Submarines generally don’t have windows because they run underwater and the windows would be quickly destroyed under the intense pressure of the ocean depths. Also, the windows would let water into the submarine and introduce potential risks to its crew and internal mechanisms.
Moreover,submarines rely on sonar to detect ships, underwater objects, as well as to find their way through the water and having a window would disrupt the sonar’s ability to detect with accuracy. Submarines can often spend days or even weeks underwater at a time so having a window would also negatively impact the mental health of the crew since they would not be able to clearly see what was outside.

Do any military submarines have windows?
No, military submarines do not have windows. A submarine is the most efficient way to travel through water, but the tight and enclosed space does not allow for windows. While it’s a common misconception that submarines don’t have windows, the reality is that windows would make them much less efficient underwater.
To keep the vessel water-tight and secure, most submarines are designed with small ports which are covered with thick transparent plastic. These ports can be opened underwater to take pictures or record footage but they are meant to be tightly sealed when in operation.
To allow submarine crews to see the surface at night, many submarines are now equipped with external cameras that project live images onto monitors inside the vessel. This gives sailors the opportunity to observe the environment without impacting the subs speed or efficiency.
Military submarines are not designed to be leisurely or comfortable like cruise ships, but with advancements in technology, life inside a submarine is becoming more hospitable.
Why can’t a woman be on a submarine?
It has historically been a long-standing military policy that women have not been allowed to serve on submarines. This policy has been based in part on the fact that submarines are designed to operate in a highly compressed environment, meaning that the entire crew has to live and work in tight quarters for long periods of time, with minimal privacy and limited space for recreation.
There have also been military policy considerations for not having the two genders living in such close proximity for extended missions on submarines. Additionally, due to the “closed hatch” nature of a submarine, the physical safety of crew members of both genders must be considered, as the confines of a submarine can create opportunities for inappropriate conduct without proper oversight.
The policy of exclusion for women on submarines is now being reviewed by certain militaries at this time, and there is a growing consensus that the exposure of both genders to each other on a submarine can be managed in a way that minimizes any security risks as well as potential interpersonal issues associated with privacy and recreation.
Despite these advances, the policy of exclusion of women on submarines still remains in place in many militaries around the world.
Why do Russian subs have windows?
Russian submarines feature windows made of thick transparencies due to a variety of factors. Firstly, in comparison to conventional submarines produced in other countries, Russian submarines usually operate at a much deeper depth and require more external light sources when navigating, so windows can provide greater visibility and help the crew better detect surrounding objects.
Secondly, newer Russian submarines feature a two-seat navigation compartment which is connected to the external world through a nose-mounted window, allowing for better communication and situational awareness.
Additionally, many Russian submarines have a watertight hatch at the bottom so that visual inspections can be conducted without the need for a special diving suit. Finally, windows made of thick transparencies can provide the crew with a much better view of the surrounding environment, allowing them to plan their course and make proper decisions.
All of these factors combined make windows a crucial element in any Russian submarine, as they provide invaluable information to the crew and enable them to make the most of their time underwater.
What is the longest a submarine has stayed submerged?
The longest recorded time that a submarine has stayed submerged is the 668-day voyage of the Russian submarine K-141 Kursk, which occurred in 1995. The Kursk was a nuclear-powered cruise missile submarine of the Oscar class.
On August 12, 1995, the submarine dived in the Barents Sea for a large-scale naval exercise and unfortunately became irrevocably stuck on the sea bed, caught between two submerged rocks. The submarine rapidly started to take on water and sink, and all 118 crew members on board were lost.
The Kursk remained immobile at the bottom of the sea for 232 days until it was recovered on October 28, 2000, after a complex and lengthy multinational effort. Since then, no submarine has stayed submerged for a longer period of time than the Kursk.
Why are submarines not painted blue?
Submarines are not painted blue for a variety of reasons. First and foremost, the colour blue does not work well for camouflage purposes on the ocean. Blue reflects light, which means it can be easily seen from afar.
