Can you see outside in a submarine? Can You See Outside When You are Underwater? No, Navy submarines don’t have windows or portholes so the crew can watch undersea life.
Submarines have only periscopes for outside vision
, and those are only used close to the surface, a periscope depth (PD).
What can you see from a submarine?
How do you see where your going in a submarine?
Submarines carry an inertial navigation system
, which measures the boat’s motion and constantly updates position. Because it does not rely on radio signals or celestial sightings, it allows the boat to navigate while remaining hidden under the surface.
Do submarines have a visual?
How do people see in submarines?
Instead, submarines have
a special device called a periscope
. It allows people inside the submarine to see what’s going on above water. Where does the word “periscope” come from? It’s a combination of the Greek words “peri” and “scopus,” which mean “around” and “look.”
Do submarines hit whales?
Most subs have two types of sonar: active and passive. Active sonar sends out acoustic sounds, or “pings,” which can reach thousands of yards.
If the ping bounces back, that means it hit an object—like a whale, a ship, or another submarine.
Is there Internet in a submarine?
To connect with terrestrial technologies, the nodes communicate with gateway buoys on the water’s surface, linking to the above-sea internet via cellular networks or satellites. Still,
undersea broadband is a way off, due to the low data rates
.
Are there showers in submarines?
The showers on a submarine are set up much like the ones in your home, well kind of
. They have hot and cold water access with a recirculation pump so that the water stays hot so that you can use it quickly and efficiently by minimising water usage. Reducing water usage is a constant major driver for submariners.
Do you get seasick on a submarine?
Will I get seasick? Is it like being on a boat? Being on a submarine is very different to being on a boat. There is no rocking motion, as the submarine sits below the waves, and so
people who get seasick on a boat will not do so on our submarine
.
How long do submarines stay underwater?
Nuclear submarines can operate underwater for
three to four months
at a time and easily span seas. While few conventional submarines can travel the distance, none have the same depth of endurance below.
Why can’t submarines have windows?
A nuclear-powered submarine is not based on a combustion engine. Unlike diesel subs, a nuclear sub doesn’t need air to burn fuel and hence can remain underwater for much longer periods. How is underwater navigation performed?
Typically, submarines don’t have windows and hence the crew cannot see outside
.
Do submarines have windshields?
Navy submarines can also have windows in some cases
, but then they are installed in the sail, which is not a part of the pressure vessel and is flooded during the dive.
Are there gyms on submarines?
With a doctor on each Vanguard-class submarine and
24/7 gym facilities
– including a rowing machine, treadmill and weights – the submariners can also ensure they stay healthy. But space on board is tight, almost claustrophobic.
Do submarines make noise?
The flow noise strongly depends on the submarine’s speed
, and generally the SL is proportional to the speed raised to the sixth power. This means that doubling the speed will increase SL by 18 dB. It has been suggested that a submarine in transit is 15-20 dB noisier than one in the “quiet” mode.
Do subs have escape pods?
Some Soviet submarines like the Oscar-class submarines are rumored to have escape capsules for the crew
. (In the sinking of the Kursk the crew was unable to reach the capsule.) However, the Typhoon-class submarine is also rumored to have escape pods located near or about the sail.
What depth can a submarine dive to?
It’s generally accepted that the maximum depth (depth of implosion or collapse) is about 1.5 or 2 times deeper. The latest open literature says that a US Los Angeles-class test depth is 450m (1,500 ft), suggesting a maximum depth of
675–900m (2,250–3,000 ft)
.
Are submarines safe in storms?
Normally, a submerged submarine will not rock with the motion of the waves on the surface.
It is only in the most violent hurricanes and cyclones that wave motion reaches as much as 400 feet below the surface
. In these conditions, submarines can take a five to ten-degree roll.
Do submarines ever sink?
Nine nuclear submarines have sunk
, either by accident or scuttling. The Soviet Navy has lost five (one of which sank twice), the Russian Navy two, and the United States Navy (USN) two.
Can a submarine surface through ice?
