The United States has presented a prototype of its next-generation main battle tank, the M1E3 Abrams, featuring a fully uncrewed turret, hybrid propulsion, and a redesigned crew layout aimed at improving survivability and efficiency.

According to The War Zone on March 19, the US Army has shifted its modernization strategy away from further upgrades of the M1A2 Abrams platform in favor of developing the M1E3 as a new-generation system.
The project is being led by General Dynamics Land Systems (GDLS) under the oversight of the Army’s Ground Combat Systems program office based at the Detroit Arsenal.
What changed in the design
The M1E3 introduces a significant departure from previous Abrams variants through the use of a fully uncrewed turret. All three crew members—commander, gunner, and driver—are relocated into a heavily armored capsule within the hull, reducing exposure to threats typically directed at the turret.

According to Army Recognition, the tank is expected to retain a 120mm smoothbore gun derived from the M256 family, supported by an autoloader system. This configuration removes the need for a human loader and allows for more consistent firing rates while reducing turret volume.
The platform is also designed to integrate a remote weapon station equipped with a 40mm automatic grenade launcher, a 7.62mm machine gun, and a launcher for FGM-148 Javelin anti-tank missiles.
Power, weight, and efficiency
A key focus of the M1E3 program is reducing weight and improving fuel efficiency. According to The War Zone, the US Army aims to bring the tank’s weight down to approximately 60 tons, compared to around 78 tons for the latest M1A2 SEPv3 configuration.
The propulsion system will shift from the traditional gas turbine engine to a hybrid setup. Dr. Alex Miller, the Army’s chief technology officer, stated: “It will be hybrid. It will not be fully electric.”
He added: “We do not want a fully electric platform because there are no charging stations on the battlefield. You need liquid fuel to generate actual power.”
Miller also noted that early calculations suggest the hybrid system could be “about 40 percent more efficient” than current configurations.
Protection and digital systems
The M1E3 incorporates modular, multi-layered armor, with options to include depleted uranium protection. The hull features a V-shaped design to mitigate mine and improvised explosive device threats, while internal survivability is enhanced through fire suppression systems and blast-attenuating seating.
The tank is expected to support advanced active protection systems, including Trophy and the US Army’s Modular Active Protection System (MAPS), designed to counter anti-tank guided missiles and top-attack munitions.
Additionally, the platform integrates a radar-based system for 360-degree drone detection and tracking, enabling counter-UAS capabilities directly from the vehicle.
The integration of Javelin missiles raises practical concerns. The system requires manual reloading, which could force crew members to exit the vehicle or access external components—potentially undermining the safety advantages of an uncrewed turret design.
Earlier, according to reports on March 16, Ukraine has been testing an upgraded Leopard 1A5 tank equipped with the Belgian Cockerill 3105 unmanned turret, which introduces indirect fire capability and reduces the crew to three personnel.
The system is currently undergoing evaluation, with early results described as positive, and a Ukrainian unit operating the vehicle expected to move toward a combat zone.
