Yung Yang (Agile) class mine countermeasures vessels
Yeongyang class ocean minesweepers built in the United States in the 1950s enterprising class ocean minesweepers. Originally during the Korean War,to counter the North Korean coast in a large number of laying mines designed and built, before the transfer to Taiwan's navy has conducted a large-scale modification,equipped with more advanced equipment. Yeongyang-class housing is divided into 3 layers, with high-quality wood hull is very strong and elastic.
Shipboard machinery and equipment use non-magnetic stainless steel, copper and other materials, the host of quieter, so the sound hull itself is very small magnetic and other physical characteristics. Yeongyang level is the maximum displacement of Taiwan's navy, the performance of more advanced, the only ocean-going mine-clearance capacity with the anti-mine ships.
These ex-US Navy ships were extensively overhauled following transfer. In the early 90s, Taiwan authorities had purchased four modernized mine hunters from Germany. On July 12, 1991, four "MWW50" mine hunters were formally put into service in Taiwan navy's Zuoying base, becoming a modern mine-sweeping force of Taiwan's navy.
These four mine hunters and another four US-made MSO ocean mine-sweepers together formed into the 236 combat force, placed under the jurisdiction of 192 sea fleet (mine fleet), which mainly undertake the task of clearing mines in the periphery of several key ports and sea traffic lines. These four mine hunters, designed and made by a German company, and sold at a cost of nearly 100 marks each, are the most advanced mine hunters of Taiwan's navy. The mine hunter is equipped with high-tech searching radar and active underwater sonar, what is most special of it is that it is equipped with a commonly called PB3 underwater processor, underwater surveillance and mine-sweeping action can be carried out by the remote-control method, thus dramatically raising mine-sweeping safety.
Taiwan's annual foreign ocean shipping volume approaches 200 million tons, the majority of which are undertaken by several important ports in Kaohsiung, Keelung, Hualien and Su'ao, so whether sea-routes are smooth or not is vitally important to Taiwan. The depth of water in Taiwan's surrounding sea areas ranges mostly between 50-60 meters, this makes it easy for the large-scale deployment of mines. Hualien and Su'ao ports in the eastern part of Taiwan, in particular, because they face the vast Pacific Ocean, it is fairly hard to impose blockade by forces, it is more possible for blockade by dense mine formation.
