Mark VII Heavy " This had a 150 lbs. (68 kg) cast-iron weight attached to increase the sinking rate. The British claimed this DC would split a 0.875 inch (22 mm) hull at 20 feet (6.1 m) and force a submarine to surface at about twice that distance. A minol charge introduced in 1942 increased these distances to 26 feet (7.9 m) and 52 feet (15.8 m), respectively "

Sink Rate / Terminal Velocity 16.8 fps (5.1 mps)
Settings 300 feet (91 m) max

The deepest DC setting was the US Mark 16 " Postwar DC for projector use, only. Mod 0 was hydrostatic, Mod 1 was acoustic. Last DC developed for the USN
