TKMS Launches Singapore's 4th Invincible Class Sub

thyssenkrupp Marine Systems (TKMS) on April 22, 2024 launched RSS Inimitable the fourth Type 218SG Invincible-class submarine for the Republic of Singapore Navy (RSN) at a ceremony in Kiel, Germany. The launch was attended by Teo Chee Hean, Singapore's Senior Minister and Coordinating Minister for National Security, and Boris Pistorius, Germany's Minister of Defense.

As I mentioned in my "State of ASEAN Submarine Forces: Singapore" article in June 2023, with the introduction of the Invincible class, Singapore will have undergone three generations (Challengers, Archers, now Invincibles) of submarines in the space of 25 years. 

After a contest between TKMS and Naval Group (Scorpene), TKMS was awarded a contract for two boats (then called Type 218SGs) in 2013, and a second order of two in 2017. Construction, in Kiel, Germany, on the lead (renamed Invincible class sub) RSS Invincible, started in 2014 - it was launched in 2019. Then the second, RSS Impeccable and third, RSS Illustrious, were simultaneously launched in 2022.

TKMS states that the Invincible class, at "70m length and around 2,000 tons" displacement, currently are the largest submarines the yard has built. If this statement is true, then the Invincibles are slightly larger than their Israeli cousins, the Dolphin II (68.6m length, 2,050 tons surface displacement), through the upcoming Type-212CD class boats that entered production in September 2023, and the  Israeli Dakar class, ordered in 2022, will be larger boats.

RSS Inimitable is the fourth and last of the class (as stated in a press release by Singapore's Ministry of Defense). TKMS will hand over the sub to the Republic of Singapore Navy in 2025, after testing and outfitting.

RSS Invincible still remains in Kiel for RSN crew training at the German Navy's Submarine Training Centre, at Eckernfoerde Naval Base. TKMS has also signed an MoU with Singapore's ST Engineering to 'enhance the Type 218SG Type 218SG submarines over their operational lifetimes". This further enhances the relationship the RSN and ST Marine have established with TKMS and the German Navy.

RSS Impeccable arrived in Singapore in July 2023 (see my article) for local sea trials and workup, and will be fully operational and commissioned later this year. This will likely coincide with the retirement of the RSS Conqueror, a 57-year-old boat that has been in Singapore commission for 20 years.

Singapore media claims the RSS Inimitable will be delivered to Singapore by 2028.

Aussie SemiAutonomous Weapons Forge Ahead

Following the early and within budget Ghost Bat and Ghost Shark success stories comes a rapid SemiAutonomous patrol boat development - see APDR's article. All these semi-Australian projects are forging ahead - all unmanned-SemiAutonomous-remotely piloted technologies. These terms sound contradictory, but all these represent multi-node, distributed technologies with some artificial intelligence input.  

The above projects are in such contrast with almost inevitable failures in Australia's MANNED vessel and submarine projects. 

The Australian Government should look hard at cancelling more manned "Shipwrecks in the making". All Australia's Manned naval projects seem to be 10 years late at 3 times original cost estimates. 

Manned projects might increasingly be seen as gratuitous career promotion opportunities for too many armed forces offices seeking combat overseas. Some members of my family directly recognised this. We need more computer experts who can operate systems remotely. 

The studies of how to safely weaponize SemiAutonomous systems is a major study of Five Eye software and computer hardware specialists. I think a subset of this study are some  activities under AUKUS Pillar 2. Having some men in the loop makes such systems safer. 

eg. the US showed the way with weaponized Predators and Reaper UCAVs. On the whole they functioned extremely well in the Middle East, Afghanistan and less well known theatres. These US UCAVs were/are being remotely piloted from Creech Air Force Base, Nevada, with in the loop approvals coming from Washington DC, and forward observation posts in theatre. The public don't/didn't hear about the 1,000s of  successful weapon release and/or reconnaissance Ops, only about the rare targeting mistakes. Reapers over Yemen might now be very much the go.

