My former brother in law was part of that crew of this Sub. Its been DECADES since my sister divorced him but he was only about 5'4 tall but a great athlete. The tests he took to be part of the crew was no joke from what he told me of this one particular mock event of the Sub flooding while trying to fix the leak of a cramp low area. He said he simply stay calmed and held his breathe until the bubbles come out as I assume a sign to lower the water. Most of the crew are short.

[@ButchNews]

Navy basic training involves sailors in a mock up flooding ship with water coming in EVERYWHERE... by the time you get it stopped you are waist deep in water.

[@nunyabidness976]

@@ButchNews When did that start? Closest I came to water, other than PT in the rain, was the 90 ft jump.

[@ButchNews]

Yup... part of the training is a special mock up sub that is flooding, and filling with water and you have to try to stop it. They don't let you drown. Also, you have to surface in a special tower 100 feet tall full of water on a breath of air you take before exiting that room. If you aren't blowing bubbles, divers are standing by and will punch you in the stomach to make you expel air so your lungs don't explode.

The GOOD NEWS about submarines is they have way more HEAD room than ships because all the pipes and wires go down the sides, not in overhead passageways. Short guys are quite useful in Special Ops. Me, I'm 6'2" and served in three subs.

VLF (Very Low Frequency) communications uses LONG wavelengths, NOT Short.

[@craigcooknf]

So, the buoy mentioned carries out a wire a distance basically equivalent to the wavelength of the signal?

[@willowsloughdx]

@@craigcooknf No. A small portion of the VLF wavelength will work for receiving. VLF is used for one-way communication only: reception by the submarine. VLF wavelengths are so long that transmitting VLF from a sub is not possible, nor do submarines have the high radio transmitting power necessary for VLF. Also, transmitting a VLF radio signal from a sub could give its position away.

Ohio class never had anechoic tiles. When this class was introduced, USA did not have this technology and when they received that from British, unlike on american SSNs, they never installed them on their SSBNs. I did not figured why. My theory is, that these tiles are effective against active sonar during fight and Ohio should never get itself into fight. And when you do not need to damp active sonar then anechoic tiles are burden (because if they peel off, they increase passive sound emission of submarine). VLF is one direction communication. From land to submarine. Submarine lacks antenna capable to transmit on that frequency. Sonar is used in active mode only in specific situation, like in battle. Otherwise active sonar always reveal position of submarine. Ohio class really do not use Mk54 torpedoes. No american submarine does. It will need special adapter to be able to fire 324mm torpedo from 533mm torpedo tube. Tomahawk with conventional warhead does not have range 2500 km. Roughly half of that value is correct. Higher value is for nuclear warhead, which weights 1/3rd of conventional one and spared room is replaced by fuel. PDX-57 does not store 2,6MW of energy, it would be just 722 Wh and this will be extremely poor energy density even for lead-acid battery. In fact, they store more than 10 kA-hours at 2.0V of nominal voltage, so at least 20 000 Wh at weigh roughly 953 kg it is energy density 21 Wh/kg, which is not bad for Pb battery but also not great (for example Kilo class is using Pb batteries with energy densities from 37 Wh/kg at rapid discharge to 52 Wh/kg at slow discharge). Whole Ohio class batteries capacity is 2,6 MWh (it has 130 PDX-57 cells which are producing via inverters stable 240VAC and 155VDC used on american submarines). Although I admire your 3D animation capabilities, I have to say, that layout and cutaway is more your imagination than reality.

Nice video. But a misconception about buoyancy. The main ballast tanks (MBT) are all at the forward and aft ends of the hull. Interior tanks are within the pressure hull are for trim purposes only. When the main ballast tanks are vented to sea (filled with water), the submarine attains neutral buoyancy, not negative buoyancy. The MBTs are never left partially empty - - they're either full of air for surface, or completely vented (filled with water) for submerged. As for negative buoyancy: That is something not desired, because if propulsion is lost, you sink. If anything, it's better to have very slight (very, very slight) positive buoyancy while submerged, and rely on the dive planes and forward momentum (speed) to keep the sub at the desired depth, even if just a few knots. Enlisted berthing: This is on the 3rd level (not second), on the same level as the galley (dining) and heads (restrooms). There's only one diesel generator, not two. There's also the lower section of rudder which is not shown.

