Its main missions are gathering data of ports in the Korean region, and searching naval mine and minesweeping, in wartime.[4] They sometimes used at finding and recovering North Korean missiles, by using Variable Depth Sonar to detect missile fragments.[5][6]
Ongjin, second ship of the class, is famous for finding the stern of ROKS Cheonan at the site of the ROKS Cheonan sinking.[7]
History edit
At the Korean War, Korea did not have proper minesweeping equipment, and it was all about pulling naval mines out of fishing nets or blowing up floating mines with light machine guns. Therefore, North Korea inflicted massive damage by the naval mine.[8] In the 1980s, Korea developed and used 6 Ganggyeong-class minehunters, which were the base of Yangyang-class ships.[1]
In the 1990s, the Navy made an upgraded minehunter design, based on the Ganggyeong-class. The first ship was launched and commissioned in 1999, which was named Yangyang. Two more, Ongjin and Haenam, were launched a few years later. Compared to Ganggyeong-class, Yangyang-class ships improved minesweeping ability, and increased hull size.[1]
Design edit
Yangyang-class ships are 60 metres (196 ft 10 in) long, 10.5 m (34 ft 5 in) wide. They are equipped with Multi-purpose machine gun,[4] a 20 mm (0.8 in) main gun, and Mine Disposal Vehicle (MDV). They use two Voith Schneider Propellers as propulsion, to control the ship more precisely. To perform minesweeping activities, mechanical/inductive minesweeping device and sonars are equipped.[1]
Officially about 50 crew are boarding the ship.[3]
Hull material edit
To protect the ship from magnetic mine, the ship's hull is made of fibre-reinforced plastic, which does not have a magnetic attraction, and lasts longer than commonly used material. It also minimized metallic equipment to tightly control the magnetic material inside the ship. Steel objects that are brought into the ship, like canned food, are heavily restricted and strictly controlled.[1]
Naming edit
The naming of minesweeper ships is taken from the names of counties and towns adjacent to a naval base.[3] For example, Yangyang is the name of Yangyang County, Gangwon Province.
