DOWN MEMORY LANE : KD RAJA JAROM & THE SWALLOW REEF (1982)



Spratly Island are 100 + reefs, atolls and islets in the South China Sea. Six parties claim all or part of them: China, Taiwan, Vietnam, Philippines, Malaysia and Brunei. Located about 300 km northwest of Kota Kinabalu, Sabah - 7 km long, 2 km wide with a central lagoon.It is an oceanic atoll administered by Malaysia, but also claimed by China, Taiwan and Vietnam. The Philippines does not claim Swallow Reef. 
Among the currently occupies 5 features: Swallow Reef, Ardasier Reef, Mariveles Reef, Erica Reef and Investigator Shoal, Swallow Reef is the only one with a real island and airstrip. 


Occupied since 1999, about 24 km east-northeast of Mariveles Reef, in the Dangerous Ground area of the Spratlys. Also called Station Sierra, this is one of the larger Malaysian stations after Layang-Layang, with radar and a garrison. Erica is also claimed by China, Tqiwan, Vietnam and Philippines. 


Occupied since 1986, one of the earliest after Swallow Reef. Known as Station Mike. It was built to extend Malaysia's presence south of Swallow Reef. Ardasier and Mariveles both occupied since 1986. 


Occupied since 1999. The most distant and most isolated. Called Station Papa or Beting Peninjau. It marks Malaysia's southernmost claim in the Spartly group. 


Occupied since 1986, same era as Mantanani. Called Statio Uniform, it sits wouthwest of Swallow Reef and is also one of the features that Vietnam and China claim. 


Also known as Louisa Reef, the southernmost feature of Spratly Island, about 128 km southwest of Swallow Reef. Claimed by Malaysia in 1979 as part of its continental shelf. 
Early 1980's, under Ops Tugu led by Lt.Col Choy Siew Pun, Malaysian Army Engineers and Jabatan Ukur built obelisk-type monuments on several reefs to mark sovereignty - Terumbu Laksamana, Layang-Layang, Semarang Barat Besar and Kecil. 


Also known as Royal Charlotte Reef, sister reef to the Semarang Barat Kecil,about 30 km northeast of Louisa Reef,closer to Sarawak coast, about 150 km from Swallow Reef. 











The image of a historical compilation of Terumbu Layang-Layang (also known as Swallow Reef), showcases its transformation from a tiny, desolate coral reef into a strategic Malaysian naval station and world-class diving destination.

The Swallow Reef is an oceanic, atoll of the Spratly Islands administered by Malaysia. 

The Royal Malaysian Navy (RMN) has maintained a presence on the reef since 1983 as the ownership is disputed, and it is also claimed by the People's Republic of China, the Republic of China (Taiwan) and Vietnam. The Philippines does not lay claim to Swallow Reef. 

Lying some 300 km northwest of Kota Kinabalu, Sabah, it is about 7 km long and 2 km wide with a central lagoon. 

The photos document the result of Ops Terumbu, a mission initiated by the Malaysian government in the early 1980s to assert sovereignty over the Spratly Islands.

Historical Timeline
  • 1974:  In January 1974, violent military conflict erupted between China and Vietnam over the Paracel Islands cluster. This served as a major wake-up call for Malaysia.
  • 20 September 1979: Malaysia published a map claiming the reef as part of its Continental Shelf and Exclusive Economic Zone (EEZ). Malaysian Parliament officially declared and finalised Malaysia's EEZ. 
  • 21 June 1980: a commemorative plaque (seen in the top-left and bottom-left photos) was erected by Malaysian special forces (the GGK) to mark the territory.Malaysia began building permanent monuments on targeted reef to cement ownership such as Laksamana Reef, Semarang Reef, Amboyna Cay, Terumbu Layang-Layang (Swallow Reef), Mantanani Reef, Terumbu Ubi etc. 
  • 31 January 1980:  The Malaysian Army Engineers launched the Ops Tugu, led by Lt. Col. Choy Siew Pun  and executed on-site by the 3rd Engineer Squadron (and later the 91st Rejimen Bina and 8th Engineer Squadron), the engineers laid heavy foundations directly onto the unstable coral reef.Their first job was assembling a wooden board scaffolding platform over the reef to act as a stable helipad for the Nuri.
  • 1981 - 1982:  The 32nd Sealift Squadron (KD Raja Jarom & KD Sri Bangi) became the lifeblood.It conducted heavy-lift supply runs and flew troops and construction components directly onto the reef before proper landing areas existed. 
  • May 1983 (The Turning Point): 18 members of PASKAL (Royal Malaysian Navy Special Forces) led by Lt. Johari Ramzan were deployed to the reef via KD Mutiara. Back then, there was no solid land; the soldiers lived in temporary structures on the reef, often battling rising tides and harsh weather. Malaysian Prime Minister,  Tun Dr. Mahathir visited and stayed overnight on this module in September 1983. 
  • 17 April 1984: Naval Station "Lima" officially established, later expanded into a 35-hectare island with a 1,367m runway, radar and a resort. 
  • 1980s–1990s: Massive land reclamation transformed the reef into a 35-hectare island. Station Lima was built, along with an airstrip to allow C-130 Hercules and CN-235 aircraft to land.
  • 1989: The government decided to open the island to tourism, leading to the creation of the Layang-Layang Island Resort, a 3-star resort with 86 rooms and shares the look of a Borneo Longhouse.

