MAS Bulletin. DM 109 Underwater Acoustic Signal

Abstract

The DM 109 consists of an explosive charge and detonating fuse. The fuse has pyrotechnic delay and hydrostatic switch built in. Handling of the DM 109 is similar to the handling of a conventional hand grenade. When the safety pin is pulled and the DM 109 is thrown overboard, the spring-loaded safety lever is thrown and the device is armed. As the DM 109 reaches a water depth of between 3 and 6 meters, the hydrostatic switch operates and commences the detonation sequence, and the grenade explodes at a depth of 7 to 10 meters.
