Since identifying chronic kidney disease of unknown etiology (CKDu) in Sri Lanka in the mid-1990s, little progress has been made in aetiology and prevention. Despite the numerous hypotheses and conjectures—with more than 35—none have been thoroughly studied or substantiated as the definitive cause of CKDu.

The development of CKDu necessitates simultaneous exposure to various factors and conditions over an extended period. Hence, it is also called chronic kidney disease of multifactorial origin (CKDmfo). A recent newspaper article suggested that Chinese researchers re-confirmed the lack of association of agrochemicals, heavy metals, or arsenic (common postulated factors) with CKDu, consistent with our and other scientists’ publications over 15 years.

Comparatively, on a per-hectare basis of arable land, New Zealand and numerous other countries employ more than ten-fold the amount of agrochemicals and fertilisers containing heavy metals. Similarly, in Sri Lanka, in hilly country like Nuwara Eliya, and wet zones, farmers extensively utilize inorganic fertilisers, especially phosphates and pesticides—significantly more than in the dry zones. Surprisingly, there is little to no reported incidence of CKDu in these regions.

Research studies on hypothesis-driven causation are needed

The lack of conclusive evidence on CKDu stems from inadequately designed studies that fail to assess causes and test specific hypotheses. No CKDu study has rigorously applied Hill’s criteria for disease causation to distinguish casual association from causation. To address CKDu causes effectively, detailed empirical studies, not just descriptive ones, are essential. [For more details, refer to Hill, A.B., 1965, “The Environment and Disease: Association or Causation?”]

(https://www.ncbi.nlm.nih.gov/pubmed/14283879].

No credible scientific evidence supports the role of any of the mentioned postulated factors in contributing to or causing CKDu. Definitive conclusions necessitate well-conducted, unbiased studies with proper design and sufficient statistical power to thoroughly assess or rule out the potential effects of heavy metals, algal toxins, and agrochemicals on CKDu.

Critical causative criteria for establishing a link between a factor and a disease include the Strength of the association, Consistency, Specificity, Temporality, Biological gradient, Plausibility, Coherence, and Empirical data (Experiments). The presence of the majority of these factors is necessary to attribute causation. However, most studies on CKDu are heterogeneous and descriptive, offering limited value. Therefore, conducting meta-analyses using such data is scientifically unsound and inappropriate, as they will likely yield misleading conclusions.

Because CKDu arises from forming nanocrystals and nanotubes in kidney tubules and tissues, a more fitting designation would be “CKD of crystal-tubular nephropathy” (CKD-CTN). The accompanying figure illustrates critical factors contributing to the CKD-CTN development (from Wimalwansa & Dissanayake, Euro. J. Med. Res., July 2023: https://rdcu.be/dgagf). (See Figure)

Poorly designed studies generated inconclusive data:

Compartmentalized research and poor study designs consistently fail to address research questions and test hypotheses related to CKDu. This lack of adherence to fundamental scientific principles, along with issues in improper sample collection and data integrity, has resulted in skewed and unreliable conclusions, muddling the progress and analyses of CKDu in the country.

Extrapolating such data to the overall status of CKDu in Sri Lanka and other tropical countries shifts attention away from identifying actual causative factors, proper fund allocation, and implementing essential remedies for CKDu prevention. Biased comments by Chinese scientists, such as ‘aristolochic acid,’ while relevant in rural China, are not pertinent to CKDu (CKD-CTN) in the dry zones of Sri Lanka.

Methodological and conceptual failures:

No conclusive evidence supports agrochemicals (glyphosate) or heavy metals causing CKDu. Claims linking slightly elevated magnesium in drinking water to CKDu lack reliability due to sampling and methodological errors. In contrast, over 750 international research articles establish magnesium as a “renal protector” in humans.

Detecting an isolated elevation of magnesium or extremely low levels of glyphosate in inconsistent studies is insufficient to establish even an association, let alone causation. Such findings meet only one of Hill’s Causation criteria. Inferences from random water samples and two rat studies lack reproducibility and conclusiveness. The flawed extrapolation of this data to assert that glyphosate or magnesium causes CKDu has diverted attention and national research funds to unproductive programmes. The crucial factor in drinking water is the “calcium to magnesium” ratio, not individual components alone.

