The Sea Tigers (Tamil: கடற்புலிகள் ''Kaţaṛpulikaḷ'') was the naval wing of the

, 3 Warships, 2 Large Surveillance command ships, and one freighter. The Sea Tigers were led by Soosai, with their main base at Mullaitivu, on the north-eastern coast of Sri Lanka and their last base was taken when the Sri Lanka Army captured Chalai in Mullaitivu in February 2009.


Background

As the Tamil insurgency gained strength, the LTTE required that much of its supplies to be smuggled in by sea. It was soon realized that a naval component was needed to complement the land-based guerrilla forces. The leader of the LTTE, Velupillai Prabhakaran, understood the necessity of a naval force. The Sea Tigers were officially founded in 1984. In the first years its primary task was smuggling personnel and equipment between the LTTE's bases in Tamil Nadu and Sri Lanka, in particular Jaffna. As the Sea Tiger cadres gained experience, it took on offensive operations against the Sri Lankan Navy. The leader, 'Admiral', of the Sea Tigers was Colonel Soosai.

in the Spring of 2000, when some 2,500 cadres were landed behind enemy lines. Previously the largest such operation was the capture of Mullaitivu in 1996, in which the SLA lost over 1,200 soldiers with all their equipment. The LTTE admitted to losing 330 personnel during the latter operation. In August 1996, the Sea Tigers attacked a cargo vessel ''MV Princess Wave'' while it was loading Ilmenite from Pulmoddai, a tradinational Tamil homeland. 15 Sri Lankan Navy soldiers were killed in that attack. In May 1997, Sea Tigers sunken another cargo vessel by placing two to five kilograms of explosives in the hull (starboard or right side), below the water, just near the propeller. The vessel was a cargo vessel named ''Athena'' loaded with 42,000 metric tons of Argentinian wheat worth over Rs 570 million (ten million US dollars) In 2001, the Sri Lankan Navy launched the Operation "Varuna Kirana", to stop LTTE sea tiger convoys from retrieving weapons and equipment from LTTE smuggling ships in the open seas. However, this was ultimately unsuccessful. The SLN units were spread out, and frequently found themselves outnumbered by LTTE convoys, with 10-15 vessels in each caravan pitted against SLN vessels operating in pairs . The sea tigers also benefitted from weak intelligence gathering by the navy and the poor communications between the navy and the air force. Sea Tigers'

s and smaller suicide boats had engaged and sunk around 29 Sri Lanka Navy fast patrol boats. They also attacked the main SLN naval base in a suicide bomber vessel mission at Trincomalee and damaged one of the two SLN catamarans used as troop transports. On October 20, 2006, the Sri Lankan Navy reported that it had sunk 2 boats, and damaged several others in a major skirmish which reportedly left at least 20 rebels killed in the naval battle but not confirmed by the Sea Tigers. On November 1, 2008, a sea battle occurred between Sri Lankan navy and Sea Tigers. During the initial attack at about 05:45 seven Black Sea Tigers died, while four LTTE attack craft were destroyed, 14 Tamil Tigers were killed and about as many others were reported injured. The Sea Tigers then intercepted a twenty-vessel strong Sri Lankan Navy flotilla escorting a

The battle followed reports that the Sri Lanka's air force had claimed to have bombed a base of the Sea Tiger chief, Soosai and captured a Sea Tiger base at Nachchikuda, along the north-western seaboard. The Sri Lanka Army launched heavy artillery barrages across the Northern Front following the sea battle. The attack also followed a dual Air Tiger air attack.


Demise

After 2005 the Sri Lankan Navy had undergone several major reforms and unlike in the past the navy received more political support. Thus with the beginning of the Fourth Eelam War the Sea Tigers faced a more organised enemy adapted to asymmetric warfare. Development of the navy's intelligence wing and centralizing intelligence agencies allowed the government to track LTTE smuggling ships and instead of attempting stop convoys bringing weapons ashore the navy attacked smuggling ships. Initially stopping at 200 nautical miles to unload cargo to smaller boats, the LTTE was forced to carry out operations further away due to loss of ships and in 2007 SLN followed and sank them near Australian territory. During naval engagements the Sea tigers who relied on swarming and suicide boats found themselves outnumbered due to the introduction of the Arrow-class which was of higher quality. When the LTTE used the standard tactic of swarming larger patrol vessels the SLN would fall back while the confused Sea Tiger units are swarmed by arrow boats and outnumbered 10 to 40. The use of sonars alongside simpler methods such as booms alongside increased patrols around ports countered frogmen actions. The Sea Tiger force was annihilated during April 2009 attack by Sri Lanka Army and on May 18, 2009 the Sri Lankan government confirmed that Colonel Soosai was killed when a rocket hit the armored-plated van he was travelling in. As a result of the military offensive that ended in May 2009, in the North of the country the Sri Lanka Armed Forces first recaptured all of the western seaboard that was once controlled by the LTTE, thus depriving the Sea Tigers the bases it had in the west. On the eastern seaboard the LTTE has also lost all of its Sea tigers bases and coast line it controlled including the headquarters of the Sea Tigers in the town of Mullaitivu. Although the Sea Tigers were initially able to put up stout resistance as several major sea engagements have occurred in the early months of 2009 with the Sea tigers trying to penetrate the

