ABSTRACT:
A cased telescoped ammunition round 10 for a fin stabilized penetrator 32. A full caliber control tube 24 is positioned within casing 12, its forward end 28 being secured to front seal 22. The side walls 87 of control tube 24 are tapered, increasing in thickness from the free standing aft end 26 of control tube 24 to its forward end 28. Penetrator 32 and sabot 36 are positioned within control tube 24 with obturator band 46 and retaining groove 36 of aft bourrelet 36 positioned within control tube 24. Retaining groove 52 at the aft end of control tube 24 with split ring 50 and retaining groove 48 of aft bourrelet 36 retain sabot 34 and penetrator 32 within control tube 24 until round 10 is fired. Tapered side walls 87 minimize the volume of control tube 24 while assuring that side walls 87 are strong enough to withstand forces acting on control tube 24 forward of obturator band 46 when round 10 is fired.