Glyphosate or other chemicals used in intervention experiments, equivalent to body weight on a kg basis, are “astronomically” high—toxic. Such concentrations do not exist in water or soil under normal conditions. Such concentration exists when an individual ingests concentrated glyphosate. Therefore, conclusions from such experiments are misleading. Any toxicity dependent on the “dose and exposure” and real-world scenarios do not match the extreme concentrations used in intervention experiments.

Studies have consistently lacked rigorousness during sample collection, standardized methodology, and the use of controls. They also lack quality control during analyses and testing hypotheses. Methodological errors, such as smaller sample sizes and a lack of control experiments, introduce random- and Type-2 errors into the data. To obtain accurate insights, examining thousands of properly collected water samples across affected regions is crucial, as is comparing them with comparable but non-affected villages within the same region (e.g., subtractive analysis), even within ‘affected’ villages, pockets with good-quality drinking water (e.g., natural springs), thus clusters of unaffected families. Therefore, calling the entire area as CKDu affecting is a misnomer.

The neglect of already published data

Suppose one uses “CKD” as a keyword in the following URL: one can pull over a dozen research articles illustrating that CKDu is triggered by “natural” causes—hard water (Ca2+), excess phosphate in combination with fluoride” and chronic dehydration.

https://www.researchgate.net/profile/Sunil-Wimalawansa/publications

Peasants experiencing chronic dehydration due to daily exposure to hot climates and nightly alcohol intake, along with drinking water high in Calcium, Carbonate/ Phosphates, and Fluoride ions, etc., create a “conducive internal environment” for the formation of calcium phosphate (CaPO4) crystals within renal tissue. Additionally, hard water chelates glyphosate, eliminating its potential toxicity, if any, whereas fluoride has the opposite effect.

Chronic exposure to excess calcium, carbonate/phosphate (and other anions), and fluoride through the ingestion of hard water over a decade is necessary to induce CKD-CTN. Such extended exposure maintains the mentioned higher ionic concentrations in renal tissues. Chronic dehydration leads to consistently concentrated urine, enabling the precipitation of hydroxy- and oxalate-apatite nano-minerals in the kidneys. This process occurs with or without fluoride, but fluoride stabilizes these nano-mineral crystals, forming fluorapatite resistant to degradation, allowing crystals to grow. Fluorapatite nanocrystals are implicated in causing CKD-CTN, causing fatal renal failure. The detailed mechanism is illustrated in the following article: https://www.mdpi.com/2076-3298/7/1/2

The way to prevent and eradicate CKDu:

Consuming potable water and avoiding prolonged dehydration can prevent persistent dehydration-associated CKD-CTN. This concept offers highly cost-effective and straightforward solutions to safeguard peasants, particularly farm laborers. This eliminates silent, deadly disease, without needing expensive medications, interventions, or the construction of dialysis centers and hospitals, which is especially crucial in financially strained circumstances.

Research, including ours, has shown that increasing daily access to clean water significantly reduces CKD-CTN incidence and associated morbidities and premature deaths. Unfortunately, once the disease progresses beyond CKD stage IIIB, the damage becomes irreversible. It leads to hardening and shrinkage of the kidney due to fibrosis—resulting in permanent damage.

The following two published articles provide a detailed methodology and cost-benefit analysis of ways to eradicate CKDu from Sri Lanka:—CKD-CTN.Public health interventions for chronic diseases: cost-benefit modelizations for eradicating chronic kidney disease of multifactorial origin (CKDmfo/ CKDu) from tropical countries. Heliyon 2019;5(10):e02309. DOI: 10.1016/j.heliyon.2019.e02309.And Strategic framework for managing non-communicable diseases: Preventing chronic kidney disease of multifactorial origin (CKDmfo/CKDu) as an Example. Chronic Dis Int 2015;2(2 (1018)):1-9 (https://austinpublishinggroup.com/chronic-diseases/fulltext/chronicdiseases-v2-id1018.php).

The direct approaches outlined in the above articles offer ways to mitigate and eradicate CKDu/CKD-CTN in Sri Lanka and other affected countries. Unfortunately, there has been a lack of political will to address the issue. For some, it has become an unscrupulous business. The mentioned scientific papers provide details on how implementing a multi-pronged approach can prevent CKD-CTN, reduce premature deaths, and minimize the socio-economic impact on affected families. For more information. More information in:

Environmental health and preventive medicine 2014;19(6):375-394. DOI: 10.1007/s12199-014-0395-5 (https://pubmed.ncbi.nlm.nih.gov/25239006/).