Units


Boats

Boats used by the LTTE are divided into Gunboats, Explosive Boats and Low Profile Vessels. Boats designs ranged from those based on leisure to fishing craft. These boats could be up to 15 meters long, and were usually equipped with four to six 250 Hp

s. While inferior to the patrol craft of the Sri Lankan Navy, the use of swarm tactics together with suicide boats negated the disadvantage. The LTTE were also said to possess radar evading stealth boats which are believed to be from North Korea. While their radar evading capabilities have been questioned their low profile makes them harder to spot. Light fibreglass boats were used for suicide bomber attacks. For every 20 Gunboats in a swarm there were 3 or 4 suicide craft which attempt to destroy or at least immobilize the larger vessels while gunboats distract them. The LTTE also manufactured several Low Profile Vessels which are slower than other boats but stealthier. The Sea Tiger attack vessels are only at sea during operations and training; when idle they are loaded on large trailers and hidden in the dense jungle southwest of Mullaitivu or even transported to the west coast if needed.


Ships

equipment from neighboring countries. As there were no large ports under LTTE control, the supplies were loaded onto smaller vessels that could land directly on the beaches. From March 2003 to October 2007, the Sri Lankan Navy destroyed ten of these vessels in the Indian Ocean, crippling the LTTE's supply line.


Submersibles

The LTTE built several crudely built submersibles and semi-submersibles based on

Personnel

The total personnel strength was between 2,000-3,000 women and men. Women operated the boats on an equal footing as their male compatriots. However the number of personnel may vary depending on operational needs. Local arms caches were hidden in the jungle close to villages.


Analysts' views of Sea Tigers

Jane's International Defence Review, in a report on Sri Lanka, published a few years ago, pointed out that the Sea Tigers "have taken on the Sri Lankan navy with unprecedented success." A recent publication of the Woodrow Wilson School of Public and International Affairs for the Centre for Strategic and International Studies reckons that they have destroyed 30 per cent of Sri Lanka's navy fiberglass small craft fleet. The Sea Tigers not relying on communications with their command on shore during ongoing operations, was one factor in their success. The Sri Lankan Navy on the other hand was required to act in accordance with commanders onshore. Sea Tiger intelligence also played a key role in their operations, allowing for detailed and bold operations to be carried out in almost silent mode (highest

). The basis of Sea Tiger offensive operations could be described as sea control and keeping the SLN on their toes with their extensive sea denial tactics in the northern waters of Sri Lanka. Some analysts say the Sea Tigers have adopted the military theory of 'Versatile Maritime Force'. Sea Tiger operations could also be seen as a clear example of asymmetric warfare.


Strategic implications


India

India regarded the Sea Tigers as a "nuisance" in South Asian waters and the Indian Armed Forces and Tamil Nadu's state government had increased naval surveillance in the region. Though no clashes were reported between the Sea Tigers and Indian civil or military ships, Indian experts have suggested the government to "neutralize" it as the ongoing battle between the Tigers and Sri Lankan Navy has affected Indian fishing areas and

Sri Lanka

The LTTE once controlled parts of the northern coastline of Sri Lanka, the Sri Lankan forces stationed in the Jaffna peninsula were mainly supplied through naval convoys from Trincomalee in the east. The Sea Tigers bases were well located for attacks on these shipments, and forces the SLN to keep a significant force of fast attack patrol-boats on alert. Sea Tigers have also captured and seized the cargo of at least two Sri Lankan freighters. In many ways the Sea Tigers had adapted and challenged a larger and more modern Navy, due to their tactics being based on the understanding of SLN operations cycles, doctrine and reaction time.


