Singapore at RIMPAC

1. Hearing the Australian perspective on training together with RSS Supreme, on the multi-national sail to RIMPAC.

2. RSS Supreme, sails with other navies during RIMPAC. Grateful that Australia, Brunei, Canada and NZ each enjoy a strong bilateral defence relationship with Singapore and these countries together help maintain a shared vision of the significance of the international rules-based maritime order — in particular, Australia (Exercise Wallaby), Brunei (Exercise Lancer) and NZ (Exercise Thunder Warrior) who host Singapore troops for our unilateral exercises.
  • Brunei and Singapore have a 53 year old Currency Interchangeability Agreement which makes both Brunei dollar and Singapore dollar banknotes and coins legal tender in either country and also cooperate extensively in defence, finance, trade and investment, tourism, health, aquaculture, and education.
  • Australia, NZ and Singapore have long maintained a security relationship as part of their wider ties, which were elevated to the level of a comprehensive strategic partnership (with Australia) and a closer economic partnership (with NZ). Beyond the usual components of this aspect of relations such as exchanges and exercises, these 3 countries are longstanding members of the Five Power Defense Arrangements (FPDA) — the oldest standing multilateral security agreement of its kind in the region. Our troops have journeyed far together, as burden sharing partners in operations that span East Timor, CTF-151, Afghanistan and Iraqi.

3. Taking on the role of Sea Combat Commander (SCC) of Task Group 2.1, SLTC Choo Jui Yeang and his command team embarked on RSS Supreme directed eight other ships from seven nations, in one of two task forces, in anti-surface and anti-submarine drills. SLTC Choo Jui Yeang is a Swedish trained Singaporean submariner that assumed command of Task Group 2.1, and he has particular expertise on submarine tactics (as a former CO of a submarine, prior to his present SCC appointment). RSS Supreme also successfully fired an Aster missile against an incoming high-speed aerial target during RIMPAC 2020.
4. RSS Supreme’s Commanding Officer LTC Eileen Chua said: "The RSN's mission includes protecting Singapore's sea lines of communication and contributing to regional peace and security. Joining RIMPAC allows us to do just that: we are able to demonstrate strength and exercise our capabilities as a form of deterrence, as well as foster stronger ties with like-minded navies through cooperation at sea.”

5. “The tremendous capability of the Hawaii ranges enables RIMPAC navies to conduct live fire exercises in support of joint and combined multi-domain training,” said Adm. John C. Aquilino, commander of U.S. Pacific Fleet.

RSS Invincible on sea trials & the countdown to a sunset ceremony for RSS Conqueror & RSS Chieftain begins

1. By late 2023 Singapore will operate 2 types of AIP submarines; with 2 Swedish built Archer class (with a 75 kW AIP plug) and 2 German built Invincible class (each with 2 HDW/Siemens PEM fuel cells of 120 kW) submarines, giving them a submerged endurance of over 18 days. Together with German, Israeli and indigenously-developed systems integrated into the combat suite, the 2,200 ton Type 218SG will be able to conduct patrols lasting over 40 days and have enhanced situational awareness and accelerated decision-making support systems, allowing submariners to rapidly orientate themselves, decide on the best course of action, and act.

2. Once the first 2 Invincible class enters service, Singapore can retire the last 2 Challenger class boats, which had insufficient automation. RSS Conqueror (ex-HMS Sjölejonet), launched in 28 May 1999 and RSS Chieftain (ex-HMS Sjöhunden), launched in 22 May 2001 are in urgent need of replacement by the future RSS Invincible and RSS Impeccable by 2022. Keeping in mind that these 52 year old boats entered Swedish service as the Sjöormen Class in 1968.

3. From photos, the Type 218SG appears to have features evolved from several TKMS designs including Types 212A (batch 2), 214 and Israel's batch 2 Dolphins.

