Graduation ceremonies, in any context, are moments to celebrate a group’s successful completion of often rigorous tasks, physical or otherwise. For elite military units, these events generally follow the conclusion of a particularly strenuous training regimen and are a moment of great pride for those who pass the test and are often involve significant pomp and ceremony to mark the occasion. Case in point, a graduation ceremony at the bottom of a diving pool for a group of trainees who had passed the Singaporean Navy’s Combat Diver Course, with everyone in full scuba gear. Like a scene out of “Aquaman,” at one particularly triumphant point, an individual catches an actual trident, a common symbol associated with naval special operations units around the world, including the U.S. Navy SEALs, which was dropped into the tank from above.
This ceremony, seen in the video below, took place in 2018 and marked the graduation of individuals who had passed the 39th iteration of the Combat Diver Course. The dive pool, which is four meters, or around 13 feet, deep, is located at the Republic of Singapore Armed Force’s (SAF) Sembawang Camp in the northern part of the country. The pool is specifically designed so groups can see what is happening underwater, with large windows along one side, and is also used for public demonstrations of the skills of personnel assigned to the country’s elite Naval Diving Unit (NDU).
Completing this four-month-long training program is a key requirement for individuals seeking to join the NDU, which broadly analogous to other naval special operations units, such as the SEALs. Before attending this course, NDU candidates must first go through a modified version of the Singapore Armed Forces (SAF) basic training that lasts three months.
The Combat Diver Course “is divided into four phases: Physical Phase, Diving Phase, Basic Seamanship and Water Confidence,” according to an official Singapore Ministry of Defense brochure. As with the SEALs’ near-legendary Basic Underwater Demolition/SEAL Team course, or BUD/S, the Singaporean Navy’s training program for prospective NDU members includes a “hell week” that is designed to weed out individuals who are unlikely to make it through the entire course. It has been reported that up to 60 percent of those who start this training process regularly wash out.
Individuals taking part in the Combat Diver Course five specific tests, known as “vetoes,” that are must pass events. They must show their ability to:
- Swim two kilometers (~1.2 miles) in no more than 50 minutes.
- Run six kilometers (~3.7 miles) in 27 minutes or less.
- Pass a Diver Fitness Test that consists of swimming 500 meters (~546.8 yards) within 12 minutes, doing 52 pushups in no more than two minutes, doing 60 sit-ups in two minutes or less, doing nine chin-ups in two minutes, and running 2.4 kilometers (~1.5 miles) within 12 minutes, in that order. Trainees are allotted 10 minutes to rest after the swim and before the run, and two minutes of downtime between all of the other portions of this test.
- Make it through the “Sea Circuit” three times within 18 minutes. This is an obstacle course of sorts that involves swimming backstroke, climbing up a rope, walking across a balance beam, ascending up and then jumping off a five-meter (~5.4 yards) tall tower, doing another leg of backstroke, and then running for a total distance of 750 meters (~820 yards).
- Meet the requirements of the SAF’s standard Individual Physical Proficiency Test, which has more strenuous requirements for special operations forces personnel. “A 22-year-old must perform 40 sit-ups, jump over 242cm [~8 feet] in the standing broad jump, pull 12 chin-ups, complete the shuttle run in under 10.2 seconds, and finish the 2.4km [~1.5 miles] run in under nine minutes and 15 seconds,” according to The Strait Times, a Singaporean newspaper.
“It has been a tough 6 months for these trainees to transform from civilians to Naval Divers following their enlistment into Naval Diving Unit in March this year,” Lieutenant Colonel Sng Meng Wah, then the head of the NDU’s Dive School, said in a statement following the graduation of the 39th class of the Combat Diver Course in 2018. “They have learnt not just to dive with SCUBA and Closed Circuit Re-breathers, but in the process, have also grown physically stronger and mentally tougher in preparation for them to work in the harsh environment we divers work in.”
“This underwater parade signifies the start of their journey as a Naval Diver and showcases to their parents the diving abilities that each and every one of these divers have learnt over the course of their training in Dive school,” he continued. “I wish them all the best when they proceed to serve their National Service in the various operational units in NDU.”
Those who graduate from the Combat Diver Course and join the NDU go through various additional special operations and other advanced training courses. NDU personnel also routinely train with foreign special operations and other elite forces, including the U.S. Navy SEALs, U.S. Army Special Forces soldiers, and U.S. Marine Corps reconnaissance units.
The NDU traces its roots back to elements of the British Royal Navy’s Far East Fleet Clearance Diving Team (FECDT), which arrived in Singapore in 1959, at which time it was a self-governing British colony. When the FECDT personnel left in 1971, at which point Singapore had become an independent country, its own Navy created a new diving unit, which was initially focused on more traditional underwater salvage and demolitions missions.
The current NDU, however, is a multi-purpose special operations unit. As with other naval special operations units around the world, members of the NDU are training to carry out a wide variety of underwater tasks, including removing mines and other hazards. As part of these missions, Singaporean combat divers are trained to infiltrate and exfiltrate from mission areas underwater using scuba gear with rebreathers, as well as individual propulsion systems. Rebreathers recycle unused breathing gas, and generally do so at warmer temperatures than the surrounding water, allowing divers to operate beneath the waves for longer periods and incur less fatigue in doing so. They also do not release tell-tale streams of bubbles, which can tip off enemy forces.
NDU elements are also capable of carrying out other specialized maritime missions, including raiding ships at sea. The unit trains to carry out others kinds of missions on land, including long-range reconnaissance, as well as counter-terrorism and other direct-action operations.
All that being said, the NDU is focused primarily on missions in maritime and littoral domains, as is made clear by the dramatic underwater graduation ceremonies involving individuals in full SCUBA gear wielding symbolic tridents.
