30mm Ammunition

​ATK provides the United States and its allies with a multi-service family of lightweight 30mm (LW30mm) ammunition. The ammunition was developed and fielded for the M230 chain gun on the AH-64 Apache helicopter. Combat proven in operations Just Cause and Desert Storm and in Afghanistan, LW30mm HEDP has demonstrated excellent armor penetration at ranges from 150 meters to 2,000 meters, effectively defeating the infantry-fighting vehicle threat.

Because of its light weight, small volume and moderate recoil, LW30 mm ammunition is ideal for helicopters, light ground vehicles (such as the HMMWV) and shipboard applications. Proven effective against light armor and materiel targets, it provides suppressive firepower at ranges equal to those of the Hellfire or TOW missile, making it the ammunition of choice for applications requiring both armor defeat and wide-area lethality.

ATK's LW30mm ammunition features a spin-compensated, shaped-charge liner, providing superior armor defeat plus additional growth potential. It also incorporates a high-performance, mechanical point-detonating fuze with impressive long-range performance and graze sensitivity. Outstanding armor penetration combined with blast concussion and fragmentation characteristics give the LW30mm ammunition superior multi-role, multi-target capabilities.

Our family of LW30mm ammunition consists of two rounds: M789 high-explosive dual purpose and M788 target practice.

The M789 HEDP is the combat round. It has a heat-treated steel body loaded with 27 grams of PBXN-5 explosive and a fluted copper shaped-charge liner. This advanced design ensures superior performance against threat armored vehicles.

ATK designed and developed the M759 point-detonating fuze used on the HEDP round. The M759 offers advanced performance features such as dual safety, longer arming delay, shallow graze function and greater long-range impact functioning.

The M788 TP is a low-cost, ballistically matched, inert training round. It is produced from the same quality materials and with the same exacting processes as the combat round.