So Australia is catching up and will probably save A$Billions avoiding totally manned traditional weapon solutions.

Did Israel throw ROCKS at Iran?

I would like to leave the geo-political issues of the 2024 Israel-Iran confrontation here and here to political experts (I only have a major in international relations). Though my opinion is that Iran has its own perception as a major player in the Middle East, and had to 'demonstrate' its power to strike Israel.

300 Iranian one-way UAVs, cruise missiles and ballistic missiles are a lot. It would overwhelm most unprepared nations, and cause thousands of casualties. 

The Iranians did prewarn the Saudis, Kuwaitis, Jordanians and Iraqis. So Israel, the US and NATO had plenty of warning to set up combat air patrols and pre-position their warships that have SAMs and AAA. We are also not certain which weapons Iran used, and they could have used older weapons that had a higher chance of interception or failure. 

But people were going to be killed - no one, including the IDF, expected Israel's integrated aerospace defense system, in conjunction with allies' fighters and air defense, would stop 99% of the weapons.

Nevatim Airbase (believed to be a storage site for nuclear weapons) is probably one of the better-guarded sites in Israel. So Iran scoring a couple of ballistic missile hits on it is high on Iran's 'achievement' list, not the fact that little damage was caused. The one video of incoming I have seen shows ballistic, unguided munitions, so they may have not been a priority for Israel's Iron Dome or David's Sling SAMs.

I think Iran lucked out - with little damage and no deaths in Israel. Israel could have  responded in a number of ways, from using a remote control machine gun within Iran to assassinate another Iranian nuke scientist, to storm of nuclear-tipped Jericho missiles.

Instead the IDF choose to throw 3 ROCKS at Iran.

The Rafael ROCKS.

The ROCKS Autonomous Extended Stand-Off Range Air-to-Surface Missile was first shown at Aero India 2019, and according to its sales brochure, has anti-radiation features and uses an Inertial Navigation System (INS) to work in GPS-denied areas.

ROCKS is likely a variant of Rafael's Sparrow Ballistic target missile, which is a two-stage missile air-launched from an F-15. As this article in the Financial Times shows, spent first-stage boosters were found in Wasit Province, in eastern Iraq, about 560km West of the Isfahan target area, on the night of Israel's retaliation.

The Financial Times article highlights IDF attacks on Syrian air defence positions. This was followed by Israeli aircraft crossing into Syrian airspace to fire the air-launched ballistic missile(s) at the Isfahan Air Base. 

There were early Iranian reports that it shot down 3 Israeli drones over the Isfahan area. If there were any such drones they were probably coordinated to distract or EW lure Iranian air defenses to mask the real ballistic missile action.

The Times of Israel published an article based on a New York Times report (paywall) that claims Iran did not detect the incoming missile, and it damaged a 30N6E2 Flip Lid target-engagement radar of the S-300PMU2 battery protecting the airbase.

So Israel basically replied to Iran: "Hey, you fired 300 weapons at me, 1% hit and caused minor damage, while I fired 3 or 4 missiles that penetrated your air defences and took out an S-300 radar at your most sensitive airbase/facility. You wanna play a game of missile polo? I have nukes and lots (probably) of conventional Jericho and Popeye Turbo missiles, so u wanna bet on whether Tel Aviv or Tehran ends up the smoking radioactive crater?"

So I hope that we are backing off (again) from nuclear brinkmanship (Pete predicts there will be a second strike on Iran that might precede Israel's invasion of Rafah, in Gaza). But the true winners of this missile ping-pong will be Rafael and Raytheon, who will enjoy massive sales of air defence equipment this year - as countries replenish expanded stock, and to better protect themselves.

Update 15/4/2024 - the Indian Crystal Maze 2

Two days after the IDF strike on Isfahan, Indian media reported that the Indian Air Force successfully test fired a Crystal Maze 2 ALBM from a Su-30 MKI fighter. 

