During WWII, Allied warships used ASDIC (an early, crude form of Sonar), airplanes (some ships carried recoverable seaplanes), and visual lookouts (binoculars) to spot submarines and direct attacking vessels to the contact.

How were World War I submarines used?
World War I submarines were primarily used to locate and attack surface cargo and warships.
What is used to locate submarines?
sonar hydrophones
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.
Form of sonar used to detect and locate enemy submarines by means of ultrasonic waves?
Type your answer here... ASDIC
Who allowed allied ships to locate German U-boats on the surface of the water at night?
US PBYs and escort carriers were able to locate and destroy enemy subs in the Atlantic.
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.
How do you turn off auto attack on World of Warcraft?
Firstly locate the auto-attack feature in your Spellbook. It should be in the General section. Go into combat with a creature and find the auto-attack button in your book. If it is flashing red that means auto attack is on and you need to press it to turn it off.
How do snakeheads attack people?
They use their senses to locate where you are, and violently bite you on the back like it would treat a prey. A snakehead can also kill you.
What is the technique used by submarines to locate their enemies?
They use sonar to find the enemy. Passively, they listen for the sounds of the other ships, which will give them a bearing to the target. Active sonar will ping the enemy and provide a range as well.
What are the uses of echolocation?
Dolphins use echolocation to communicate with each other. Bats use it so they dont fly into things like trees. Boats and submarines use it to locate where each other are so they can fire bombs at one another.
Can sonar transmitters locate submarines?
In the early days of ASW, active sonar was used quite a bit for trying to locate submarines; however, today active sonar is primarily used only by aircraft, in the form of helicopter dipping sonar. Ships do use active sonar, but modern nuclear submarines are extremely adept at using the ocean environment to their advantage in avoiding active transmissions. The main disadvantage to using active sonar is that a ship automatically gives away their position; this wasn't as big a problem with older boats which used "John Wayne" style torpedoes that required you to be in visual range of a target, meaning you were exposed during an attack. Modern boats use passive sonar tracking, and use torpedoes that can be fired thousands of yards away,without ever getting near a target. Modern torpedoes have their own sonar tracking systems that are extremely difficult to evade once they acquire a target. Modern submarines' speed and depth capability also means that they can egress an area where active sonar is being used very quickly, or avoid it altogether as it can be detected miles away before a boat ever gets in range of the transmitting sonar. Active sonar is used by ships to find diesel-electric submarines that are running on the battery, though. Such boats are extremely difficult to detect, even by other submarines at close range. In many cases, active sonar is about the only way to find and track them, but unlike nuclear submarines, once a DE boat is located, they're pretty much history. They don't have the speed and depth capability that nukes do to egress an area if they're caught, but they can still use the ocean environment to their advantage if the sound conditions are in their favor.
What was the japanese's plan for the attack on pearl harbor?
They had anticipated that all U.S. War ships were in the harbor (most war ships were out in the ocean and the location was not known to the Japanese) and the mission by the Japanese was unsuccessful as far as they were concerned. They quoted, "We have woken up a sleeping dragon" meaning the U.S. was still powerful enough to retaliate.
