00:00:50

uss Pennsylvania Guy class submarine is the

00:00:53

largest submarine of the US Navy,

00:01:00

it owes another third of its existence

00:01:04

to two centuries of technological evolution, the

00:01:09

development of submarine technology

00:01:12

can be distinguished into six key stages and

00:01:14

six key submarines,

00:01:20

each of them is based on a technical

00:01:23

innovation that allows you to increase

00:01:25

the size of submarines

00:01:29

moving from one boat to another, we

00:01:32

will tell an interesting story about these ships

00:01:34

and inventions that made each

00:01:37

subsequent boat larger than its

00:01:38

predecessor 6 ingenious breakthroughs in

00:01:45

engineering, thanks to which

00:01:47

submarines became more and more larger, eventually

00:02:44

entire duration of duty which usually

00:02:46

lasts about 72 days all this time

00:03:06

any moment to release her

00:03:08

apocalyptic weapon

00:03:15

to understand how Pennsylvania became the

00:03:18

most terrible killing machine in the world

00:03:20

we need to go back in time

00:03:29

our journey begins in 1776 with the

00:03:33

first combat submarine in the world empty

00:03:36

wooden spheres with a limited supply of

00:03:38

air

00:03:40

breakthrough 1 breath underwater

00:03:48

in in the midst of the American War of

00:03:50

Independence, the Americans turned out to be very

00:03:52

disadvantageous,

00:03:55

damn it, they could not compete with the power of the

00:03:57

British fleet, our leplant

00:04:01

was based more on cunning than

00:04:04

on brute force

00:04:05

[music]

00:04:09

for its execution, a new type

00:04:12

of ship was required that would allow a person to

00:04:14

drive a bomb under water the man bomb

00:04:20

had to remain undetected

00:04:22

until they reached the British warship

00:04:28

who took it for him the man we planted

00:04:30

the bomb and hid he had to do it

00:04:34

all without lifting the

00:04:40

American engineers built their

00:04:42

ship

00:04:43

from hollowed out pieces of solid oak like a

00:04:48

barrel, both parts were held together with iron

00:04:51

hoops seam for watertightness

00:04:53

covered with resin

00:04:55

[music]

