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.

The Bangladesh Navy operates 4 PKMs. The first two (P1011 and P1012) were transferred from South Korea in 2000. Another two (P1013 & P1014) entered service in 2004.[4]
Three vessels were transferred by South Korea to the Naval Component of East Timor's F-FDTL in September 2011[5], apparently on the basis of a transfer agreement signed in Seoul the previous month.[6] They have been rechristened Kamenassa, Dili and Hera, respectively. Sub-class and original pennant numbers are currently unknown.
One vessel transferred in 2011.
Timor Leste received one Chamsuri (Sea Dolphin) class patrol boat and two Seagull class missile boat.
Kazakhstan received 3 PKMs in 2006. These were purchased for a token amount of $100 per ship.[7]
At least 7 PKMs were transferred to the Philippines. The first 5, PKM 225, 226, 229, 231, and 235, were transferred in 1995. Three were commissioned the following year, with the remainder used as cannibalization spares. An additional two ships, PKM 223 and PKM 232,[8] were acquired in 2006.[9]
PKMs in Philippine Navy service are collectively referred to as the Tomas Batillo class, named after Filipino officers & soldiers who served with distinction during the Korean War. These are listed below[3]:
