The
Royal Khmer Navy (, MRK) was officially established on 1 March 1954, to provide limited patrolling of Cambodia's maritime coastline and territorial waters, monitoring the security of its main deep-water ports and major waterways. The MRK was formed with an initial strength of just 600 officers and enlisted men placed under the authority of
Captain ()
Pierre Coedes, a naval officer of mixed French-Cambodian origin, who acted as Chief of Naval Operations (). They crewed a handful of
World War II-vintage ex-
French Navy vessels transferred to Cambodia at the end of the
First Indochina War: British-made
Harbour Defence Motor Launches (), U.S.-made
Landing Craft Vehicle Personnel (LCVP) and
LCM (6) Landing Crafts. Most of the MRK's naval assets and personnel, together with its administrative headquarters, were harboured at the former French colonial riverine station situated in the
Chrui Chhangwar Peninsula () across the
Tonle Sap river from
Phnom Penh. However, the tiny facilities proved so inadequate that the Navy HQ was allocated aboard an old French-made riverine vessel named
La Payotte, permanently moored at Chrui Chhangwar base.
Early expansion phase 1955–1964 Closely modelled after the Naval and riverine component of the
French Far East Expeditionary Corps (CEFEO), the MRK received training, technical and material assistance primarily from France and the United States. At first, the Cambodian naval service continued to expand rapidly under French auspices between 1955 and 1957 – at this stage, a
French Military Mission in Cambodia helped in the renovation or construction of new harbour facilities, provided technical assistance and training programs, and supervised equipment deliveries. The MRK also began to receive additional assistance from the United States
Military Assistance Advisory Group (U.S. MAAG) aid program, established since June 1955 at Phnom Penh. The cramped Chrui Chhangwar base was modernized and enlarged to accommodate a new dock designed for large-sized riverine vessels and a
Naval Training School (), established in January 1955 to train ship crews and other specialized personnel. The MRK had no
naval academy at the time, so Khmer officer candidate students ( – EOM) were sent to France, in order to attend advanced Officer courses at the
French Naval Academy in
Brest. A new coastal naval base was constructed at
Ream in
Kampot Province, near the newly built port city of
Sihanoukville (rechristened
Kampong Som in 1970), equipped with a
floating dock whilst the Cambodian Navy's tiny surface fleet was augmented at the time by the addition of fifteen sea and river crafts of British and U.S. origin donated by the French government. Deprived of further American support, the MRK continued to rely on the French military mission to provide both vital basic and technical training for its own naval personnel, receiving thereafter some aid from China and
Yugoslavia. Between 1965 and 1969, these latter countries delivered three s and two
TC-101 torpedo boats (the latter soon rendered unserviceable due to accidents and natural disasters), whilst France provided an
EDIC III-class Landing craft tank (LCT) for coastal transport duties. As with the other branches of the then FARK, the Cambodian Navy's own military capabilities in the late 1960s remained low and the missions that they performed mirrored those of a peacetime River Police force or
Coast Guard rather than a true Navy. Therefore, MRK activities were restricted to inland patrols on the
Bassac River, the
Mekong, and the
Tonle Sap River in the vicinity of the namesake Great Lake whilst high seas operations were limited to routine inshore patrolling in the
Gulf of Thailand.
Pre-1970 fleet organization MRK strength in February 1970 stood at about 1,600 Ratings and seamen under the command of Captain
Vong Sarendy, who crewed a small fleet comprising two flotillas (one sea and one riverine) and a training squadron.