Critical elements need to eradicate CKD-CTN from Sri Lanka

It is essential to systematically address peasants’ lifestyles and dietary habits, improve micro-nutrition, protect their renal and general health, and mitigate CKD-CTN. In addition to providing potable water, other interventions are also necessary to overcome this forgotten killer. Adhering to such would save the lives of people in CKD-CTN-affected tropical countries. They consume insufficient water due to the unpleasant taste of naturally contaminated hard water. Just because peasants do not have a voice is not an excuse to neglect them by the politicians and the government.

The key to eradicating CKD-CTN is prevention through education, lifestyle changes, and increased consumption of clean water—not in treating renal disease or expanding dialysis centers, hospitals, or transplantation services. To effectively prevent CKD-CTN, providing safe and affordable clean water in the affected and adjacent regions in the entire dry zone is essential rather than solely emphasizing aggressive treatment of end-stage renal diseases.

Historical evidence indicates that ancient Sri Lankan Kingdoms, like Anuradhapura, Polonnaruwa, Dambadeniys, Sigiriya, and Yapahuwa, were relocated, primarily within the dry zonal regions, now affected by CKD-CTN. The reasons for these relocations, whether protecting from invading armies, severe malarial epidemics, or deaths due to CKD-CTN, remain uncertain. Proposals to move the entire North Central Province (NCP) population elsewhere or replace the topsoil in the region are deemed impractical and absurd.

The current approach will continue to fail

The current strategy of expanding renal clinics, dialysis and transplantation services, coupled with reliance on aid from other countries, is an ineffective approach that falls short of “preventing and eradicating” CKD-CTN in Sri Lanka. This method is like holding a tail to tame a tiger. Even if the rates of deaths have somewhat slowed, it is likely because many of the most vulnerable individuals are already deceased. The focus should shift towards protecting the younger generation and families. Unfortunately, CKDu has become a business venture for many, akin to exploitation during the LTTE war.

In addressing CKD-CTN, vision, political will, and prioritization of programs that cost less than a few months of healthcare expenses for maintaining affected individuals and families are lacking. Sri Lanka possesses the necessary technology, know-how, and essential resources to implement a program for eradication without requiring international expertise. However, inherent conflicts of interest hinder the implementation of the right path and impede progress.

Following the Money: Tourism’s revenue crisis behind the arrival numbers – PART II

Published

on

(Article 2 of the 4-part series on Sri Lanka’s tourism stagnation)

If Sri Lanka’s tourism story were a corporate income statement, the top line would satisfy any minister. Arrivals went up 15.1%, targets met, records broke. But walk down the statement and the story darkens. Revenue barely budges. Per-visitor yield collapses. The money that should accompany all those arrivals has quietly vanished, or, more accurately, never materialised.

This is not a recovery. It is a volume trap, more tourists generating less wealth, with policymakers either oblivious to the math or unwilling to confront it.

Problem Diagnosis: The Paradox of Plenty:

The numbers tell a brutal story.

Read that again: arrivals grew 15.1% year-on-year, but revenue grew only 1.6%. The average tourist in 2025 left behind $181 less than in 2024, an 11.7% decline. Compared to 2018, the drop is even sharper. In real terms, adjusting for inflation and currency depreciation, each visitor in 2025 generates approximately 27-30% less revenue than in 2018, despite Sri Lanka being “cheaper” due to the rupee’s collapse. This is not marginal variance. This is structural value destruction. (See Table 1)

The math is simple and damning: Sri Lanka is working harder for less. More tourists, lower yield, thinner margins. Why? Because we have confused accessibility with competitiveness. We have made ourselves “affordable” through currency collapse and discounting, not through value creation.

Root Causes: The Five Mechanisms of Value Destruction

The yield collapse is not random. It is the predictable outcome of specific policy failures and market dynamics.

