Known as one of the biggest and baddest tanks to enter the battlefield, the M1 Abrams is a staple of U.S. military might on the ground. Although it was introduced almost half a century ago, the M1 Abrams features advanced tech, formidable firepower, and superior armor that rivals even the newest main battle tanks.

Originally developed to replace the M60 Patton, the design of the M1 Abrams is focused on firepower. The main gun is a 120mm smoothbore Rheinmetall cannon, which can fire a variety of munitions including armor-piercing and high-explosive rounds. Since the 1980s, the Abrams has adopted an onboard fully digital Ballistic Computer System (BCS) which helps with advanced targeting. (This Russian tank has bigger guns than the M1 Abrams.)

The tank can reach speeds over 40 mph with an output of 1,500 horsepower as it’s powered by the Honeywell AGT1500 gas turbine engine which can operate on a variety of fuels. It has a fuel capacity of roughly 500 gallons, which is enough fuel to last for almost 300 miles without refueling.

The M1 Abrams is the biggest tank to date built for the United States weighing in at a whopping 139,000 pounds. It is one of many tanks that has played an integral part of the military history of the U.S. (These are the 30 most mass-produced tanks since WWII ended.)

24/7 Wall St. is taking a closer look at American-made tanks. To determine the biggest tanks in U.S. military history, 24/7 Wall St. reviewed a list of tanks used by the U.S. military from Military Factory, an online database of military vehicles, aircraft, arms and more used by militaries across the world. All U.S. tanks are ranked here according to their weight. Additional data on the type of tank, crew size, and more also came from Military Factory. We excluded tanks that were not mass-produced or had production runs less than 250 units.

Here is a look at the biggest U.S. tanks ever built:
