ABSTRACT:
A telescoped ammunition round comprises: a propellant charge having an axial cavity for supplying firing power for the ammunition round; a projectile housed within the axial cavity for being fired from a forward end of the ammunition round; a control tube means housed within the axial cavity for selectively covering an aft surface portion of the propellant charge axial cavity, the control tube means having a generally cylindrical axial bore substantially coaxial with the axial cavity, the projectile extending forward of the control tube means; coupling means for releasably securing the projectile to the control tube means; a control tube pistion having a generally cylindrical outer shape forming a sliding fit within the axial bore, positioned aft of the projectile; a booster charge within the axial bore, the control tube piston being forwardly movable in response to the firing of the booster charge and the projectile, in turn, being forwardly movable by forward movement of the control tube piston; a primer means in communication with the booster charge for actuating a firing sequence for the ammunition round; and projectile guide means for guiding the projectile during forward movement thereof from the axial cavity to a gun barrel upon firing the ammunition round, comprising a generally circular disk mounted in a forward position within the ammunition round substantially normal to the longitudinal axis thereof and concentric with the projectile, the disk comprising segmenting means for segmenting the disk into a plurality of generally triangular petals resiliently forwardly deflectable from the center of the disk to apply radially centering pressure upon the projectile during forward movement thereof.
