Abstract

The protection system includes a location apparatus ascertains the position of an intruding body (18). A firing unit directable to a point on the track of the body comprises a mine (M) with directable operation. Its operating direction is adjustable in dependence on a signal from the device (16), due to a support holder. Pref. the support holder is pivotally borne on a universal joint. A control device in the ascertaining device may predict the path of the body, esp. of a flying body, to direct the or each mine. Pref. plural mines are controlled, and the mines may have projectile charges. The explosion of mines may be caused when the distance sums to those mines fall below a set value, or reach a minimum. The mines may be ballistic devices. @(8pp Dwg.No.4/7)@
