First ship of the class, ROKS Daegu, was built by DSME. It was launched in June 2016 and commissioned with the ROK Navy on March 6, 2018. Second ship of the class, ROKS Gyeongnam was launched in June 2019 and was built by DSME as well. The third FFX Batch II Frigate, ROKS Seoul, was launched in November last year. The third and fourth frigates of the class were built by HHI.

A total of 8 frigates of this class, also known as the Incheon-class batch II or FFG-II , are set to be built by both DSME and Hyundai Heavy Industries, for the South Korean fleet.

ROKS Donghae is set to be commissioned with the ROK Navy at the end of 2021. A program to build the third batch (FFX III) frigates which will displace over 3,000 tons and feature a phased array radar is also underway. HHI announced last month that it signed a contract for the detailed design and construction of the 3,500 ton FFX Batch III frigate.

According to the ROK Navy, the new frigate features “advanced sonar and power systems to boost anti-submarine capabilities in coastal operations”. The SQR-250K TASS, low frequency passive sonar system is used for detecting, identifying and tracking enemy submarines. Its hybrid propulsion system reduces underwater radiation noise, which greatly enhances the anti-submarine ability of the vessel.