This can make it easier for submarines to be detected from the surface.
Plus, the colour blue can be visible against the backdrop of the ocean floor. This makes it easier for submarines to be detected by underwater sonar. Therefore, the dark colours are typically used to provide the best camouflage purposes.
In addition to camouflaging, old naval tradition has also had an influence on why submarines are not painted blue. Early submarines during the wars were painted black with grey or green accents. This helped them blend in with the dark nature of deep water, so many navy forces still use this colour scheme.
Finally, painting a submarine is expensive and requires a lot of maintenance. Therefore, it’s important to use a colour scheme that will provide the best protection and last the longest. Light colours can fade faster and be more susceptible to rust or damage from Sea creatures, making dark or neutral colours a better option.
Do US Navy ships have windows?
Yes, US Navy ships do have windows. Windows on Navy ships are made of thick Plexiglas or Lexan to provide insulation and protection from the elements. Most of these windows line the living areas of the ship and are typically found in the mess, recreation, and sleeping areas.
For example, berthing spaces typically have multiple windows that let in natural light. However, the placement of windows on modern Navy ships is often relatively limited for safety reasons, with most being concentrated around the outer rim of the ship.
On aircraft carriers, windows are also found in the pilot ready rooms, as well as in the bridge and bridge wings. Furthermore, some larger vessels have lounge areas and meeting rooms that have additional windows.
What are windows on submarines called?
Windows on submarines are known as periscopes. Periscopes allow submarine crew to look outside and survey their environment for other ships, possible landings, and other potential threats. Periscopes are tall poles mounted on the submarine with a viewing port at the top, allowing submarine crew to peer out of the view port and take note of their envelope.
Periscopes typically consist of two mirrors, an eyepiece, and a sliding tube with a set of lenses to focus the image. Typically the periscope is placed in the conning tower of the submarine, where it can get a clear view of the surrounding environment.
This allows the crew to maintain a low profile and keep their craft out of sight from enemy vessels.
Do submarine conning towers have windows?
Most modern submarines do not have conning towers, though many older models did. Conning towers are a type of enclosed bridge in a submarine, essentially a vertical tab above the surface of the water from which the submarine is navigated and from which observations can be made.
Submarine conning towers were originally open, usually fitted with a periscope or just with an observer looking out through the open area, making communication with the surface very easy. Modern deep-diving submarines have almost entirely done away with the conning tower, due in part to its tendency to attract enemy fire and its limited range of vision.
Therefore, most submarines built today do not have any of the traditional viewing windows or ports in the conning tower.
The most modern submarines in operation do, however, use a similar concept to the conning tower, called a sail. This is a much more streamline version of the traditional conning tower, allowing the submarine to dive deeper and travel more quickly on a more aerodynamic form.
However, the sail is again typically enclosed, under the surface of the water, and does not have any windows for observation.
Does the US have secret submarines?
Yes, the United States does have secret submarines. These submarines are known as Nuclear Submarines, and they are operated by the US Navy to detect and destroy enemy warships and submarines, as well as provide intelligence information while underwater.
Additionally, they are used for the transportation of personnel, supplies, and weapons to strategic locations. Nuclear Submarines are an integral part of the US military’s defense force and their exact capabilities are classified.
Despite the secrecy, it is known that these vessels are equipped with advanced technology and have a stealth factor, allowing them to remain undetected for long periods of time. These submarines typically have a shoulder patch, symbolizing their position in the Navy forces, that reads: “Stealth Silent Service.
” These submarines are able to traverse at high speeds and travel to depths upwards of 400 meters underwater, which is far beyond their adversaries. Nuclear Submarines are essential for the safety and protection of the US, and their existence is a testament to the technological advancements of the US Navy.
Why are girls not allowed in submarines?
