The T-80 Is Russia’s Most Overrated Tank

This '80s design cost way too much and had a serious design flaw.

The T-80 is a glaring lesson in why heavily-armored tanks can hide major weaknesses. Once considered a premium tank by the Russian military establishment, T-80s suffered savage losses to lightly armed guerrillas during the First Chechen War. The tank’s reputation never recovered.

It wasn’t supposed to be this way. The T-80 was the last main battle tank to come out of the Soviet Union. It was the first Soviet tank to mount a gas turbine engine, giving it a top road speed of 70 kilometers per hour and an efficient power-to-weight ratio of 25.8 horsepower per ton.

This made the standard T-80B one of the most nimble tanks to come out of the 1980s.

The Chechen rebels’ combat prowess–and poor Russian tactics–was more responsible for the T-80’s losses than the inherent design. Though, it did have one major flaw. But in the end, it was too expensive and guzzled too much fuel. The Russian military grew to favor the more economical T-72 series instead.

The T-80 was an evolution over its predecessor, the T-64. As the most modern tank design of the late 1960s and early 1970s, the T-64 was a departure from the Soviet penchant for simple armored vehicle designs, such as the T-54/55 and T-62.

For instance, the T-64 was the first Soviet tank to replace human loaders with mechanical autoloaders, reducing the crew from four to three. The T-64’s second trend-setting innovation was the introduction of composite armor, which layered ceramics and steel together to provide superior resistance compared to only steel.

Further, the T-64 had lightweight, small diameter all-steel road wheels in contrast to the large, rubber rimmed ones on the T-55 and T-62.

The first mass produced variant, the T-64A, mounted the huge 125-millimeter 2A46 Rapira main gun, which was so popular that it came included on all subsequent Russian tanks … up to the T-90. Remarkably, the T-64A packed all of this potential into a petite 37-ton package–relatively light for a tank of this size.

But as marvelous as these innovations were, the T-64 had a sensitive 5TDF engine and unusual suspension–both prone to breaking down. As a result, the Soviet army deliberately assigned the tanks to units stationed close to its manufacturing plant in Kharkov.

Even worse, rumors circulated that the T-64’s new autoloader chomped off the arms of crew members who strayed too close. It’s a plausible scenario given the T-64’s tiny internal space.

While fixing the T-64A’s automotive maladies, the Soviets developed an interest in developing a new tank with a gas turbine engine. Gas turbines have high acceleration and an efficient power-to-weight ratio, can start quickly in cold weather without prior warm-up–a necessity in Russia’s frigid winters–and they’re lightweight.

On the downside, gas turbines guzzle fuel and have higher susceptibility to dirt and dust owing to their voracious air intake compared to conventional diesels.

The original base model T-80 didn’t enter active service until 1976–much later than planned. The Soviet tank industry had its hands full working out the T-64A’s kinks and gearing up for producing the T-72 as a cheaper backup option. At the same time, the Soviets were building more T-55s and T-62s for Arab allies which had lost hundreds of tanks during the 1973 Yom Kippur War.

The early-model T-80s also had their problems. In November 1975, the USSR’s then defense minister Andrei Grechko blocked the tank’s production because of its wasteful fuel consumption and few firepower advancements over the T-64A. Five more months passed before Grechko’s successor, Dmitriy Ustinov, authorized the new tank to go into production.

The original T-80’s production line continued for two years–not long–as it was already outclassed by the T-64B tank, which featured a new fire control system that could fire 9M112 Kobra missiles from its main gun. More serious, the T-80 was nearly three-and-a-half times more expensive than the T-64A.

The T-80B succeeded the baseline model in 1978. As the most advanced “premium tank” in the East, the Soviets beginning in 1981 assigned most T-80Bs to its highest risk garrison–the Group of Soviet Forces in Germany.

Its high speed earned it the nickname “Tank of the English Channel.” In Soviet war game calculations, T-80Bs were able to reach the Atlantic coast within five days–assuming that they didn’t run out of fuel.

This new variant borrowed from the T-64. In addition to firing conventional sabot, shaped charge and anti-personnel fragmentation shells, the T-80B’s 125-millimeter 2A46M-1 smoothbore gun could launch the same 9K112 Kobra missiles.

Since this anti-tank guided missile was considerably more expensive than regular tank shells, the tank only carried four missiles compared to 38 shells. The missiles were intended to swat down attack helicopters or ATGM-capable vehicles beyond the range of the T-80B’s conventional gun rounds.
