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.

This is a right proper video about Collins-class submarine. VERY Well Done hypohystericalhistory.

I was really looking forward to this. I already know it's gonna be a awesome vid 😁

Great video, I feel the Collins got an unfair bad wrap by politicians and the media which used it as a tennis ball.

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.

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

Very informative videos on ADF past/current/future Capability mate - fantastic work. Keep it coming.

Awesome video as always, thanks!

Appreciate your work man hopefully your channel grows 👍

Awesome vid, thank you for the time and effort that you have put into this and the other vids, I have subscribed.

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. [Bye the bye, OTAMA is a Queensland Aboriginal word which means Dolphin] Yours Aye Rick Fishbourne.

Good work mate! Good video and nice length 👌

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.

Awesome content! Very informative and concise.

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).

Ranken is a beast, playing their "victory song" if you know what I mean

Fantastic video as always

Good content. Thanks for posting.

Awesome vid, thanks!

"Stonefish" is an excellent name for a sea mine.

Good video mate. Great to see someone making videos about these boats.

Hey man love your stuff you should upload it to Spotify and Apple music

Appreciate your informative video on this much maligned boat. To keep updating this Sub would seem to be the way to go.

Loved this

Excellent.

This is in stark contrast to the reports in the media about the "dud subs".

Great stuff

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?

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.

Love this!

Thank you

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

A superior class submarine. I salute the Australia people for there ingenuity and intelligence

Should also mention that HMAS Dechaineux nearly sank in deep water off Perth in 2003. Would have been our own Thresher disaster.

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.

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.

Great video thanks. Wonder if the French ones will be as good, cheers.

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.

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.

Great video. You need to follow this up with a video on the Attack class submarine? Is the scrutiny deserved, or is it overblown?

Can you list a link about the “2 to 3 minutes to recharge”?

The description sounds very interesting, but before I watch the video I had better read through the comments to ensure that this content has been properly vetted and approved by the KZfaq Experts. :)

Can someone explain why we haven't just been iterating on these subs rather than looking to buy from overseas?

Could you do some more short videos like this on other platforms?

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🖖🏼

There's something adorable about the Collins class subs.

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.

NZ needs 2 of these

The best of heard.lets build Collins MK2 as well as Collins class.Australian made and designed.

What will happen now with the new submarines?

Desh-hay-no

I know that two of this subs, are been offer to Chile,s navy, it is that true ?

News flash ! We've now sunk the French contract, for the U.S.A. Virginia Class as of Sept 16 2021!.

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

Best diesel sub?

Can you do a guide to the super hornet?

Collins Class should be called Hero Class - they are all named for the greatest RAN heroes - and they have superhero like powers.

Can you do a video on an Australian fleet compared to a Chinese carrier strike group

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

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!

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.

Better get working on a video on the new nuclear sub options.

Read the Murdoch press, and you get a totally different impression.

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.

Makes you wonder why an evolved Collins class wasn’t developed instead of the French boat which is causing so much controversy

Should build another 6-8 updated models whilst we wait for to get screwed by our ✌️allies✌️ in the AUKUS deal….urgently

HOW DOES AUSTRALIA KNOW THAT THEY HAVE ONE OF THE BEST SUBS IN THE WORLD?

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 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

The Soviet Tango class were as large, larger by displacement.

Love your videos! Incredibly minor nitpick but the letter H is pronounced "aich", not "haich"...

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.

Way more capable than I gave them credit for

I think the new technology in the battery systems today gave the collins class a greater capability.

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

Not getting the barracuda getting the Virginias or Astutes (nukes)

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

Parliamentary committee? Was that the committee featuring Pauline Hanson? Ok cool, I'm so relieved now that Australia's navy is in good hands... *facepalm*

Three minutes is long enough to get spotted. And I don’t believe a three minute charge lasts 24 hours using relatively OLD tech. 😮

The Collin class seem pretty decent let's hope the French don't screw it up, like the Spanish did with their submarine program.

"Kick his ass SeaBass"

This is why Volvo doesn't made diesel engines.

if they can not man 6 boats how are they going to man 12 ?

"The Barra's are Yarra's"

breaking news from ABC news; Australia to quit troubled french sub, and go Nuclear subs via US/ UK.

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.

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

Apparently not French replacements anymore ...

Collins may will get plenty of actual kills sooner or later.

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.

Meanwhile in nz 😑

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

They will need them because their New subs won t come anytime soon!

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 .

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

My brother in-law was in charge of theses he said that they are crap shit always breaking down and on and on problem after problems with them the new ones are no better I’ve been told

Snort for two to three minutes every 24 hours. Hmmmmm

Snorkel thermal exhaust plume immediately detectable by low orbit satellites
