Abstract
A submunition has a metallic body 1 a sensor 4 for sensing the presence of metal and an extendable probe (e.g. a spring 3) separating the sensor 4 and body 1 to avoid interference with the sensor. A circuit including the metal sensor and an impact sensor detonates the submunition if impact with a metal body is detected; if impact only is detected the submunition adopts the role of a mine.
Claims15
A submunition having:
- a fuzing arrangement including, a first sensor means, having a sensing element and responsive to the presence of metal to produce a first signal, second sensor means having an impact sensing element and responsive to impact to produce a second signal, third sensor means responsive to a stimulus to produce a third signal, actuating means responsive to the production of the first and second signals at the same time to produce a warhead actuating signal, and to the production of a said signal only by a preselected one of the first and second sensor means to actuate the third sensor means;
- a body comprising material which affects the operation of the sensing element;
- and a member extendable from the body to support the sensing element and an impact sensing element of the first and second sensor means respectively at a preselected distance from the body to reduce the affect of the said material on the sensing element and to sense impact with a metallic target at the preselected distance from the body.
