Barracuda & Condor Projects / Titanium nuclear-powered attack submarines / Sierra I & Sierra II 

Easily one of the best episodes ever on Combat Approved, awesome job!

I miss Egorov's voice :(

I cant stop wondering if i had been in submarine, how many times i would have hit my head with some metal. Hats offs to the submariners all over.

I love these programs about submarines!!! Make many more and talking about the galley and how they prepare the food and desserts

Masterpiece

Incredible material science achievement building a titanium submarine . Russian machine Design is the best .

I did a paper in school on Russian technical prowess and their ability to do all kinds of incredible shit with titanium. I guess you develop the expertise when you are sitting on 98% of the planets titanium reserves. Their skill at welding titanium is second to none! I believe that the Russians also developed a method of spinning titanium like a spider spins a web. The information is alluded to but as an American, it was very difficult to obtain any tangible technical references pertaining to the art.

Russians know how to make the best weapons

The same Narrator doing different voices for each person just _makes_ this doc!

люблю твои серии любовь из Индии

❤ from 🇮🇳

These boats are surely marvels of engineering. The production of the hulls was literally breathtaking in boat sized purge gas chambers that the welders needed breathing apparatus in. And then they made them noisy and deaf compared to their western counterparts. Although the sierras became much better than before.

5:06 Lol, is it me, or is the english narrator´s voice of that officer just the same guy making a deeper voice?? That was funny as shit! Narrator: "Do you only have titanium subs?" Deep guttural voice: "NOO!"

Impressive Sub. Impressive video

The Varangian descendants honor their ancestors, forging titanium as weapons. Crush the enemies of Rus! Slava Rossiya

voices in this video are deeper than the diving depth of these subs

SLAVA RUSIJE SVAKA ČAST VELIKI ISKRENI POZDRAV OD SRCA ISKRENO SVIM RUSIMA

Loved the welding techniques be great to be a young welder again and working on Submarines in Russia. Being a Sub mariner wouldn't be for me bit of a land lubber All these men all over the world are very brave.

Excelente 🇷🇺💪💪💪💪💪💪💪💪💪💪💪

Fascinating stuff!

Смотрите, я немец. Я отслужил свою справедливую долю военной службы. Я никогда не испытывал плохих чувств к России. Не такая уж и редкость, кстати. так что политика в сторону. Мне очень нравится шоу, и я вижу, какие технологии вы, ребята, придумываете. Я просто чувствую, что времена очевидной пропаганды давно прошли. Все делают небольшую рекламу. Это нормально. Но, пожалуйста... ради бога, уменьшите этот отвратительный очевидный изгиб. И я так понимаю, родная версия предназначена для информирования широкого круга россиян о могучей армии. Но дайте нам хотя бы несколько нормально звучащий переводчик. Знаете, это не боевик :) в остальном... хорошая работа, и я с нетерпением жду того, что будет дальше. Не уверен, что пропустил, но есть ли эпизод с крейсером класса "Киров"? Было бы неплохо узнать больше об этом бегемоте. Я почти уверен, что русский перевод вообще не имеет смысла. Дайте мне знать, если я кого-то оскорбил. Это не было моим намерением ;) See, I am German. I did my fair share of military service. I never felt any bad feelings towards Russia. Not that uncommon btw. so politics aside. I do love the show and see what tech you guys come up with. I just feel like the days of obvious propaganda is long gone. Everybody does a little advertisement. That's fine. But please.... for the love of god, tune down this cringy obvious flexing. And I get it that the native version is to inform the broad range of Russian people about the mighty military. But at least give us a somewhat normal sounding translator. It's not an action film you know :) other than that... good job, and I am looking forward what's next. Not sure if I missed it but is there an episode with the Kirov class cruiser? Would be dope to learn more about that behemoth. I am pretty sure the Russian translation doesn't make sense at all. Let me know if I insulted anybody. Wasn't my intention ;)

Great afforts have been made for the dubbing less "cartoonish", but as a russian learner, i prefered the subtitled episodes.. Anyway, great increase in quality !