00:05:01

a container was placed under the driver's feet

00:05:04

when he pumps sea water from it the

00:05:07

ships are immersed, hiding under water

00:05:09

the driver finds himself in an air bubble

00:05:12

this is the first combat submarine in the world it

00:05:16

was called

00:05:24

John the Turtle typical commanded a nuclear

00:05:27

submarine of the Royal Navy and

00:05:30

now he will climb inside and and the

00:05:32

pedal predecessor in front of us is a

00:05:39

copy of the turtle,

00:05:41

let's start it, I smashed Egor inside

00:05:57

very closely and there was almost nothing to breathe,

00:06:00

this guy had to use his muscular

00:06:03

strength to set it in motion with the help of

00:06:05

these pedals and do the same

00:06:07

for lifting and diving,

00:06:16

in addition to the noise it produces, this is also

00:06:19

very difficult physically a tiny window

00:06:22

for viewing from the outside it will be dark at night you

00:06:25

can pump with pumps

00:06:29

only God knows how long it took

00:06:31

to get anywhere on it

00:06:33

so that I sit for only a couple of minutes and I

00:06:36

already want to get out of here on the night of the

00:06:39

engineer’s fall they attached a

00:06:41

bomb to the back of the turtle

00:06:44

they they attached a bomb holster that

00:06:47

was supposed to be embedded in the hull of the

00:06:49

enemy ship

00:06:50

when the driver reached his goal he

00:06:53

discovered that the bottom of the British ship

00:06:55

was covered with sheets of copper

00:07:00

no matter how hard he tried he could not

00:07:03

break through them and he could not attach no

00:07:11

one knows for sure

00:07:13

the submariner could have been under water breathing

00:07:15

alone and with the same air before he

00:07:18

had to stop his mission we

00:07:24

from hi I'm Kevin to try to

00:07:28

find out this we have prepared an experiment in

00:07:30

which we will use a sealed booth

00:07:32

with the same volume of air inside the skull

00:07:34

we will seal you here pedal

00:07:37

to see how long you can last

00:07:39

while you it won’t feel completely bad let

00:07:41

’s start with physiologist Dr. Kevin Fong, a

00:07:45

specialist in the functioning of the

00:07:46

human body in extreme

00:07:48

conditions, a little sealing,

00:07:54

great pedaling, let’s see how

00:07:56

things go for you

00:08:08

after 25 minutes, oxygen booths are gradually

00:08:12

coming to an end,

00:08:14

our volunteer begins to have a burning sensation in his

00:08:16

lungs, his speech becomes unclearly

00:08:19

felt that it is becoming more

00:08:21

difficult to breathe is clear less and less little

00:08:24

oxygen

00:08:27

the person sitting in the turtle must have

00:08:30

experienced similar symptoms

00:08:34

his brain was suffering from the lack of tesla

00:08:37

and would

00:08:38

begin to shut down in a matter of

00:08:40

minutes he would have lost consciousness

00:08:46

enough like you denunciation good

00:08:54

just excellent it’s amazing how

00:08:57

I felt I was suffocating there it was very

00:08:59

hot I was sweating there was not enough air how

00:09:02

good it is to be in the air again the

00:09:04

doctor's test of the fund demonstrates a

00:09:06

serious limitation of the turtle it is

00:09:08

quickly running out of air the

00:09:16

