Osprey Class Submersible
Osprey class submersible is a class of submersible of the People's Liberation Army Navy (PLAN) specially designed to perform torpedo retrieving missions at test ranges. This class submersible was highly classified when it originally entered service in 1989, and it was not until more than a decade later in the mid of the first decade of the 21st century when it was revealed to the public, when one of the design team members, the deputy general designer Mr. Sun Xin (孙欣), was publicized in a 2006 interview to disclose some characteristics of the submersible. This class is currently consisted of two boats, Osprey 1 (鱼鹰1号, Yu Ying Yi Hao) and Osprey 2 (鱼鹰2号, Yu Ying Er Hao). Origin In 1969, the 705th Research Institute of China Shipbuilding Industry Corporation (CSIC) led a team consisting of more than eighty research establishments and factories had completed No. 750 Deep Water Test Range, which was the main test range for Chinese torpedoes, depth charges and naval ...

Submersible
A submersible is an underwater vehicle which needs to be transported and supported by a larger ship, watercraft or dock, platform. This distinguishes submersibles from submarines, which are self-supporting and capable of prolonged independent operation at sea. There are many types of submersibles, including both human-occupied vehicles (HOVs) and uncrewed craft, variously known as remotely operated vehicles (ROVs) or unmanned underwater vehicles (UUVs). Submersibles have many uses including oceanography, underwater archaeology, ocean exploration, tourism, underwater work, equipment maintenance and underwater search and recovery, recovery and underwater videography. History The first recorded self-propelled underwater vessel was a small oar-powered submarine conceived by William Bourne (mathematician), William Bourne (c. 1535 – 1582) and designed and built by Dutch inventor Cornelis Drebbel in 1620, with two more improved versions built in the following four years.Konstam (201 ...

Wuchang District
Wuchang is one of 13 urban districts of the prefecture-level city of Wuhan, the capital of Hubei Province, China. It is the oldest of the three cities that merged into modern-day Wuhan, and stood on the right (southeastern) bank of the Yangtze River, opposite the mouth of the Han River. The two other cities, Hanyang and Hankou, were on the left (northwestern) bank, separated from each other by the Han River. The name "Wuchang" remains in common use for the part of urban Wuhan south of the Yangtze River. Administratively, however, it is split between several districts of the City of Wuhan. The historic center of Wuchang lies within the modern Wuchang District, which has an area of and a population of 1,102,188. Other parts of what is colloquially known as Wuchang are within Hongshan District (south and south-east) and Qingshan District (north-east). Presently, on the right bank of the Yangtze, it borders the districts of Qingshan (for a very small section) to the north ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially, a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though somet ...

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 7103 DSRV
The People's Republic of China developed a class of 35-ton deep-submergence rescue vehicle (DSRV) for the People's Liberation Army Navy (PLAN). It was first tested in 1986 and operational in 1989. The DSRV may perform a rescue at depths up to . Six or 22 survivors could be carried. This suited contemporary PLAN submarines which deployed infrequently and typically to coastal waters. The submarine may also perform salvage work. It has a manipulator arm and a diving chamber A diving chamber is a vessel for human occupation, which may have an entrance that can be sealed to hold an internal pressure significantly higher than ambient pressure, a pressurised gas system to control the internal pressure, and a supply of ... for six divers.

Dajiang-class Tender
The Type 925 Dajiang with NATO reporting name Dajiang, or 大江 in Chinese, meaning Great River, is a type of naval auxiliary ship belonging to the People's Republic of China. Each ship is usually equipped with up to two Type 7103 DSRV class Deep Submergence Rescue Vehicles (DSRVs). The ship is designed to replace the first People's Liberation Army Navy (PLAN) submarine tender PLANS Mount Tai, and the lead ship of the Dajiang class is the Changxingdao. The Type 925 is a submarine tender that can also be used as a submarine rescue ship, and hence, it is designated as a submarine support ship (Qian-Ting Zhi-Yuan Jian, 潜艇支援舰) by Chinese. Each ship has a crew of 308 sailors and is equipped with an aft helicopter deck and hangars for 2 Z-8 Super Frelon helicopters. These large multi role naval auxiliary ships are the most fexilible type in the Chinese navy, capable of performing a variety of tasks, including serving as a submarine rescue ship (ARS), marine salvage rescue s ...

Yu-4 Torpedo
Yu-4 (鱼-4) torpedo is the Chinese development of the Russian SAET-50 ASuW passive acoustic homing torpedo, and it is the Russian SAET-50 torpedo incorporating active acoustic homing guidance. Yu-4 torpedo is often erroneously claimed by many sources as the Chinese version of the SAET-60 acoustic homing torpedo, but Soviets had not completed the development of SAET-60 and only fielded the weapon in 1961, by then the relationship between former-Soviet Union and China had already worsened and China had not received any technical assistance on SAET-60 torpedo. The background of the development of Yu-4 torpedo is identical to that of Yu-1 torpedo and Yu-2 torpedo. Background In August, 1958, the deputy chief-of-staff of PLA Zhang Aiping and the deputy commander-in-chief of PLAN Luo Shunchu (罗舜初) led a military delegation to visit former-Soviet Union signed a deal with Soviets to produce three types of Soviet torpedoes in China.