(a) The 70 m long Type 218SG is approximately 2,200 tons. For comparison the 68.8 m long batch 2 AIP equipped Dolphin class is a 2,400 ton boat. The AIP equipped batch 2 Dolphins are 12 m longer and are nearly 500 tons more in displacement than the German Type 212As. Due to differences in mission sets, Israel’s batch 2 boats have a larger crew than either the Type 212A or the Type 214.​

(b) For reference, a single-dive distance record for a Type 212A Batch 1 was U32's cross-atlantic trip at 5,185 km (or 2,800 nm), in 19.3 days, that involved combat maneuvers along the way (one successful interdiction and one 36-hour evasion). The dive was part of a 31,000 km (or 17,000nm), 6-month overseas deployment of the submarine and a German sub tender.​
(c) Some have speculated that the Type 218SG is a 214 design with a long, 5 meter plug, simply because they assume that the Type 218SG’s beam is 6.3 meters; which is the same as the 214's beam (but I note the Mindef fact sheet only lists the length and displacement) — I think that this description is overly simplistic, given the amount of Singapore specified changes.​

4. Like the German Batch 2, Type 212s, I suspect that there are:

(i) two search mast systems (one for attack and another as a search optronic mast for general area search);​
(ii) a GABLER hoistable mast;​
(iii) a SATCOM mast; and​
(iv) a radio/comms mast,​

on the 4 Invincible class boats. The “attack optronic mast,” is gyro-stabilised, contains an infrared camera, a high-definition TV camera, an infrared beeper (to communicate with special forces), and a back-up camera. The second, the “search optronic mast,” can scan the full horizon in a few seconds to create a band of panoramic images simultaneously in both visible and infrared modes. The GABLER mast enables the boat to communicate without raising its mast.

Development and trails of a new submarine class will always be paired with problems and setbacks, but once the problems are solved, it will be by far the most advanced submarine class in the region.


""This is the first of three « Invincible-class » submarines under construction at Thyssenkrupp Marine Systems Shipyard (TKMS) in Kiel, Germany."
Does this mean that the fourth one will be build in Singapore, or that the fourth one is not yet under construction in Kiel?

@OPSSG correct me if I'm wrong, but seems this's more on patroling straits traffic and potential incursion from small boats ?
I see this as the RSN talking about the current 30 ton USV role (which will be true and used for deterrence against pirates) but I suspect the developmental roadmap for these 16m x 5m boats are more complex than stated in the article — when the MRCVs are built, I believe they can deploy these large USVs.
These 30 ton boats are too big to be deployed in the LMVs. In the past, these 16m x 5m boats were declared to be 26 tons. They seemed to have gained 4 tons — which I believe is not the case. They must have a potential customer on hand that wants RSN to introduce it first in this role.

More piracy, robbery cases in Malacca and Singapore Straits in 2020. The Straits of Malacca and Singapore are important to the global economy.

The ships in the incidents were the oil tanker Zeno, and bulk carriers Lefkada and Atlantic Diana.

“The ReCAAP ISC is concerned with the continued occurrence of incidents in the Singapore Strait. As the perpetrators of these incidents are not arrested, there is a possibility of further incidents in the Singapore Strait. This is the same pattern where pirates attacked ships in the eastbound lane of the Singapore Strait, in the waters surrounding Singapore, Johor, Batam and Bintan in 2019/2018. The strait saw a surge in the number of piracy and armed robbery incidents against ships, from seven in 2018 to 31 in 2019. Read more at Surge in piracy incidents in Singapore Strait a cause for concern for maritime safety in the region

Prior to the LMVs (which will in future also replace the MCMVs), the Singapore Navy’s MSTF (previously called Coastal Command) had 4x Bedok Class MCMVs and 12 Fearless class vessels in its orbat (for a total fleet of 16 vessels). Therefore it does not surprise me that the navy would want 12 ships.

Currently, ST Marine’s Vanguard series are only design studies or paper designs (and you can choose to call it a Vanguard 80, except that we don’t know the actual length of this ship class, presently).

Oman actually bought 4 vessels of the Fearless 75 base design — this can be the basis for minor improvements after taking in Omani user feedback.

From the preliminary illustration released by Dr Ng, it seems the hull form is based on the LMV (but the top is different and has anti-ship missiles).
Speaking in Parliament on 2 Mar 2020, during the Committee of Supply Debates, Defence Minister Ng Eng Hen said that 4 Fearless class patrol vessels will be refurbished and pushed into service in support of the Maritime Security Task Force. For a start, four refurbished patrol vessels will be dedicated and deployed for "greater persistence" to protect Singapore's territorial waters Dr Ng said. The RSN needs to work together with the TNI AL on counter-piracy efforts and Indonesian support is crucial as the eastbound lane of the Singapore Strait, is in Indonesian territory.