It's without doubt, the Russian Federation Navy are the Kings of the oceans. Stay strong and keep building larger and better. The submarines show here are definitely a work of Highly Technical art. 🇷🇺👍

With a Titanium hull, this sub can dive deeper than her steel counterparts

As the presenter of this series of Russian military documentaries called "Combat approved", how can you be surprised by how much security there is around a nuclear powered, nuclear capable submarine base holding nuclear ICBM's.

Excellent video, captain.

knots actually comes from when they had a rope with knots in it that they let out over an amount of time to determine speed how many knots they where going.

Russia builds awesome submarines!!!

So much sea growth on those boats that they apparently are re-named "Pier One" and "Pier Two". Like a Tank that ran out of fuel.

Awesome, I love these COMBAT APPROVED videos, Russia has some awesome equipment that seems to be built to last, not stop working after the next system update "keep it simple stupid".

Lovely episode 😄

Please can you bring back original Combat Approved with english sub? I like original english subbed than english dubbed

titanium is probably harder to find with a magnetic field disrupter system.

Love you mother Russia love from Jamaica be strong for us we need you to be strong

We MUST WORK TOGETHER TO MAKE THIS WORLD A SAFER PLACE 🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸

I´d love it Combat Approved dedicate a episode to Project 941 "Typhoon".........

Great Uploads. Defendd Yourself and preserve the peace too.

They are AMAZING!!

very good job

More of these new episodes! I get these recommended on the russian zvezda channel but I don’t understand russian😭

Well the world knows now, and I had a feeling this was going to be the best submarine in the world, you hear that on every episode, but love watching this to see the engineering Russia comes up.

Titanium submarines I will always love. I would love for it to serve 100 years, then other countries would build them too and we could have more amazing boats. I also have a lot of respect for how much development and success Russia has had with escape capsules in their submarines ever since their tragic past.

Awesome engineering! 🇺🇸

That is the most impressive documentary I've ever seen....ever. very best wishes and support to Russia from Ireland, truly amazing 👏👏👏👏👏👏

I genuinely love this type of submarines it is a shame that they stopped modernising and refitting the Sierra A, I genuinely believe it can out perfume submarines like the los angelelese class or even the severmanosk by just getting a new propeller, thicker newer coating and modifying electronics.But then again the Akula is having the same problems, its sad, Russian/soviet Technology is so different from western doctrine and they can honestly out perfume them if just upgraded. Like instead of Russia building improved kilo class all the time and the Lada class they can just refit and upgrade these.

Solid as Titanium. Combat Approved to protect Mother Russia.

There is no rust but there's a water leak at 8:15 the floor is all wet. At 8:23-8:28 you could see the dripping of water

How can a man build this thing 🤔 my Goodness, engineering is different

War sucks, but these toys are amazing.

Why is this unprecedented when the Soviets built Project 705 Lira (NATO name Alfa) out of titanium more than 50 years ago?

Simply amazing...😳

Fantastic channel

Russian submarine interiors would make a good setting for backrooms style games since everything looks yellow.

Russia needs to build titanium tanks!

amazing military documentary

An excellent programme. 👍👍

Impressive boat, looking a bit dated and old fashioned though. Imagine its costly to fix and maintain and building new is best value.

Russia needs to reconsider it's export controls on Titanium. Especially to their adversaries.

Thanks for letting everybody know these subs are sealed in rubber, good to know.

The captain's diagonal seating reminds me of the bridge design concept of the original series of Star Trek where the bridge is offset diagonally to the direction of travel which caused a lot of confusion among Star Trek fans. I suppose when you command a submarine it does not matter which direction you face on the bridge since there is no outside view to look at.

And it will dive into deep sea without any problem or fear of disappearance. Hats off to the Russian engineers..

