Chamsuri class patrol vessels are naval boats that function as patrol craft. These entered service with the South Korean navy (South Korea) in the 70s, and have since seen service with three other navies, of which the Philippine Navy is currently the largest non-South Korean user.

These boats were built by the Hanjin Industrial SB, Chinhae, and Korea SB & Eng. Masan shipyards.^[2]

These boats, also referred to as "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 1 40-mm Bofors 60-cal Mk.3; 1 twin 30-mm 75-cal Emerlec EX-30; 2 single 20-mm 70-cal. Mk. 10 AA. Late PKM 201 boats were armed with 1 twin 30mm 75-cal Emerlec EX-30 AA; 1 or 2 single 20-mm Vulcan gatling AA; 2 single 12.7-mm machine guns. The PKM 301 boats were armed with one 40mm 60-cal Bofors AA in a fully enclosed mount; 2 single 20-mm Vulcan gatling AA; 2 single 12.7mm machine guns.^[2]

As newer, more capable patrol craft enter South Korean navy service, the Chamsuri class boats are slowly being retired.
