- The Collins Class remains one of the most capable, and deadly, conventional submarines in the world. This documentary takes a look at the boat's origins, capability and future, including an overview of its sensors, systems and weapons, to give you a quick low down on one of the Australian Defence Force’s most lethal assets.
Getting some questions on where I got my information on this video. This is the primary source material, although some other reports were consulted, if any one is interested in reading more:
"Lessons of the Collins Class Program for Improved Oversight of Defence Procurement" Parliament of Australia, Derek Woolner, 2001. www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/rp0102/02RP03
Check out the section on submerged performance and indescresion ratio.
I knew the class had its troubles, but didn’t know there where so many boats in the class. Cant wait to see what the new ones can do. Your video goes a long way to explain how a Collins got so close to sinking a USA carrier in war games. Nice to good buddies with USA for those sweet sub systems.
Also love how the crew issue was due to mining boom. I guess if happy to stick ourself down a big hole and maybe be crushed, your suited to bury yourself underwater and maybe be crushed.
Bloody champ mate
Keep going
Such good info
I try to keep up-to-date on F35s
And ur video was the best easy
This vid was exceptional too
Thanks heaps

This is a right proper video about Collins-class submarine. VERY Well Done hypohystericalhistory.
Hey jive! Very high praise my friend. Hope you’re doing well.
I know this, the Collins class has a problem with depth. The the American kills were taken in 16 fathoms ( Gulf of Carpentaria ). The field of work these next subs will be in, is Asia with some of the deepest terrain in the worlds oceans. So we need the subs to go deep and long. Also you can not produce the steel plate in Australia for these type of sub unless you build a new steel blast furnace with extrusion rollers wide enough to produce steel plate at the size of 40 or 20 meter long by 10 meter wide at the minimum. Now the new sub are Virginia Class, Yes. These Virginia class sub are 100 meter plus long by 13 meter diameter so the circumference is 3.214 x 13m = 40 m plus to fabricate a ring in one piece. So this will make one of ten or more 13 m diameter x 10 m wide steel rings with one welded seam. If you used the 20 m long plate the rings will have two welded seams. 10 of these 13m x 10m ring welded together make a 100m long x 13 meter vessel "The less seams in a pressure vessel or sub the better" Plus this new steel plant has to transport these steel plate section this size and weight to the shipyard so it best to built the new plant next door to a ship yard with a deep sea port. Plus you have to have the Press machine with the enough width and enough tonnage capacity to roll these over size plate which there are none in Australia. You can use the heat and shrink method the Japanese use but the skilled tradesman are lost to Australian manufacturing. This method is also the best method of fabricating because it does not fractures the molecular structure of the steel plate has much as mechanical pressing . So under pressure it can go deeper and longer than a sub haul made by mechanical pressing. I say the Australian should off went with the Japan made Sub made in Japan. But since this video was made the Australia Government has pull out of the French Sub deal and got the OK to buy 12 Virginia Class nuclear powered from the USA. Which in the end will be fabricated in the USA because of all the above. I don't know how no real investigative journalist has not pick up that we don't have the heavy industrial infrastructure to build these sub in Australia years ago even to built the french Subs.
Great video, I feel the Collins got an unfair bad wrap by politicians and the media which used it as a tennis ball.
I mean, dont all new weapon systems have teething issues when first depoyed? Then these are ironed out over the months and years of the life of the fleet?
They had issues when they was first introduced to the RAN. But fixed many issues over the years. Sweden made more of these with new engines and different quieter propulsion system. New sonar computers and weapons system. I don't know why Australia didn't do the same. The ship yard for the collins class already exists in south Australia. They could had a entire new 12 fleet of upgraded collins class submarine by 2030 at a much cheaper price. And destroyed the older haul or donated them to NZ. Since they have no subs at all
i love this, i grew up down the road from where they were built and have even had the chance to be on board 2 of them
I was really looking forward to this. I already know it's gonna be a awesome vid 😁
The Collins class is based on the Gotland class predecessor the Västergötland class which entered service in the late 80's.
