman, and Ali collectively — believed to Political aspects of Islam, represent the perfect Islam and governance who led the Muslim community and polity from the death of the Islamic prophet Muhammad (in 632 AD), to the establishment of the Umayyad Caliphate (in 661 AD). The reign of these four caliphs is considered in Sunni Islam to have been "rightly-guided", meaning that it sunnah, constitutes a model to be followed and emulated from a religious point of view. This term is not used by Shia Muslims, who reject the rule of the first three caliphs as illegitimate. Following Muhammad's death in June 632, Muslim leaders debated who Succession to Muhammad, should succeed him.

Hangar
A hangar is a building or structure designed to hold aircraft or spacecraft. Hangars are built of metal, wood, or concrete. The word ''hangar'' comes from Middle French ''hanghart'' ("enclosure near a house"), of Germanic origin, from Frankish *''haimgard'' ("home-enclosure", "fence around a group of houses"), from *''haim'' ("home, village, hamlet") and ''gard'' ("yard"). The term, ''gard'', comes from the Old Norse ''garðr'' ("enclosure, garden"). Hangars are used for protection from the weather, direct sunlight and for maintenance, repair, manufacture, assembly and storage of aircraft. History The Wright brothers stored and repaired their aircraft in a wooden hangar constructed in 1902 at Kill Devil Hills in North Carolina for their Glider aircraft, glider. After completing design and construction of the ''Wright Flyer'' in Ohio, the brothers returned to Kill Devil Hills only to find their hangar damaged. They repaired the structure and constructed a new workshop while t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, duri ...

Type 79 100 Mm Naval Gun
The Type 79 Twin 100 mm gun is the first indigenously developed large caliber Chinese naval gun. A decision was made in 1970 to replace the Soviet 100/56 B-34 single 100 mm semi-enclosed gun mount. By June 1973, the first batch was completed and two were installed onboard frigates for test and evaluation. Two more upgrades were eventually developed. Type 79 The first of the family, this gun was fully automatic and controlled by Type 343 radar. However, being the first fully automatic gun and the first indigenously developed gun at the same time, the Chinese was not confident enough on the design, and thus incorporated manual backup systems. This proved to be baseless because later operation proved that the reliability of the automated system was just as good as the simpler manual system. Type 79A (H/PJ33A) Based on the successful performance of the automated system, the manual backup system was eliminated in this upgrade. As a result, the total weight and size ...

Anti-ship Missile
An anti-ship missile (AShM or ASM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea-skimming variety, and many use a combination of inertial guidance and active radar homing. A large number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. Many anti-ship missiles can be launched from a variety of weapons systems including surface warships (also referred to as ship-to-ship missiles), submarines, bombers, fighter planes, patrol planes, helicopters, shore batteries, land vehicles, and, conceivably, even infantrymen firing shoulder-launched missiles. The term surface-to-surface missile (SSM) is used when appropriate. The longer-range anti-ship missiles are often called anti-ship cruise missiles. Several countries are also developing anti-ship ballistic missiles. Etymology Both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
