Fuzing systems for projectiles
First Claim
1. A fuzing system for an explosive projectile comprising:
- fuze means adapted to be incorporated in the projectile and comprising a light-signal detector arranged to initiate the explosion upon receipt of a light-signal by the detector; and
means operable by a signal produced when firing the projectile for transmitting, at a time after firing the projectile related to the known velocity of the projectile and the predetermined range to a target, a said light-signal receivable by said detector so that said explosion occurs at least approximately when the projectile reaches the target.

Abstract
An explosive projectile, eg an anti-tank shell, is fitted with a light-sensitive fuze enabling it to be detonated by a laser pulse transmitted at a time after firing the projectile determined by the pre-determined range to the target and the known velocity of the projectile. The fuze is located in the base of the shell (in addition to the usual impact fuze) with the light-signal detector, eg a photo-diode, facing backwards. The detector is connected to the initiator via "fast" electronic circuitry so that the fuze is insensitive to "slow" or "DC" light signals such as the sun, searchlights etc. The laser beam is made slightly divergent to illuminate a suitable target area. The invention allows an anti-tank shell, normally loaded in the tank gun, to be used effectively against "soft" targets (troops, helicopters, etc) for which a direct hit is not necessary. The laser may be part of the gun range-finder system.