All four of which are still in service and have been fitted with AIP section two in the Swedish navy known as the Södermanland class and two boats in the Singapore Navy known as the Archer class.
Type numbers like 417 is the Kockums internal designation the Gotland was the A19 project and the Västergötland was the A17 project, i have a book i got as a kid with a flow chart of all the Kockums submarines but it's in a box somewhere sadly. The Current under construction swedish submarine the Blekinge class is the A26 project.
Swedish submarines always uses Swedish torpedoes and has done so since the 1930's, Swedish along with the Russian navy are the only two navies using hydrogen peroxide torpedoes (the kind of torpedo that sank the Kursk).
As an old Oberon Class Submariner, I commend your mini documentaries and find them very informative....[As a Plankowner of HMAS OTAMA, I wish to just point out the correct pronounciation of Her name.....It is pronounced O TAMA not OT ama.

This is in stark contrast to the reports in the media about the "dud subs".
A superior class submarine. I salute the Australia people for there ingenuity and intelligence
They are Swedish designed

"Stonefish" is an excellent name for a sea mine.
Yup. They're absolute bastards!!
I am impressed of your narrative skills and knowledge of Australian Naval vessels. Collins class submarines perhaps a little underrated since you gave an impressive rundown of their capabilities.
Very informative videos on ADF past/current/future Capability mate - fantastic work. Keep it coming.
Good video mate. Great to see someone making videos about these boats.
Do you have any other social media we can get you on?
@@enjays5026 TikTok mate I post every day
Fantastic video as always
Appreciate your informative video on this much maligned boat. To keep updating this Sub would seem to be the way to go.
Designed in the 70's built in the 90's, played 4 war games, couldn't find worker's to build them or submariners to sail them. Then had only 1 in the water at a time because of all the problems. At least the torpedoes worked,,,, 50 k range? How big are the Indian, Pacific and Antarctic Oceans again? Now the Australian Government wants to build 12 subs. Designed in the 90's to last till 2080 and it is now 2021 without a single piece of metal welded to another but it'll only cost 220 billion dollars. Here is the punchline, the "new" 90's design sub is nuclear powered but the Royal Australian Navy wants to put diesel electrics in them. Oh and these Collins class have to last until 2040 FFS GIVE UP ALREADY!
Wah wah wah

And I got the last laugh after all.
Should also mention that HMAS Dechaineux nearly sank in deep water off Perth in 2003. Would have been our own Thresher disaster.

There's something adorable about the Collins class subs.
16/06/2022 Thanks for the overview on the Collins class. You didn't mention the exercise around Hawaii where one of the subs "sank" major elements of the USN it was exercising with. I would really like to see a report on how much money we spent on the Attack class design, something which had been going on for some years; any research/design done during this time would now belong the the French (?). Lastly the ARKUS deal may see us getting a sub with a Astute class based design. Would you please do a comparison between the Virginia cless and the Astute. I understand that Astute have 20 or so less sailors on board which to me makes it the better value boat.
Fewer sailor = a better value boat? Because? Follow your logic to the absurd: no sailor’s aboard is the best value boat! With the advent of AI and drones, that might become true. 😂
All we have to do is upgrade this to Collins MK II.
We have all the knowledge, including the mistakes to build our own subs. With the amount of money they are willing to spend, we could include in the program a modern fuels solution. Be it hydro, thorium or just sticking with diesel, but an option to reto-fit later.
USA, UK, Russia, France and China have Nuclear submarines.
@@thehighlander959 India as well
@@thehighlander959 they all sport nukes as well. Bet you need that capability to.
Love your work! Let’s just keep the Collins class as well and change its Arsenal to adapt. This new barracuda could take way to long
re watching this I cant but wonder at a refitted Collins with new weapons control systems and new deisel gens + new Lion batteries and no periscope
The best of heard.lets build Collins MK2 as well as Collins class.Australian made and designed.