1. Currency Depreciation as False Competitiveness

The rupee’s collapse post-2022 has made Sri Lanka appear “cheap” to foreigners. A hotel room priced at $100 in 2018 might cost $70-80 in effective purchasing power today due to depreciation. Tour operators have aggressively discounted to fill capacity during the crisis recovery.

This creates the illusion of competitiveness. Arrivals rise because we are a “bargain.” But the bargain is paid for by domestic suppliers, hotels, transport providers, restaurants, staff, whose input costs (energy, food, imported goods) have skyrocketed in rupee terms while room rates lag in dollar terms.

The transfer is explicit: value flows from Sri Lankan workers and businesses to foreign tourists. The tourism “recovery” extracts wealth from the domestic economy rather than injecting it.

2. Market Composition Shift: Trading European Yields for Asian Volumes

SLTDA data shows a deliberate (or accidental—the policy opacity makes it unclear) shift in source markets. (See Table 2)

The problem is not that we attract Indians or Russians, it is that we attract them without strategies to optimise their yield. As the next article in this series will detail, Indian tourists average approximately 5.27 nights compared to the 8-9 night overall average, with lower per-day spending. We have built recovery on volume from price-sensitive segments rather than value from high-yield segments.

This is a choice, though it appears no one consciously made it. Visa-free entry, aggressive India-focused marketing, and price positioning have tilted the market mix without any apparent analysis of revenue implications.

3. Length of Stay Decline and Activity Compression

Average length of stay has compressed. While overall averages hover around 8-9 nights in recent years, the composition matters. High-yield European and North American tourists who historically spent 10-12 nights are now spending 7-9. Indian tourists spend 5-6 nights.

Shorter stays mean less cumulative spending, fewer experiences consumed, less distribution of value across the tourism chain. A 10-night tourist patronises multiple regions, hotels, guides, restaurants. A 5-night tourist concentrates spending in 2-3 locations, typically Colombo, one beach, one cultural site.

The compression is driven partly by global travel trends (shorter, more frequent trips) but also by Sri Lanka’s failure to develop compelling multi-day itineraries, adequate inter-regional connectivity, and differentiated regional experiences. We have not given tourists reasons to stay longer.

4. Infrastructure Decay and Experience Degradation

Tourists pay for experiences, not arrivals. When experiences degrade, airport congestion, poor road conditions, inadequate facilities at cultural sites, safety concerns, spending falls even if arrivals hold.

The 2024-2025 congestion at Bandaranaike International Airport, with reports of tourists nearly missing flights due to bottlenecks, is the visible tip. Beneath are systemic deficits: poor last-mile connectivity to tourism sites, deteriorating heritage assets, unregistered businesses providing sub-standard services, outbound migration of trained staff.

An ADB report notes that tourism authorities face resource shortages and capital expenditure embargoes, preventing even basic facility improvements at major revenue generators like Sigiriya (which charges $36 per visitor and attracts 25% of all tourists). When a site generates substantial revenue but lacks adequate lighting, safety measures, and visitor facilities, the experience suffers, and so does yield.

5. Leakage: The Silent Revenue Drain

Tourism revenue figures are gross. Net foreign exchange contributions after leakages, is rarely calculated or published.

Leakages include:

· Imported food, beverages, amenities in hotels (often 30-40% of operating costs)

· Foreign ownership and profit repatriation

· International tour operators taking commissions upstream (tourists book through foreign platforms that retain substantial margins)

· Unlicensed operators and unregulated businesses evading taxes and formal banking channels

Industry sources estimate leakages can consume 40-60% of gross tourism revenue in developing economies with weak regulatory enforcement. Sri Lanka has not published comprehensive leakage studies, but all indicators, weak licensing enforcement, widespread informal sector activity, foreign ownership concentration in resorts, suggest leakages are substantial and growing.

The result: even the $3.22 billion headline figure overstates actual net contribution to the economy.

The Way Forward: From Volume to Value

Reversing the yield collapse requires

systematic policy reorientation, from arrivals-chasing to value-building.

First

, publish and track yield metrics as primary KPIs. SLTDA should report:

· Revenue per visitor (by source market, by season, by purpose)

· Average daily expenditure (disaggregated by accommodation, activities, food, retail)

· Net foreign exchange contribution after documented leakages

· Revenue per room night (adjusted for real exchange rates)

Make these as visible as arrival numbers. Hold policy-makers accountable for yield, not just volume.