Around 16:40, the batteries are said to deliver so many watts of energy. Strictly speaking, watts is a unit of power (energy/time), not energy. Also its a bit odd to express battery power, unless the duration of time over which that power is delivered is stated (i.e., total energy = power x total time delivered)

[@SCGATOR2001]

My solar battery setup uses so many batteries and each one is limited to100 amps. Knowing the volts, I can figure out the max power delivery by the LiPO4 batteries. But the real delivery limit is my inverter. Back on the old (now ancient by comparison) submarine we used MOTOR GENERATOR sets that delivered AC power which would power the Reactor Coolant Pumps etc. But as you pointed out, that has nothing to do with HOW LONG the batteries can supply that amount of power. You can get an idea of how long that is by making an estimate of the volume of the batteries that is possible and that will lead to HOW LONG they can power the essential loads needed. In most scenarios, the real limit is how long you need to get to PD (periscope depth) so you get a DG started. That will be the real op limit before you need to get the reactor restarted but on the old boat, the DG fuel tank was used as shielding for the reactor and that had plenty of fuel for a lot of hours. Running the DG at periscope depth or on the surface out in the open ocean is no fun as big waves close the intake when it goes underwater at PD and on the surface? Well it doesn't take long for even the 20 year vet chiefs to get sea sick as they aren't used to it either. The goal is to get the reactor restarted and get back to depth where everybody can relax.... I remember in the N Atlantic with a typical winter storm, huge waves sitting at PD getting beat up. One of the EOOWs took a simple instrument failure and screwed it up into a reactor trip. I'd give him shit even today for his screwup because I remember that night very well. I was new RC (reactor controls) div officer and that was frequently a first job for new officers.

[@johannjohann6523]

Amps would have been the correct term to describe the energy available? As an accountant by trade, but have recently gotten interested into working on my own cars (since its so hard to find an honest mechanic you can afford these days) I've started delving into both the electrical systems of cars, and even stereo components. Electricity is pretty weird and so often taken for granted it's been interesting to learn how both AC and DC work. That almost everything that creates electricity (ex. alternator, computer) make AC current and then a rectifier is used to change it to DC. And how everything Tesla invented back in the 1880's is still being used today for power generation with little change to his design. What a brilliant mind. But I've Learned quite often its only a few dollars part that cause either your car or stereo to malfunction. It's just finding that cheap and often made in China part that is the challenge. lol. thanks for the comment. I just hate the idea of tossing something out when with a little effort you can cheaply fix it yourself, not add to the landfills, and save ya $$ to boot. take care.

When I was a kid, I built a toy sub out of plastic foam, put in a fair amount of led snots for ballast and tried to achieve neutral buoyancy by adding very tiny chunks of led wire. I wanted to see my sub soared in the depth of my bath. It never happened. Floating sub always sunk .Neutral buoyancy is quite unstable state, could not be set for a more or less long time. The better accuracy of the math - the less speed sub needs to maintain “neutral”buoyancy.

From the design stage in the early 70's, to its launch in the early 80's, it was a very impressive machine but that was 50 years ago when computer technology was in its infancy.

An era of global surveillance, satellite networks robotics and most of all, artificial intelligence that will allow for un-manned, coordinated, swarm attacks and that's just the beginning. The carrier task force and the fighter jets it carries are obsolete as it the 50 year old SR-77. The Chinese already have their own JPS network giving them the ability to locate anything on the globe perhaps even underwater. The Big Boys in arms development are already showing up in Washington with plans to counter these threats but as with EV cars, we can't compete. Chinese graduates 6 million engineering degrees per year and the US 80k and half of them are Asian students studying in the US.

crews berthing is on the third level, not second level of the missile compartment. MM1/SS USN retired here.

Can you confirm, that you did hotracking on Ohio class?

[@dannywilliamson3340]

@@tomascernak6112 No, but the raquetball court wasn't full regulation size.

[@elbryan9]

@@tomascernak6112 Hot racking isn't the norm on tridents but on occasion it does happen. We had riders one patrol and a couple of the FNGs had to do a little hot racking. Thankfully (for them), the riders weren't aboard the whole patrol.

[@samfisher2306]

Very informative. Frightening how the Trident II can carry 12 to 14 nuclear warheads. It looks like there could be at least 12 of them on one sub. That's insane firepower 😅

[@sygdesignworks]

Did you know that a single Ohio class submarine carries 87 Megatons of firepower! It can completely Obliterate 336 Cites! Thanks for watching!

[@samfisher2306]

@sygdesignworks 87 megatons is nuts. I think submarines are the scariest weapons right behind nukes because they're everywhere & nowhere. Silent assasins!

[@FLY2KO]

182 independently targetable warheads per boat, I was on one.

[@AzrealMaximus]

If any of these subs launch their tridents, it's well past game over. Either the MM2 and bombers on alert got caught in the silos or at their bases, or not enough FAFO nukes survived post launch. Either way, it's back to the stone age.

[@DrewLSsix]

​@user-yq3fz9ch5q nah, the nuclear apocalypse is absolutely over blown. The scary part people want to avoid thinking about is that a nuclear war will absolutely fuck shit up, but it won't reboot society, many many of us will survive along with a battered infrastructure, the ugly truth is we will probably live and have to deal with the literal and figurative fallout.

