The Chamsuri class (Korean: 참수리급 고속정) (also known as the "Sea Dolphin" and "Wildcat" types)^[1] are patrol boats originally constructed for and operated by the Republic of Korea Navy. They first entered service in 1979, and they have since seen service with five other navies, of which the Philippine Navy is currently the largest import user. These boats were built by the Korea Tacoma, and Korea SB & Eng. Masan shipyards. In Korea, the Chamsuri-class boats are being retired and replaced by Gumdoksuri-class patrol vessels.
