The earliest use of Submarine Sonar was by the British Royal Navy. In 1915, 10 British H class submarines were equipped with the first passive sonar system, known as a Fessenden Oscillator. The FO was able to detect a target, but could not establish a bearing, which is critical to target tracking. Further research into Hydrophone and Transducer technology eventually led to active and passive sonar systems, though those old systems were extremely basic by today's modern sonar standards.
However, little has changed except for the bells and whistles on modern systems. Submarine Sonar, like then, still use Transducers and Hydrophones for operation. The only thing that has changed is how the information is processed and displayed to the operator.
The Oceans haven't changed much either.

What is used to locate submarines?
sonar hydrophones
When was sonar first used and by whom?
Sonar was first used during World War I by the British Royal Navy. It was used to detect submarines by emitting sound waves and analyzing the echoes that bounced back.
What is one event where sonar was used in World War 2?
Sonar was used to detect and hunt submarines in WW2
What is sonar technology used for?
It is used for detecting submarines under water.
What is a sonar used for?
Sonar is used to detect other vessels or ships/submarines through a tube-like device> Andrea
When was the first sonar invented?
In 1915, Paul Langévin invented the first sonar type device for detecting submarines called an "echo location to detect submarines" using the piezoelectric properties of the quartz.
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 the name of an early form of sonar used for locating submarines?
The answer is ASDIC
How were sonar systems used in World War 2?
They were used by submarines to navigate when not in open waters, They were also used by submarines and anti-submarine ships to locate enemy submarines.
How do submarines navigate?
Sonar
Who used sonar first?
The first documented use of sonar was during World War I by the British Royal Navy to detect submarines. The technology was further developed during World War II for anti-submarine warfare.
How did sonar help in World War 2?
Sonar was used widely in World War II in an effort to locate enemy submarines. It wasn't as sophisticated as it is today, but it did help. Actual numbers are difficult to come by, but sonar was effective in the successful attacks on several submarines.
