Detailed explanation-1: -Detailed Solution. The technology that was developed to track enemy submarines in World War II was SONAR. This technique was first used by the Americans in World War II. SONAR stands for Sound Navigation and Ranging.

Detailed explanation-2: -Making Connections Between the Science and Technology of WWII and Today. Back on April 16, 1944, the sailors of the USS Joyce and USS Peterson used sonar to detect the position of U-550 and drop depth charges, severely damaging the submarine.

Detailed explanation-3: -14.12. 2 Active Sonar. The active sonar of surface vessels is normally used for detection, surveillance, tracking, and identification of submarines.

Detailed explanation-4: -Q. A SONAR (sound navigation and ranging) uses ultrasonic waves to detect and locate objects under water. In a submarine equipped with a SONAR the time delay between generation of a probe wave and the reception of its echo after reflection from an enemy submarine is found to be 77.0 s.

Detailed explanation-5: -The ASDIC, known to the Americans as Sonar, was basically a transmitter-receiver sending out a highly directional sound wave through the water. If the sound wave struck a submerged object it was reflected back and picked up by the receiver.