Crystal Maze 2 is an 'Indian-developed' version of the ROCKS, and it is currently unclear if India is procuring this missile for Rafael, or testing an Indian-produced variant. Nevertheless, it is clear that India has noted the use of ROCKS by the IDF and has decided to disclose that India now has the same ALBM capabilities.

ANZAC Day 2024

Australia and New Zealand commemorates ANZAC Day on April 25th each year. It is our secular "holiest" day. The day remembers the sacrifice of troops of the combined Australian and New Zealand Army Corps (ANZAC) in World War One and of Australians and New Zealanders who fought in all later wars. 

The following are songs and photos I've put together to remember them.

Anzacs (or 'diggers') at Gallipoli in a rare quiet moment in 1915. Gallipoli's field Hospital tents were  constantly being shelled by the Turks, because the Turks knew (and it was true) that ammunition was actually being stored in some of those tents... Much safer for the wounded to be taken to nearby ships and then to nearby islands, like Lemnos.

My grandfather copped a lot of X-rays (decades later dying of cancer) as there was no lead operator shielding, only a canvas curtain. My grandfather then shifted to Gallipoli later in 1915.

This great song And the Band Played Waltzing Matilda by Eric Bogle is about the life of a digger wounded at Gallipoli.

There is a myth that true Anzacs were and are all front line infantry. Some other occupations were actually more dangerous than infantry. Pilots often suffered the highest casualties of any service with about a quarter dying in training then another quarter in combat. Submariners, were often in the greatest danger both from the enemy and also from accidents (together killing about a half of submariners in total). Here is the Navy Hymn for Submariners.

Here and above the hymn Abide With Me is traditionally sung at ANZAC Day services. The singer is Hayley Westernra from Christchurch, New Zealand.

 The song I Was Only 19 (by that under-appreciated Australian group Redgum) is in memory of Australians who fought, died and were injured in Vietnam (early 1960s to 1972).

Here and above. I think Eric Bogle’s The Green Fields of France (also known as "No Man's Land" and "Willie McBride)  (above) is the best anti-war song ever written. As a haunting poem, march, song of love and injustice it is a fitting anthem to remember the men and women, living and dead, who are our people,  our Anzacs.

A Remembrance poppy.

Collins LOTE Now Budgeted. Saab, LM & MTU.

The Collins Life of Type Extension (LOTE) has been little discussed of late drawing suspicions it may be cancelled like many RAN ship and submarine projects. However I consulted the Australian Submarine Agency (ASA) website which has recently added more certainty to the LOTE project, budget and all. 

See https://www.asa.gov.au/aukus/collins-class-submarines    

"...Australia's Collins Class submarine fleet will undergo a life-of-type extension (LOTE) at Osborne shipyard in South Australia. 

The LOTE will keep the Collins Class submarine operationally capable and available into the 2040s, supporting the transition to Australia's nuclear-powered submarines.

Budget: $4.3 - $6.4 billion

Timeframe: First LOTE scheduled for mid-2026

Industry: more than 1500 jobs

Location: Osborne South Australia (LOTE) and Henderson Western Australia (sustainment)" 

PETE COMMENT

The estimated range of the Budget: $4.3 - $6.4 billion (Australian dollars) is clearly quite broad. 

Some defence commenters, with some accuracy, claim it is best to triple an Australian government defence program budget estimate due to the many uncertainties impacting multi-year projects. Such uncertainties include:

-  shortage of skilled shipbuilding labour in the "white" Western world generally (meaning higher wages than intended are required to attract labour). No such shortage exists in Northeast Asian countries.

-  higher than expected inflation, which has already hit Australia since January 2023

-  project deadlines not met, part caused by:

-  the Australian defence industry tendency to add many more upgrade items "bells and whistles" than originally envisaged.

So the new "Rule of Triples" ((you saw it coined here first) in Australian budgeting may mean (with 2 years of LOTEing for each of the 6 Collins = 12 years) by 2038 the budget may well balloon to between A$13 Billion and A$19 Billion.

Some might now say - "well if LOTEing costs that much why don't we buy/build a new class of Interim Conventional Submarines?

