    The Challenge of Designing a Next-Generation Tank for Global Operations

    As the US Army acknowledges the need for tanks in combined-arms operations in Europe and Asia, it also recognizes that potential adversaries are developing weapons that can effectively counter the aging M1 Abrams tank. Now, the US Army faces the dilemma of designing a next-generation tank that can effectively operate in both European and Pacific theaters.

    The main issues impacting the current M1 Abrams tank are its outdated design and limitations for operating in different regions. The tank’s advantages in terms of mobility, firepower, and protection are at risk due to its aging Cold War design, as stated in a recent report by the Army Science Board. Moreover, the tank was primarily designed for European terrains and is ill-suited for the jungles and remote islands of the Pacific. The report emphasized that the Indo-Pacific’s logistical challenges and underdeveloped infrastructure further exacerbate this problem.

    While tanks have historically played a crucial role in Western-centric warfare, their significance in the Pacific has been secondary due to the nature of infantry battles fought on rough terrains or on beaches and surf zones. However, the US Army recognizes the value of tanks in the Pacific theater, particularly in restricted terrains. General Charles Flynn, commander of US Army Pacific, highlighted the necessity of tank capabilities in such terrains.

    With the need to prepare for potential conflicts in the Pacific, the Army Science Board suggests that fifth-generation combat vehicles, which are the successors to the Abrams and Bradley, must be lightweight enough for easy transportation by sea and air. The current fleet of armored vehicles, designed to counter Soviet tanks in Europe, falls short in terms of deployment and sustainment in the Pacific theater.

    It is evident that the Abrams tank era is coming to an end. The tank is susceptible to threats like drones and top-attack anti-tank missiles. Retrofitting the tank with new technologies would be inadequate, as it cannot effectively counter advancements in anti-tank guided missiles. Therefore, the US Army is actively seeking a next-generation tank that is lighter, better protected against advanced threats, and manned rather than autonomous.

    Finding the ideal solution presents challenges. The Army Science Board explored various alternatives, such as a 60-ton tank with a 130-mm gun and a three-person crew or a 40-ton light tank with a heavy cannon. However, these options were deemed either insufficiently mobile or lacking adequate protection. One concept that intrigued the study was the idea of a “robotic wingman,” a 30-ton vehicle armed with a hypervelocity missile, to accompany manned tanks.

    The US Army has been searching for next-generation armor for over two decades, with ongoing projects like the XM30 and M10 Booker. As technology advances and threats evolve, the challenge lies in designing a tank that can effectively counter these new challenges while maintaining mobility, firepower, and protection across different theaters of operation.


    1. Why is the current M1 Abrams tank inadequate for future battlefields?

    The M1 Abrams tank has an outdated Cold War design, making it vulnerable to modern threats such as drones and advanced anti-tank missiles. Additionally, its weight and design were primarily intended for European terrains, limiting its effectiveness in the jungles and remote islands of the Pacific.

    2. How does the Pacific theater differ from Europe in terms of tank operations?

    The Pacific theater presents challenges such as restricted terrains, longer distances, and underdeveloped infrastructure. Tanks need to be lightweight for easy transportation by sea and air, which is not a characteristic of the current heavy M1 Abrams tank.

    3. What are the potential alternatives to the M1 Abrams tank?

    The Army Science Board has explored various alternatives, including a 60-ton tank with a three-person crew and a 130-mm gun or a 40-ton light tank with a heavy cannon. However, these options have limitations in terms of mobility or protection. Another concept that intrigued the study is the idea of a “robotic wingman” vehicle to accompany manned tanks.

    4. What factors are influencing the design of the next-generation tank?

    The design of the next-generation tank is influenced by the need to counter modern threats, lightweight mobility for global operations, and enhanced protection against advanced weapons. The tank must strike a balance between these factors while maintaining the key capabilities of mobility, firepower, and protection.
