US Cartridge, 105mm APFSDS-T, M735, M735E1, M735E2, XM735E2
This cartridge is a high velocity, flat trajectory, discarding sabot round used in 105mm gun cannons against armored targets.
The projectile consists of a subprojectile and sabot. The sub subprojectile consists of a steel nickel body, which houses a tungsten core and is fitted with an aluminum windshield and fin assembly. The aluminum sabot, composed of’ three 120 degree sections, is assembled around the subprojectile. A steel hourrelet, containing three shear cuts, is screwed to the sabot forward face. A nylon obturator and polypropylene seal is assembled around the sabot, and a urethane seal is applied over the rear face of the sabot. An M13 tracer is assembled in the fin and held in place by a threaded plug and disc assembly. The projectile is crimped to an M148A1B1 cartridge case, which holds approximately 12.5 lb of M30 propellant, and is fitted with an M120 electric primer. A gun tube wear reducing titanium-dioxide liner is assembled to the interior wall of the cartridge case.
