Yu-1 Torpedo
The Yu-1 (鱼-1) torpedo was the first Chinese-built steam-powered torpedo; it was a development of the unguided straight-running Soviet ASuW Type 53 torpedo. It was type classified in September 1971. The Yu-1 was actually the second domestically produced torpedo to enter Chinese service; the first was the Yu-2 torpedo. During the 1980s a version was developed with passive acoustic homing designated the Yu-1A. Development In August 1958, the deputy chief-of-staff of People's Liberation Army (PLA) Zhang Aiping and the deputy commander-in-chief of People's Liberation Army Navy (PLAN) Luo Shunchu (罗舜初) led a military delegation to visit the Soviet Union and signed a deal with Soviets to produce three types of Soviet torpedoes in China. In comparison with other military programs each with dozens or even hundreds of Soviet advisors, however, Soviet Union did not put too much emphasis on the torpedo capability: the total number of Soviet advisors initially sent to China for all o ...

CAPTOR Mine
The Mark 60 CAPTOR (Encapsulated Torpedo) is the United States' only deep-water anti-submarine naval mine. It uses a Mark 46 torpedo contained in an aluminum shell that is anchored to the ocean floor. The mine can be placed by either aircraft, submarine or surface vessel. The torpedo, once placed, can last anywhere from weeks to months underwater. The original production contract of the CAPTOR mine was awarded to Goodyear Aerospace Goodyear Aerospace Corporation (GAC) was the aerospace and defense subsidiary of the Goodyear Tire and Rubber Company. The company was originally operated as a division within Goodyear as the Goodyear Zeppelin Corporation, part of a joint project ... in 1972, and entered service in 1979. It was hoped to reduce minefield costs and used in the creation of a barrier of the "Greenland-Iceland-United Kingdom gap to interrupt Soviet submarines in the event that deterrence failed." The mine uses Reliable Acoustic Path (RAP) sound propagation to passively i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qinghai
Qinghai (; alternately romanized as Tsinghai, Ch'inghai), also known as Kokonor, is a landlocked province in the northwest of the People's Republic of China. It is the fourth largest province of China by area and has the third smallest population. Its capital and largest city is Xining. Qinghai borders Gansu on the northeast, Xinjiang on the northwest, Sichuan on the southeast and the Tibet Autonomous Region on the southwest. Qinghai province was established in 1928 during the period of the Republic of China, and until 1949 was ruled by Chinese Muslim warlords known as the Ma clique.

Liu Huaqing
Liu Huaqing (; 1 October 1916 – 14 January 2011) was Chinese revolutionary and an admiral of the People's Liberation Army Navy, who served as the third Commander-in-Chief of the Navy from 1982 through 1988. He is considered to have greatly contributed to the modernization of the Chinese Navy, and is hailed as the "father of the modern Chinese Navy" and "father of Chinese aircraft carriers". Biography Taking over the role of Navy Commander-in-Chief from his predecessor Ye Fei (who retired due to health problems), Liu had outlined a three-step process by which China would have a navy of global reach by the second half of the 21st century. In step one, from 2000 to 2010, China would develop a naval force that could operate up to the first island chain. In step two, from 2010 to 2020, China's navy would become a regional force capable of projecting force to the second island chain. In step three, to be achieved by 2040, China would possess a blue-water navy centered around a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microelectronics
Microelectronics is a subfield of electronics. As the name suggests, microelectronics relates to the study and manufacture (or microfabrication) of very small electronic designs and components. Usually, but not always, this means micrometre-scale or smaller. These devices are typically made from semiconductor materials. Many components of normal electronic design are available in a microelectronic equivalent. These include transistors, capacitors, inductors, resistors, diodes and (naturally) insulators and conductors can all be found in microelectronic devices. Unique wiring techniques such as wire bonding are also often used in microelectronics because of the unusually small size of the components, leads and pads. This technique requires specialized equipment and is expensive. Digital integrated circuits (ICs) consist of billions of transistors, resistors, diodes, and capacitors. Analog circuits commonly contain resistors and capacitors as well. Inductors are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
