THE RM MINES |
RMH Used as an Influence Mine. When the mine is launched, it is oriented by a can-vas drogue descent. Water pressure operates the booster-release mechanism and, at a depth of 15 feet, depresses the clock spindle, starting the clock. The clock runs off its delay setting, and the firing unit begins its arming cycle. |
No self-disarming device were fitted. |
