Yuan Wang-class Tracking Ship
The Yuan Wang-class of tracking ships () are used for tracking and support of satellite and intercontinental ballistic missiles by the People's Liberation Army Strategic Support Force of the People's Republic of China (PRC). It is important to note that the class is not a single class of identical design, but instead, a group of different designs grouped under the same series that share the same name. Detailed specifications for every ship have not been released by the PLASSF. ''Yuan Wang 1'' and ''Yuan Wang 2'' are thought to have a displacement tonnage of around 21,000 tons when fully loaded, with a crew of about 470 and a length of about . Their propulsion is from one Sulzer Ltd. diesel engine, with a top speed of 20 knots (37 km/h). The class was first proposed by Premier Zhou Enlai in 1965, and the idea was personally approved by Mao Zedong in 1968. The first two ships of the class, ''Yuan Wang 1'' and ''Yuan Wang 2'', were built at the Jiangnan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tracking Ship
A tracking ship, also called a missile range instrumentation ship or range ship, is a ship equipped with antennas and electronics to support the launching and tracking of missiles and rockets. Since many missile ranges launch over ocean areas for safety reasons, range ships are used to extend the range of shore-based tracking facilities. In the United States, the initial tracking ships were constructed by the U.S. Army and then the U.S. Air Force to support their missile programs. They were generally built on a surplus Liberty ship or Victory ship hull. By 1964, the U.S. Navy took over all the range ships and introduced more. In some Navies, such a ship is also given the Type Designation "Vigilship" or "Veladora", with the Designation Letter "V" or Letters "VC". Missile range instrumentation ships Chinese PLA Strategic Support Force The Chinese ships were purpose built vessels for their role in the navy and the space program. * Yuanwang class ** ''Yuanwang 1'', 1977 – pres ...

Long March 5
Long March 5 (LM-5; zh, s=长征五号 , p=Chángzhēng wǔ hào), or Changzheng 5 (CZ-5), and also by its nickname "''Pang-Wu''" (胖五, "''Fat-Five''"), is a Chinese heavy-lift launch vehicle developed by the China Academy of Launch Vehicle Technology (CALT). It is the first Chinese launch vehicle designed to use exclusively non-hypergolic liquid propellants. It is the fifth iteration of the Long March rocket family. There are currently two CZ-5 variants: CZ-5 and CZ-5B. The maximum payload capacities are approximately to low Earth orbit (for CZ-5B) and approximately to geostationary transfer orbit (for CZ-5). As of 2021, a 3-core human-rated variant, referred to as CZ-5G, designed for manned moon mission, is under development; this variant will be capable of launching a crewed spacecraft into lunar orbit. The Long March 5 roughly matches the capabilities of American NSSL heavy-lift launch vehicles such as the Delta IV Heavy. It is currently the most powerful member of ...
