Orbital ATK awarded contract for M830A1 HEAT MP-T cartridge

Alliant Techsystems Operations LLC, a wholly owned subsidiary of Orbital ATK, Inc., has been awarded a contract for M830A1 high explosive anti-tank multi-purpose with tracer (M830A1 HEAT MP-T) cartridge recapitalization.

The firm-fixed-price contract, valued around $7.5 million, was awarded by the U.S. Army Contracting Command.

The contract work will be performed in Plymouth, Minnesota, with an estimated completion date of Aug. 30, 2019.


The M830A1 is an American high explosive anti-tank (HEAT) round meant primarily for the 120 mm M256 main gun of the M1A1 and M1A2 Abrams main battle tanks (MBT).

It is the successor of  M830 round and provides greater lethality through a higher initial velocity and a multi-purpose fuse.

Like the M829 armour-piercing fin-stabilized discarding sabot (APFSDS) round, it features a discarding sabot around a sub-caliber warhead.

The cartridge weighs 49.2 lb (22.3 kg), with the projectile accounting for 25.1 lb (11.4 kg).

The rounds have multi-purpose warheads which are used to defeat armored vehicles, helicopters and soft targets such as bunkers. The M830A1 was first fielded in 1994.

The M830A1 is to be replaced by the Advanced Multi-Purpose (AMP) round currently in development. In January 2017, Orbital ATK was selected to complete development of the AMP.