last person on board the hatch is battened down

00:09:19

dive to 50 meters

00:09:22

dive dives seen open

00:09:31

these days Pennsylvania requires

00:09:32

enough air and to

00:09:35

remain underwater for months

00:09:40

5660

00:09:45

when the hatch closes the crew is

00:09:47

locked inside for the entire duration of the mission

00:09:57

110

00:10:05

each crew member requires 12

00:10:09

cubic meters of air per day just

00:10:11

to survive and even more if

00:10:15

they work hard

00:10:25

even in such a spacious ship the

00:10:27

Pennsylvania crew would only run out of air

00:10:30

in 7 days

00:10:37

so where do they get the air the

00:10:43

answer from what they are swimming to

00:10:49

from sea water by passing an electric

00:10:54

current through the water you can split

00:10:56

this substance into its component parts hydrogen

00:10:59

and oxygen

00:11:06

chemist Andrew Schidla will demonstrate how

00:11:09

this happens here we have assembled a

00:11:15

laboratory setup

00:11:16

about a positive electrode releases

00:11:18

oxygen negative hydrogen

00:11:21

now I'll show you how we collect

00:11:23

oxygen and then light the adhesive sliver

00:11:26

proved that this is the gas we need now I'll

00:11:29

carefully open the valve and look

00:11:38

now we have a full test tube of

00:11:40

oxygen let's do a classic test for

00:11:43

oxygen and see we can light the

00:11:45

adhesive sliver for him so 1 2 3 4

00:11:54

new world record 6 with just

00:11:57

wonderful we got oxygen from

00:11:59

water by electrolysis in Pennsylvania

00:12:04

also electrolysis is used to

00:12:06

get oxygen from sea water

00:12:08

only on a much larger scale it's an

00:12:12

oxygen generator

00:12:13

his name is Paris after one of the

00:12:16

hilton sisters number one is called Nicky because that

00:12:19

we believe that some are better, no offense and

00:12:24

some produce more than 4000 liters of

00:12:27

oxygen per hour,

00:12:32

oxygen is used to enrich the

00:12:34

exhaust air which is then

00:12:36

returned to the circulation system of the

00:12:38

submarine, crystal clear air and all

00:12:42

thanks to the hilton sisters

00:12:45

we need to breathe if this installation does not

00:12:49

produce oxygen for us then we

00:12:51

won't be able to breathe so I'm trying to keep an

00:12:53

eye on her to make sure she

00:12:54

's happy

00:12:55

more than two centuries ago a turtle man

00:12:58

could stay under water for only 25 minutes

00:13:02

these days in Pennsylvania the supply of air is

00:13:05

endless

00:13:11

in 1776 a barrel man was able to prove

00:13:16

that even the most powerful warriors ships are

00:13:18

vulnerable to attacks from under water but to

00:13:25

take advantage of this weakness the edge

00:13:27

engineer will have to build a

00:13:29

much larger submarine

00:13:30

13 meter submarine and man hanley

00:13:33

and come up with a way to control it

00:13:39

breakthrough 2 maneuverability weapons at the

00:13:45

ready rain during the

00:13:55

American Civil War engineers tried to

00:13:57

expand the horizons of military technology

00:14:00

but they did not limit themselves only to

00:14:03

land weapons, they also

00:14:08

invented underwater weapons called

00:14:11

the pole moon and a barrel of gunpowder

00:14:13

mounted on the end of a pole in front of the

00:14:15

submarine.

