Royal Navy depth charge with launcher Thornycroft.
Demilitarized.
In good condition.
The Royal Navy Type D depth charge was designated the "Mark VII" in 1939.
Initial sinking speed was 7 ft/s (2.1 m/s) with a terminal velocity of 9.9 ft/s (3.0 m/s) at a depth of 250 ft (76 m) if rolled off the stern, or upon water contact from a depth charge thrower.
Cast iron weights of 150 lb (68 kg) were attached to the Mark VII at the end of 1940 to increase sinking velocity to 16.8 ft/s (5.1 m/s).
New hydrostatic pistols increased the maximum detonation depth to 900 ft (270 m).
