![]() The E3 round will provide the M1A1 and M1A2 Abrams tanks with greater armor penetration capability than previous generation depleted uranium penetrator rounds, while increasing accuracy. Although its armor penetration performance is classified, this round is considered as the most powerful anti-armor ammunition in the world. ![]() It will replace the M829A1 and the M829A2 projectiles. The 120mm APFSDS-T M829E3 is the third generation of depleted uranium armor penetrator tank rounds. Estimated penetration performance: 750 mm at 2,000 meters. Combined, these features increase the muzzle velocity of the M829A2 approximately 100 m/sec greater than the M829A1 (up to something around 1,776 m/sec), while operating at slightly lower pressure. These include the use of a special manufacturing process to improve the structural quality of the depleted uranium penetrator, plus the use of new composites for the sabot, which, together with a new propellant, provide superior penetrator performance. The new ammunition's performance gains, while classified, result from several new features. It is a technology improvement over the M829A1, the "Silver Bullet" of Desert Storm fame. The next generation ammunition, called 120mm APFSDS-T M829A2, entered service in 1994, and is the current armor penetrator ammunition being produced by by the General Dynamics Ordnance and Tactical Systems for the 120mm M256 gun of tanks M1A1 and M1A2.