A crazy ad from the little Navy that can, for women.

The incredible 57.2 m long U36 (Type 212A batch II) with its bridge fin in the fore-ground, beside the larger 70 m long Invincible (Type 218SG) in Kiel. Type 212A batch II features an increased length for Callisto mast, 4-person lock-out in sail, mounts for Special Forces containers and enlarged torpedo tube, for Special Forces.

Not often can we see two different nation's most modern submarines in the same shot — you can see how huge the sail of the 2,200 ton Type 218SG, is — which means it has space for a 4-person lock-out in the sail of U36.

Invincible is one of four Type 218SG boats ordered under two separate contracts signed between ThyssenKrupp Marine Systems (TKMS) and the Singaporean government in 2013 and 2017. The boat was launched by TKMS in February 2019.

“The Invincible-class submarines are designed for operations in Singapore’s shallow and busy tropical waters. Customised to Singapore’s needs, the new submarines possess longer endurance and can carry higher payloads,” MINDEF said in a statement in June 2020.

“These boats are also equipped with significantly improved capabilities such as longer endurance, higher payloads and more capable sensors,” MINDEF added in its 3 September statement to Janes, stopping short of providing specifics of these capabilities.

I saw the ad the other day and I thought it a right little beauty. It's very well done so BZ to the agency who came up with it.

Singapore’s regional submarine rescue service

1. On 20 Jan 2021, the Indian Navy and the Singapore Navy have signed a bilateral submarine rescue support and co-operation implementing arrangement, was signed at the fifth iteration of the India-Singapore defence minister’s dialogue that was held via video conference on that day.

“The submarine rescue support and co-operation implementing arrangement will allow both navies to extend submarine rescue assistance to each other as well as conduct bilateral rescue exercises and familiarisation visits to enhance interoperability and proficiency in submarine rescue operations”, said Singapore’s defence minister, Ng Eng Hen, in his remarks on the pact.​

2. The Singapore Navy currently operates a fleet of two Archer-class and two Challenger-class diesel-electric submarines and is anticipating the delivery of four new Invincible (Type 218SG) boats from Germany. Singapore also operates MV Swift Rescue, which is capable of conducting intervention, and hyperbaric submarine rescue operations. According to the rumour mill, even Indian Navy submariners think it’s the quietest:

“...EoIs for selection as the chosen OEM. Rubin Design Bureau (Russia) has offered its Amur submarine, Thyssenkrupp Marine Systems (TKMS, Germany) its Type 218 boat, Naval Group (formerly DCNS, France) its Shortfin Barracuda, Navantia (Spain) its S-80 and Daewoo (South Korea) its KSS-3 submarine.​

Of these, only Rubin, TKMS and Naval Group are considered to have a chance...​

Indian naval submariners are almost unanimously convinced of the superiority of the TKMS Type 218, the design of which is optimised for the shallow Baltic Sea – which has similarities with the Arabian Sea, where the waters 40 kilometres off Karachi are just 40 metres deep. The Type 218 is also reputedly the most silent design. However, it is probably the most expensive of the three.”​

3. Meanwhile, the Indian Navy operates four submarine classes, and one 70 m submarine rescue vessel, Nireekshak (15), which is equipped with a six-man recompression and can accommodate up to two deep-submergence rescue vehicles (DSRVs). In 2016 the Indian Navy signed a contract for two DSAR-650L DSRVs with JFD, and the first unit was delivered in 2018.

4. Singapore also provides a regional submarine rescue service to multiple navies — can’t be bothered to dig up the long list of agreements with foreign navies today. DSTA has an article on sub rescue, here and have since 2015, established Joint Standard Operating Procedures for sub rescue, with other navies, like the US Navy.

5. Given that there are over 200 submarines operating in the region, Singapore is doing all it can to avoid a repeat of the Kursk incident (that occurred in August 2000, where all 118 personnel on board were killed), in the South China Sea. We also grieve with KRI Cakra in relation to the unfortunate deaths of two sailors in an submarine egress exercise in 2012 (see: Indonesian Navy to probe death of two sailors in submarine exercise).
OTOH with Canada, while it can be easier to arrange ingress/egress times and routes for RCN subs, the conditions which permit this also make it easier for non-Canadian subs to approach Canadian ports...
6. True, from a certain point of view. Conversely, Singapore submarines just use the traffic noise to hide from "Red Force" sub and observe their activities.