00:14:19

The device was powerful,

00:14:21

but the task of hitting the target and taking the

00:14:24

submarine to a safe distance was

00:14:26

associated with significant difficulties. The

00:14:31

main problem was 6 of their memes. was that

00:14:33

they are physically connected submarines need to

00:14:37

bring the uterus to the depth at which it

00:14:39

would meet the target

00:14:40

too shallow and jump out of the water

00:14:43

too deep and you will pass under the keel

00:14:45

of the ship probably at the depth the target will be

00:14:48

hit well the shipbuilder

00:14:52

professor of slaves and his colleague are

00:14:54

trying to control the depth of

00:14:56

their immersion model of a submarine, letting

00:14:59

air in and out of it is easier

00:15:01

said than done and we will try to

00:15:04

demonstrate it to you well ready and

00:15:06

so I begin to let out air let's go

00:15:10

now the problem is that we stop it

00:15:19

Mainz my edge is rising but I

00:15:21

overdid it so

00:15:23

now I let out too much,

00:15:27

you'll have to let in some air like

00:15:31

that, it just sank like blood, you can't

00:15:34

see the creators of the first submarines

00:15:41

tried to improve the controllability of their

00:15:43

brainchildren by installing large metal

00:15:45

weights on guides inside the hull, the

00:15:50

operator can move the weight back and

00:15:52

forth to change the tilt of the submarine,

00:16:00

but during the test the operator moved the

00:16:02

weight too far forward

00:16:06

the ship nosed down so steeply that it was

00:16:09

unable to lift the load back this system is

00:16:14

not accurate enough to be

00:16:16

used by pole mines the type the

00:16:22

creator of the first submarines did

00:16:25

not actually know how to control them

00:16:26

they turned to nature for inspiration they

00:16:29

copied the fins of the fish to install a

00:16:31

metal rudder and fins on the sides of the

00:16:33

submarine, this is exactly what the Southern engineers

00:16:37

did with their Hanley submarine,

00:16:41

sitting inside the captain could raise and

00:16:43

lower the rudder and using levers

00:16:47

when the roles are directed downwards, the water flowing around them

00:16:50

creates more pressure on the upper

00:16:53

surface of the rudders than on the lower ones, this

00:16:56

pressure forces the toe to go down,

00:17:01

this will allow the captain accurately

00:17:03

control the depth and direction of

00:17:05

attack

00:17:10

he tests this technology on an

00:17:13

unsuspecting Yankee warship

00:17:19

using the rudder and to bring the boat to the

00:17:22

desired depth the hanley sticks a pole

00:17:24

mine into the ship's hull

00:17:32

becomes the first submarine to sink a ship and a

00:17:35

ship

00:17:37

and the role was a giant leap

00:17:40

forward in the development of submarines boats

00:17:42

because it was the first design

00:17:43

that could be controlled with sufficient

00:17:46

accuracy in course and depth to

00:17:48

use underwater weapons against the

00:17:50

most vulnerable part of the surface of the ship

00:17:52

in order to sink it

00:17:58

like its predecessor, the Hanley, the

00:18:00

Pennsylvania also has fins

00:18:02

called rudders,

00:18:07

they are controlled by the

00:18:09

two youngest crew members on on a

00:18:11

ship, the control post is one of the first

00:18:17

places where our young submariners end up,

00:18:20

some of these guys are 18-19 years old,

00:18:24

it is they who control the movement of the

00:18:27

submarine in the water, he controls the rudders

00:18:31

located on the conning tower, they are very

00:18:34

good at maintaining the depth of the

00:18:38

operator’s commands via wires, they are transmitted

00:18:41

to the roles located on in the wheelhouse

00:18:47

I control the angle of their inclination, it can

00:18:49

raise or lower the submarine in the water column

00:18:54

in Pennsylvania, there is a second set of

00:18:57

rudders in the rear part,

00:18:58

from this remote control the stern rudder is controlled

00:19:01

and whose angle of inclination you can see on

00:19:04

this scale of the pocket and the rudder and is located at the very

00:19:07

tail of the submarine almost like the

00:19:09

plane's elevator they control the angle of

00:19:11

the boat

00:19:18

you're kind of flying on this submarine underwater

00:19:46

[music]

00:19:50

while eating we usually

00:19:53

level the boat so that the food drinks and

00:19:55

everything else doesn't move off the table me

00:20:01

then we start the ascent or dives

00:20:03

to practice and they're there downstairs

00:20:05

playing catch the plate in 1864 the fins

00:20:15

gave the Hanya boat maneuverability but she

00:20:17

needs to hit the target to deliver

00:20:19

her deadly cargo

00:20:24

this exposes her to significant risk

00:20:32

in the capital for another 80 years before an engineer

00:20:35

perfected the skill of striking from a

00:20:38

distance with this one of the

00:20:41

most infamous predators of the second

00:20:43

world war

00:20:44

german submarine and 66 starboard in 3

00:20:51

torpedo

00:20:56

during the second world war german

00:20:59

submariners needed a way to attack

00:21:01

allied ships from a distance

00:21:05

there is one type of weapon suitable

00:21:08

for this purpose a self-propelled torpedo

00:21:14

and and sets in motion a compressed air cylinder

00:21:19

when launched the valve opens and the air

00:21:22

is released in 20 indra

00:21:28

movement of the piston and rotates the propeller pushing the

00:21:31

torpedo,

00:21:35

but this torpedo has a significant

00:21:38

drawback: the

00:21:39

compressed air driven

00:21:42

leaves a noticeable trail of bubbles, this

00:21:47

makes it possible to notice its approach

00:21:57

or the German fleet developed a

00:22:00

new torpedo that would not reveal

00:22:02

its position; a trail of bubbles

00:22:04

it does not work in the heat of the air, this new

00:22:12

torpedo is powered by a small

00:22:14

electric motor,

00:22:18

but to power it, it requires a huge

00:22:21

battery; to accommodate the battery, the torpedoes

00:22:27

must be more than seven meters deep,

00:22:29

and in order to accommodate 22 such

00:22:35

torpedoes, the submarine itself must be

00:22:37

huge

00:22:39

[music] the

00:22:44

result was gear 66 70 cm long

00:22:58

underwater killer sank 33 ships

00:23:02

of war and her huge supply of torpedoes allowed

00:23:06

her to attack again and again without needing to

00:23:08

return to base to replenish her

00:23:11

stock of torpedoes 07 enemy

00:23:15

underwater target detected,

00:23:25

preparation for torpedo launch recommended,

00:23:30

prepare for torpedo launch, sound

general alarm signal sir

00:23:38

[music]

