Type 751 Radar
Type 751 radar is a Chinese navigational radar used by Chinese merchant ships and ships of Chinese navy, and it is the first navigational radar developed by Shanghai 4th Radio Factory, which subsequently also developed many other Chinese navigational radars after this humble beginning. Development begun in October 1963, with a design team led by the deputy general engineer Mr. Zhang Yuan-Zhen (张元震) and Engineer Gu Xie-Xiang (顾燮祥). First sample was completed by the end of 1964, and in September 1965, the radar was installed on the Chinese naval ship Luoyang (ex-HMAS Bendigo (J187)). The original antenna of Type 751 radar was parabolic, and later a slotted array was also developed in the later production stage. The maximum range is 48 nautical miles, and it utilizes a 31 cm display. The radar can be integrated to electronic support measures and IFF. To support the urgent production need, Qingdao 3rd Radio Factory was also tasked with the production. By the end of pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HMAS Bendigo (J187)
The first HMAS ''Bendigo'' (J187/B237/A111) was a minesweeper, a group commonly known as corvettes and including escort and patrol duties along with minesweeping. Design and construction In 1938, the Australian Commonwealth Naval Board (ACNB) identified the need for a general purpose 'local defence vessel' capable of both anti-submarine and mine-warfare duties, while easy to construct and operate.Stevens, ''The Australian Corvettes'', p. 1Stevens, ''A Critical Vulnerability'', p. 103 The vessel was initially envisaged as having a displacement of approximately 500 tons, a speed of at least , and a range of Stevens, ''A Critical Vulnerability'', pp. 103–4 The opportunity to build a prototype in the place of a cancelled saw the proposed design increased to a 680-ton vessel, with a top speed, and a range of , armed with a 4-inch gun, equipped with asdic, and able to fitted with either depth charges or minesweeping equipment depending on the planned operations: although closer ...

Naval Weaponry Of The People's Liberation Army Navy
The People's Liberation Army Navy (PLAN) is the naval branch of the People's Liberation Army (PLA), the armed forces of the People's Republic of China. The PLAN force consists of approximately 250,000 men and over a hundred major combat vessels, organized into three fleets: the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet. Most of the naval weapon systems used by the PLAN were developed prior to 1990. The naval weaponry of the PLAN is based on three tiers: artillery, torpedoes, and missiles, each geared to a specific threat range and type. History Throughout its early history from 1949 to the early 1980s, the PLAN had principally relied upon artillery and torpedoes as its main weapons. This resulted in the development of many types and calibers of anti-aircraft and anti-ship guns. Torpedoes were secondary weapons, playing an important role in PLAN's coastal defense doctrines. Many destroyers, frigates and torpedo craft all carry an array of anti-ship torpedoes to th ... [...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 ...
