Most modern combat Navy surface vessels have Anti-Submarine Warfare (ASW) sonar arrays of some type, and at least 1 Aircraft Carrier does as well (newer carriers use their escort vessels for ASW sonar screens).
Essentially, that comes down to Cruisers, Destroyers, and Frigates, which make up the bulk of a Carrier Battle Group or Task Force screen to protect the Carrier from submarine threats.
However, those ships, as well as Carriers, also use fixed and rotary wing aircraft with deployable (dipping) and expendable (sonobuoys) sonar as well.
Ship sonar systems include the main forward sonar arrays, as well as deployable Variable Depth Sonar (VDS) towed sonar systems.

How does the information gathered by ships using Sea Beam sonar differ from that collected with standard methods that use one sonar device?
A sonar uses one device and a sea beam uses a dozen sonar devices.
What are the differences between side scan sonar multi-beam sonar?
Side scan sonar uses sonar to map the the ground below by emitting continuous sonar pulses while moving. The sound continuously reflects back to the system's receiver, which creates an image based on the energy of the signal received, where darker points in the image match things protruding from the ground and lighter spots indicate where there is nothing. It does not measure the depth. Side scan sonar is usually towed behind the vessel using it. Multibeam sonar is similar to side scan sonar, except that it is attached to the vessel (rather than being towed) and measures the time difference between sound emission and reception, rather than the energy of the incoming sound waves. Thus, it measures depth instead of making a picture.
How do scientists make maps of the ocean floor?
Sonar
What was the effect of north Vietnam torpedoing the us navy ship?
There was no visual or physical evidence of torpedo attacks, although objects were picked up on the ships sonar. In any event, Congress approved the Gulf of Tonkin Resolution, which began Americas involvement in the Vietnam War.
Does sonar uses sound waves to measure water depth?
Yes. Active sonar generates a pulse, the echo is heard some time later. The time it takes for sound to travel from the generator to the reflector and back to the sensor discloses the distance from the sonar equipment to the object reflecting the sound waves. Passive sonar just listens and does not generate any sound pulses itself but through various analysis algorithms certain information about the distance to an object that does make sound can be obtained. Passive sonar is not used for finding the depth of water but for listening to ships.
Can you give an example of SONAR?
A sonar is Fitted into a ship to detect how deep the water is
How does a ship find its location?
Sonar
What is the explanation for the working and principal of sonar?
sonar consist of a transmitter and a data and it is installed in a boat or a ship
How do you use sonar in a sentence?
Scuba Divers use a Sonar to find treasure or a hidden ship.
What is included in the product group Sonar Systems?
airborne, surface ship, and submarine-based sonar systems including depth-finding equipment, guidance hydrophones, sonabuoys, sonar fish finders, navigation and mapping sonar, and anti-submarine sonar equipment
German research ship that studied the ocean durinning the 1920s?
sonar
What would be useful in locating a sunken ship at the bottom of the ocean?
Sonar
How do submarines detect enemy ship at sea?
By an electronic device called 'sonar' .
What are the applications for sonar?
A)to find the depth of the sea b)the sonar device measures the time taken by the ultrasonic sound to travel from the ship to the bottom of the sea .
What is depth of the ocean if a sonar signal takes 4 seconds to travel from a ship to the ocean floor and back?
Unfortunately the ship sank
What is the differences of an active sonar and passive sonar?
Active sonar sends a signal out from a source and when it encounters an object the signal reflects back to the source. This can be detected by the object it is reflecting off of like a ship or submarine. Passive sonar is simply putting a microphone in the water and listening. It is also undectable.
Who was the first person to use sonar in the navy?
Most likely it was some unknown bosun's mate that worked in the sonar lab at the Navy Bureau of Ordinance.