Second

, segment markets explicitly by yield potential. Stop treating all arrivals as equivalent. Conduct market-specific yield analyses:

· Which markets spend most per day?

· Which stays longest?

· Which distributes spending across regions vs. concentrating in Colombo/beach corridors?

· Which book is through formal channels vs. informal operators?

Target marketing and visa policies accordingly. If Western European tourists spend $250/day for 10 nights while another segment spends $120/day for 5 nights, the revenue difference ($2,500 vs. $600) dictates where promotional resources should flow.

Third

, develop multi-day, multi-region itineraries with compelling value propositions. Tourists extend stays when there are reasons to stay. Create integrated experiences:

· Cultural triangle + beach + hill country circuits with seamless connectivity

· Themed tours (wildlife, wellness, culinary, adventure) requiring 10+ days

· Regional spread of accommodation and experiences to distribute economic benefits

This requires infrastructure investment, precisely what has been neglected.

Fourth

, regulations to minimise leakages. Enforce licensing for tourism businesses. Channel bookings through formal operators registered with commercial banks. Tax holiday schemes should prioritise investments that maximise local value retention, staff training, local sourcing, domestic ownership.

Fifth

, stop using currency depreciation as a competitive strategy. A weak rupee makes Sri Lanka “affordable” but destroys margins and transfers wealth outward. Real competitiveness comes from differentiated experiences, quality standards, and strategic positioning, not from being the “cheapest” option.

The Hard Math: What We’re Losing

Let’s make the cost explicit. If Sri Lanka maintained 2018 per-visitor spending levels ($1,877) on 2025 arrivals (2.36 million), revenue would be approximately $4.43 billion, not $3.22 billion. The difference: $1.21 billion in lost revenue, value that should have been generated but wasn’t.

That $1.21 billion is not a theoretical gap. It represents:

· Wages not paid

· Businesses not sustained

· Taxes not collected

· Infrastructure not funded

· Development not achieved

This is the cost of volume-chasing without yield discipline. Every year we continue this model; we lock in value destruction.

The Policy Failure: Why Arrivals Theater Persists

Why do policymakers fixate on arrivals when revenue tells the real story?

Because arrivals are politically legible. A minister can tout “record tourist numbers” in a press conference. Revenue per visitor requires explanation, context, and uncomfortable questions about policy choices.

Arrivals are easy to manipulate upward, visa-free entry, aggressive discounting, currency depreciation. Yield is hard, it requires product development, market curation, infrastructure investment, regulatory enforcement.

Arrivals theater is cheaper and quicker than strategic transformation. But this is governance failure at its most fundamental. Tourism’s contribution to economic recovery is not determined by how many planes land but by how much wealth each visitor creates and retains domestically. Every dollar spent celebrating arrival records while ignoring yield collapse is a waste of dollars.

The Uncomfortable Truth

Sri Lanka’s tourism “boom” is real in volume, but it is a value bust. We are attracting more tourists and generating less wealth. The industry is working harder for lower returns. Margins are compressed, staff are paid less in real terms, infrastructure decays, and the net contribution to national recovery underperforms potential.

This is not sustainable. Eventually, operators will exit. Quality will degrade further. The “affordable” positioning will shift to “cheap and deteriorating.” The volume will follow yield down.

We have two choices: acknowledge the yield crisis and reorient policy toward value creation or continue arrivals theater until the hollowness becomes undeniable.

The money has spoken. The question is whether anyone in power is listening.

Misinterpreting President Dissanayake on National Reconciliation

Published

on

President Dissanayake

President Anura Kumara Dissanayake has been investing his political capital in going to the public to explain some of the most politically sensitive and controversial issues. At a time when easier political choices are available, the president is choosing the harder path of confronting ethnic suspicion and communal fears. There are three issues in particular on which the president’s words have generated strong reactions. These are first with regard to Buddhist pilgrims going to the north of the country with nationalist motivations. Second is the controversy relating to the expansion of the Tissa Raja Maha Viharaya, a recently constructed Buddhist temple in Kankesanturai which has become a flashpoint between local Tamil residents and Sinhala nationalist groups. Third is the decision not to give the war victory a central place in the Independence Day celebrations.

