EDITORS COMMENTS
This photograph showcases a print from the Illustrated London News, dated 1946, featuring acoustic torpedoes, a groundbreaking innovation in underwater weaponry during the Second World War. The caption reads, "Off the secret list: torpedoes which hunt their prey by ear, and leave no telltale bubble track." During the First World War, torpedoes, often referred to as "tin fish," relied on a simple design that followed a predetermined course and left a visible bubble trail as they swam through the water. These torpedoes were notoriously inaccurate and predictable, making them an unreliable weapon against enemy ships. However, the advent of acoustic and electric devices transformed the torpedo into a much deadlier weapon. Acoustic torpedoes, as depicted in the illustrative drawings, utilized sound waves to detect and home in on their targets. By emitting and receiving underwater sounds, these torpedoes could accurately track and destroy enemy ships, leaving no bubble trail to give away their position. The electric components of the torpedo allowed for the use of a homing device, which could be activated upon detection of the enemy ship's magnetic field. This feature enabled the torpedo to self-guide towards its target, increasing its chances of a successful hit. The cross-section drawing of the torpedo provides a glimpse into the intricate technology that made these weapons so effective. The combination of acoustic and electric devices revolutionized underwater warfare and played a significant role in the outcome of the Second World War. This photograph serves as a testament to the remarkable advancements in science and technology during the 1940s.
