Abstract

A fuse is capable of installation in a warhead only when a rotor of the fuse is in its safety position. If the rotor is in its live position, installation in the fuse is not possible. The fuse comprises an installation safety element which is movable between a normal first position blocking installation of the fuse and a second position permitting such installation. In its live position, the rotor blocks movement of the element to its second position. When in its second position, the element does not interfere with movement of the rotor to a live position.