Reorganization 1970–1972 Re-designated
Khmer National Navy ( – MNK) on 9 October 1970, the Cambodian Navy and its fleet were given responsibility for escorting supply convoys on the lower Mekong-Bassac corridors. Such operations were carried out in conjunction with the
Khmer Air Force (KAF), which began to provide since mid-1971 air cover to MNK convoys with their
Douglas AC-47D Spooky gunships and later
AU-24A Stallion mini-gunships. In addition, the Navy also provided logistic support (including troop transport and casualty evacuation) for the FANK ground forces. Shortly after the
March 1970 coup, however, the
French military mission suspended all the cooperation with the Cambodian armed forces, thus depriving the new MNK of vital training and technical assistance. During this phase, the MNK was assisted in its new roles by the South Vietnamese Navy, which lent extensive convoy protection to riverine commercial shipping and helped patrol the Cambodian coastline to prevent North Vietnamese infiltration attempts. The MNK underwent a major reorganization program in late 1970, with the creation of two operational zones: a
Riverine Region ( or RegFlu) headquartered at Chrui Chhangwar and a
Maritime Region ( or RegMar) headquartered at Ream; a
Mekong Special Zone ( – ZSM; later
12th Tactical Zone or
Zone Tactique 12), also headquartered at Chrui Chhangwar was created in mid-1971 at
Kandal Province, situated between the Cambodian Capital and the South Vietnamese border. The Sea Patrol Force and the Training Squadron remained untouched by these changes, though the Riverine Patrol Force was re-organized into three squadrons – the river patrol craft under the
Riverine Patrol Division ( – DPF), the landing craft under the
Assault Division () and the transport vessels under the
Logistics Support Group ( – GSL). These new formations, together with the Naval Infantry battalions, were under the direct command of Captain (promoted to
Commodore in December 1971)
Vong Sarendy, who in turn reported directly to the FANK Chief-of-Staff for operational orders. As the newly restructured MNK had gained by late 1971 enough experience to commence its own escort and combat patrol operations, an expansion of its naval assets and support facilities, and training establishments was therefore deemed necessary. The two pre-existing Naval Bases were once again upgraded, while another two riverine stations were established on the lower Mekong corridor at
Neak Leung in Kandal Province, and at the provincial capital of
Kampong Chhnang, on the Tonle Sap River. By January 1972 the MNK had expanded to 5,500 men, this number including 430 officers, although only 23 of them held the rank of
Lieutenant commander or higher, and these were showing signs of fatigue due to over-work. To alleviate this problem, an input of 14 Cambodian officers were sent to the United States to attend advanced courses at various U.S. naval training institutions. Eight students attended the
U.S. Naval Academy (USNA) at
Annapolis, Maryland, whilst two senior officers went to the
Naval War College (NWC) in
Newport, Rhode Island and the
Navy Supply Corps School (NSCS) in
Athens, Georgia; four other students attended the small boat tactics school at the
Mare Island Naval Shipyard (MINSY) and the adjacent
Naval Inshore Operations Center at
Vallejo, California.
Harbour defense and special operations Following several attacks against merchant vessels anchored at
Chrui Chhangwar Naval Base in early 1972, the MNK Fleet Command created a regimental-sized Harbour Defense Unit, the
"Strike Commandos" () comprising two rifle battalions, to patrol its major port facilities and provide VIP protection, equipped with an assortment of outdated and modern U.S. and captured Soviet or Chinese small-arms. The
1st Strike Commando Battalion ( – 1 BCC) and
2nd Strike Commando Battalion ( – 2 BCC), based respectively at Chrui Chhangwar and Ream, were supported on their duties by the Naval Infantry, who performed active riverbank patrolling. An American-trained
SEAL unit was raised in mid-1973, being employed on reconnaissance missions along the banks of the Mekong and as shock troops on amphibious operations, and was subordinated to the MNK
Amphibious Operations Command (
French:
Commandement des opérations amphibies – COA).
Fleet Command Emulating its South Vietnamese parent organization, the Cambodian Navy's Fleet Command was placed under the authority of the MNK Chief of Naval Operations, who was responsible for the readiness of all sea and river craft. The Fleet Commander assigned and scheduled vessels to operate on the Riverine and Maritime Regions, and the Mekong Special Zone, the latter turned over to the Cambodian Army Command in February 1975, which were home ported in Chrui Chhangwar and Ream naval bases and normally returned there after concluding their assignments. On the field, the two regional and zone commanders assumed control of all naval or amphibious operations on their respective Regions, and the vessels under their command operated from the following interland or coastal ports: • Maritime Region – Ream/
Kampong Som/
Krong Koh Kong/
Krong Kep • Riverine Region – Chrui Chhangwar/Kampong Chhnang/Kampong Cham • Mekong Special Zone – Phnom Penh/Neak Leung
Expansion 1973–74 In 1970 the Cambodian Navy had only eleven vessels in serviceable condition, including two ageing PC-461-class Patrol Craft, three LSSLs, one LSIL, one LCI, one LCT and a few armed fishing junks to patrol both the coastline and its waterways. The remaining 10,000 or so sailors and ratings crewed a surface fleet of 178 vessels of various types, though consisting mostly of patrol, coastal, and amphibious crafts. ==Shipyards and repair facilities==
