Combination fuze for missiles

A combination fuze for missiles for launching towards a target, comprising a current generator which is driven by a ram air operated means which has ram air supplied thereto through an inlet in the nose portion of the missile and which supplies electric energy to an electric firing circuit comprising an electric detonator and means which are adapted via the electric detonator to detonate the missile before it comes in physical contact with the target, and a mechanical percussion switch which is adapted to cause detonation of the missile upon impact of the missile on the target, wherein

• the mechanicl percussion switch comprises a sting sensitive detonator including a pyrotechnical delay and being equipped with a metal foil, and a firing needle which is included in the electric firing circuit, these parts being adapted for relative movement between the firing needle and the sting sensitive detonator upon impact which induces a circuit configuration of the firing circuit that triggers the electric detonator,
• an easily detachable nose jacket so adapted that when attached to the nose portion of the missile it completely or partly inactivates the electric firing circuit,
• so that the fuze when having attached thereto a jacket which prevents the supply of ram air to the ram air operated means, functions as a percussion fuze with mechanical firing of the sting sensitive detonator, and
• so that the fuze when having attached thereto a jacket which permits ram air to drive the ram air operated means for the supply of electric energy to the electric firing circuit, but which disconnects the proximity functions of the fuze, functions as a percussion fuze with electric firing of the electric detonator, and
• so that the fuze when having no jacket functions as a proximity fuze having a first electric percussion function and a second mechanical percussion function as further security for firing.