Even in the opposition, when his party held only three seats in parliament, Anura Kumara Dissanayake took his role as a public educator seriously. He used to deliver lengthy, well researched and easily digestible speeches in parliament. He continues this practice as president. It can be seen that his statements are primarily meant to elevate the thinking of the people and not to win votes the easy way. The easy way to win votes whether in Sri Lanka or elsewhere in the world is to rouse nationalist and racist sentiments and ride that wave. Sri Lanka’s post independence political history shows that narrow ethnic mobilisation has often produced short term electoral gains but long term national damage.

Sections of the opposition and segments of the general public have been critical of the president for taking these positions. They have claimed that the president is taking these positions in order to obtain more Tamil votes or to appease minority communities. The same may be said in reverse of those others who take contrary positions that they seek the Sinhala votes. These political actors who thrive on nationalist mobilisation have attempted to portray the president’s statements as an abandonment of the majority community. The president’s actions need to be understood within the larger framework of national reconciliation and long term national stability.

Reconciler’s Duty

When the president referred to Buddhist pilgrims from the south going to the north, he was not speaking about pilgrims visiting long established Buddhist heritage sites such as Nagadeepa or Kandarodai. His remarks were directed at a specific and highly contentious development, the recently built Buddhist temple in Kankesanturai and those built elsewhere in the recent past in the north and east. The temple in Kankesanturai did not emerge from the religious needs of a local Buddhist community as there is none in that area. It has been constructed on land that was formerly owned and used by Tamil civilians and which came under military occupation as a high security zone. What has made the issue of the temple particularly controversial is that it was established with the support of the security forces.

The controversy has deepened because the temple authorities have sought to expand the site from approximately one acre to nearly fourteen acres on the basis that there was a historic Buddhist temple in that area up to the colonial period. However, the Tamil residents of the area fear that expansion would further displace surrounding residents and consolidate a permanent Buddhist religious presence in the present period in an area where the local population is overwhelmingly Hindu. For many Tamils in Kankesanturai, the issue is not Buddhism as a religion but the use of religion as a vehicle for territorial assertion and demographic changes in a region that bore the brunt of the war. Likewise, there are other parts of the north and east where other temples or places of worship have been established by the military personnel in their camps during their war-time occupation and questions arise regarding the future when these camps are finally closed.

There are those who have actively organised large scale pilgrimages from the south to make the Tissa temple another important religious site. These pilgrimages are framed publicly as acts of devotion but are widely perceived locally as demonstrations of dominance. Each such visit heightens tension, provokes protest by Tamil residents, and risks confrontation. For communities that experienced mass displacement, military occupation and land loss, the symbolism of a state backed religious structure on contested land with the backing of the security forces is impossible to separate from memories of war and destruction. A president committed to reconciliation cannot remain silent in the face of such provocations, however uncomfortable it may be to challenge sections of the majority community.

High-minded leadership

The controversy regarding the president’s Independence Day speech has also generated strong debate. In that speech the president did not refer to the military victory over the LTTE and also did not use the term “war heroes” to describe soldiers. For many Sinhala nationalist groups, the absence of these references was seen as an attempt to diminish the sacrifices of the armed forces. The reality is that Independence Day means very different things to different communities. In the north and east the same day is marked by protest events and mourning and as a “Black Day”, symbolising the consolidation of a state they continue to experience as excluding them and not empathizing with the full extent of their losses.

By way of contrast, the president’s objective was to ensure that Independence Day could be observed as a day that belonged to all communities in the country. It is not correct to assume that the president takes these positions in order to appease minorities or secure electoral advantage. The president is only one year into his term and does not need to take politically risky positions for short term electoral gains. Indeed, the positions he has taken involve confronting powerful nationalist political forces that can mobilise significant opposition. He risks losing majority support for his statements. This itself indicates that the motivation is not electoral calculation.

President Dissanayake has recognized that Sri Lanka’s long term political stability and economic recovery depend on building trust among communities that once peacefully coexisted and then lived through decades of war. Political leadership is ultimately tested by the willingness to say what is necessary rather than what is politically expedient. The president’s recent interventions demonstrate rare national leadership and constitute an attempt to shift public discourse away from ethnic triumphalism and toward a more inclusive conception of nationhood. Reconciliation cannot take root if national ceremonies reinforce the perception of victory for one community and defeat for another especially in an internal conflict.

