Lianyungang
Lianyungang () is a prefecture-level city in northeastern Jiangsu 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 4,599,360 inhabitants as of the 2020 census whom 1,210,767 lived in the built-up (''or metro'') area made of Haizhou and Lianyun counties. Lianyungang was known in the West as Haichow (Postal romanization), which means the City of Sea. Haichow was opened to foreign trade by the Qing imperial government in 1905. Geography Lianyungang is between 118°24' and 119°48' east longitude and 34°11' and 35°07' north latitude. Lianyungang covers an area of . ...

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 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 digital t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, 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 many traditions intended to invite good luck, such as 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 oldest, most familiar, and most widel ...

East Sea Fleet
The Eastern Theater Command Navy (), or East Sea Fleet (ESF; ), is one of the three fleets of the People's Liberation Army Navy, operating in the East China Sea under the Eastern Theater Command. It was the first naval force formed by the People's Liberation Army, on 23 April 1949 and was initially based at Shanghai. Renamed in 1955, it has since been assigned to be part of the People's Liberation Army Navy and its headquarters have been moved to Ningbo, Zhejiang Province, but the fleet continues to patrol the East China Sea. Its flagship is the Type 052C destroyer ''Changchun''. The fleet was used in a support role during the People's Liberation Army's (PLA) invasion of the Kuomintang-held island of Yijiangshan on 14 January 1955. It has engaged in numerous other battles against the Republic of China Armed Forces. It has also operated in support of the South Sea Fleet against the People's Army of Vietnam during the 1980s.

People's Liberation Army Navy
The People's Liberation Army Navy (PLAN; ), also known as the People's Navy, Chinese Navy, or PLA Navy, is the maritime service branch of the People's Liberation Army. The PLAN traces its lineage to naval units fighting during the Chinese Civil War and was established on 23 April 1949. Throughout the 1950s and early 1960s, the Soviet Union provided assistance to the PLAN in the form of naval advisers and export of equipment and technology. Until the late 1980s, the PLAN was largely a riverine and littoral force (brown-water navy). In the 1990s, following the fall of the Soviet Union and a shift towards a more forward-oriented foreign and security policy, the leaders of the Chinese military were freed from worrying overland border disputes. Traditionally subordinated to the PLA Ground Force, PLAN leaders were now able to advocate for a renewed attention towards the seas. Chinese military officials have outlined plans to operate in the first and second island chains, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rashidun Caliphate
The Rashidun Caliphate ( ar, اَلْخِلَافَةُ ٱلرَّاشِدَةُ, al-Khilāfah ar-Rāšidah) was the first caliphate to succeed the Islamic prophet Muhammad. It was ruled by the first four successive caliphs of Muhammad after his death in 632 CE (11 AH). During its existence, the empire was the most powerful economic, cultural, and military force in West Asia. The caliphate arose following Muhammad’s passing in June 632 and the subsequent debate over the succession to his leadership. Muhammad's childhood friend and close companion Abu Bakr (), of the Banu Taym clan, was elected the first caliph in Medina and he began the conquest of the Arabian Peninsula. His brief reign ended in August 634 when he died and was succeeded by Umar (), his appointed successor from the Banu Adi clan. Under Umar, the caliphate expanded at an unprecedented rate, ruling more than two-thirds of the Byzantine Empire and nearly the entire Sasanian Empire. Umar was assassinated in ...

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. 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 they waited f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive hydraulic shock. Most depth charges use high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, 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, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a " nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a surface ship, or a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Type 79 100 Mm Naval Gun
{{unreferenced, date=April 2009 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 Bu-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 Based on the successful performance of the automated system, the manual backup system was eliminated in this upgrade. As a result, the ...

Anti-ship Missile
An anti-ship missile (AShM) 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 good 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. The first anti-ship missiles, which were developed and built by Nazi Germany, used radio command guidance.https://airandspace.si.edu/collection-objects/bomb-guided-fritz-x-x-1/nasm_A19840794000#:~:text=The%20Fritz%20X%2C%20also%20known,the%20Henschel%20Hs%20293%20missile. These saw some success in the Mediterranean Theatre during 1943–44, sinking or heavily damaging at least 31 ships with the Henschel Hs 293 and more than seven with the '' Fritz X'', including the Italian battleship ''Roma'' and the light cruiser .
