I was expecting you would explain in detail how they release and replenish the air in those ballast tanks. Yes, you talked about releasing the air but how do they get air back in to let the sub float?

Amor Marzan Air can be compressed, and when that happens you change the density of it. Lots of air can be stored when it's compressed. Here's a formula (Pressure)×(Volume)=(moles)×(gas constant)×(Temperature). When you keep the same amount of gas, the 'moles', but at a lower volume pressure goes up to account for it being squished. When it's released to a greater volume it will attempt to return to atmospheric pressure and push the water out. They get new air from surfacing and compressing it down for later use.

+CharlieMason Well submarines do have "wings" but they're called planes. At the forward end they're called bow planes. the aft end they're called stern planes. These change the pitch of the submarine. The Bow planes change the pitch alot and the stern planes change it slightly. To surface both of these planes force the ship up and while on the surface the submarine uses a series of low pressure blows to force air into the ballast tanks. the pressure inside will force the water down and out of the ship. There are other ways to surface the ship but this is the preferred way.

There are a number of high pressure tanks scattered throught the ship that store compressed air. They're kept topped up all the time since there are many small devices that use compressed air.

There are three ways to surface a modern submarine. The most common is a low-pressure blow. Come up to periscope depth, extend the snorkel from the sail. Now you have a way to get air from the surface into the boat. Fire up the low pressure blower and start pushing air from inside the boat into the main ballast tanks. It's really pretty simple, but you can only do that if you have air coming in through the snorkel. The other two options used high-pressure air stored in the high pressure air flasks. If you do this quickly, it's an emergency blow, and it's used for emergencies. Or if you're trying to surface through ice, a different set of valves are used to slowly and gently add high pressure air, just enough to push through the ice. That's called an arctic blow. Of course if you use high pressure air to surface, you have to spend time running compressors to recharge the flasks. So the low pressure blow is preferred when possible. Low pressure blow is also used a couple times a day to remain surfaced. The air in the ballast tanks slowly dissolves into the sea and it's possible that the vents might leak a little. So it's standard procedure to periodically add more air until bubbles come out.

I don't understand the affect of internal vs external ballast tanks on buoyancy. The video didn't explain it well.

Video only yells u how they dive which is by filling up the ballast tanks with seawater. But it DID NOT tell how they surface, contrary to what the title says. Of course we know they blow the ballast tanks by pumping air to displace the seawater. But how do they pump in the air obviously not explained

A normal surfacing is accomplished by coming to periscope depth, raising the snorkel mast, and using the high-volume blower to deballast the MBTs. Less noise that way.

What's the name of the first music?

I was on the USS Michigan SSBN 727. Subs surface using an EMBT blow (Emergency Main Ballast Tank). It was 4500 psi air pushes out water through vents in the ballast tanks. That's for an emergency surface. Otherwise it's just moving water out or drawing water in to affect buoyancy also using forward an aft trim tanks for stability. Salinity of sea water also affects the buoyancy and has to be taken into account. The USS Thresher was lost in this way on it's DASO run when performing an EMBT blow. Somehow there moisture in the ship's service air lines and that 4500 psi air (or whatever psi they had) froze the lines and they couldn't expel water. To the bottom they went. Eternal Patrol is what it's called.

For gaining oxygen gas in submarine underwater , they use Na2O2 (Sodium peroxide )filled boxes in submarine ,when the passengers in submarine releases CO2 ,the sodium peroxide boxes absorbs the CO2 and it reacts with this and then , releases O2 so that the passengers or anyone in submarine can survive or take in respiration 🙏🙏

They can also make gaseous oxygen and hydrogen when submerged by electrolysis.

How do they surface? You may ask... So submarines have ballast tanks as in the video if you fill them or flood them it makes it heavy and makes the sub dive. Then on ballast tanks there are 4, flood, blow, equalize, and closed. So they set it to blow to go up which takes all the water and shoots it out very quickly, I hope this solved some of the confusion in the comments.

I wonder if the Navy is experimenting with a 360° camera and a VR headset. While everyone else would watch a monitor, there could be one person who acts as though he's "above" the water, being able to look around quickly.

Sail houses periscopes.

So, imagine making the periscope the height of the sail and into the hull, but still using photonics. Now you can have a periscope that extends twice as far allowing the submarine to be twice as deep at periscope depth. Making it less visible from the air. And still have the ability to put the control room on the 2nd level.

well that was disappointing.... a few moment of ballast and i still don't understand what the heck hes saying and then mostly move on to periscopes.

So I guess the submarine never surfaced again

For the submarine to surface, water is ejected out of those ballast tanks which reduces the weight of the submarine. Those ballast tanks can be filled with either air or be void (under vacuum). I don't know what happens in those tanks (most likely refilled with compressed air and those ballast tanks will probably have negative pressure), but just from pure logic and some physical understanding...it's simply from ejecting the water out of the ballast tanks. Objects don't float because of "air" in them...it's that the volume and weight of the object that matters. Whenever an object displaces fluid, there is a force exerted back on the object known as "buoyant" force. For example say a 1lb ball sinks to 50% of it's diameter (half of the balls height sinks under the water line) and it stops sinking. This is due to the ball displacing a volume of water that is equal to 1lb. If you made the ball heavier (say inject water into the ball)...then the ball will sink until the weight of the water displaced equals the weight of the ball. If you make the ball lighter (say remove the water from the ball), then the ball will rise. This video did a piss poor job of explaining anything.