This kind of well laid out and step by step video might even work on the experts on naval warfare that comment on the latest rubbish posts by Skynews on the Collins.
Would like to hear your analysis on the decision to to buy Nuclear Submarines - which class would be ideal/capable specifically for our AO. Thanks.
Awesome vid, thanks!
Great video thanks. Wonder if the French ones will be as good, cheers.
Awesome content!
Very informative and concise.
Excellent.
So why not build more of these, in upgraded modern systems equipped versions inside these hull types, rather than start over with the barracuda design? In any case, and as always, fascinating🖖🏼
They look into that as part of the Competitive evaluation process.
The problem was capacity for expansion of future capability. The Collins was built with a capacity for upgrade. It will be tapped out by 2040.
To build in that room to grow, it was determined that a fresh design was better than modifying the Collins.
Evolved Collins was heavily looked into
Collins Class should be called Hero Class - they are all named for the greatest RAN heroes - and they have superhero like powers.
Great information as usual. Well done.
Always wondered why we didn't use the "Stirling" incorporated into our AIP.
Next please explain the Attack class propolsion system.
At first, Australia deemed it "unproven", so they went with normal diesel. Later, my bet it is pride/cost is the reason to not do it. Because, the Swedes proved that the Stirling AIP is indeed even quieter. They adopted in on Gotland, and now on Blekinge (A26). Both these subs make the Collins loud in comparison. But the Collins is still a beautifully designed submarine. They just need to be upgraded to 2020 standards.
Good content. Thanks for posting.
Read the Murdoch press, and you get a totally different impression.
Great job, I notice on the international space station all liquids are recycled into either air or water, even sweat. Might be an interesting project on a sub.
Should build another 6-8 updated models whilst we wait for to get screwed by our
✌️allies✌️ in the AUKUS deal….urgently
News flash !
We've now sunk the French contract, for the U.S.A. Virginia Class as of Sept 16 2021!.
I think AIP is more suitable to confined seas such as the Baltic. They give 2 weeks of submerged non snorkling lurking but at very low speeds. This is probably not worth it for Australia that operate in bigger spaces.
What will happen now with the new submarines?
HOW DOES AUSTRALIA KNOW THAT THEY HAVE ONE OF THE BEST SUBS IN THE WORLD?
Great video, recently found you channel and love the content. Looking forward to our national interests nuclear subs seem the best option from a capability and high tech manufacturing perspective. Do you have any thought in this regard?
Can you list a link about the “2 to 3 minutes to recharge”?
I did mate, its a pinned comment
@@hypohystericalhistory8133 it doesn't say it only takes "2 to 3 minutes to recharge", which isn't possible with today's best batteries (let alone the lead-acid batteries used on submarines).
The article DOES make the very dubious claim that it only needs to snort for 'less than a few minutes' in every 24 hours, but this is not the same thing. It makes the claim "Collins can recharge its batteries IN ABOUT ONE HOUR at a speed at which an Oberon would have little power reserve for electrical generation".
Desh-hay-no
Way more capable than I gave them credit for
The Soviet Tango class were as large, larger by displacement.
Could you do some more short videos like this on other platforms?
Yeah man, I’m thinking of doing a whole bunch. Any requests?
@@hypohystericalhistory8133 Patriot missiles and other ships and systems,you could probably make a thousand videos there’s so much to cover.
@@hypohystericalhistory8133 I was thinking you might do something with famous battles - Tobruk Kokoda Milne Coral etc etc. I think your unique approach would be interesting.
Loved this
Good thing they are good. Seems Australia will need to use them for a very long time. Might have even been better off buying 80 billion dollars worth more of them? oui oui
Great video. You need to follow this up with a video on the Attack class submarine? Is the scrutiny deserved, or is it overblown?
Thank you
Better get working on a video on the new nuclear sub options.
