Nomenclature: Mark 6 (depth fuze) and Mark 8 (magnetic influence) "Ashcan" Weight: 345 pounds Charge: 300 pounds of TNT Sinking Speed: 8 - 12 feet/second. Depth: 30 - 300 feet (91 meters) Nomenclature: Mark 7 (depth fuze) "Ashcan" Weight: 645 pounds Charge: 600 pounds of TNT Sinking Speed: 8 - 12 feet/second. Depth: 30 - 300 feet (91 meters) Mark 9 (depth fuze) and Mark 14 (magnetic influence) "Fast sinkers": These were the later type of depth charges and had an aerodynamic shape, and a lead-weighted nose to increase their sink rate. Weight: Approximately 450 pounds Charge: 200 pounds of Torpex or HBX Sinking Speed: 14.5 - 22.7 feet/second. Depth: 30 - 1000 feet. (304 meters) The Mark 14 could explode at any depth. Found this in Wikipedia: "When a depth charge explodes it can take 15 minutes before the disturbance can settle down enough that sonar becomes effective. Many a submarine escaped during that time after an unsuccessful depth charge attack." Is that true?
