The Sri Lanka Navy (SLN) (; ) is the naval arm of the Sri Lanka Armed Forces and is classed as the country's most vital defence force due to its island geography. It is responsible for defending the maritime borders and interests of the Sri Lankan nation. The role of the Sri Lanka Navy is to conduct operations at sea for the defence of the nation and its interests and conduct prompt and sustainable combat operations at sea in accordance with the national policies.

Sri Lanka, situated in the middle of major sea lanes passing through the Indian Ocean, was always a magnet for seafarers and has a long history of naval campaigns. The current Sri Lankan Navy was established on 9 December 1950 when the Navy Act was passed for the formation of the Royal Ceylon Navy. The roots of the modern Sri Lankan Navy date back to 1938 when the Ceylon Naval Volunteer Force was established, which was renamed and absorbed into the Royal Navy as the Ceylon Royal Naval Volunteer Reserve during World War II. The current name, Sri Lanka Navy, was constituted in 1972 when Sri Lanka became a republic and with the introduction of new constitution.

It played a key role in the Sri Lankan Civil War, conducting surveillance and patrol, amphibious and supply operations. During the war, the navy moved from a small force focused on coastal patrols to a large combat force concentrating on asymmetric naval warfare capable of amphibious and land operations in support of counter-insurgency operations that progressed into engagements of a new form of littoral zone warfare. It carried out expeditionary deployments in the Indian Ocean in order to intercept rogue arm shipments on the high seas. The navy has its own elite special forces unit, the Special Boat Squadron.

The professional head of the navy is the Commander of the Navy, currently Vice Admiral Damian Fernando. The commander-in-chief of the Sri Lanka Armed Forces is the President of Sri Lanka, who heads the National Security Council; the Ministry of Defence is the organisation where ship buying policies are made for the navy. The Sri Lanka Navy has five Advanced Offshore Patrol Vessels (equivalent to a traditional patrol frigate), three Offshore Patrol Vessels, two missile boats, 40 fast attack crafts, more than 200 patrol boats, seven landing ships/craft, along with six auxiliary vessels.

History The beginning and World War II

In January 1938 the Ceylon Naval Volunteer Force (CNVF) was created with Commander W.G. Beauchamp as Commanding Officer under ordinance No I of 1937. On 31 August 1939 at the outset of World War II, the CNVF was mobilised for war duties. It took part in action during the Easter Sunday Raid. Three years later, the CNVF was offered to, and accepted by the Royal Navy (RN) as a Volunteer Reserve, the Ceylon Royal Naval Volunteer Reserve (CRNVR). It continued under Royal Navy operational and administrative command until March 1946. With the end of the war, it reverted to Ceylon Government control, though yet CRNVR in name. In the 1939–1946 period, the CRNVR carried out several operational duties, mainly at sea. Cutting its teeth on the Port Commission tugs Samson and Goliath, it later crewed and operated trawlers and Antarctic whalers converted as minesweepers and fitted out with guns, submarine detection equipment and anti-submarine weaponry. They were HMS Overdale Wyke (the first ship to be purchased by the Government of Ceylon), HMS Okapi, HMS Semla, HMS Sambhur, HMS Hoxa, HMS Balta and HM Tugs Barnet and C 405. In addition the CRNVR crewed nned several Motor Fishing Vessels (MFV), Harbour Defence Motor Launch (HDML) and miscellaneous auxiliary vessels. All were crewed exclusively by CRNVR personnel. These ships were meant to sweep and guard the approaches the harbours but were often used on extended missions outside Ceylon waters. In the course of these operations, the ships came under enemy fire, recovered essential information from Imperial Japanese aircraft that were shot down, sailed to Akyab (modern Sittwe) after the Burma front was opened in two FMVs for harbour duties, and were called upon to accept the surrender of the Italian sloop Eritrea and escort her to the Colombo port with a prize crew on board.

Royal Ceylon Navy

Formation With Ceylon gaining self-rule from the British in 1948, the Parliament of Ceylon passed the Navy Act, No. 34 of 1950 which established the Royal Ceylon Navy (RCyN) on 9 December 1950. The CRNVR served as a source of officers and sailors for the newly established RCyN as one hundred were selected and transferred to the regular naval force. Under the Navy Act, the CRNVR became the volunteer naval force on 9 January 1951 as the Royal Ceylon Volunteer Naval Force (RCVNF). The first warship of the RCyN was commissioned in 1951 as HMCyS Vijaya, an Algerine-class minesweeper, ex-HMS Flying Fish along with other patrol boats and tugs. It was the policy of His Majesties Government of Ceylon to build a strong navy to be the first line of defence of the island country. As such the fleet was expanded with the addition of, HMCyS Parakrama, another Algerine-class minesweeper (ex-HMS Pickle), two Canadian-built "River" class frigates HMCyS Mahasena (ex-HMCS Orkney, Violetta and ex-Israeli ship Mivtach), HMCyS Gajabahu (ex-HMCS Hallowell, ex-Israeli Misnak) and an oceangoing tug (ex-HMS Adept). The RCyN took part in several joint naval exercises and a goodwill missions. Commodore Royce de Mel became the first Ceylonese to head the navy as he was appointed Captain of the RCyN in 1955. In 1959, the navy took over the strategic Royal Naval Dockyard, Trincomalee as the last of the British forces in Ceylon withdrew. In 1960, flexing its blue water capability a naval fleet undertook a deployment to the far east. Its return resulted in scandal as a search for contraband took place. A Commission of Inquiry into the incident resulted in the dismissal of several officers (with commissions withdrawn and others retired) and the compulsory retirement of Rear Admiral de Mel, who was thereafter implicated in an attempt military coup d'état in 1962.