As a former submariner I find it odd the RAN is contracting with France for a non-nuclear version of an SSN. Versus going with the proven Japanese design offer.
I think it was just way more capable; soryu is a marginal improvement over Collins.
@@hypohystericalhistory8133 nah mate, Soryu offers ion lithium battery.
So,...will be Astute or Virginia Class for the Royal Australian Navy? And what will the expensive upgrades bring to the Collins Fleet? Big couple of days.
I think the UK is junior partner here, they may help train the Australians after they've finished the building HMS Agincourt. Virginia class is more expensive than the Astute Class but I believe the US will have to subsidize the Australians in exchange for basing nuclear submarines. Personally believe the Australians could get there hands on some old Los Angeles Class and Trafalgar class submarines. The Trafalgar Class is younger than the Los Angeles Class but require few crew members. US submarines are larger and require more crew and more expensive to build, maintain but the latest block V Virginia classes can carry more torpedoes and tomahawk.
Really depends on Australia's ability to finance, crew the submarines, who have more stringent requirements and if they are getting subsidised by the US. The US will send over some technicians but that might detract from the construction of their own production of Virginia classes.
If Australia gets the Trafalgar Class submarine whilst HMS Agincourt has finished it's going to rub the French the wrong way. You don't want to remind the French of their catastrophic defeats. But then again the French cheated Australia once they were selected and increased the price and amount of components that were to be sourced from France.
Makes you wonder why an evolved Collins class wasn’t developed instead of the French boat which is causing so much controversy
THAT!!! is a very good question.
I still don't understand why there was such an insistence for the French to build our next submarines? The controversy even before they start is enough to realise that once again, the Government meddling is going to cost the taxpayers billions in cost overruns; that is if they ever start.
Great stuff
I know that two of this subs, are been offer to Chile,s navy, it is that true ?
Love this!
I never knew how little time they had to spend at the surface recharging, and I've read a lot about them! Great statistic- helps explain why they're so stealthy.
Scrap Barracuda class and produce Astute Class. RAN personnel can then train with RN Astute crews prior to having Australia's own Astute fleet. Australian based Astute service/repair facility allows the RAN and RN to work closely together. The UK needs a Far East Base and a combined Naval and Amphibious Facility with an Airbase would allow flexibility for Combined Operations. This would also attract the US Marine Corps for multinational Exercises/Training. Italy has a Strong Navy/Amphibious set up and I am sure would be grateful to be able to operate across the globe. Think Big, Think Friends, Think Power Projection.
That makes really good sense
Can you do a video on an Australian fleet compared to a Chinese carrier strike group
the two shall never meet. The Airforce and Submarines would nail any fleet coming toward Australia.
No point they are our biggest trading partner why fight your best customer 😅
@@nathand7560 because china have been acting like arseholes towards australia and trying to intimidate us with trade. They have been unreasonable turning ships away full of livestock and crap.
@@nathand7560 and not to mention they are attempting to claim the whole south china sea, but why stop there? why not build some islands in the pacific and claim that?
@@redherring6154 I'm not saying China is perfect but they are no worse than the USA. The yanks don't even need to build islands to claim territory, they just swap the leader of a nation for a puppet and build their military bases all over the place. The only reason China is flexing on us is because we are seen as the American lap dog in the region, if we traded with them peacefully and got out of American wars we wouldn't need to spend billions on defence against our trading partners.

Three minutes is long enough to get spotted. And I don’t believe a three minute charge lasts 24 hours using relatively OLD tech. 😮
Can you do a guide to the super hornet?
I think the new technology in the battery systems today gave the collins class a greater capability.
Best diesel sub?
Not getting the barracuda getting the Virginias or Astutes (nukes)
I saw report years and years ago that thw Collins Class subs were like "underwater discos", then I read they went to the US for noise mitigation
There were initial problems with noise but alterations to the stern, I think, as well as some other changes removed the problems. Having spoken with people who have served on a Collins class sub, he confirmed that they are very quiet and among the quietest of current subs.
