Donghae-class corvette

The Donghae class (동해급) corvette is a class of four ships of the Republic of Korea Navy used for coastal patrol duties. Each corvette is armed with one Oto Melara 76 mm compact gun, three AA guns, six torpedoes and twelve depth charges for anti-submarine operations. The ships resemble the later Pohang-class corvette, but have slightly different armament.

Each ship was built by a different shipbuilder. ROKS Donghae (PCC-751) was the first to be launched, in 18 November 1982, and ROKS Anyang (PCC-755) the last in 1983. Each ship is named after a Korean city while Donghae is a port city itself.