00:23:44

today is the tenth day of the Pennsylvania patrol,

00:23:47

the crew is conducting a torpedo exercise, that's

00:23:53

right sir, they're on 07 hard line on a

00:24:59

behind the tail of the torpedo there is a

00:25:02

00:25:39

sound of an explosion in the south in 1943 and 66 it could

00:25:49

attack several targets without

00:25:50

the need to return to base to

00:25:52

replenish ammunition; its

00:25:58

voracious engines quickly consumed all

00:26:00

the fuel

00:26:05

so that the submarine could remain sea longer; an

00:26:08

engineer who worked on the even

00:26:10

larger American submarine Nautilus

00:26:13

had to find a new source of energy

00:26:15

breakthrough 4 power plant

00:26:23

during of the Second World War, the German

00:26:25

fleet had to urgently solve the problem of

00:26:27

refueling

00:26:29

its submarines tried to destroy the

00:26:32

supply routes from ships coming from North

00:26:35

America for this purpose the submarines went

00:26:39

far from home and fuel

00:26:44

they needed a way to refuel by the sea

00:26:49

so the Germans invented a submarine which

00:26:52

is more of a tanker than

00:26:55

combat vehicle, they called it a cash

00:27:00

cow, to build it, the engineers

00:27:03

took a standard submarine and installed

00:27:06

additional fuel tanks on it; they could

00:27:11

hold up to 400 tons of fuel;

00:27:20

in order to transfer this fuel to the cash cow, they

00:27:23

had to surface and deliver a

00:27:25

fuel hose to another submarine

00:27:31

in the five hours it took them to leave for

00:27:33

refueling, both submarines could not

00:27:35

dive to a safe depth, which

00:27:37

made them vulnerable to attack,

00:27:41

it is clear that for the British, cash

00:27:43

cows were the most important goal

00:27:45

if you succeed, but I know, sinking

00:27:48

them would reduce the effectiveness of all

00:27:50

other submarines in the Atlantic

00:27:57

by the end of the war, the Allies sank all 10

00:28:00

German cash cows

00:28:05

the lesson was clear refueling a submarine at

00:28:08

sea is too dangerous

00:28:13

engineers needed to find a way to make

00:28:16

the fuel last longer

00:28:18

name

00:28:25

the answer to this question was 145 m with the

00:28:28

beginning of the atomic age

00:28:31

American scientists tried to

00:28:33

use the colossal energy

00:28:35

released by the splitting of the atom to

00:28:38

provide energy for their new

00:28:40

submarine, they installed a

00:28:44

nuclear reactor on it,

00:28:46

uranium is split in it, which leads to a

00:28:48

strong release of heat, this heat

00:28:55

is used to generate steam, the

00:28:57

steam is fed to several durbines

00:28:59

causing their blades to rotate at high

00:29:02

speed

00:29:11

in turn and rotates the propellers

00:29:19

but the nuclear reactor is very large for the

00:29:23

submarine to accommodate it there must be

00:29:25

enormous

00:29:30

technical difficulties associated with the

00:29:32

placement of the nuclear reactor in the

00:29:35

submarine hull were incredible

00:29:36

no one had ever created a nuclear

00:29:39

reactor of this type no one had

00:29:41

deliberately tried to install it on

00:29:43

submarines and submerge the sea no one

00:29:46

actually knew how much energy

00:29:48

can be obtained from a

00:29:50

dhow reactor no one had done this before

00:29:55

American engineers accepted this challenge

00:29:57

and in 54 they introduced the USS nautilus to the world

00:30:02

[music]

00:30:07

and there was no need to refuel at sea

00:30:09

it was capable of making an unprecedented

00:30:12

journey of 100 thousand kilometers with only

00:30:14

4 kilograms of uranium fuel

00:30:20

[music ]

00:30:22

the effect of the Nautilus 1 1 submarine

00:30:25

was incredibly

00:30:27

suddenly the Marine appeared capable of

00:30:29

operating anywhere in the world and

00:30:31

able to get there all the way while

00:30:33

under water

00:30:37

these days in Pennsylvania the plant has an

00:30:40

impenetrable bulkhead where one

00:30:43

of the most secret examples of military

00:30:45

equipment is located - a nuclear reactor submarines

00:30:53

of the author much more powerful than the prototypes that

00:30:55

were installed on the nautilus

00:30:58

it produces more than enough energy

00:31:03

for a Pennsylvania

00:31:04

weighing 17 thousand that it could move

00:31:07

underwater at a speed of 45 kilometers per

00:31:10

hour it also provides energy for many

00:31:15

different machines and instruments on board

00:31:18

it is powered by a piece of uranium and the size with a fist,

00:31:21

but so far there are no signs that

00:31:24

it needs to be replenished,

00:31:25

you yourself, this submarine is important in operation in the

00:31:28

eighty-ninth year, 20 years ago and has

00:31:31

never been refueled yet,

00:31:34

the only thing that limits our

00:31:36

ability to be at sea is this food,

00:31:40

so the range of action of Pennsylvania is

00:31:43

actually in fact, it limits the fuel

00:31:45

for the crew rather than for the submarine itself.

