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.

What was used in WW1 to detect submarines?

During World War I, several methods were employed to detect submarines, including hydrophones (underwater microphones) and sonar technology, which were still in their early stages of development. Ships also used depth charges and patrolling aircraft to locate and attack submarines. Additionally, the use of smoke screens and listening devices on ships helped in identifying submarine positions. These technological advancements marked the beginning of more sophisticated anti-submarine warfare strategies.


Why do submarines use echolocation?

Submarines use echolocation to detect, locate, and avoid obstacles underwater, as well as to navigate their surroundings. By emitting sound waves and analyzing the echoes that bounce off objects, submarines can map their environment in conditions where visual navigation is limited or impossible.

What instrument was used during World War 1 to detect the sound of submarines?

During World War I, the primary instrument used to detect the sound of submarines was the hydrophone. This underwater listening device allowed ships to detect the noises made by submarines, such as engine sounds and propeller movements. Hydrophones were often deployed in arrays and played a crucial role in anti-submarine warfare, helping to locate and track enemy submarines.

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 does submarines use echoes?

Submarines use echoes through a technique called sonar (Sound Navigation and Ranging). They emit sound waves that travel through water, bounce off objects or the seafloor, and return to the submarine. By analyzing the time it takes for the echoes to return and the characteristics of the sound, submarines can detect and locate other vessels, underwater obstacles, and map the ocean floor. This capability is crucial for navigation, surveillance, and tactical operations while remaining stealthy underwater.
