Modern naval ships use some form of Sonar to detect submarines. Additionally, some ships are equipped with Magnetic Anomaly Detectors (MAD gear) that detect a submarine's impact on the Earth's magnetic field in that area. The gear is typically carried aboard helicopters temporarily stationed on the ship.

Why is water a good medium for communication between dolphins?
Sound waves travel very well in water. Warships, including submarines, use passive sonar to listen for enemy ships and submarines. Passive sonar employes underwater hydrophones to listen for sounds. They can detect sounds of ships and submarines miles away. Marine mamals such as whales and dolphins detect sound in much the same way.
Can sonar use in periscope depth?
Yes sonar can be used at periscope depth. Surface ships also have sonar arrays on them. They are usually used to detect submarines.
What is a submarines use?
Sinking ships; exploring the depths.
What is a sonar used for?
Sonar is used to detect other vessels or ships/submarines through a tube-like device> Andrea
Why did they use the subs in war?
To sink enemy vessels, ships or submarines.
What did Germany use submarines for?
sink allied supply ships to England
Compare submarines and ships?
Ships try to avoid sinking, submarines sink on purpose...
How do submarines keep from running into objects?
they use sonar like bats do to detect objects that are in their path
Why do aeroplanes and ships use different types of compasses?
They don't - all aircraft, ships, and submarines use both magnetic, gyro, radio, visual, and satellite navigation systems. Ships and submarines also use dead reckoning plots and land based navigational aids for fixes (close to shore) for navigating.
Who benefits from submarines?
the military and navy use it for war and combat. Many submarines are made for launching missels and taking down ships and other subs.
How are oceanographic maps constructed?
They are mapped by sonar. The same technology they use to detect submarines from battleships / carriers.
The reason submarines can detect other underwater objects is largely due to which?
Submarines have sonars.