00:31:48

On board there is a supply of food for

00:31:50

three months and here the food is one of the

00:31:52

best in the flesh and up to also a very important

00:31:55

means of raising the morale of the

00:31:57

crew locked under water in a steel

00:32:00

pipe

00:32:01

Saturday evening evening pizza

00:32:07

I don’t really like sausage

00:32:11

pizza with Philadelphia sauce barbecue even

00:32:19

during meals the crew is

00:32:21

constantly ready to sound a

00:32:25

general alarm

00:32:28

[music]

00:32:31

the main fear of submariners is fire,

00:32:34

so they conduct fire

00:32:37

drills no less often than they eat pizza 15 seconds

00:32:41

course is even 350

00:32:45

alarm in the torpedo compartment

00:32:52

they learned a Russian lesson submarine Kursk

00:32:56

it sank in 2000, the entire crew

00:33:00

died

00:33:05

when it was raised from the bottom until it became clear

00:33:08

that the crew needed too much

00:33:10

time to extinguish the fire and the submarine

00:33:12

exploded

00:33:18

[music] the

00:33:19

captain and gives the crew only six

00:33:22

minutes to extinguish the training fire

00:33:26

[music]

00:33:31

fire chief gives a signal

00:33:34

that the fire has been extinguished on time regular

00:33:36

exercises this result in

00:33:44

1954 the nautilus could prove that

00:33:47

submarines are capable of staying at

00:33:49

sea almost indefinitely

00:33:51

thanks to nuclear energy

00:33:54

[music]

00:33:56

the nautilus was limited and the armament was

00:33:59

only torpedoes with conventional warheads

00:34:06

the engine on the submarine was nuclear and the

00:34:09

us navy also wanted to switch to

00:34:11

nuclear weapons,

00:34:15

their submarines had to increase in

00:34:17

size to accommodate such

00:34:19

weapons

00:34:22

breakthrough 5 nuclear strike

00:34:27

[music]

00:34:28

in the 50s, scientists on both sides of the

00:34:31

Iron Curtain entered the race to

00:34:33

create an atomic bomb with rocket thrust,

00:34:43

what could be it’s better to launch and and from a

00:34:47

submarine

00:34:50

placing this weapon on a

00:34:52

submarine is quite simple

00:34:53

Sapsan Marina is difficult to detect and

00:34:56

thus it is a safe base from

00:34:58

which you can launch nuclear strikes your

00:35:01

Russian was the first to achieve this

00:35:10

their missile was so long that the

00:35:12

only place where it was possible

00:35:15

shove was the back of the conning tower

00:35:18

for launch submarine

00:35:22

surface and raise the missile

00:35:24

above the deck

00:35:28

but a submarine on the surface is an

00:35:30

easy target for an enemy

00:35:32

bomber

00:35:38

the Americans wanted to develop the Soviet

00:35:41

breakthrough even further and create a

00:35:43

submarine capable of launching missiles without

00:35:45

the need to surface

00:35:48

[music]

