Spin-decay self-destruct fuze

A method for post-launch self-neutralizing a projectile having a fused warhead including a stab detonator and a launch-induced spin, the method comprising the steps of:

• a. providing in the projectile an electric power source, an electric power storage device, and an electric detonator, the providing step including the substep of locating the electric detonator sufficiently close to the stab detonator to initiate the stab detonator upon the initiation of the electric detonator;
• b. supplying power to the electric power storage device from the electric power source after launch;
• and
• c. applying power from the electric power storage device to the electric detonator immediately upon substantial decay of the projectile spin to initiate the electric detonator.

A fuzing apparatus for post-launch self-neutralization of a projectile having a launch-induced spin, said apparatus comprising:

• a stab detonator operable to detonate the projectile;
• an electric power source;
• an electric detonator positioned sufficiently close to the stab detonator to initiate the stab detonator upon initiation of said electric detonator;
• and
• a spin decay switch circuit operatively connected to both said power source and said electric detonator for immediately initiating said electric detonator upon substantial decay of the projectile spin, each of said power source, said spin decay switch circuit, and said electric detonator being configured for mounting in the projectile.
