Chinese Submarine Changzheng 1
''Changzheng 1'' (401) ("Long March 1") is a decommissioned Type 091 nuclear attack submarine of the People's Liberation Army Navy. Development and design The 091 nuclear submarine is the first nuclear submarine developed by the People's Republic of China. It has been completed and put into service since 1970. A total of 5 ships have been built and deployed in the North Sea Fleet of the Chinese People's Liberation Army. There are still three ships of this type currently in service. China's nuclear submarine program started in June 1958. Because the Soviet Union did not provide support, it was struggling without external help, and was forced to temporarily shelve it from 1963. Thus, starting in 1965, China began to build onshore simulated reactors as a power test for future nuclear submarines. The PLA Navy has developed a plan to develop two nuclear-powered submarines, including a nuclear-powered attack nuclear submarine, and a ballistic missile nuclear submarine modified o ...

Qingdao
Qingdao, Mandarin: , (Qingdao Mandarin: t͡ɕʰiŋ˧˩ tɒ˥) is a prefecture-level city in the eastern Shandong Province of China. Located on China's Yellow Sea coast, Qingdao was long an important fortress. In 1897, the city was ceded to Germany. For the Germans Qingdao (Tsingtau) was a strategic trade center, port and base for its East Asia Squadron, allowing the German navy to project dominance in the Pacific. In 1914, following the outbreak of World War I, Japan occupied the city and the surrounding province during the Siege of Tsingtao. In 1915, China agreed to recognize Japan's special position in the territory through what became known as the Twenty-One Demands. In 1918, the Chinese government, under the control of the warlord Duan Qirui, secretly agreed to Japanese terms in exchange for a loan. Following the First World War, during the Paris Peace Conference, Japan secured agreements with the Allied powers to recognize its claim to the areas in Shandong, which in ...

Ships Built In China
A ship is a large vessel that travels the world's oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), oil tankers (28%) and container ships (14%). Nomenclature Ships are typically larger than boats, but there is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1970 Ships
Year 197 ( CXCVII) was a common year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Museum Ship
A museum ship, also called a memorial ship, is a ship that has been preserved and converted into a museum open to the public for educational or memorial purposes. Some are also used for training and recruitment purposes, mostly for the small number of museum ships that are still operational and thus capable of regular movement. Several hundred museum ships are kept around the world, with around 175 of them organised in the Historic Naval Ships AssociationAbout The Historic Naval Ships Association (the international Historic Naval Ships Association website. Accessed 2008-06-06.) though many are not naval museum ships, from general merchant ships to tugboat, tugs and Lightvessel, lightships. Many, if not most, museum ships are also associated with a maritime museum. Significance Relatively few ships are ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Sea Fleet
The North Sea Fleet (NSF; ), concurrently the Northern Theater Command Navy (), is one of the three fleets of China's People's Liberation Army Navy. Headquartered in Qingdao, Shandong, the fleet provides naval forces to the Northern Theater Command. In September 1950, the Qingdao Army Base was redesignated as a naval base. Following the departure of the Soviet Navy from Lüshunkou (Port Arthur), the North Sea Fleet was established in 1960 with naval bases in Qingdao and Lüshunkou. The fleet currently includes China's first aircraft carrier, ''Chinese aircraft carrier Liaoning, Liaoning'', as well as nuclear-powered attack and missile submarines. The North Sea Fleet was historically the most capable of the Navy's three fleets, being the first in China to operate destroyers, shore-based missiles and nuclear submarines. In recent years however, the shift in strengthening of importance and strategic capabilities of the East Sea Fleet, East and South Sea Fleet, South Sea Fleets are ...

Commissioned (ship)
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before it is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and Electronics, electronic systems, Galley (kitchen), galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify a ... [...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 ...

YJ-82
The YJ-82 () is a Chinese subsonic anti-ship cruise missile. It is manufactured by the China Aerospace Science and Industry Corporation Third Academy.Gromley et al.: page 101 The YJ-82 is the submarine-launched version of the YJ-8 missile family. Description The YJ-82 is a solid-fuelled rocket. It is launched from submarines from a buoyant launch canister. The YJ-82 lacks the solid-rocket booster of the surface-launched YJ-8/8A and likely has less range than the latter's 42 km. The terminal sea-skimming attack altitude is 5 to 7 meters. The launch capsule is a copy of the one used by submarine-launched Harpoons; China likely received the technology from Pakistan, which had such weapons. Development In the fall of 1983, the People's Liberation Army Navy (PLAN) test fired YJ-8 missiles from a modified Type 033 submarine; the submarine had to surface to fire, and six missiles could be fired in six to seven minutes. The missile's short range and surface launch left the submar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yu-3 Torpedo
The Yu-3 (鱼-3) is a Chinese acoustic homing torpedo designed to be fired from submarines against surface targets. It entered service with the Chinese Navy in 1984. Several sources state that it may be a copy of the Soviet SET-65E, although this seems unlikely as development began in 1965 after the Sino-Soviet split The Sino-Soviet split was the gradual worsening of relations between the People's Republic of China (PRC) and the Union of Soviet Socialist Republics (USSR) during the Cold War. This was primarily caused by divergences that arose from their .... It is therefore probably the first indigenously developed torpedo in China.

Yu-6 Torpedo
Yu-6 (鱼-6) torpedo is the Chinese counterpart of the US Mark 48 torpedo, and it is the first domestic Chinese torpedo designed to counter both surface ships and submarines from the very start. Guidance can be by wire, active and passive homing, or wake homing. Domestic Chinese sources have claimed that the Yu-6 torpedo is in the same class as the Mk 48 Mod. 4 torpedo, and it is believed to have been cloned from a captured sample, but official information on the Yu-6 torpedo is limited. Developmental history Mk 48 capture and early development At least one Mark 48 torpedo was reportedly recovered by Chinese fishermen in the late 1970s or early 1980s, and the government of China might have begun reverse engineering in the 1980s. However, due to the inexperience of the Chinese technological base at the time and the concentration on economic development, most of the reverse engineering project was put on hold after research had been completed on Otto fuel II, wire guidance a ...
