Those who are looking for an answer to the question «Why are submarines made of a high alloy steel?» often ask the following questions:
🌊 How can submarines detect other submarines under water?
The main method is through listening using passive Sonar. Active sonar sends out a sound signal that can be used to bounce off the enemy. It may also give away their own position.
🌊 Are submarines aerodynamic?
They aren't designed aerodynamically, they are designed hydrodynamically. And the design they have is the way it is because it is hydrodynamic. However, there are greater considerations than speed, such as stealth and interior space efficiency (as you mention).

🌊 Are submarines streamlined?
Absolutely - the modern submarine's teardrop shaped hull is a direct result of R&D that eventually led to the design that virtually all modern submarines use today.Cigar shaped hulls are also used, but like the teardrop hull, they also taper to some extent at the aft portion of the hull, in the Engineering spaces. This is to provide better water flow over the aft control surfaces (rudder and stabilizers). Submarines travel underwater much the same as airplanes do in air, and it is no coincidence they have similar hull shapes.The result of the modern submarine hull shape allows it to go much faster underwater than it can on the surface (a lot faster). In the past (WWII, e.g.) submarines were essentially surface vessels that had a limited submergence capability, and as such, they were designed to run much faster on the surface than underwater. With the advent of Nuclear Power and hull design changes, the submarine was transformed into a weapons system that could quickly gain the tactical advantage over surface vessels by being able capitalize on the speed given by the hull design.

Submarines have to be very strong because when they are deep under water, there is a great deal of pressure exerted on them by the water. A hollow container underwater is not like a fish underwater, since the fish's body is filled with fluids (blood or other bodily fluids) that are no more compressible than the surrounding water is. Air behaves differently, it is compressible, so the hull must be strong.

Do submarines fly underwater?
Aircraft use lift from their wings to stay aloft, while submarines operate like underwater balloons, adjusting their buoyancy to sink or rise… “Submarines cannot fly,” he says, “but seaplanes can submerge.” This was the thinking behind what was probably the first stab at a flying submarine.
Do submarines have ac?
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… Submarines usually carry up to 75 personnel on board during its journey into the sea.
Do submarines have wifi?
Even when a submarine is on the surface, the crew's access to the internet is severely restricted. ALL naval vessels limit their electronic emissions (including transmissions by radio), to reduce the likelihood that their movements can be tracked, and this would be given even greater emphasis for a submarine.
Do submarines need gas?
No - all submarines, be it nuclear or diesel-electric, use diesel fuel, either for primary engines (DE) or backup generator (nuclear).
How dangerous are submarines?
The underwater environment is a dangerous one. Submarines face many perils of the deep. Even a small fire or gas leak inside a submerged submarine can have catastrophic consequences. A collision with another vessel or grounding may be much more serious for a submarine than for a surface ship.
How submarines go underwater?
What makes submarines float underwater?
- A submarine has huge ballasts tank , the air in them makes the submarine float and when it has to go underwater the ballasts tank is filled in with the sea water and when submarine has to come at the surface the water in the ballast tanks are pumped out.
How submarines see underwater?
- When on the surface, a sophisticated global positioning system (GPS) accurately determines latitude and longitude, but this system cannot work when the submarine is submerged. Underwater, the submarine uses inertial guidance systems (electric, mechanical) that keep track of the ship's motion from a fixed starting point by using gyroscopes.
How submarines stay underwater?
Buoyancy is controlled by the ballast tanks, which are found between the submarine's inner and outer hulls. A submarine resting on the surface has positive buoyancy, which means it is less dense than the water around it and will float. At this time, the ballast tanks are mainly full of air.
Ships float submarines sink?
Submarines can go downward because they flood their buoyancy tanks with water. This reduces the buoyancy of the sub, allowing it to go down. To rise again, the water is pumped out of these tanks.
When was submarines invented?
Where do submarines go?
in the water
Could submarines fire torpedos underwater?
Yes. The idea of the submarine is the element of surprise. Before nuclear power submarines ran on either battery power or diesel power. Every so often it needed to surface (or use a snorkle
- no kidding, it's called a snorkle) to run the diesel (which would both propel the sub and charge the battery) Now, with nuclear power, the submarine can stay underwater as long as there is food for the crew. A submarine nuclear reactor can last for years.
Did any nuclear submarines sink?
A number of nuclear submarines sank, and the circumstances vary from accident to accident. Wikipedia has a list, and by going there and entering "List of sunken nuclear submarines" you can review that list.
Do people float in submarines?
Do submarines damage the ocean?
Usually it sinks by itself, but some scrap metal can be added to aid its journey to the bottom of the ocean. Therefore, yes, submarines do produce trash that is thrown out into the ocean and it is terrible.
Do submarines explore the atmosphere?
No submarines do not explore the atmosphere. atmosphere means air. Sub means under, Marine means water.
Do submarines use oxygen tanks?
Submarines typically use air tanks. Oxygen is very dangerous and very flammable. It's use is very limited on submarines for that reason.
How are submarines used today?
Submarines todaee are used for underwater exploration,funn,new life underwater.
How deep can submarines go?
A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world's oceans is 3,790 meters, or 12,400 feet, or 2 1⁄3 miles.
How do submarines communicate underwater?
U.S. Navy submarines use a specialized telephone system to communicate underwater. It works much like an AM radio, except that it transmits and receives sound waves instead of transmitting and receiving radio waves. Similar to land-based systems, underwater telephone systems use microphones and audio amplifiers.
How do submarines get air?
Atmosphere inside submarines is very carefully monitored and controlled… Oxygen in submarines is produced by putting sea water through a process of electrolysis. Submarines typically have a couple of big oxygen tanks as well, used to quickly raise oxygen concentration if the system fails.
