The Future of the Submarine - Emerging Threats, Sensors & Transparent Oceans

[@PerunAU]

I have tried to keep the number of bad jokes to a minimum - this is a serious deep dive. More seriously, this isn't the first time we've seen predictions of the submarine's upcoming demise, and thus far they've continued to dominate despite each technological change thrown at them. That said, there are a wide array of developments on the horizon, and they may force submarine forces the world over to adapt to survive or thrive. Hope you all enjoy, and I'll be back with you again next week

[@DerekWoolverton]

I was working with the Singapore university remote sensing lab back in the 90s, and there was an Australian researcher who was studying the surface characteristics of undersea current flows (ocean floor currents). His software was actually detecting the ocean surface "choppiness", based on how it scattered the SAR signal. But he was annoyed that his software kept picking up spurious flows across various parts of the ocean where there weren't any undersea features that would lead to sea floor currents. Finally one of his American compatriots leaned over and said, "Shhh. Those are submarines."

With that there is also how you split the slides between the two in a way that allows both the image and the text to pull attention without overshadowing the other. I believe at the beginning you also more often copy pasted tables and graphs into your slides where now I notice that there are a lot more figures that are made to fit with the visual style you have developed for these slide shows.

Something I find annoying is that people frame discussions of a platform’s viability in terms of the capabilities of a sensor, weapon, etc. that might target it, ignoring that those systems need to be on platforms of their own, and will be targeted in turn. I very much appreciate that you highlight that more capable weapons and sensors make submarines more dangerous too.

[@mangalores-x_x]

More importantly the question is not what weapons can target a platform, but what else can do the job of that platform better, cheaper, more reliably. Everyone thinks tanks are obsolete because they get blown up ignoring that tanks were blown up on the first day of their deployment in ww1. It's not hard. Drop an artillery shell on them. And that is what we still do 100 years later. Drop artillery shells on them. The question is what can replace what tanks do? And there all other options in place of tanks get blown up by even more stuff than tanks can be. In case of subs the question is not what can detect it, but what can replace its capabilities.

[@IsaacHenryinAK]

Great episode! As a retired submariner I try to follow the developments in the world I am very familiar with. Admittedly, it isn't as familiar as it once was. Submarines and detection systems are a quantum leap ahead of what they were in the years I spent sitting in sonar hunting 'bad guys (77'-95'). In fact I wonder if sonar itself is soon to be obsolete. Or at best, you won't be listening for the sound of a submarine but rather the hole in the ocean where there is no sound. We did have some sneaky little tricks to find those 'bad guys'. We often would look in areas of heavy biologic activity. Something stirred up those fish and hiding in a noisy area was a common strategy. Lumbering old merchants were also suspect as a boomer could use that high noise field as cover while said merchant transited through their patrol box. But the real trick was to catch them doing something that made just the wee tiny noise that only lasted a few seconds. Catch a 'bad guy' doing some housekeeping evolution and you basic had him by the short hairs. Guess that may not be true anymore.

[@SkyHawk2137]

@@Chrischi3TutorialLPs Honestly, I don't think the Long Lance can be rated higher than A. Just too dangerous to it's launching vessel between the pure oxygen and more shock-sensitive warhead making them all too liable to detonate if the launching vessel came under attack before it was in position to launch the torpedoes at an enemy. Right at the top of A Class mind you because despite that flaw, it was an absolutely amazing advancement. But I'm honestly unsure if any torpedo in WW2 rates S Class because of the compromises and design decisions chosen even if we don't care about any post-WW2 technology effecting the chart. Basically a case of WW2 having all the technological developments needed to produce an S or even SS class torpedo but said developments were scattered across the various sides rather than concentrated in one place. Or whoever had the developments couldn't make use of them due to design culture, industrial difficulties or material limitations. The big one off the top of my head would be that the Long Lance was given that warhead using a slightly more powerful explosive than TNT, despite it being much more shock sensitive. If they'd stuck with a TNT warhead despite the 7% loss in power (at least that's the number I've found) then I'd say it absolutely would be an S Class torpedo design because having 'just' the one flaw of the compressed oxygen system is more or less 'don't expect perfection in the real world'.

[@2paulcoyle]

It wasn't bad. The US Navy was bad.

[@Chrischi3TutorialLPs]

@@2paulcoyle Yeah it was bad? The list of faults in the torpedo include, but are not limited to: The magnetic detonator being poorly calibrated and sometimes going off at random The contact detonator having nearly zero detonation chance if fired in a textbook attack The depthkeeper malfunctioning and causing the torpedo to run deep due to poor placement The gyroscopes sometimes locking up and causing the torpedo to run in circles The main reason for these faults existing is that the torpedo hadn't actually been tested before the war's outbreak, in no small part because Congress decided that testing was too expensive.

