Decision was made to have a new class of minesweeper based on the technical experience gained from both classes, along with lessons learned from the deployment of Type 312 minesweeper in North Vietnam, and this is the origin of 082 minesweeper. Specifications:Īlthough both Type 058 and Type 7102 minesweepers met their requirements, the backwardness of Chinese industrial and manufacturing capabilities limited both classes from being mass produced, resulting in only 20 Type 058 minesweeper and a single Type 7102 minesweeper being built.

For mine clearing operation, a specially designed Type 6135 generator with 1850 rpm was adopted, and Type 7102 minesweeper won an award from National Science Conference in 1978.

From April to September 1975, a lengthy trial was conducted in Yangtze River and Wusong, and the boat finally entered service in November 1975. Construction begun at Wuhu Shipyard in May 1972, and after two years, it was launched in December 1974.

The other minesweeper resulted from PLAN's request of building riverine and gulf minesweeper constructed with low magnetic signature is Type 7102 minesweeper, which is constructed with fiberglass.

Propulsion: two M50F-4 and two 12D6 diesel engines, 4220 hp total.

Max sea state allowed for minesweeping: 4.

Min width of mine clearing path: 20 meter.

Max width of mine clearing path: 100 - 120 meter.

This first unit and subsequent units were immediately sent to North Vietnam to clear mines laid by USA in the following year. Type 058 minesweeper was the first Chinese low magnetic minesweeper in service, and construction of the first unit of this class begun in July, 1970, launched two months later in September 1970, and entered service in on December 12, 1970. The shipyard spent huge research effort and concluded that these micro cracks would not affect the strength and performance of alloy, and the project was able to continue. The biggest problem was that when this type of alloy was heated, it often left cracks behind in welding. The program experienced huge difficulties because the manufacturing technique of low magnetic steel, which was a type of manganese - aluminum - iron alloy. Design of Type 058 minesweeper was completed by the 708th Research Institute and China Shipbuilding Shipyard at Shanghai (上海中华造船厂) begun construction of Type 058 in the same year.

The origin of Type 082 series mine countermeasure vessel can be traced back all the way in November 1967, when People's Liberation Army Navy (PLAN) issued an request of building riverine and gulf minesweeper constructed with low magnetic signature, which resulted in two minesweepers developed, one of which was Type 058 minesweeper.

It is also known as Wosao class in the west, but the correct Chinese name is actually Wusao, short for armed ( Wu-zhuang, 武裝) mine sweeping boat ( Sao-lei-ting, 掃雷). The Type 082 class minesweeper is a Chinese People's Liberation Army Navy ship class.
