The Chamsuri Class patrol craft was developed by Korea Tacoma Marine Industries. The boats first entered service with the Republic of Korea Navy (ROKN) in the 1970s. The craft are built by Korea Tacoma Marine, Hyundai Heavy Industries and Hanjin Heavy Industries.

Chamsuri Class boats are also known as Patrol Killer Medium (PKM) craft. The boats were built in two batches known as the 201 series and the 301 series. In addition to the ROKN, the patrol boats are also in service with the Bangladesh Navy, Kazakhstan Navy and the Philippine Navy.

South Korea has also transferred seven patrol craft to the Philippine Navy. The first batch of five boats were delivered in 1995 and a second batch of two craft were transferred in 2006. The Philippine Navy boats are designated as the Tomas Batillo Class. These boats are deployed to protect the Malampaya natural gas platforms near Palawan.

The Philippine Army with the Constabulary as a nucleus was formed, with different branches of services like infantry, artillery, etc., of the US Army, a sea-going branch called Off-Shore Patrol (OSP) and an Air Corps as branches of service.

The OSP was a part of National Defense Act approved on 21 December 1935 and, on 11 January 1936, the guidelines were denned by Executive Order No. 11 as follows:

"The Off-Shore Patrol shall comprise all marine equipment and personnel acquired by the Philippine Government and assigned either in peace or war to the control of the Chief of Staff (PA). It shall have such duties and powers as may be described by the Chief of Staff, PA."

On 15 April 1938, when construction of two MTBs for the OSP was started by Thornycroft, Maj. Rafael Ramos, a Philippine Nautical School (PNS) graduate known to Quezon, was appointed as first OSP Chief to start recruiting OSP personnel. Brigadier General Vicente Lim, G-1, HPA furnished him a list of Annapolis and PNS PA officers to select from but he was unable to do anything because Rep. Manuel Roxas recommended to Pres. Quezon that his province mate, Capt. Jose V. Andrada, USNA 1930, was better qualified. And so Capt. Andrada relieved Maj. Ramos as OSP Chief who was sent to the US QM School to study.

Captain Andrada announced his volunteer recruiting program and began interviewing interested individuals personally. By the end of 1938, Lt. Alfredo Peckson, USNA 1933, Lt. Marcelo Castillo, USNA 1938, PCA graduates Lieutenants Nestor Reinoso 1934, Alberto Navarette 1935, Simeon Castro 1935, Juan Maglayan 1937, Alfonso Palencia 1938, Santiago Nuval 1938, Emilio Liwanag 1938 and nine officers and 25 enlisted men had joined the OSP. Training on seamanship, navigation and gunnery were conducted with the USNA graduates as instructors at OSP Hq., Muelle del Codo, Port Area, Manila. The first class graduated on 9 February 1939, and Capt. Andrada marked it as the birthday of the OSP and since then, as far as I know, our anniversary is celebrated every 9 February, until somebody during the Martial Law years of Marcos tampered with the event.
