Chamsuri II (PCFG)

The Chamsuri II (PKX-B) class is a modern series of patrol boats developed for the Republic of Korea Navy, designed to replace the aging Chamsuri-class vessels. These fast attack craft are equipped for coastal defense and interdiction, featuring advanced weaponry and improved stealth capabilities.

Developed under the PKX-B program to counter North Korean high-speed hovercraft and maritime infiltration threats along the Northern Limit Line (NLL), the Chamsuri II class was designed with a heavy emphasis on automated precision firepower. The lead vessel of the class, Chamsuri 211, was launched by Hanjin Heavy Industries in 2016 and officially entered service with the Republic of Korea Navy in November 2017. Since their introduction, these craft have been actively deployed in the West Sea, where they routinely patrol disputed waters and utilize their advanced 130mm guided rocket systems for rapid-response defense. Currently, the ROK Navy continues to commission subsequent hulls of the class, cementing the Chamsuri II as a cornerstone of South Korea's modern littoral defense strategy.
