Alberich - U-Boat's Revolutionary Anti-Sonar Tiles

Long before the era of modern stealth, Nazi Germany's Kriegsmarine developed a revolutionary technology to make its U-boats invisible to Allied sonar: Alberich anechoic tiles. This military documentary provides a deep dive into the first-ever wartime application of sonar-absorbent material on submarines, a concept that remains a standard feature on all modern naval submarines today.
We explore the sophisticated engineering behind these 4mm rubber tiles, which contained gas-filled voids designed to dampen and scatter active sonar pulses, effectively reducing a U-boat's detection range by a critical kilometer. Learn how this innovation gave German U-boats a fighting chance against the formidable Allied Hunter-Killer groups. We also examine the system's flaws, including the tendency for the tiles to peel off at high speeds, a critical weakness in this otherwise groundbreaking technology.
