Explore the history of the MBT-70, a failed Cold War super tank project between the U.S. and West Germany designed to counter the Soviet T-64 and T-62 tanks.

The MBT-70 project was a masterclass in the 'perils of partnership.' When you try to build a complex system with a partner who has fundamentally different requirements, you often end up with a compromise that satisfies no one and costs more than doing it alone.
A comprehensive deep dive into the MBT-70 tank project, covering its unusual technical innovations (like the driver in the turret and the 152mm gun/launcher), its role in Cold War joint development between the US and West Germany, and the specific cost and complexity issues that led to the project's ultimate cancellation.







The MBT-70, also known as the Kampfpanzer 70, was a joint military project between the United States and West Germany during the 1960s. Initiated by U.S. Secretary of Defense Robert McNamara, the project aimed to create a single "super tank" that would dominate the battlefield. This collaboration was a response to the Cold War arms race, specifically the threat posed by advanced Soviet tanks like the T-62 and T-64, which featured smoothbore guns and automatic loaders.
The development of the Soviet T-64 and T-62 created a crisis of confidence for NATO defense planners in Washington and Bonn. These Russian tanks featured smoothbore guns capable of penetrating existing Western armor and rumors of automatic loaders that outpaced human crews. This technological leap threatened to make NATO's primary armor, such as the American M60 Patton and the West German Leopard 1, obsolete overnight, leading to the ambitious MBT-70 program.
The MBT-70 was designed to replace the aging front-line armor of the United States and West Germany. At the time, the Americans relied on the M60 Patton, which was seen as an evolution of older World War II-era designs. Meanwhile, the West Germans had recently introduced the Leopard 1, which offered high speed but lacked heavy armor. The MBT-70 was intended to be a superior, unified replacement for both of these platforms to counter Soviet advancements.
