Heavily armed and armored, the modern tank is a versatile and mobile weapons platform, and a critical piece of contemporary warfare.

This visualization shows the top 15 global tank fleets, using data from the 2024 Military Balance report from the International Institute for Strategic Studies (IISS).

Let’s take an in-depth look at the top three fleets:

1. United States

As the world’s pre-eminent military power, it’s perhaps no surprise that the United States also has the largest tank fleet, by a wide margin.

In total, they have just over 45,000 armored fighting vehicles in operation, along with 2,640 main battle tanks (MBTs), and 12,800 vehicles in storage, of which 2,000 are main battle tanks.

The U.S. is internalizing the lessons from the ongoing invasion of Ukraine, where Western-supplied anti-tank weapons and massed Ukrainian artillery have been cutting Russian tanks to pieces. As a result, the U.S. recently canceled an upgrade of the M1 Abrams in favor of a more ambitious upgrade.

Meanwhile, the U.S. is nervously eyeing a more confident China and a potential clash over Taiwan, where air and naval forces will be critical. However, a recent war game showed that Taiwanese mechanized ground forces, kitted out with American-made tanks and armored fighting vehicles, were critical in keeping the island autonomous.

2. Russia

According to Oryx, a Dutch open-source intelligence defense website, at time of writing, Russia has lost almost 2,800 main battle tanks since invading Ukraine. Considering that in the 2022 edition of the Military Balance, Russia was estimated to have 2,927 MBTs in operation, those are some hefty losses.

Russia has been able to maintain about 2,000 MBTs in the field, in part, by increasing domestic production. Many defense plants have been taken over by state-owned Rostec and now operate around the clock. Russia is also now spending a full third of their budget on defense, equivalent to about 7.5% of GDP.

At the same time, they’ve also been drawing down their Soviet-era stockpiles, which are modernized before being sent to the front. Just how long they can keep this up is an open question; their stockpiles are large, but not limitless.

3. China

China holds the third overall spot and top place globally for the number of main battle tanks in operation. Untypically, the People’s Liberation Army has no armored vehicles in storage, which perhaps isn’t surprising when you consider that China has been rapidly modernizing its military and that stockpiles usually contain older models.

China also has one of the world’s largest fleets of armored fighting vehicles, second only to the United States. Breaking down that headline number, we can also see that they have the largest number of light tanks, wheeled guns, and infantry fighting vehicles.

This is equipment that would be integral if China were to make an attempt to reunify Taiwan with the mainland by force, where lightly armored mechanized units need to move with speed to occupy the island before Western allies can enter the fray. It’s worth noting that China also has one of the world’s largest fleets of amphibious assault vehicles.

End of the Tank?

Many commentators at the outset of Russia’s invasion of Ukraine, were quick to predict the end of the tank, however, to paraphrase Mark Twain, reports of the tank’s demise are greatly exaggerated.

With the U.S. and China both developing remote and autonomous armored vehicles, tanks could be quite different in the future, but there is nothing else that matches them for firepower, mobility, and survivability on the modern battlefield today.
