THE RM MINES |
The RMD MINE. The RMD, figure 111, was designed for use as a controlled and/or in-fluence firing mine. Its construction began at the end of 1944 and continued until March, 1945. During this period only five shells were completed, none of which were shipped from the plant. |

Shortly before the end of the war in Europe, several improved models were completed and sent to SVK in Kiel for experimentation. This mine was not used operationally. It was designed for use with all the units fitted in the LMB mine. Section A of the mine housed the detonator, booster, and main charge; section B housed the firing unit. The outer end of section B was covered by an LMB type AA2 or type 4 DM-I tail door. |
The mine assembly is semi-cylindrical with flattened sides, and consists of three main parts: |
1. Base plate with launching wheels made of concrete |
2. Charge container with booster made of sheet aluminum |
3. Unit compartment of aluminum housed in a pressed paper section |
