CAPABILITIES

Conventional 120mm Tank Ammunition

ATK's 120mm ammunition is the most advanced in the world. It is fully compatible with 120mm smooth bore weapons on M1A1 and M1A2 Abrams Main Battle Tanks and the Leopard 2 Main Battle Tanks with L44 and L55 smooth bore cannons.

The M829A3 defeats advanced armor at extended ranges. The M830A1, a multipurpose high explosive round, destroys armored vehicles, structures and helicopters. It is the only tank ammunition in the world with air burst capability that is effective in defeating air targets. ATK is the sole producer of these advanced rounds. The 120mm training ammunition designs provide low cost live fire training to the tank crew.

The M829A1 Kinetic Energy round was designed as a replacement for the M829 KE round. The M829A1 utilizes a redesigned projectile and improved propulsion system to increase on-target performance. The M829A1 is combat proven in Operation Desert Storm where the round became known as “The Silver Bullet.” Said one tank commander during the Gulf War, “The ammunition is…like a laser beam.”

This multipurpose round employs a shaped charge warhead to defeat both armor and “soft” targets. Full frontal activation makes the M830 effective on tanks with bar-type spoilers to counter HEAT projectiles. The activation turns the liner into a molten jet. When the jet strikes a target of armor plate, pressures in the range of hundreds of kilobars are produced at the point of contact. This pressure produces stresses far above the yield strength of steel, and the target material flows like a liquid out of the path of the jet (hydrodynamic penetration).

The M830A1 HEAT-MP-T was developed as a replacement for the M830 HEAT round. It has demonstrated a 20-percent performance increase against bunkers and a 30-percent performance increase against light armored vehicles. The M830A1 uses a discarding sabot with sub-caliber warhead and a multifunction fuzing system. It has a unique airburst capability that is quickly selectable by the tank crewman. The unique fuzing options and fast time of flight make this round the ultimate warhead in urban warfare. Know commonly as “MPAT,” it was the round of choice in operation IRAQI Freedom.

The M831A1 TP-T round replaced the M831 TP-T. It uses a patented design that provides a near ballistic match to the M830 service shot. The unique design provides a low cost HEAT trainer that makes live fire training much more affordable.

The short maximum range makes this round desirable for training exercises where range is limited.

The M865 TPCSDS-T uses a unique, patented conical fin to provide a flat and accurate trajectory for target ranges. After passing the target range, the projectile velocity drops off sharply to limit the maximum range to 8 km. This safety feature allows for use on U.S. and European ranges where permissible projectile travel is limited.

M908 HE-OR-T (High Explosive Obstacle Reduction) was developed to destroy obstacles and barriers (concrete, rock, dragon's teeth, etc.) set up to stop tanks.

The round is a modification of the M830A1 (MPAT) where the front fuze is replaced with a steel nose. This provides penetration into the obstacle before detonation. The M908 has demonstrated performance better than the 165mm M123A1 HEP.

Designed to be visually and ballistically similar to the M830A1 Tactical Round. Consistent performance across temperature ranges.

Low cost due to simplicity of design and automated manufacturing.

Incorporates simulated nose switch to enhance training realism. The M1002 (MPAT Trainer) uses a design that provides visual, weight and ballistic match to the M830A1 tactical round. The design incorporates a simulated nose switch to enhance the training experience while providing a low cost training round that makes training more affordable. Product Qualification to begin in 2002 with Low Rate Initial Production starting in 2004.