There are a variety of reasons why girls are not allowed in submarines. First and foremost, the tight spaces and low air circulation in submarines pose unique health risks. The lack of air circulation increases the risk of carbon dioxide poisoning and could be particularly dangerous for women who are pregnant.
Additionally, the sound of the engines and other noises in submarines can cause hearing damage as a result of prolonged exposure. As a result, many militaries don’t allow women to serve in submarines due to potential health risks.
Technology can also be a factor when discussing why women are not allowed in submarines. Many submarines don’t have accommodations for women to shower, use a bathroom, or change clothes, which can create a very uncomfortable environment for female sailors.
Additionally, submarines are typically very noisy, which can make it difficult for women to communicate effectively and participate in certain tasks.
In addition to concerns about health and technology, there are also social issues to consider when discussing why women are not allowed in submarines. In many cases, crowded quarters and limited personal space make it difficult to ensure an environment of respect and privacy.
Additionally, some submarines may not have enough beds to accommodate a larger crew. All of these factors together make it difficult for submariners – both male and female – to safely, comfortably, and respectfully coexist.
Are there showers on nuclear submarines?
Yes, there are showers on nuclear submarines. In order to conserve space on the submarine, the shower often doubles as a room to store equipment while not in use. Most naval submarines have limited hot-water capabilities, providing only enough hot water for one person to take a brief shower at a time.
Navy officials have also admitted that sometimes space for showering becomes an issue and may inhibit their ability to shower on a regular basis, especially when submarines remain submerged for extended periods of time.
To counteract this, crews may adopt a “rotating shower regimen” on the longer missions, in which each crewmember takes turns showering or a schedule is established to ensure that everyone gets a chance to clean up.
How long can a nuclear submarine go without surfacing?
Nuclear submarines have the capability to stay submerged for extended periods of time, sometimes even months. The exact amount of time that a nuclear submarine can remain underwater without surfacing depends on a few factors, such as the size of the submarine, the amount of food and supplies it carries, the nuclear fuel it carries, and the type of activity it is engaged in.
For example, a larger submarine with more supplies and a greater amount of nuclear fuel can stay underwater longer than a smaller one. Submarines can also stay underwater longer when they are engaged in low-intensity activities, such as surveillance and intelligence gathering.
However, in general, a nuclear submarine can stay submerged for up to six months at a time without surfacing. Even though the nuclear submarines have the capability to stay underwater for extensive periods of time, for the safety of the crew and the submarine, recharging of the batteries and restocking of supplies and food are necessary every three months or so.
Why are nuclear subs so quiet?
Nuclear submarines are designed to be incredibly quiet because they must be able to conduct covert operations while remaining undetected by sonar and other detection methods. In order to achieve this degree of stealth, the designers have included a number of features.
First, the vessel is constructed with quiet propulsion systems and advanced sound-proofing materials to reduce the transmission of noise from the environment. Additionally, the submarine utilizes a series of customized ballast tanks to reduce its flow resistance and help disperse any sound generated by the engines and the propellers.
To further reduce its acoustic signature, the submarine is coated in a special, anechoic rubber that helps absorb sound. Finally, the submarine’s propellers and other moving parts operate with a near silent, low-frequency range.
All of these features combined allow nuclear submarines to remain incredibly quiet and, consequently, undetected while on missions.
How do submarines stay cool?
Most submarines use a cooling system which, depending on the type of vessel, can vary slightly in design, but still functions the same way. Generally, the system uses an external sea water pump to bring in cold water from outside the submarine and direct it to a condenser.
This condenser is a single room-sized unit in which a high-pressure refrigerant is circulated, transferring heat from the submarine’s atmosphere to the relatively cool external water. The water then leaves the condenser, heated, and is released at the rear of the submarine.
Additionally, most modern submarines also include an air-conditioning system, which typically consists of two or more air conditioning systems which filter and dehumidify the air on board, helping maintain a comfortable atmosphere inside the submarine.