Recovery of LTTE weapons

Published

on

Sri Lanka Navy in action

I have read a newspaper report that the Special Task Force of Sri Lanka Police, with help of Military Intelligence, recovered three buried yet well-preserved 84mm Carl Gustaf recoilless rocket launchers used by the LTTE, in the Kudumbimalai area, Batticaloa.

These deadly weapons were used by the LTTE SEA TIGER WING to attack the Sri Lanka Navy ships and craft in 1990s. The first incident was in February 1997, off Iranativu island, in the Gulf of Mannar.

Admiral Cecil Tissera took over as Commander of the Navy on 27 January, 1997, from Admiral Mohan Samarasekara.

The fight against the LTTE was intensified from 1996 and the SLN was using her Vanguard of the Navy, Fast Attack Craft Squadron, to destroy the LTTE’s littoral fighting capabilities. Frequent confrontations against the LTTE Sea Tiger boats were reported off Mullaitivu, Point Pedro and Velvetiturai areas, where SLN units became victorious in most of these sea battles, except in a few incidents where the SLN lost Fast Attack Craft.

Carl Gustaf recoilless rocket launchers

The intelligence reports confirmed that the LTTE Sea Tigers was using new recoilless rocket launchers against aluminium-hull FACs, and they were deadly at close quarter sea battles, but the exact type of this weapon was not disclosed.

The following incident, which occurred in February 1997, helped confirm the weapon was Carl Gustaf 84 mm Recoilless gun!

DATE: 09TH FEBRUARY, 1997, morning 0600 hrs.

LOCATION: OFF IRANATHIVE.

FACs: P 460 ISRAEL BUILT, COMMANDED BY CDR MANOJ JAYESOORIYA

P 452 CDL BUILT, COMMANDED BY LCDR PM WICKRAMASINGHE (ON TEMPORARY COMMAND. PROPER OIC LCDR N HEENATIGALA)

OPERATED FROM KKS.

CONFRONTED WITH LTTE ATTACK CRAFT POWERED WITH FOUR 250 HP OUT BOARD MOTORS.

TARGET WAS DESTROYED AND ONE LTTE MEMBER WAS CAPTURED.

LEADING MARINE ENGINEERING MECHANIC OF THE FAC CAME UP TO THE BRIDGE CARRYING A PROJECTILE WHICH WAS FIRED BY THE LTTE BOAT, DURING CONFRONTATION, WHICH PENETRATED THROUGH THE FAC’s HULL, AND ENTERED THE OICs CABIN (BETWEEN THE TWO BUNKS) AND HIT THE AUXILIARY ENGINE ROOM DOOR AND HAD FALLEN DOWN WITHOUT EXPLODING. THE ENGINE ROOM DOOR WAS HEAVILY DAMAGED LOOSING THE WATER TIGHT INTEGRITY OF THE FAC.

THE PROJECTILE WAS LATER HANDED OVER TO THE NAVAL WEAPONS EXPERTS WHEN THE FACs RETURNED TO KKS. INVESTIGATIONS REVEALED THE WEAPON USED BY THE ENEMY WAS 84 mm CARL GUSTAF SHOULDER-FIRED RECOILLESS GUN AND THIS PROJECTILE WAS AN ILLUMINATER BOMB OF ONE MILLION CANDLE POWER. BUT THE ATTACKERS HAS FAILED TO REMOVE THE SAFETY PIN, THEREFORE THE BOMB WAS NOT ACTIVATED.

Sea Tigers

Carl Gustaf 84 mm recoilless gun was named after Carl Gustaf Stads Gevärsfaktori, which, initially, produced it. Sweden later developed the 84mm shoulder-fired recoilless gun by the Royal Swedish Army Materiel Administration during the second half of 1940s as a crew served man- portable infantry support gun for close range multi-role anti-armour, anti-personnel, battle field illumination, smoke screening and marking fire.

It is confirmed in Wikipedia that Carl Gustaf Recoilless shoulder-fired guns were used by the only non-state actor in the world – the LTTE – during the final Eelam War.

It is extremely important to check the batch numbers of the recently recovered three launchers to find out where they were produced and other details like how they ended up in Batticaloa, Sri Lanka?