7. In Jan 2021, the Type 218SG is the most advanced boat in the water within ASEAN. The Singapore Navy needed to take some developmental risk, to adopt an all new, orphan class of boat to launch UUVs and embark naval special operations forces, that we hope will remain threat relevant in the late 2030s-to-early-2040s. The 2,200 ton Type 218SG is fitted with two PEM fuel cells and two MTU 12V4000U83 engines, which allows the Invincible-class to stay submerged for about 50% longer than the Archer-class submarines.

8. This bilateral submarine rescue arrangement follows from India’s Prime Minister Narendra Modi, keynote address at Shangri-La Dialogue in Jun 2018, where the conduct of a trilateral naval exercise between India, Singapore, and Thailand was announced. The maiden edition of the exercise was conducted off Andaman and Nicobar Islands in Sep 2019 and repeated in Nov 2020.

9. Defence cooperation under the India-Singapore Joint Declaration on Strategic Partnership signed during the visit of Prime Minister of India Mr Narendra Modi to Singapore in Nov 2015, is an area that has made continued progress. Bilateral defence cooperation between the two countries has been longstanding. Under the India-Singapore Defence Technology Steering Committee, which was set up in Oct 2006, both sides have undertaken several joint research projects in a wide spectrum of mutually-beneficial areas, and are deepening cooperation in unmanned systems and soldier performance. The two navies conducted the first Singapore-India Maritime Bilateral Exercise (SIMBEX) in 1994. The India-Singapore Defence Ministers’ Dialogue co-chaired by Defence Ministers of both countries has increased defence cooperation; and this includes:
(a) the 20 Nov 2019 Letter of Intent that paves the way for Singapore to conduct live firing of missiles like the Spyder air defence system at the Integrated Test Range at Chandipur in Odisha;​
(b) the 20 Nov 2018 exchange of the renewed Army Bilateral Agreement. The renewed Bilateral Agreement enable the Singapore Army's artillery (Exercise Agni Warrior) and armour (Exercise Bold Kurukshetra) training in India, and facilitates increased interactions between both Armies;​
(c) the Jun 2018 Navy Implementing Arrangement Concerning Mutual Coordination, Logistics and Services Support, which together with the Navy Bilateral Agreement concluded on 29 Nov 2017, which gave Indian Navy ships access to Singapore's Changi Naval Base and provides for mutual logistical support and refuelling rights. This agreement expanded and deepened naval cooperation; and​
(d) the Air Force Bilateral Agreement, which was signed in 2007 and renewed on 19 Jan 2017; which enables the Joint Military Training (JMT) at Kalaikunda Air Force Station, India. JMT enables Singapore’s advanced F-16s to train alongside India’s SU-30MKIs.​

Wait. Is Invincible undergoing sea-trials in ASEAN waters? I thought it would undergo trials closer to Kiel.
He said "in ASEAN", not "in ASEAN waters" - subtle difference.

"Sea trials" with TKMS for submarines usually means off the coast of Norway in the North Atlantic - they also have facilities there - as well as some limited standard tests in the heavy-traffic Western Baltic. Invincible has been photographed during the latter.

Can these USVs mount equipment to detect underwater vehicles such as drones or submarines? I saw an article about them being able to do mine detection and disposal. That and the recent article posted in the Indo Pacific thread about Chinese submersible drones made me curious as to the flexibility of their underwater detection capability.

Actually, I wasn't aware of this. Thank you. Then again, I do have a hard time keeping track of the various USV, UGV, and UAV models used by the SAF.

Above is a video number 7 of 8, showing RSS Supreme’s participation in RIMPAC 2020; held in the waters off Hawaii from 17 to 31 Aug 2020 (local time). Exercise RIMPAC 2020's Sea Combat Commander (Task Force 2) and Commander Task Group (TG2.1) Senior Lieutenant-Colonel (SLTC) Choo Jui Yeang said, "Ex RIMPAC provides the RSN with a unique opportunity to train and learn with established navies from around the world. While this... exercise is smaller in scale because of COVID-19, we are glad to be here at Ex RIMPAC undertaking command roles as this allows the RSN to sharpen our capabilities.”

