A projectile (10) includes an ogive (30) at a forward end and a projectile body (20) removably coupled to an aft end of the ogive. A signal dye (14) or a filler material (132) is located within a first cavity (56) in the projectile (10), wherein the first cavity (56) is at least partially located within the ogive (30). A pyrophoric material (12) is also located within the first cavity (56), wherein the pyrophoric material (12) is hermetically sealed either within or by the first cavity (56).
F42B 8/16 - Projectiles or missiles disintegrating in flight or upon impact containing an inert filler in powder or granular form

F42B 12/74 - Projectiles, missiles or mines characterised by the warhead, the intended effect, or the material characterised by the material of the core or solid body
An escapement fuze self-destruct mechanism for a projectile includes a drive weight that maintains a biasing member in a compressed state by centrifugal force when a projectile's RPM speed is above a preselected threshold. When the RPM speed falls below the preselected threshold, the biasing member exerts sufficient counter-rotational force to overcome the centrifugal force exerted by the drive weight. The biasing member expands to an uncompressed state and displaces the drive weight into position for mechanically implementing self-destruction of the projectile if a rotor is fully armed or for rendering the projectile 'safe' if the rotor is in any position other then fully armed.
A command and arm apparatus includes a housing having a hollow interior. A pivotally-mounted rotor is disposed in the hollow interior. The rotor has a first, safe position of rotational adjustment that prevents detonation of an explosive and a second, armed position of rotational adjustment that enables detonation of an explosive. A locking cam is pivotally mounted to the rotor and has a rotor-locking position of repose. The rotor is free to rotate from its safe position to its armed position when the locking cam is rotated out of the rotor-locking position by a piston that extends from a piston actuator. The rotor abuts a flat formed in a sidewall of the housing and can rotate no further when the device is in the armed configuration.