00:35:55

difficulties The ones facing the Americans

00:35:57

were incredible,

00:35:58

they were creating a submarine that

00:36:01

was supposed to launch rockets from under water, but

00:36:03

no one had ever launched a rocket from

00:36:06

water before; the rocket engine requires

00:36:09

air, so they cannot work under

00:36:12

water, so the engineers decided to

00:36:14

use compressed air instead, all

00:36:18

often from there he will demonstrate to us one

00:36:20

experiment, a rocket guide, compressed air, all

00:36:24

that is needed is a means of just giving a rocket, I

00:36:27

am restoring the rocket on the launch morning in

00:36:29

Baltic three two one fire, thank you

00:36:36

very much, but this is not very

00:36:38

indicative, isn’t it, because the

00:36:40

submarine will be under water, so the tube

00:36:42

will be filled with water, this is a much

00:36:45

more realistic installation, we have a

00:36:47

rocket in a tube, the whole structure

00:36:49

is under water, so now

00:36:53

the rocket needs to not only fly out of

00:36:55

the tube, but I also need to rise from the

00:36:57

depths, overcoming the pressure, and so Tristan,

00:36:59

let's see what happens ready three

00:37:02

two one fire

00:37:06

quite disappointing with what kind of

00:37:09

solution we assembled the installation with the rocket

00:37:12

placed in a dry tube sealed

00:37:14

at the top the question is only there you will put on a

00:37:17

tight enough yarn over but will never

00:37:19

pour the top film

00:37:21

Tristan let's see what will be

00:37:30

well prepared for launch 321 it is obvious that

00:37:39

the system works so the secret in the

00:37:44

sealed lid does not give water

00:37:46

to flood the launch silo when the lid is

00:37:47

opened and a

00:37:51

moment before launch the cap explodes

00:37:55

and before the water has time to fill the silo a

00:37:59

valve opens that shoots out

00:38:00

compressed air at the base of the launch

00:38:02

silo the

00:38:08

air pushes out the missile silos at a

00:38:10

speed of more than 80 kilometers per hour and the

00:38:14

acceleration is sufficient to

00:38:16

penetrate almost 40 meter layer of water

00:38:24

already with the music of the rocket engine are launched by

00:38:30

USGeorge Washington armed with 16

00:38:34

new polaris missiles went to sea in

00:38:37

1960 the power of each rocket is 40

00:38:41

times greater than the power of the atomic bomb

00:38:43

dropped on Hiroshima

00:38:44

and George Washington can launch them

00:38:47

hiding under water from anywhere on

00:38:49

earth ball is a

00:38:51

terrifying prospect,

00:39:01

such missiles installed on submarines

00:39:04

effectively deterred the use of force

00:39:06

by the fact that they are so destructive that the

00:39:08

very idea of war between nations

00:39:10

possessing such weapons has become

00:39:13

impossible prepare for the launch of missiles

00:39:24

senior vaccines and sound a general

00:39:26

alarm general alarm has been raised now 15th

00:39:31

day of the mission captain arrange for the

00:39:32

crew Well-practiced

00:39:34

nuclear strike exercises and from

00:39:39

Pennsylvania are armed with twenty-

00:39:41

four trident nuclear missiles and

00:39:43

are in constant readiness to

00:39:45

respond to an order to launch them and the

00:39:48

captain received a Batak message

00:39:50

search direction target group number 01

00:39:53

please confirm confirm message

00:40:01

golf oscar nuclear missile launch command

00:40:04

encrypted to make sure

00:40:06

that the order was received from the President himself, the

00:40:11

captain, the message is genuine, I agree, I agree, I agree to

00:40:14

launch, I agree, I agree, the

00:40:16

fire control station, I authorize the launch,

00:40:18

permission to launch was received from post

00:40:25

a 5, the launch silo, these missiles are so

00:40:31

large that it takes something more powerful

00:40:33

than compressed air to push them out of the

00:40:35

water to Pennsylvania uses a

00:40:39

small rocket engine

00:40:41

which hits a tank of water, the water

00:40:43

overheats and instantly turns into

00:40:46

steam,

00:40:52

pushes the rocket out of the water onto the surface

00:41:03

of the warhead, one of this submarine

00:41:05

is destructive than all the bombs dropped and

00:41:07

during both world wars combined in the

00:41:17

sixties with George Washington

00:41:19

was able to arrange nuclear

00:41:21

apocalypse

00:41:22

but the enemy was still able to detect

00:41:25

her presence the

00:41:29

next trick that

00:41:31

the designers had to do was not only to

00:41:33

make the boat larger

00:41:34

but to make it invisible breakthrough 6

00:41:44

invisibility

00:41:49

light does not penetrate into the depths of the oceans

00:41:52

further than a few hundred meters,

00:41:55

however sound waves can travel

00:41:58

many hundreds kilometers

00:42:00

[music]

