Abstract: The invention relates to the field of penetrative projectiles capable of penetrating buildings whose structures are reinforced such as anti-aircraft shelters for example. The invention consists in a projectile comprising a solid penetrative body designed to perforate a wall of the building, the roof for example. Inside the projectile according to the invention are housed sub-munitions enclosing the charge in the form of bomblets, a device for plugging the hole formed in the wall by the passage of the projectile, and a sequencing and command device. When the wall is penetrated, the rear portion of the penetrative body is separated from the rest of the penetrative body and the plugging device is deployed so as to block the hole that has been passed through. After penetration, the front portion of the penetrative body continues its route toward the ground while the sub-munitions enclosing the bomblets remain suspended in the air under the wall.