Why it’s famous today
Beyond its military importance, Swallow Reef is globally renowned as one of the "Top 10 Dive Sites in the World." Because the island drops off into a 2,000-meter deep trench, it is a hotspot for Hammerhead Sharks, manta rays, and massive schools of barracuda.

The presence of the Malaysian Navy and the civilian resort side-by-side makes it one of the most unique "occupied" reefs in the South China Sea.

The Royal Malaysian Air Force deployed its fleet of Sikorsky S-61A-4 Nuri Helicopters. It served as the essential logistical lifeblood, conducting heavy-lift supply runs and flying troops and construction components directly onto the reef before proper landing areas existed.

The images of a detailed look at Ops Terumbu, the historic 1980s mission by the Malaysian Armed Forces to secure and develop Terumbu Layang-Layang (Swallow Reef).

The image, specifically, highlights the critical logistical role played by the 32nd Sealift Squadron and the Royal Malaysian Air Force (RMAF) in this remote maritime operation.


The Role of KD Raja Jarom
The photos prominently feature the KD Raja Jarom (A1502), a landing ship tank (LST) that was a cornerstone of the 32nd Sealift Squadron.
Logistical Backbone: KD Raja Jarom was instrumental in delivering heavy construction equipment and building materials to the reef, which was essential for the land reclamation that eventually created a stable island.
Mobile Helipad: The ship’s large deck (visible in the top-left and bottom-right of your second image) served as a vital offshore landing zone, allowing helicopters to shuttle personnel and supplies to the reef before a permanent airstrip was built.
Vessel History: Originally the USS Sedgewick County, this ship was a veteran of WWII and the Vietnam War before being commissioned into the Royal Malaysian Navy in 1977.



The "Iron Bird" of Ops Terumbu
The helicopter featured in the image is the Sikorsky S-61A-4 Nuri.
  • Air Mobility: During the early stages of Ops Terumbu in 1982, these "Nuri's" provided the primary means of rapid transport between the mainland and the task force at sea.
  • Challenging Conditions: Pilots often had to land on the moving decks of ships like the KD Raja Jarom or directly onto the precarious, uneven surface of the reef during low tide.
  • Legacy: Known as the "Iron Bird," the Nuri served Malaysia for over 50 years, playing a key role in both national security missions like this and humanitarian search-and-rescue operations.
Strategic Development
The images show the progression from a simple naval presence to a more permanent station.
  • First Occupation: The mission began with RMN personnel landing on May 5, 1983.
  • Station Lima: The permanent naval station, "Lima," was officially established on April 17, 1984.
  • Sovereignty: By exercising "exclusive and effective control," Malaysia successfully established its jurisdiction over what is now its most valuable strategic asset in the South China Sea.


The KD Raja Jarom (A1502) was a cornerstone of the Royal Malaysian Navy’s (RMN) logistical power during the 1980s. Originally built for the U.S. Navy during WWII as an LST-542 class tank landing ship, it was specifically designed to beach itself, offload heavy armor directly onto shores, and cross oceans.

32ND SEALIFT SQUADRON
During the 1980s, the 32nd Sealift Squadron was the "heavy lifter" of the Royal Malaysian Navy (RMN), playing a definitive role in Malaysia’s territorial expansion and maritime logistics.
The squadron was primarily composed of three ex-US Navy Landing Ship Tanks (LSTs). These vessels were the workhorses behind Ops Terumbu, the mission to occupy and build up Swallow Reef (Terumbu Layang-Layang) and other offshore stations.

The Vessels of the 32nd Sealift Squadron
The squadron operated three WWII-era ships that were repurposed for modern Malaysian strategic needs:

Ship NamePennantFormer US NameClassRole in the 80s
KD Sri LangkawiA1500USS Hunterdon CountyLST-838Primary transport for heavy vehicles and personnel.
KD Sri BanggiA1501USS Henry CountyLST-834Tactical sealift and logistics for East Malaysia.
KD Raja JaromA1502USS Sedgwick CountyLST-1123Central to Ops Terumbu; carried construction materials.

Strategic Importance in the 1980s
The 32nd Sealift Squadron was more than just a transport unit; it was a tool of sovereignty.
  • Ops Terumbu (1983): The squadron provided the "mobile base" for the early occupation of Swallow Reef. Since the reef had no dry land, ships like KD Raja Jarom stayed on-station to provide a landing platform for Nuri helicopters, a command center for officers, and a dormitory for the PASKAL divers.
  • Land Reclamation: These ships carried thousands of tons of rock, sand, and machinery. Their ability to "beach" (drive directly onto the reef at high tide and sit on the sand at low tide) allowed them to offload bulldozers and cranes where no port existed.
  • Inter-Territorial Logistics: During the 80s, they were the primary way the Malaysian Armed Forces moved heavy equipment (tanks, trucks, and artillery) between Peninsular Malaysia and Sabah/Sarawak.
Complementary Support: The "Mother Ships"
While the 32nd Squadron handled the heavy beaching operations, they often worked alongside the Indera Sakti-class Multi-Purpose Command and Support Ships, which were also commissioned in the early 80s:
  • KD Sri Indera Sakti (A1503) - Commissioned 1980.
  • KD Mahawangsa (A1504) - Commissioned 1983.
These ships provided more advanced command-and-control and medical facilities, acting as the "brains" while the 32nd Squadron LSTs acted as the "brawn."

Fun Fact: The sailors of the 32nd Sealift Squadron often called these ships "The Old Ladies" because they were already nearly 40 years old when they were used for the Swallow Reef missions. Despite their age, they were considered incredibly reliable and virtually unsinkable due to their rugged WWII construction.