[@matsu_moshi9867]

This is timely. Thailand just decided to continue it's submarine program with the Chinese diesels. Lemme explain : We have had submarines before in the form of the Matchanu class subs, built in Japan before ww2. They were decommissioned after the war due to obsolescence and lacking spares. The Royal Thai Navy would attempt to procure submarines two more times without success. Fast forward to 2016, the military junta under Prayut Chan-O-Cha opened a bid for sub procurement. Many companies from all around the world submitted proposals but for the given budget, they could only offer two boats, except China. They offered us an irresistable deal, buy two get one free along with spare parts support for 8 years, and other weapon systems that the west wouldn't sell like smart mines, whatever those are supposed to be. So the government took out a loan for the program (thai government fiscal things, not a big deal). The contract for one boat was signed with the Chinese Shipbuilding and Offshore company (CSOC), and the keel of the S-26T submarine for the RTN was signed. The S-26T is basically a Yuan with minor changes. A major problem occurred. CSOC did not get an export agreement from MTU, the German company who were to supply the diesels per the contract. And thus, work was stopped.The issue was brought to the RTN's attention in 2018, four days after paying the second installment of cash for the boat. Political hot potato ensued, and then covid hitso things went away for a bit. The Chinese offered the CHD620 to replace the MTU diesels which they couldn't get at this point, despite the current Thai PM going to Germany and talking to Olaf Scholz about it. The CHD620 is a Chinese designed and made diesel engine for submarines. It hasn't seen any use on subs other than on the Pakistani subs which they took delivery of in late April , so the RTN was sceptical about it. After the engine was certified by a 3rd party in about 2022, the RTN asked to send a delegation to double check the diesels. CSOC responded thus : "No, it's a waste of time.". There would be proposals to solve the issues periodically such as canceling it and getting a refund, changing the contract to a frigate or a few OPVs , or buying fertilizer (there being a shortage of fertilizer at the time due to the russo ukrainian war) but none of them went anywhere. In the intervening time, the navy did funny things with the submarine budget, diverting part of it to buy the Landing Transport Ship HTMS Chang, part of the reasoning being for her to act as a submarine tender...for some reason., and started building support infrastructure for the subs. Then, they folded the frigate budget back into the submarine budget so now the frigate Bhumibol Adulyadej doesn't have a sister ship. Parliment did not pass a new budget for the second ship of the class, tentatively named the Anandamahidol after King Rama the 8th. And the government has had to pay interest on the loan amounting to 27mil USD. After much political hot potato, the Defense minister took a flight to china to discuss the matter with CSOC. He came home empty handed it seems. Reps from CSOC came to negotiate with us between the 14th and 15th. On the 16th, the Defense Ministry announced that the submarine program shall continue with CSOC giving us 5mil USD worth of spares and training equipment. Delivery is to be expected in 2028. This is one cursed procurement cycle.

Unless we get to a point where space travel is possible or governments start thinking about putting secret permanent underwater military bases or missle sites 20:10 I don't ever see the submarine becoming obsolete. If I had my own country and could only pick one type of hardware to use for my navy I would always pick the submarine. The stealth, speed, firepower, endurance, and ability to move assault teams. Nothing compares to a nuclear sub. Great video as always keep up the great work sir. We all really appreciate your efforts !!!

I didn’t realize that LiDAR had gotten that close to the end goal of being able to count ants from space already, the incredible leaps in technology over the last few decades has been incredible, I usually hear about LiDAR and magnetometry and ground penetrating radar when I watch content about archeology and the difference between the results from the technology that was used in the eighty’s and ninety’s on some of time team’s earliest episodes and the technology being used today is amazing and the tools that are used to do the work have gotten so much smaller and easier to use as well, but I didn’t realize it had military uses besides being able to provide better up to date topographical maps.

Geometric stealth on submarine is intended to defeat active sonar, the mechanism is more for less the same as to how geometric stealth on aircraft defeat radar. It does not help with passive sound and other signature.

⁠@@ianwhitchurch864You can’t logically call that a major issue when you consider the alternative, which is getting popped like a balloon by said ASW helicopter. The only time those could and would be used is when the helicopter is almost on top of them. And, generally if an ASW helicopter is up in the air and close to you, they are already certain there is a submarine in the area and probably also have a decent idea of where it’s at. Either that or they’re very lucky.

Recently been obsessed with the Ohio class SSGN’s and the utility of conventionally armed submarines, this vid could not have come at a better time

[@chrisstrawn4108]

SSNs will be key to containment strategy if China invades Taiwan. China is working on overland routes to get around this, but until then fast attack boats armed with Harpoons, Tomahawks and ADCAPs are the strategic fulcrum.

[@GrahamCStrouse]

@@chrisstrawn4108We need cruise missile submarines more. We don’t have nearly enough fast attacks and their magazines are too shallow.

[@Shaun_Jones]

The Ohio SSGNs might not be around much longer; the Navy is looking to replace them with a larger number of the Block V Virginia-class boats with the Virginia Payload Module. Makes sense to me, there’s no guarantee that an SSGN will have time to launch all 154 missiles during a peer conflict, not to mention a relative lack of targets that would require that many Tomahawks, having fewer missiles on more submarines lets you have strike capability in multiple places at once; and it would allow crews and their boats to be cycled out more often, since the current SSGNs are on the same patrol schedule as the boomers, meaning long duration patrols with very few port calls. Besides, the VPM tubes can also replace their 7 Tomahawk cells with three tubes for hypersonic missiles if the mission requires it.

