Overview

The M1A2 SEP v3 (now designated M1A2C) is the most advanced fielded version of the American Abrams, a tank whose design philosophy prizes crew protection and a powerful sensor-and-fire-control suite. It retains the 120mm M256 smoothbore gun and the gas-turbine engine that has defined the Abrams since the 1980s, but adds upgraded armour, better power generation, an ammunition data link for programmable rounds, and improved networking and diagnostics.

Built by General Dynamics Land Systems, the Abrams remains the backbone of US Army armour and serves with allies including Australia, Poland and several Gulf states. The SEP v3 is a bridge toward the leaner, lighter M1E3 concept, which is intended to address the platform's considerable weight and fuel demands.

A small number of Abrams were supplied to Ukraine in 2023 and saw combat in 2024, with several lost to drones, mines and anti-tank missiles. Those losses fed a wider debate about the survivability of heavy armour on a battlefield saturated with cheap loitering munitions, reinforcing the case for the Army's move toward a next-generation design.