Also, while some submarines in the Arctic have features to help surface through the ice,
they still cannot surface through ice that is greater than three meters (nine feet) thick
. Submarines that are not ice-strengthened can only surface through ice that is less than one meter (three feet) thick.
Is it cold inside a submarine?
Even though the entire submarine has air cooling facility, only two decks are air-conditioned.
The temperature in the rest of the submarine is around 30-35 degrees
and the crew works in sweltering heat. The quality of the air is monitored constantly for impurities.
Can you smoke on a submarine?
Everybody is aware that smoking is a legal, if harmful, stress reliever. So
the Navy banned smoking aboard submarines
not with the stated purpose of curing the smokers, but of protecting nonsmoking submarine crew members from the threat of heart and lung disease from secondhand smoke.
Can females be deployed on a submarine?
The Navy lifted the ban of women in submarines in 2010
and has been expanding female Sailor and officer integration ever since. In 2010, Secretary of Defense Robert M. Gates lifted the ban, which barred females from serving aboard submarines.
Do submariners smell?
You are probably wondering why I would call this post such thing…
Since Submarines remain submerged with a sealed atmosphere they rely on a chemical called Amine to remove the carbon dioxide. This chemical makes everything stink.
Can you drink on a submarine?
“
The use or introduction for drinking purposes of alcoholic liquors on board any naval vessel, or within any navy yard or station, is strictly prohibited
, and commanding officers will be held directly responsible for the enforcement of this order,” reads the hundred year-old order.
Do you have to be quiet on a submarine?
Silent running is a stealth mode of operation for naval submarines
. The aim is to evade discovery by passive sonar by eliminating superfluous noise: nonessential systems are shut down, the crew is urged to rest and refrain from making any unnecessary sound, and speed is greatly reduced to minimize propeller noise.
What do submarines do with human waste?
| CLASS | SSN 637 | NAME | Sturgeon | COMPLEMENT | 107 | NUMBER 1 | 24 |

What’s the longest time a submarine has been submerged?
The longest submerged and unsupported patrol made public is
111 days
(57,085 km 30,804 nautical miles) by HM Submarine Warspite (Cdr J. G. F. Cooke RN) in the South Atlantic from 25 November 1982 to 15 March 1983.
Can you get the bends in a submarine?
Air in a submarine is kept at a normal pressure similar to that of an airplane. Your ears may pop on either a plane or a submarine when they open the door but
you won’t get bent
because you are not being subjected to multiple atmospheres like in SCUBA diving at 100′′.
Do submarines run out of air?
How much do submariners get paid?
| Job Title Salary | US Navy Navy Submarine Officer salaries – 1 salaries reported US$87,292/yr | Royal Navy Writer/Submariner salaries – 1 salaries reported £27,264/yr | BAE Systems Submarine Systems Engineer salaries – 1 salaries reported £30,361/yr |

What is the deepest a submarine has gone?
The dive to the ocean’s deepest point turned up some surprises. The news: During a four-hour exploration of the Mariana Trench, retired naval officer Victor Vescovo piloted his submarine to
10,927 meters (35,849 feet)
below the sea’s surface, making it the deepest dive on record.
What do they eat on submarines?
How do submarines talk?
How fast do submarines go?
There are established reports and manufacturer’s claims that would indicate two (or perhaps more) submarines are capable of speeds exceeding
30 knots (56 km/h)
. In 1965, USS Albacore reported a speed of 33 knots (61 km/h), but this was not an official record.
How thick are submarine windows?
It’s currently made from
235mm-thick
acrylic glass known as PMMA. The cabin for the new sub will be 261mm, making it the thickest transparent acrylic barrier ever produced. “It’s possible for a person to go to the Black Sea’s deepest point inside a transparent pressure boundary,” Lahey says.
Is a submarine pressurized?
Pressure increases by 1 atmosphere every 10 meters
. So, yes—that submarine at 300 meters has a pressure on the hull of 31 atmospheres. Because the internal and external forces are not equal (but the surface areas are), there is a much greater force pushing on the outside of the hull than the inside.