[@ianwhitchurch864]

@@GrahamCStrouse Not having enough fast attack boats is a direct result of overinvesting into too-expensive nuclear attack submarines. At the end of the day, quantity has a quality all of it's own, and if you only invest in the high end systems, you don't have enough quantity.

[@solarissv777]

​​@@Shaun_JonesI would say that the cost of nuclear submarines is a big problem: you just cannot produce enough of them. IMHO the US should look into conventionally powered cruise missiles carrying subs as well, especially since new Li-Pol batteries may allow to forgo AIP. Also, if they're gonna be considered more ships than subs - operate mostly under snorkel and with a friendly fleet, less reliant on stealth and more on active defenses, not replacement for Ohio, but for Ticonderogas. You put most of the land attacking missiles on them, and load more AA onto the surface ships. Add little AA capabilities to the subs as well (e.g. Germans developed the Iris T version, which can be launched from subs at aerial targets). These submarines will still be way stealthier than even Zumvalts, while being way cheaper than nuclear underwater missile trucks. Additionally, they would need much smaller crews and be simpler, e.g. you may forgo water desalination and just get your fresh water from the friendly surface ships, while surfaced. And even provided all these simplifications, they would still be able to switch to batteries, dive, and be potentially, even stealthier than SSBNs, albeit for a limited amount of time, but just enough to conduct a first strike. The problem, though can be to keep up with the fleet. I wonder, if gas turbines can work with a snorkel?

An hour long video that kept me awake all throughout, well done mate on making this so interesting. Love your work. Subscribed and liked

[@StoccTube]

I recently read an MIT paper on WiFI signal disruption being used to train an AI on people in a room. First they combined cameras and people walking or posing in a room. They fed the AI the WiFi signal detection data at the same time as video feed. After sufficient training time, the scientists took away the video feed and asked the AI to represent the poses of people in the room as they changed positions. The AI totally nailed it. This is very easy to find via a Google search and there more coverage than just the MIT article. That is some “Batman” level tech. Imagine police or military being able to track people (you) in the room you’re in just by detecting disruptions in the WiFi signal as you move around! Not only is the ocean likely transparent by 2050, what you’re doing in the bathroom might be too!

[@robertsneddon731]

The understanding in most military intelligence circles is that SSBNs stay close to home and are usually under an umbrella of local surface warships and aircraft most of the time. The British and French SSBNs stay in a million square kilometre box in deep water in the Bay of Biscay, the Russian SSBNs operate in the far north of the Arctic Ocean and just off the coast of the Sakhalin and Kuril islands and the US fleet operate near Hawaii and Pearl Harbor to cover the Pacific area and around Newfoundland for their Atlantic patrol area. There's no tactical or strategic benefit for them to go far from home given the published range of SSBN missiles.

[@death_parade]

Bastion strategy. Indian SSBN use Bay of Bengal as their bastion. Hemmed in by Indian peninsula on one side and Indian islands of Andaman and Nicobar on the other side, completely dominated by Indian Navy's Eastern fleet. Almost impossible for Chinese or Pakistanis to run ASW ops there.

[@Warmagon]

I thought there was a strategic benefit at least at some points. If you want to have a decapitation or disarming strike ready, the missile subs need to close by their targets for less flight time. Get the flight time low enough, and there's the potential for the nukes to land before the opposition confirms the launch and responds, and then they lose command and control and/or their launchers so hopefully there's not a retaliatory strike... Of course, this is a very dangerous seeming "benefit."

[@robertsneddon731]

@@Warmagon Nearly all Submarine-Launched Ballistic Missiles (SLBMs) today are solid-rocket propelled and that mean they are going to burn for a fixed time before they are exhausted. That means that either they go way up high before the warheads come down close to the launch point or they fly a flatter trajectory over a greater ground distance but in either case their ride to glory takes about the same time from launch to impact. Better to stay well away from hostile shores and ASW air cover when the launch order is given. SSBNs are a retaliatory second-strike force in the main, a hidden assassin that can strike from an unknown location after hostilities have begun and your cities are dying. It's why two of the British Continuous At-Sea Deterrent SSBNs were named "Revenge" and "Vengeance".

The Transparent Ocean is a bit of a misnomer, the ocean is not really one thing, its a dynamic system of ever changing temperature, density layers with multidirectional flows and acoustic characteristics... in terms of signal processing its always been a nightmare and will continue to be for some time... Small drone like subs that can act as remote sensors that switch to a torpedo when locating a target is probably the great change that is coming with the "Main" Sub being more like an underwater aircraft carrier/tender and possibly fully remote as well.

Alot of this I knew already, but getting to understand why there are people saying the oceans could be transparent was very interesting, and as I suspected the case for the obsolescence of the submarine is overblown. I think the main factor for the people pushing it is really that subs are very expensive and somewhat worthless in peacetime, which is the majority of time. So if you want to free up a few hundred billion dollars over the next decade you could point out that we haven't been using them anyway and they'll have no advantage in the future. This is a alot of truth mixed with alot of wishful thinking but it makes sense why people might end up in that camp. That said, if anything the West needs MORE subs not fewer, in a shooting war there is no substitute for subs.