Awesome

he really loves the fish eye lens

whoa the have a pocket size depth charge against saboteurs

No constipated voice!!!!

Its good Russia is opening up to the world through these documentary series. Very educative

and Titanium was in the air frame of the SR-71 ;) bought directly from then used to watch .

thats something that scifi movies forget when your ship is made from indestructible material's then how do you shape them when any kind of high energy weapons cant bend or break them then how are they shaped into a ship?

The footage of the subtail with a year of marine growth, doesnt say readiness and maintenance.

Really nice submarine class. Sadly only 2 operational out of the original 4 and only titanium hulled submarine's left in the Russian navy, if you don't included unarmed ones like the Losharik. Steel hulled won out in the end when these competed with the Project 971s. One of the factors was the 971 could be built wider as Titanium assembly docks were too narrow and costly to widen thus allowing it to have a bigger and more modern bow sonar array. While the Project 945As fixed this by removing the bigger diameters tubes and having 6x533mm instead of the 8 4x533mm by 4x650mm tubes of the Project 945. Hence why the navy really just wants to keep their more modern Project 945A's in the navy. At the cost of these submarines and the difficulty in making wider and more desired hulls, it's doubtful any more submarines of this size will ever be constructed by Russia. The last of their kind. Interestingly enough the submarine's original screw was a 6 bladed titanium propeller (You can find photos of it, it's really cool), though we can see this has been changed to a quieter 7 bladed skewback propeller in the model on the desk at 12:28. I wonder if this is also titanium. I know most brass propellers use sacrificial plates welded to the hull. Is this not possible with a titanium ship or did they just want to go to the effort of making the submarine as light as possible. The cost must have been enormous for such little savings if so. This was a great video going into the process of welding, talking about galvanic corrosion and so many more interesting things most people don't know about the hardships of working with these metals.

Magnificent!

Hope Philippines will prioritize Russian Subs and ship in the Navy

All the metal here is TITANIUM! 😀😁

Wow, i can see the barnacles looked like amazonian forest...

Drinking game : Every-time they say titanium, you drink ! Even Russians would get drunk..

Wow👍

More episodes of submarines !!!!

I think I forgot what material is used...

I wanna see Sub Brief do a video on this

Russia makes the best Sub's, I don't buy NATO BS that Russia subs are noisey, Russia has always made great subs from the Alfa, to the puppa in the 60s, okay they were noisy, but stealth isn't everything, as being able to dive deep and fast is just as important for a sub survival. The Sierra class sub is a unique sub that can dive over 4000ft, which is three time deeper then any NATO sub, also they are just as quite as a second class 688 attack submarine.

She looks nice I wish my nation have one of this rather than the second hand chinese copy of Kilo class😩

How many them say-Titanium-

Two reactors, twice as much chance of radiation exposure.

Awesome episode .

Is a video on the Belgorod coming soon?😅

Calm seas and a fair wind at your backs. Salomè (live in Peace), und… Mögest Du in das Licht, der Wahrheit, und dem SEIN der Schöpfung leben.

The Daniil Moskovsky was suposed to be scrapped in 2021, gess not.

Tungsten: how about me?😔 Im stronger than Titanium

It’s funny how these sailors keep saying, look how clean it is inside with no rust. To me that means the regular Russian sub leaks badly. I will guarantee that no American subs leak.

It will last longer if you keep up the rubber skin... And if you use shark rubber skin it will go even faster..

Keren bro 👍🇮🇩

Even their new military equipment looks old. Russian armed forces are laudable

Its weird by my leach dream wouldn't work here.

URAA!

Titanium ❣️

My predictions is right

NATO MEMBERS-Our hyper cars exhaust is made of titanium RUSSIA- Our submarine and SU57 is made of titanium🤣🤣🤣

Why are the subs covered in seaweed and barnacles. My sailboat hull is alot cleaner. Looks like they don't do basic maintenance

Great episode, but they look like they haven't moved in years, judging by the build up of mess under the surface
