Door breaching projectile

A door breaching projectile comprising:

• a shell containing an explosive charge;
• an open end of the shell with a mouth being connected to a rear edge of a body member;
• a hollow ogive with a mouth being connected to a forward edge of a body member;
• a safe-and-arm mechanism disposed in the body member, which safe-and-arm mechanism delays alignment of a detonator pin with a detonator charge only after the door breaching projectile has been propelled over a safe distance from an associated launcher and has spin rotated through predetermined numbers of spin;
• a sleeve disposed to slide in a seat member, with the seat member being mounted on a forward face associated with the forward edge of the body member;
• and
• a hollow guide member extending from an inside surface near a forward end of the hollow ogive, with the hollow guide member being aligned with the sleeve;
• wherein, upon the door breaching projectile impacting on a door or barricade, the sleeve is forced into the seat member to impinge onto the detonator pin, which then sets off the detonator charge and explosive charge, such that explosive shock waves cause the door/barricade to cave in but the projectile remains substantially outside the door/barricade.

A method for breaching a door or barricade from a distance comprising:

• launching a projectile from a grenade launcher to impact on the door/barricade;
• after the projectile is armed, delay rotating a safe-and-arm mechanism so that a detonator charge is aligned with a detonator pin fitted in a seat member, with the seat member being mounted on a forward face of a body member;
• and
• wherein, upon the projectile impacting on the door/barricade, impact force on the door/barricade impinges on the detonator pin to set off both the detonator charge and an explosive charge disposed aft of the body member, so that explosive shock waves cause the door/barricade to cave in whilst the projectile remains substantially outside the door/barricade.

A door breaching projectile comprising:

• a shell containing an explosive charge;
• an open end of the shell with a mouth being connected to a rear edge of a body member;
• a hollow ogive with a mouth being connected to a forward edge of a body member;
• a seat member mounted on a forward face associated with the forward edge of the body member;
• a detonator pin being fitted near a centre of the seat member;
• and
• a spring urging an assembly of a safe-and-arm mechanism into the body member;
• wherein the safe-and-arm mechanism delays alignment of the detonator pin with a detonator charge disposed in the safe-and-arm mechanism only after the door breaching projectile has been propelled over a safe distance from an associated launcher and has spin rotated through predetermined number of spin, so that, upon the door breaching projectile impacting on a door or barricade, the assembly of the safe-and-arm mechanism slides forward, resulting in the detonator pin impinging on the detonator charge and, in turn, setting off the explosive charge, such that explosive shock waves cause the door or barricade to cave in but the projectile remains substantially outside the door or barricade.
