Chamsuri-class patrol vessels (Hangul: 참수리급 고속정) are naval boats that function as patrol boats. These entered service with the South Korean navy in the 1970s, and have since seen service with three other navies, of which the Philippine Navy is currently the largest import user.


These boats were built by the Hanjin Industrial SB, Chinhae, and Korea SB & Eng. Masan shipyards.

These boats, also referred to as patrol killer medium "PKM", were built in two batches: the 201 series, and the more heavily armed 301 series. Early PKM 201 series boats were initially armed with one 40-mm Bofors 60-cal Mk.3, one twin 30-mm 75-cal Emerlec EX-30, and two 20-mm 70-cal. Mk. 10 AA. Late PKM 201 boats were armed with one twin 30mm 75-cal Emerlec EX-30 AA, one or two single 20-mm Vulcan gatling AA, and two single 12.7-mm machine guns. The PKM 301 boats were armed with one 40mm 60-cal Bofors AA in a fully enclosed mount, two single 20-mm Vulcan gatling AA, and two single 12.7mm machine guns(before 2nd yeonpyeong sea battle 2×M60 .30cal machinegun.

The Chamsuri class boats are slowly being retired and replaced by Gumdoksuri-class patrol vessel in South Korean Navy.

    One naval and two coast guard units were transferred by South Korea to the Naval Component of East Timor's F-FDTL in September 2011, apparently on the basis of a transfer agreement signed in Seoul the previous month. They have been rechristened Kamenassa, Dili and Hera, respectively. Sub-class and original pennant numbers are currently unknown.

An additional two ships, PKM 223 and PKM 232, were acquired in 2006.
