Do submarines use radar or sonar
Passive sonar systems are used primarily to detect noise from marine objects (such as submarines or ships) and marine animals like whales.

Why do submarines not use radar
While radar can effectively move through or around various environmental conditions, it is much less effective underwater. The electromagnetic waves of radar are absorbed in large bodies of water within feet of transmission. Instead, we use Sonar in underwater applications.

Can US submarines be detected
If the sea is calm and the periscope is up long enough, a radar can pick it up. A diesel-electric submarine without AIP (Air Independent Propulsion) has to raise the snorkel to run the diesels and charge the batteries. The snorkeling submarines can be detected by radar if the waves are not too high.
When did US submarines get radar
The first prototype SJ was deployed in December 1941, but it was mid-1942 before they became common equipment. SJ radar was on all submarines by early 1943.
Do modern submarines have radar
Antenna masts and antenna-equipped periscopes can be raised to obtain navigational signals but in areas of heavy surveillance, only for a few seconds or minutes; current radar technology can detect even a slender periscope while submarine shadows may be plainly visible from the air.
How does a submarine see where it’s going
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.
Why is it so hard to detect a submarine
Salt water is mostly opaque to electromagnetic radiation, so subs are invisible to radar. Sonar can locate underwater objects, but modern submarines are built to be very quiet.
Can the US detect enemy submarines
Countries like the United States and China have built networks of hydroacoustic sensors, which use sonar technology to detect submarines that navigate close to their coastal borders and strategic military locations.

How does the US track submarines
Countries like the United States and China have built networks of hydroacoustic sensors, which use sonar technology to detect submarines that navigate close to their coastal borders and strategic military locations.
Can submarines avoid detection
And whales they must take action that usually involves turning the sonar down or off completely the way sound waves Bend determines. What can be picked up by sonar submariners can find places between
Do submarines have cameras to see
Underwater video cameras may be used by submarines for monitoring of systems such as towed-array sonars or dry deck shelters. They may also be used for periscoping.
How do submarines stay stealthy
SONAR offered submarines stealth. SONAR is a system that uses sound waves traveling through water to search for objects or geographic obstacles. There are two types of SONAR, passive and active. PASSIVE SONAR picks up sounds using electronic listening equipment.

Is there a no touch rule on submarines
Navy rules forbid any relationships between sailors in the same chain of command for fear it would lead to favouritism and undermine orders. Relationships outside the chain of command are allowed, but there is a strict “no touching” rule during deployments.
What is the thing on a submarine to see
Submarines have periscopes so that people inside can what is on the surface of the water. A periscope is a useful example of the law of reflection at work. It's important that your mirrors are placed at a 45° angle, because light always reflects away from a mirror at the same angle that it hits it.
Why can’t females be deployed on a submarine
Close contact between male and female crew members in confined spaces on board a submarine could have consequences that would degrade morale and readiness. Individual patrols can last as long as 70 days, and deployments can last six months.
Are there females on submarines
Enlisted women serve aboard four guided-missile submarines and one ballistic-missile submarine. There are 70 active submarines in the fleet.
How do submarines see without windows
Typically, submarines don't have windows and hence the crew cannot see outside. When a submarine is near the surface, it uses a periscope for a view of the outside. Most submarines travel much deeper than periscope depth and navigation is done with the help of computers.
Do they allow female Navy SEALs
Are women capable of becoming Navy SEALs Yes. Here are some of the qualifications that both men and women must pass in order to begin training. Be a U.S. Citizen and eligible for security clearance.
Who is the female captain of a submarine
In August, Master Chief Information Systems Technician (Submarine) Angela Koogler became the first woman to serve as a chief of the boat, the senior enlisted adviser to the commanding and executive officers.
Do submarines have showers
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.
Can you smoke on a submarine
While air scrubbers remove most of the smoke, there are still unacceptable levels of secondhand smoke in the atmospheres of submerged submarines, according to the Navy study that led to the ban. Crouse remembers when thick smoke was acceptable.
Why do Russian subs have windows
But Russian submarines have long transit times, and the harsh weather conditions that they encounter, especially in the Barent Sea, demand the personnel. to stay in the enclosed space of the sail, which is why windows are needed.
How much do Navy SEALs get paid
How much does a Navy Seal make As of Jun 5, 2023, the average annual pay for a Navy Seal in the United States is $43,685 a year.