I'd heard the problem was with the propeller and it took a few years but they got it right in the end.
Rumour I heard was that the ‘underwater disco’ comments were based on tests done without the anechoic tiles fitted. A bit of political manoeuvring between the major parties in Canberra. Trying to embarrass the govt by shitting on defense?
@@psychalogy either party does that, when in opposition
They asked an engineer in Australia to look at the noise problem with the Collins and solved it by fitting a hump forward of the conning tower . If I remember correctly it's fibreglass but I could be wrong on that part .
At the 2:19 mark you said that the Collins Class only has to charge for 2-3 minutes every 24hrs. I don't know where you got your information from but that is 🐂💩.
AIP was never tested on the Collins Class. It was investigated and there was talk that it could be a future modification, but to do that would mean cutting the pressure hull adding an extension unit just behind the fin. They option was later cancelled as it would have had an effect on the hulls life. Yet again, your information is wrong
Love your videos!
Incredibly minor nitpick but the letter H is pronounced "aich", not "haich"...
"Kick his ass SeaBass"
Love your work, just found you. I'm amazed to hear such a positive report on the Collins class. I was always led to believe it was a piece of shit with old technology n useless in modern world. I also heard it was always broken down but that turned out to be true. Good to know
Nah mate they are absolute beasts; just like the F-35 they had problems early, but now they are world class. Really, only the Japanese Soryu class are comparable in terms of conventional submarines.
@@hypohystericalhistory8133 new favourite channel, currently chewing thru your 2 hour ask me anything vid.
@@donmacdonald8516 The Collins class only had a few issues as they were being over worked mate 😀.. with only 6 subs we should only been using them for training/ upgrades only .. if we really wanted to deploy subs on mission's we really needed another 6 subs ! RAN did an amazing job considering we only had 6 .. When Australia had war games with America one of subs sunk an American aircraft carrier , RAN definitely got the most out of our subs ,
Looks like we are going to upgrade our 6 Collin class subs so that should make them match it with most subs in the world .. just wish we got 12 so we could see the sub at its full potential ..
The end of the video will have French viewers breaking down. They are pissy because they thought they could take as much money from Australia as they wanted for 50+ years but the aussies told them to jog on. A rare sensible decision from governments
SWEDEN SHOULD HAVE CONSULTED ITS POLICE FORCE ABOUT BUILDING SUBMARINES.
The Aussie need Nuclear boats now. Cancel the French contract now and buy a few Virginia class boats.
No we don't,
Nuclear is old tactics ,
asuming you can just by americas weapons like that, they dont give 2 fucks about us.
@@jasoar1563 Believe me, they do now. USA, BRITS and FRENCH build very good Nuclear boats. The boat Australia purchased. is normally nuclear powered.
Mate even if we agree that we need Virginia class, the yanks would have to agree to sell them to us and they are busy build them for their own navy.
@@thehighlander959 Incorrect and has been clarified and debunked by Government, Defence and the builders, we are not converting nuclear submarines to Conventional, we are designing and building a clean sheet design !
The Collin class seem pretty decent let's hope the French don't screw it up, like the Spanish did with their submarine program.
Building your own submarine program from scratch is something very hard and difficult. Problems and difficulties always come across. If you think that only happens to spanish ask british, american or french builders how difficult it is and which problems have had in their own programs.
And the spanish have succeded in creating their own submarine, capable and with an autonomy never seen before in any conventional submarine. They are not nuclear (with almost endless autonomy) but almost.
@@jesusalvarez-cedron6581 yeah but at what cost, they should of kept collaborating with the French. The technology isn't fully mature, they have no tomahawks and had to curb military spending elsewhere. They also need to retrofit there new subs at some point, that's going to be quite costly, but they needed something to show for and decide to commission it prematurely.
