ABSTRACT:
An armor-penetrating ammunition assembly is provided with a multiple segment aluminum protective cap 26. The cap 26 is provided with a plurality of stiffening ribs 34, 34', 35, 35', and torque resisting tabs 40, 40' which rest in one of the grooves 37, 37' defined by the ribs 34, 34'. Additional stiffening is provided by rolled stiffening portions 36, 36' at the trailing end 32 of cap 28 and by longitudinal ribs 38, 38' at the longitudinal edges of each segment 28, 28' of the cap 26. Attachment structure is provided for forming a fixed interconnection between each segment 28, 28' of the cap 26 and a corresponding portion 19, 19' of the sabot 18. Thus, each segment 28, 28' of the cap 26 remains attached to a corresponding sabot portion 19, 19' as each portion 19, 19' of the sabot 18 separates from the penetrator 12 at muzzle exit without disturbing the flight of the penetrator 12.
