Luhu Class Destroyer
The Type 052 (NATO/ OSD Luhu-class destroyer is a class of destroyers developed in the People's Republic of China (PRC) for the People's Liberation Army Navy (PLAN). The Type 052 was an intermediate between the obsolescent Type 051Kirchberger (2015): page 186 and the modern Type 052B destroyers.Kirchberger (2015): page 195McDevitt (2017): page 57 They were the first PLAN destroyers powered by gas turbines, and the first PLAN ships with modern combat direction systems (CDS). They were also part of the first generation of PLAN warships armed with surface-to-air missiles in the form of the short-range Crotale (called HQ-7 in Chinese service.)Kirchberger (2015): page 231 The Type 052 used subsystems imported from the United States and the European Union. The embargo after the 1989 Tiananmen Square protests and massacre ended the supply of and support for those subsystems, limiting production to two ships and likely impacting their operating efficiency due to system integration iss ...

People's Republic Of China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

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, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luzhou Class Destroyer
The Type 051C destroyer (NATO reporting name: Luzhou class) is a long-range air-defence guided-missile destroyer built by China in its ongoing effort to create a true blue water navy. The ship uses the hull design of the older Type 051B (Luhai class), but is equipped with the advanced Russian S-300FM air defence missiles systems. Currently, two ships of this class have been launched and deployed by People's Liberation Army Navy North Sea Fleet. Background The construction of the Luzhou-class destroyer at China's northern Dalian Shipyard was revealed in 2004 with the help of Internet photographs. A disadvantage of the Type 051C is that it lacks the stealthier radar cross-section found on the newer Chinese warships. The ship also possesses less advanced steam turbine propulsion compared to gas turbine propulsion present in all newer Chinese destroyers. The Type 051C is a stop gap measure to provide long range area air defense to the fleet by mating the mature hull design with ...

Guangzhou Class Destroyer
The Type 052B (NATO/ OSD Luyang I-class destroyer is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy Surface Force (PLAN). The Type 052B was China's first modern destroyer designKirchberger (2015): page 195McDevitt (2017): page 57 and the first Chinese design to incorporate true medium-range air defence capability in the form of Russian Shtil-1 (improved navalized Buk, NATO designation SA-N-12) surface-to-air missiles (SAM).Schwartz (2015): page 26 Two ships - ''Guangzhou'' and ''Wuhan'' - were built and commissioned in July 2004. Programme In the early 2000's, China pursued multiple - and sometimes concurrent - programmes to acquire modern destroyers, purchasing s from Russia and constructing the Type 052B, Type 051C, and Type 052C.Kirchberger (2015): page 193 These ships also represented steps to develop adequate air defense capabilities by adopting Russian air defense technology.;Schwartz (2015): pages 25 the 25-km range Uragan (navalized ...

Lanzhou Class Destroyer
The Type 052C destroyer (NATO/ OSD Luyang II-class destroyer) is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy Surface Force (PLAN). The Type 052C introduced both fixed active electronically scanned array (AESA) radar and vertically launched surface-to-air missiles into PLAN service,McDevitt: pages 59-60 making it the first Chinese warship with area air defence capability. , six of these destroyers had been built and were operational. Program The first two ships, and , were laid down at the Jiangnan Shipyard in Shanghai in 2002, and entered service in 2004 and 2005 respectively. No new ships were laid down until 2010;Li: page 44 the pause may have been due to the relocation of the shipyard.McDevitt: pages 59 Design The Type 052C appears to share the same basic hull design as the Type 052B destroyer, which in turn is based on the Type 051B destroyer. Stealth features are incorporated. The Type 052C uses predominantly Chinese systems deri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ma'anshan Class Frigate
The Type 054 (NATO Codename Jiangkai I) is a class of Chinese multi-role frigates that were commissioned in the People's Liberation Army Navy Surface Force in 2005. They superseded the Type 053H3 frigates. Only two ships, ''Ma'anshan'' (525), and ''Wenzhou'' (526), were completed before production switched to the VLS equipped improved Type 054A frigate. Design The Type 054 has a stealthy hull design with sloped surfaces, radar absorbent materials, and a reduced superstructure clutter. The main anti-ship armament were YJ-83 sea-skimming anti-ship cruise missiles in two four-cell launchers. It retained the HQ-7 SAM, an improved version of the French Crotale, from the preceding Type 053H3; the HQ-7 had a ready-to-fire 8-cell launcher, with 16 stored in the automatic reloader. Short range defence was improved with four AK-630 CIWS turrets. A 100 mm main gun, also based on a French design, was mounted. Both ships were powered by four CODAD Type 16 PA6 STC marine diesel engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Radars
The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers approximately 71% of the Earth's surface. The word sea is also used to denote second-order sections of the sea, such as the Mediterranean Sea, as well as certain large, entirely landlocked, saltwater lakes, such as the Caspian Sea. The sea moderates Earth's climate and has important roles in the water, carbon, and nitrogen cycles. Humans harnessing and studying the sea have been recorded since ancient times, and evidenced well into prehistory, while its modern scientific study is called oceanography. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. Salinity varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary li ...
