How Long Will It Take the U.S. Army to Replace the Abrams Tank?

The vaunted and upgraded main battle tank may actually be around for many decades to come.

The Army’s current early work on designing a new Optionally Manned Tank for the future may bring implications for the services’ long-term plans for the Abrams tank, all while also introducing the possibility that a new, lightweight, potentially unmanned high-tech armored vehicle could complement and fight alongside the Army’s Abrams tank for decades into the future.

While any prototypes or actual bending of metal is still likely years away, Army war planners and weapons developers have launched a full-scale exploration into possibilities for a future tank, including armor, weapons, tactics and anticipated future threat scenarios. At the moment, the work is largely conceptual and also being done through design renderings, digital engineering and computer simulations. The Army plans to decide upon a plan within the next several years.

What might progress with a new robotic Abrams replacement mean for the combat-tested Abrams? Will it live to fight decades into the future or possible face full replacement? The answer may be a bit of both, given the success of the Abrams and the ongoing extent to which it continues to be modernized. The Army is already moving out vigorously on a new v4 variant of the Abrams to emerge in coming years, a plan which will bring a much more lethal tank to the force with new multi-purpose ammunition, next-generation infrared sensors, armor composites, on board computing and manned-unmanned teaming technologies.

There is also considerable consensus that the Abrams has not only proven effective in warfare over a number of years, but is also an almost entirely new tank when compared with its 1980s birth. In short, it appears heavy armor may be here to stay, at least for a number of years to come. At some point, likely not too far off, it will be accompanied, and quite possibly ultimately replaced, by a new platform.

“We are very happy with where the M1 tank is today. Part of our job is to look into the future and determine if there is an emerging requirement. We may just keep the Abrams forever. We are looking at the capabilities of our adversaries and technologies based on advancements from our industry partners. Right now we need to lay out all the desired capabilities and lay out options for our senior leaders and communicate with our industry and Congressional partners,” Coffman added.

Heavy tracked vehicles, such as the Abrams, bring substantial off-road advantages as well certain limitations, presenting an interesting balance of variables informing current plans for future armored vehicles. As the Army seeks to maximize its expeditionary warfare capacity and emphasize rapid deployability, weapons developers are searching for that optimal blend of attributes best suited to bring the Army forward into future warfare.

“We have to fight in places that don’t have the infrastructure with roads and bridges and often in places with rolling terrain,” Coffman said.

All of these dynamics point to the central predicament, challenge or paradoxical balance unique to designing an armored vehicle for future war. Weight and speed, attributes which may seem at odds with one another, must be reconciled or balanced in an optimal way.

“We have to transit the local roads and infrastructure, but you can’t sacrifice speed and mobility for weight. There is a sweet spot that every Army on earth looks for. Let’s not make this so heavy that it loses mobility. Let’s not make it so lethal that now you sacrifice mobility,” Coffman said.