[@Ilike-bear]

Were interesting material.

[@casualsleepingdragon8501]

Fun fact: the sonar is loud enough to kill a person in close range

[@EricThompson1965]

Ohio class submarines with the BQQ-6 Sonar system don't even have active sonar. All we had was an under ice transmitter for pinging ice above us. Tridents don't engage in ASW. We ran from all threats to remain hidden to end the world

[@EricThompson1965]

Tridents have no active sonar

[@chris47374]

Genuis!!!

[@sygdesignworks]

Thanks for watching!

[@sotm6078]

Point of correction The steam when cooled back to water does NOT return to the reactor (That water is a closed system that is highly radioactive) it returns to the steam generator where is will be heated to steam again and again.

[@elbryan9]

I was a nuke electrician from 98 to 09 and after seeing all the mistakes he made up in the cone I was like, welp, the engine room sure ought to be interesting! lol Can't really hold it against him too much though, considering just how much more difficult it is for outsiders and civvies to get accurate info.

[@spiffymagicman7284]

Im planning on stealing one of these subs soon😅 thanks for the lesson!

[@Mikemonoa-hz2rz]

I love how the torpedoes play cat and mouse lol 😅😂

[@Cad1s]

Very nice the only problem is the information about the sonar, Submarines use two types Active and Passive You described their active sonar quite well but its not used all the time or hardly at all as it gives away your position to the enemy as well as tells you where it is. Passive sonar is using both the ships hull mounted hydrophones as well as the towed array which is a cable the sub will drop behind itself and is covered in hydrophones allowing the ship to listen behind its screw as well as grants the sub a better idea about what is around it.

[@johannjohann6523]

cool. thank you.

[@EricThompson1965]

Trident subs are not equipped with active sonar. Active is for tactical warfare. Tridents are strategic weapons, and run from any potential threat to retain their designed purpose - Nuclear deterrence

[@georgemcgnarly3144]

SSBN727 Michigan got downgraded to SSGN. Very sad.

[@draken68]

VLF means very long wavelength. Compare light being blocked by a piece of paper but longer radio waves going through building walls.

[@DDDelgado]

@19:00 better say vapour turbine, otherwise the term gas turbine is confusing, that one is used in major warships.

[@tomascernak6112]

Steam turbine. But still steam turbine is subcategory of gas turbine, so I would not see as problem at all.

[@pop5678eye]

I guess they learned the lessons from the Thresher to always have a backup generator...

[@webbtrekker534]

Lots of lessons were learned from Thresher and I put the first sub with SUBSAFE into commission as a result of that accident. We were the first submarine since the accident to not be depth restricted. Nuclear submarines have always had diesel generator back up from the beginning. You just can't run them submerged without snorkeling or you would burn up all the air inside the hull in a few minutes.

[@adityamookerjee.]

I found this one of the most interesting posts that I have seen on KZbin. Thanks! What is the difference between the eighth generation nuclear reactor for US nuclear submarines, and the previous generations? The French Navy has been using the same nuclear reactor to power their Aircraft Carrier and nuclear powered submarines over quite a few generations of the submarines, if I am not mistaken. What was the need to fit these boats with eighth generation submarine nuclear reactors?

[@sygdesignworks]

Unfortunately there's not much information available about the nuclear reactors. Not just the reactors, there's almost no info available about Ohio class submarines in general other than the basic specifications. US govt maintains a lot of secrecy about the navy tech more than the aerospace tech for some reason. Thanks for watching.

[@sygdesignworks]

@jimfrazier8611 Wow! Awesome! Thanks for watching!

[@dannywilliamson3340]

One of the main design goals was to extend the life of the fuel.....that is, more miles per gallon. That equals fewer EXPENSIVE refueling periods in drydock. And they got there.....the newest boats have cores that never need refueling in the 40 year life of the boat.

[@grogman1911]

Generations 1-7 weren't cool enough.

[@infidel_412]

I have a question concerning the torpedoes. Please bare with me as my knowledge is very limited with regard to their operations. Usually a torpedo will detonate on impact with the intended target, but, from I have seen on movies, some targets can evade torpedoes and the torpedoes run until.its energy is expended. My question, why don't they design them similar to depth charges. If the target is evading the torpedo, can it still detonate within close proximity to the target? Given a torpedo's explosive power, I believe it can still inflict some hull damage. Just asking.

[@sygdesignworks]

Good question. But torpedoes, especially the Mk-48 ones that I've shown in the video has a proximity fuse. They are magnetic proximity fuse that detonates closer to the target and inflict serious damage to hull.

[@machdaddy6451]

Very well done!

[@sygdesignworks]

Thank you very much!

[@machdaddy6451]

You're welcome. You obviously put a lot of time into it.
