Northrop Grumman has introduced their newly-developed M1147 Advanced Multi Purpose (AMP) 120mm cartridge for the U.S. ABRAMS M1A2 main battle tank. This new line-of-sight type ammunition is the next generation high explosive multipurpose round intended to replace other types of projectiles currently used in ABRAMS M1A2.The XM1147 (M1147) Advanced Multi-Purpose (AMP) ammunition is a 120mm round intended as the replacement for four 120mm rounds within the US Army. The AMP is a lethal weapon with the ability to perform as Multi-Purpose Anti-Tank (MPAT), M830A1, M830, and High Explosive Anti-Tank (HEAT) round are now in service. The key of the new tank round is the ability to use three fusing modes with the airburst one allowing to target dismounted troops/personnel by detonating at a given height. The other two fusing modes are Point Detonation (impact) and Point Detonation-Delay which allows to penetrate the target such as bunkers and fortifications. The new round is expected to enter into service in the 2020s along with the M1A2 SEP v3/4 main battle tanks. In February 2017 Orbital ATK was selected to complete the development of the AMP by 2019-2020. The first XM1147 rounds were ready for fielding in January 2021.
