US to develop new M1E3 Abrams battle tank

The US Army has announced the development of a new main battle tank, the M1E3 Abrams, to replace the upgraded M1A2 SEPv4.

Here's What We Know

This decision was made due to the need to reduce the weight of the tank, increase its survivability and improve its operational capabilities. According to a recent report by the Congressional Research Service (CRS), this approach is part of the Army's strategic modernisation plan.

The M1 Abrams tank has been in use since the early 1980s and has undergone numerous upgrades, including the M1A2 SEPv3 and SEPv4, which have improved firepower, communications and protection. However, as Major General Glenn Dean has noted, further enhancements to the Abrams capability have been impossible without significantly increasing its weight.

The war in Ukraine has highlighted the importance of modular designs and integrated defence systems that allow vehicles to be quickly adapted to new threats.

The new M1E3 Abrams tank will be based on the Modular Open Systems Architecture (MOSA), which will simplify its modernisation. Although official specifications have not yet been released, according to CRS, it may feature a hybrid-electric drive, automatic loading system, new gun, advanced ammunition, integrated drone defence, improved communications and command systems, and artificial intelligence to improve combat effectiveness.

The M1E3 Abrams will be developed by General Dynamics Land Systems (GDLS), which was awarded a contract by the US Army in May 2024. Over the next 18 months, the technology will be improved, and the tank will be developed in conjunction with the XM30 infantry fighting vehicle. Initial operational capability of the M1E3 is expected by 2030.

While this process is underway, production of the M1A2 SEPv3 will continue, but at a reduced rate.
