Abstract

The invention relates to a mine with at least one ejectable sub-munitions body disposed in a cup-shaped starting device and with a propulsion device for propelling the sub-munitions body into a selectable altitude range. For achieving that the propulsion device requires only a small structural volume, entails low cost because of the use of reduced amounts of propulsion charges and in addition operates safely and dependably. It has been proposed to dispose the propulsion device not in or on the sub-munitions body, but in the bottom part of the cup-shaped starting device. In this case the propulsion device advantageously consists of a high pressure chamber facing the bottom of the starting device, in which the propellant charge is contained, and of a low pressure chamber facing the sub-munitions body. The high pressure and low pressure chambers are separated from each other by a perforated plate provided with jets (holes).