To which I counter: 

It would take about 3 years (ie. by 2027) for the Australian Government to summon up the support for New Conventional Submarines.

Then 2 years minimum to choose the foreign main contractor (2029).

Then the Build in Osborne Political Reality (ie. no whole sub foreign build) pans out to Signing the Contract (2030).

Then the always slow Osborne build takes 15 years (2045) until first of class is launched.

Then 2 years ironing out working up bugs until Commissioning first of class (2047).

Then each successive submarine in a class of 6 would take around 18 months to build ie. launched in June 2048, Dec 2049, June 2051, Dec 2052 and June 2054).

The kicker is these New Conventional "Interim" Submarine timing realities would directly clash with the SSN-AUKUS timings which may start to be built in Osborne in 2042. Osborne simply wouldn't simultaneously build 2 types of submarines unless in a runup and during World War Three (maybe China and Russia vs Democracies including Australia). But I digress.

So LOTEing makes sense especially if Saab Kockums is involved, in part because Saab did the Mid-Life Upgrade of Sweden's Gotland-class, similar to Collins in significant ways. A new Combat System for the Collins, integrated by Lockheed Martin, may be a high price aspect. New diesels needed, probably MTU 4000s, will also be expensive. Submarines are always expensive.

Israel's Target List eg. Iranian Nuclear Facilities

Over the last 12 hours Israel began missile strikes on Iran, initially targeting an air base https://en.wikipedia.org/wiki/2024_Israeli_strikes_on_Iran near the Isfahan/Esfahan nuclear research center 400km south of Tehran. Depending on the Iranian reaction Israel may escalate the conflict to targeting Iranian nuclear sites over the next few days.

Created since the Israeli strike here and below is an excellent explanatory video from University of Pittsburgh Political Science Professor William Spaniel.

Possible Targets

The maps below indicate Iran's nuclear sites. The nuclear facilities in Tehran itself are particularly problematic because they are believed to be deep dug under that highly populated city. Is Israel prepared to justify the high "collateral" deaths of perhaps 1,000s of Tehran civilians? 

Also hitting surface reactors might cause Fukushima or Chernobyl style meltdowns and explosions spreading clouds of radioactive dust throughout the region. In the case of the very large Bushehr reactor complex, on the Persian Gulf, radioactive air and water dispersal might impact populations in the Gulf States including Kuwait, Saudi Arabia and the UAE. 

Overall concerted air attacks on Iran would increase the world oil price sharply because the high oil producing Gulf States it between Israel and Iran. I filled my car's fuel tank yesterday - just in case. 

Other high priority Israeli targets may include Iran's leading politicians and generals, regular army, navy and air force bases and Revolutionary Guard bases.

Particularly drone missile bases. 

Any chemical weapon production and warhead facilities would be very high priority targets. https://en.wikipedia.org/wiki/Iran_and_weapons_of_mass_destruction#Chemical_weapons
 

Above Map of Iran's highest priority nuclear facilities. This includes the research complex at   Isfahan/Esfahan (from which Submarine Matters' site-meter years ago picked up Iranian reader interest in computer simulations of nuclear weapon explosions).

See a more detailed nuclear facility map below (Courtesy Business Insider https://www.businessinsider.com/map-of-the-day-iran-nuclear-sites-2010-6 )

Since 2014 Iran has been near nuclear weapon breakout status - with the three components being:

- substantial stocks of semi-enriched uranium (perhaps between 5% and 20%), https://en.wikipedia.org/wiki/Enriched_uranium#High-assay_LEU_(HALEU)  which could become bomb grade (90+% HEU) within weeks/months using Iran's thousands of centrifuges and possible hidden laser enrichment capability.

- delivery means - including the Sejjil http://en.wikipedia.org/wiki/Sejjil solid fuel IRBMs within range of Israel, and

- enough nuclear device plans and components acquired from Pakistan's A. Q. Khan network to have constructed crude fission devices (minus the HEU and/or Plutonium explosive) around 2006.