Exercise RIMPAC 2020 involved 22 ships, one submarine, multiple aircraft and approximately 5,300 personnel from 10 nations.

U.S. and Singapore navies join together in the waters around Guam for exercise Pacific Griffin 2021, held from 21 June to 7 July 2021, for advanced maritime training to enhance combined proficiency at sea while strengthening relationships between the two navies.

"Exercises like Pacific Griffin emphasize cooperation while building competencies in a complex and technologically-advanced training environment," said U.S. Navy Capt. Chase Sargeant, commander, Task Force 71. "This exercise demonstrates the trust and expertise we have built over the years with the Singaporean navy through increasingly complex and integrated training and live fire events.”

This is the first time Singapore’s littoral mission vessel RSS Fearless is showing off its ability to deploy a relevant mission module for this complex 2 week long exercise. China’s rise and the design range of its air-to-air missiles (and the PLA(N) strike complex ensures that all air forces and navies need to evolve at a system design level). The F-35B to be acquired in 2026 and beyond for Singapore has four basic missions: air superiority, or offensive and defensive counterair; suppression or destruction of enemy air defenses (known as SEAD and DEAD); close air support; and strategic attack against high-value strategic and mobile targets. Block 4 also adds a fifth basic mission, Winter said: “extended surface warfare.” Upgrades will enhance radar “for maritime surveillance, identification and targeting.”

(i) RSS Fearless is tasked to deploy modules for UAV (and in future USV for multi-static active sonar use to hunt and defend against the Los Angeles class attack submarines playing the role of Red Force).​

(ii) Growlers are being used simulate for the fight for dominance of the electric spectrum to increase the level of difficulty for the F-15SGs in their maritime strike role. Certainly in the late 2030s, F-15SG’s CONOPS for WSO training program or EA-18G CONOPS for training the 2nd crew member, both in a maritime strike/SEAD role is going to be increasingly copied or replicated in a systematic fashion by various countries in the Indo-Pacific.​

Let me list some of the participating aircraft, ships and submarines in Pacific Griffin 2021 — the most complex, warfare-centric bilateral exercise between the navies.

Naval assets include USS Benfold (DDG 65), USS Springfield (SSN 761), USNS Amelia Earhart (T-AKE 6), RSS Tenacious (71), RSS Stalwart (72), RSS Fearless (22), training ship MV Avatar (serving as a high value target), and naval divers. A P-8A Poseidon, EA-18 Growlers from Electronic Attack Squadron (VAQ) 132, RSAF F-15SG and F-16 fighters and a G550 Airborne Early Warning aircraft are also taking part in the exercise.

RSS Endeavour sets sail to deliver Corvid-19 Aid — Part 2

2. RSS Endeavour reaches Tanjung Priok Port, North Jakarta, Indonesia, with its life-saving aid package to help fight CORVID-19 from Singapore.

3. 9 provinces had reported hospital bed occupancy above 80 per cent, including Jakarta and West Java. The government was in talks with industry about letting authorities have their excess capacity, as well as looking at imports, Budi said. With many Indonesians unable to get hospital beds, independent data group Lapor COVID-19 says 453 people have died from the coronavirus in self-isolation since June.

4. Senior minister Luhut Binsar Pandjaitan, who spearheads the emergency response, on 14 Jul 2021, said oxygen supplies were well managed, with more than 1,500 oxygen generators expected to arrive from Singapore and China. More than 2,000 newly graduated doctors and 20,000 nurses would soon be deployed to hospitals, he added.

5. As aid from 10 countries pour in, Indonesia is reporting over 47,899 daily Covid cases (on 13 Jul 2021), surpassing India, which is now witnessing a dip in the number of daily infections. On 7 July 2021, Indonesia expanded nationwide curbs to battle its deadliest Covid-19 wave. With the spike in cases, authorities unveiled plans to order liquid oxygen and tens of thousands of concentrators from abroad to treat patients suffering from the respiratory disease. The daily need for oxygen has reached 1,928 tons a day. The country’s total available production capacity is 2,262 tons a day, according to government data.

“I asked for 100 per cent of oxygen go to medical purposes first, meaning that all industrial allocations must be transferred to medical,” said Pandjaitan.​
