| Description: |
|---|
| The M900 is a U.S. designed and developed 105mm APFSDS-T cartridge. The complete round contains a propulsion system consisting of an M148A1B1 steel cartridge case, an M43 LOVA propellant, an M128 primer, and a gun tube wear-reducing titanium dioxide liner which is assembled to the interior wall of the cartridge case. The projectile portion of the round consists of a subprojectile and a sabot. The subprojectile is made up of monolithic depleted uranium core, which is fitted with an aluminum windshield, a steel tip, and an aluminum fin assembly. The sabot is comprised of three 120° aluminum sections which are assembled around the subprojectile. A steel bourrelet, containing three shear cuts, is screwed to the sabot forward face. A nylon obturator and polypropylene seal is assembled around the sabot, and a silicone rubber seal is applied over the rear face of the sabot. An M13 tracer is assembled to the fin and is held in place by a threaded plug and disc assembly. |
| Use: |
|---|
| This is a kinetic energy, armor-piercing antitank round intended for use with the 105mm, M68 series gun mounted on M1 tanks only. |
| Functioning: |
|---|
| The M900 is loaded and fired from the M68 series, 105mm gun in the normal manner. Initiation of the electric primer ignites the propelling charge generating gases which drive the projectile from the gun and ignite the tracer. The silicone seal at the rear of the sabot prevents gas leakage between the sabot segments and the driving forces (gas) propelling the subprojectile downbore. Upon leaving the gun, aerodynamic forces cause the sabot to separate from the subprojectile allowing the subprojectile to continue on a true course to target while the sabot segments fall quickly to earth. Target penetration is effected strictly by the high kinetic energy of the subprojectile impacting the target. |