@@MegaMrWrong I agree with you, but the french won a bid to build conventional submarines (what the australian gov. wanted). If I'm not mistaken the french submarine in its original form is nuclear powered and I think there are some of them already active in the french navy.
I mean, i think that apart from loosing that BIG contract after investing in it millions of euros, they see that the australian goverment what they really want is a nuclear powered submarine (¿?) from USA.
I'm not french but I understand them. I think that inconsistency from the australian goverment is not good for themselves, as France is an ally (I know that not as close as USA). They have been rude and abrupt in their forms.
But, if someone ask me, Australia is doing OK closing ties with USA. But they shouldn't have done the deal with the french from the start.
@@jesusalvarez-cedron6581 to be honest I think the French should of been more open and frank with the Australians and not over promise and under deliver. They were sort of dragging their feets with the design whilst they were figuring things out with their own Barracuda subs.
I think America needs nuclear basing in Australia and want the Australian to bring forward their capabilities quickly to counter China at a much more faster pace than the French are comfortable with. The French may want to just delay to project abit to maintain their skillset, but now I think they will have a gap in production. Whilst I do not really know why the British are involved but they do need to maintain their skilled work force after HMS Agincourt is built, it started construction back in 2018. They may just be sent to Australia to train up the Australians whilst American carries on building their own Virginia class at full speed. Weird that the UK just announced that the successor of Astute Class is underway 2 days after the AUKUS.
They had all sorts of design problems and we're not all operational until approximately 2016
I think your statement regarding snorting if wrong. No submarine can top up their battery in 2 minutes unless it is already at a high percentage. The speed of the submarine determines how low it will be and how long it needs to be charged for. The collins charges about 4 times as quick as the oberons
Exactly. The OP clearly didn't understand his own link.
The article DOES make the very dubious claim that it only needs to snort for 'less than a few minutes' in every 24 hours, but this is not the same thing. It makes the claim "Collins can recharge its batteries IN ABOUT ONE HOUR at a speed at which an Oberon would have little power reserve for electrical generation".
breaking news from ABC news; Australia to quit troubled french sub, and go Nuclear subs via US/ UK.
Apparently not French replacements anymore ...
Use nuclear batteries reducing the diesel noice level . Using nuclear batteries last longer and do not need to recharge for 20000 years and easy to shield against the bata radiation. You will also have the quietest submarines in the world with no need
No need to cool the reactor with pumps when using nuclear batteries.

Collins may will get plenty of actual kills sooner or later.
In WW2 75% of all German Uboat crews died. In 1944 USN used a homing torpedo to sink the submerged Japanese submarine I-52 near France. Submarines have never been and never will be safe. They have some utility in peacetime but none after the first few months of WW3.
The RAN have difficulties in crewing the existing Collins class. Cancel the French sub order and participate in developing remotely controlled unmanned submarines. Traditional submarines are now the equivalent of a battleship in WW2 .
Utter nonsense. No military platform is safe; your argument here amounts to “infantry is obsolete because Hiram Maxim invented the machine gun. Cancel the Australian army.” Idiocy plain and simple.
@@hypohystericalhistory8133 And a huge amount of cherry-picking too. USN and Allied submarine attacks crippled the Japanese merchant fleets during WWII and starved their war effort. With the initial attacks from the Kido Butai taking out so many capital ships, it fell to the fleet boats and their contemporaries to take the fight to the enemy. And from day one, the bubbleheads were tenacious. Control/Denial of SLOCs is much easier with a platform that can be invisible and strike without warning, MPA notwithstanding.
Sweden upgraded there collins class submarine with a entire new engine and propulsion system. Australia could had did the same and built 12 new haul of them with new weapons system and new sonar system. We could had all 12 new collins by 2030. It would been cheaper too. We could of donated the older 6 to NZ since they have no subs
Why should we donate subs to NZ? Their socialist PM (and her leftist predecessors) made the deliberate decision to NOT invest in their own country's protection, and they can reap the consequences.