Sea piracy

The Sea Tigers have been accused of hijacking 4 Sri Lankan supply vessels in the waters of Sri Lanka namely ''Irish Mona'' (in August 1995), ''Misen'' (in July 1997) ''Morong Bong'' (in July 1997) and ''Princess Kash'' (in August 1998) but it destroyed by Sri Lankan Navy's Airforce along with cargo in it. They have also dismantled equipment from a drifted vessel named ''MV Farah III'' (in December 2006). In the year 1996, Lawrence Thilakar, a member of the LTTE central committee, said that the Tigers would target both Sri Lankan military inside and outside supply lines. A second development was the LTTE's declaration on 15 July 1997, that all merchant vessels taking supplies northward to Jaffna peninsula would be considered legitimate military targets. This was aimed to cutoff the Sri Lanka's supply line to Jaffna as result of the Sri Lankans' ability to supply themselves by air was drastically reduced due to continues shot down of SLAF's supply planes. The LTTE accused Sri Lanka of
'' "shipping war materials to Jaffna under the pretext of supplying food and necessities for the people" ''.
On 28 August 1995, Tigers intercepted and taken control of the passenger ferry ''Irish Mona'' near the coastal city of Mullaitivu. The ferry was run by the government of Sri Lanka with the help of a paramilitary group known as EPDP, transporting people from the Jaffna islands to the mainland. The ship's passengers were brought to the coast safely by the Sea Tigers. When the SLN sent its two Dvora boats to investigate the incident both were sunk. The rebels lured the first boat in range of the firing line by posing as passengers waving for help on the ferry's deck, and fired with tank which was hidden in the ground, according to Colombo officials. It was then came to light that the ship was turned into a deadly trap, aimed at the Sri Lankan Navy gunboats. A short time later, the passengers (Tamils) and the ferry and its crew (Sinhalese) were released, although two of them were detained and released later on 25 October 1998. On 1 July 1997, Sea Tigers captured another Sri Lankan supply ship named '' MV Misen'' off the north-western coast of Pesalai. The Tigers' claimed that the ship was transporting Sri Lankan troops to the Jaffna peninsula. After taking the crew of 39 members off the ship, the Sri Lankan government claims the Tigers burned it down. On 14 July 1997, 7 of the crew was released and handed over to ICRC. One of the released person said that their treatment by the LTTE was good while they were in their custody, according to Amnesty International. Later on some of them were exchanged for five members who were captured by Sinhala villagers in Trincomalee, according to Amnesty International. The last 7 crew members (Sinhalese) were released on 25 October 1998 and handed over to ICRC. On 8 July 1997, a Sri Lankan supply ship named ''Morong Bong'' was detained by Tamil Tigers off the Jaffna peninsula and had taken it to Alampil in Mullaitivu with the Sea Tigers escorts where it was anchored. According to the Tigers, one of the 38 crewmen on the ship was killed when the ship took off for open waters after the Tigers demanded it stop. Later, the crew of 37 were detained. On 13 July 1997, the entire crew was released. According to reports, the captain of the ship sympathized with the rebels and called the Sri Lankan government 'merciless'. On 14 August 1998, LTTE hijacked Sri Lankan supply ship ''MV Princess Kash'' loaded with 60tons of cargo (worth of 500 million rupees) at the Mullaitivu sea and escorted towards the coast of Mullaitivu by the Sea Tigers gunboats. The 17 member Indian crew was captured and taken to the coast by the Sea Tigers. Later, the ship was bombed at 4:15pm by Sri Lankan Airforce Kfir bombers. Prior to the ship's bombing, the captain, V. N. Capro, told the Sri Lankan Navy the LTTE was investigating them and that settlement could be reached through negotiation. The VoT further reported the captain had requested the SLN not to take any military action until then, but the vessel was bombed regardless of his request. But the SLN said that they acted to prevent the delivery of ''"dangerous merchandise"'' to the Tigers, after their doubts were strengthened after the captain of the ship was alleged to be ''"acting in connivance with the LTTE"''. The crew were later handed over to ICRC on 16 August. Around 600 Jaffna traders, protested against the bombing of the ship. They accused the government as they are starving the Tamil people in Jaffna and reducing the supplies. They also demanded the Sri Lankan government to provide compensation for the cargo which was destroyed by the Sri Lankan Airforce On 23 December 2006, the crew of 25 members of a Jordanian ship which was carrying 14,000 tons of rice from India to South Africa, ''

On 23 decem., the Sea Tiger officials said that the captain of the Ship is trying to bring the ship to operation before getting aground. The ship then agrounded on the same day. On 24 December, when the captain of the crew was contacted by TamilNet and when asked whether the Sri Lanka Navy and the Sea Tigers have engaged in a military standoff, the ship captain told that,
"this, I guess is all political. We are all safe and we have good cooperation here. We were offered a good place to sleep."
They were handed over to ICRC on 25 December at 10 am. On 26th December, an Indian newspaper,

, accused the Tamil Tigers of forcing the crew to abandon the vessel and risking their lives. According to it, the skipper of the vessel said;
"First they tried to set up a bomb and explode the anchor cable and when it failed they ordered us to weigh anchor. Then, they opened fire four times to scare my crew and force us into smaller boats. We were travelling at high speed. When the boat hit waves we were tossed about. I injured my back."
He also alleged that the Tigers dismantled and removed all radio communication equipment and radar from the vessel. On May 1, 2007 Sayed Sulaiman, the chairman of the ship's owners, Salam International Trading Company gave an interview to the BBC Tamil service, saying,
"We hear from the parties who are concerned with the ship, the insurance company etc., that ... everything that could be taken – like the rice, lights, generators – has been taken from the ship. The ship is now bare."
The ''MV Sik Yang'', a 2,818-ton Malaysian-flag cargo ship which sailed from Tuticorin, India on May 25, 1999 was reported missing in waters near Sri Lanka. The ship with a cargo of bagged salt was due at the Malaysian port of

on May 31. The fate of the ship's crew of 15 is unknown. A report published on June 30, 1999 states that the vessel "may have been" captured by the LTTE as it went missing in the waters of Sri Lanka, according to 'Anti-Shipping Activity Messages'. While some of these missions have been purely opportunist in nature, most have, in some manner, been executed to support the group's on-ground war effort. In relation to more concerted maritime combat, however, piracy has not featured prominently in the LTTE's operational activities, and should be considered an adjunct rather than an integral feature of its overall tactical agenda.