00:42:03

and those who hunt her from Pennsylvania

00:42:06

listen to all the noise that she

00:42:08

makes and with which the

00:42:10

central post 379 can give away her location

00:42:16

to be invisible Pennsylvania

00:42:18

must be silent one of our

00:42:22

main tasks is to remain unnoticed

00:42:24

day after day and honestly we must

00:42:27

remain silent so that no one knows where

00:42:29

we are

00:42:30

except ourselves,

00:42:37

everything on the submarine bridge of the

00:42:39

equipment of the working machine and even the

00:42:42

hand dryers are

00:42:43

isolated with rubber

00:42:45

shock absorbers to reduce noise

00:42:47

caused by vibrations. Another strong

00:42:54

source of noise emitted by the ocean

00:42:57

is the mushroom propeller and your mind a

00:43:00

wide range of frequencies can

00:43:02

propagate in the ocean over a huge

00:43:04

distance

00:43:05

before designers can create a

00:43:07

silent propeller, they need to understand why it

00:43:10

creates such noise if the propeller rotates

00:43:13

quickly, a foam trail remains behind it

00:43:15

[music]

00:43:19

bursting bubbles make a lot of noise,

00:43:26

these bubbles are not filled with air,

00:43:28

the apparatus is formed by vapors when boiling

00:43:33

water

00:43:36

these are widely known that water boils at

00:43:39

one hundred degrees Celsius however not many people

00:43:43

know that at different pressure water boils

00:43:45

at a different temperature if you

00:43:47

increase the pressure such as a pressure

00:43:49

cooker the boiling point of water

00:43:52

increases thus

00:43:54

cooking becomes more

00:43:56

efficient few however know that with

00:43:59

lowering the pressure, the water will boil at a

00:44:01

lower temperature,

00:44:03

here I have a vacuum and I

00:44:06

turn it on, this flask contains water, it is

00:44:09

connected to a pressure gauge, now the pressure is

00:44:12

about 1 kilogram per square

00:44:14

centimeter 1 atmosphere, I turn on the pump,

00:44:17

you can see how

00:44:20

the pressure immediately began to drop as As soon as we begin to

00:44:22

approach zero, bubbles appear

00:44:25

and the water begins to boil, even at

00:44:27

room temperature,

00:44:29

but at a reduced pressure,

00:44:31

almost at a complete vacuum, the water has boiled, the

00:44:34

water is boiling at 20 degrees Celsius,

00:44:36

at almost zero and kilograms per

00:44:39

square centimeter of silver from because

00:44:43

this is actually in fact, an amazing phenomenon

00:44:45

with

00:44:50

when the submarine propeller rotates at

00:44:52

high speed, zones of low pressure are formed on the blades;

00:44:57

vacuum causes water to boil without

00:45:00

heating and forms steam bubbles;

00:45:05

this process is called cavitation;

00:45:13

it is only the formation of these bubbles that

00:45:15

depends on the speed of rotation of the propeller; the

00:45:18

faster, the greater the risk of cavitation;

00:45:22

device when the pennsylvania

00:45:24

is kept a closely guarded secret but the

00:45:27

basic principles of a low noise propeller are

00:45:29

known cavitation occurs when the propeller

00:45:36

rotates at high speed

00:45:38

slowing down the propeller reduces cavitation and

00:45:41

thus machines but slowing down the propeller

00:45:45

reduces the speed of the pud

00:45:47

to solve this problem engineers

00:45:51

here or a unique wine with four

00:45:52

additional blades special for

00:45:55

more

00:45:59

they create enormous thrust well at a much

00:46:01

lower rotation speed

00:46:04

so on the Pennsylvania there is almost no

00:46:07

cavitation

00:46:08

and therefore no propeller noise she is a

00:46:13