Stagnation In the aftermath of the attempted coup, the armed forces saw major budget cuts that dramatically halted the expansion it enjoyed in the 1950s. Under N. Q. Dias, the Ministry of External Affairs and Defence changed its defence policy taking steps to prevent a further coup attempts. Joint operations among armed services were stopped, with the army to focused on internal security and the role of the navy was scaled down. As a result, several of its ships were sold off and its size reduced by the stoppage of recruitment of officers cadets and sailors for over seven years, the loss of important bases and barracks and the stoppage of training in the United Kingdom. Two batches of 300 ratings were recruited in 1966 and 1969.

Insurrection

As a result, in 1971 the navy was poorly equipped and short of personnel when the 1971 JVP Insurrection broke out. RCyN had only one warship, HMCyS Gajabahu which was not put to sea as its crew were dispatched with other naval personnel for shore duty. RCyN initially mounted the defence of ports and thereafter carryout offensive counterinsurgency operations against the insurgents. During the insurrection navy suffered its first combat casualties and went on to man detention centres to rehabilitate surrendered insurgents after it was crushed in a few months. Ceylon, however, had to rely on the Indian Navy to established an exclusion zone around the island.

With the JVP insurrection, the Government felt the limitations of the RCyN and the need to strengthen the navy. The People's Republic of China gifted two Type 062-class gunboat and these were commissioned in February 1972, while three more were ordered.

Navy of the Republic

In July 1972 the "Dominion of Ceylon" became the "Democratic Socialist Republic of Sri Lanka" and the Royal Ceylon Navy became the Sri Lanka Navy. The ensign, along with the Flag Officers' flags, were redesigned. The term "Captain of the Navy", introduced in the Navy Act, was changed to "Commander of the Navy", in keeping with the terminology adopted by the other two services. Finally, "Her Majesty's Ceylon Ships" (HMCyS) became "Sri Lankan Naval Ships" (SLNS).

SLN received three more Type 062-class gunboats in December 1972, while the USSR gifted a Shershen-class torpedo boat in 1975. These gunboats allowed the SLN to carry out effective coastal patrolling and several cruises to regional ports. New bases were established to counter smuggling operations in the coastal areas. Five inshore patrol crafts were ordered from Cheverton, while six coastal patrol craft were built by the Colombo Dockyards.

Civil war

At the begin of the civil war in the 1980s the navy found itself poorly equipped to face the new threats the LTTE created. It found itself engaging in anti-smuggling operations to counter LTTE gun running between India and Sri Lanka. As the larger gun boats proved ineffective against faster small boats used by the LTTE with outboard motors, the navy began deploying small boats with waterjets and inshore patrol boats armed with machine guns to police its waters. The LTTE responded with mounting machine guns and attacking the navy boats. This began an asymmetric war at sea, taking place primarily in the coastal waters among small boats of the navy and the LTTE naval arm the Sea Tigers. The decades long conflict saw the escalation of the size, firepower and speed of the boats with new techniques deployed by both sides. The Sea Tigers mastered the art of using sophisticated suicide crafts against naval vessels both small and large. The navy acquired in the late 1980s Israeli Dvora-class fast patrol boats which it designated as Fast Attack Crafts (FAC). The FACs of the Fast Attack Flotilla became the workhorses of the navy's offensive and defensive operations against the Sea Tigers. In the 1990s and 2000s Super Dvora class boats were added and a locally built Colombo class was introduced in larger numbers. These proved highly successful in limiting the LTTE's use of the seas.

During the war the navy increased its fleet of larger vessels by introducing two locally built Jayasagara class offshore patrol vessels and purchasing several more Type 062-class gunboats. The navy lost several ships in the 1990s to Sea Tiger attacks by suicide crafts such as in the sinking of SLNS Sagarawardena and SLNS Ranaviru and the use of suicide frogmen such as in the bombing of SLNS Sooraya and SLNS Ranasuru. Due to the threat posed by the Sea Tigers, the navy had to undertake convoy duty to escort shipping to the Jaffna peninsula to which all land routes were controlled by the LTTE. In order keep supply lines open to Jaffna, the navy employed several auxiliary ships. It also deployed auxiliary ships to support FACs.

In the early 1980s a land combat force named Naval Patrolmen was created which at first limited itself to base defence and, as its numbers increased, took part in offensive operations against the LTTE along with the Sri Lankan Army. An elite naval special forces unit called the Special Boat Squadron was created in the late 1980s based on the British Special Boat Service.

In order to support ground operations of the army, landing ships and boats were acquired. In early 1990s the SLN carried out in conjunction with the army its first amphibious operation code named Operation Sea Breeze followed by the larger Operation Balavegaya a year later and on the seas it began an aggressive clamp down on LTTE actives including gunrunning. In 1992, Admiral W.W.E. Clancy Fernando, the commander of the navy was assassinated by a suicide bomb attack by the LTTE.
