Key Points and Summary – While Ukraine fields a mix of Western and Soviet-era tanks, its own homegrown T-84 Oplot is rarely seen on the battlefield.
-The T-84 is a major upgrade over its Soviet predecessors, boasting superior speed, advanced optics that outrange Russian tanks, and a key design feature—a bustle autoloader—that prevents the catastrophic “Jack-in-the-Box” explosions common in Russian models.
-Despite these clear advantages, Ukraine was only able to procure about six T-84s for its own army due to chronic economic problems and the disruption of its supply chain after Russia’s 2014 annexation of Crimea.
Ukraine’s T-84 Tank: Why So Few and What Can They Do On the Battlefield?
Main battle tanks are a big component of Russian President Vladimir Putin’s continuing war against Ukraine. Much has been said about Russia’s use of its homegrown T-90, T-72, T-62, and T-54/T-55 MBTs (as well as the non-usage of its much-hyped T-14 Armata). On the other side, Ukraine has used American-made M1 Abrams and German-made Leopard tanks, in addition to leftover Soviet-era T-72s and T-64s.
However, what tends to get lost in the shuffle is Ukraine’s own homegrown MBT: the T-84 Oplot (“Stronghold”).
Why do we hear so little about the T-84, and what can it offer?
T-84 INITIAL HISTORY AND CONCEPT
Designed by the Kharkiv Morozov Machine Building Design Bureau (KMDB) and manufactured by the Malyshev Plant, the T-84 began production in 1994 – three years after Ukraine gained independence from the Soviet Union. It thus marked a major milestone for the newly independent Ukrainian arms industry – the first significant break from Russian military hardware in Ukraine. However, it didn’t enter into official operational service with the Armed Forces of Ukraine until 1999.
The T-84 was based on the Soviet-era 1987-vintage T-80UD MBT. It improved on its Soviet predecessor with a more powerful and more fuel-efficient 1,200 hp 6TD-2 two-stroke diesel engine, and a 26 power-to-weight ratio.
The T-84-120 variant also switched from the Soviet standard 125-mm main gun to a NATO-compliant 120-mm smoothbore cannon. It ditched the old-school carousel-type autoloader located under the turret in favor of a bustle autoloader. This improved the tank’s survivability, as Peter Suciu elaborates in an article for The Armory Life:
“It made the tank far less vulnerable to the so-called ‘Jack-in-the-Box’ effect whereby a direct hit at the turret can set off an explosion of the ammunition storage – causing the turret to be blown clean off the hull. Most of the ammunition was relocated to the turret bustle and separated from the crew by a bulkhead that protected the ordnance in the event of such a direct hit. The bustle compartment was similar to that of the U.S. Army’s M1 Abrams MBTs, while the T-84 also was equipped with NATO-style blowout panels that can release pressure in the event of internal explosion.”

-Maximum Speed: 70 km/h (43 mph) on paved roads, 45 km/h (28 mph) off-road
-Secondary Armament: 1 x 7.62 mm coaxial machine gun and 1 x 12.7 mm anti-aircraft machine gun
In a 2023 field interview with Ukraine’s UNITED24 media agency, some of the Oplot’s crew members praised their beloved homegrown tank.
As tank driver Leshy (surname not provided) told the interviewer, “Compared to other Soviet equipment, this one feels like you’re in a sports car. It’s much faster and there are four reverse gears. It can go 35 kilometers per hour backwards in the fourth gear all while the turret faces forward.”
Meanwhile, gunner Andrii Koval added that, “Our tank’s rangefinder and thermal imager gives us a considerable advantage on the battlefield. When we fight against Russian combat vehicles, we straight away know that their thermal imager and rangefinders are way worse. With ours, we can see 4,200 to 4,500 meters ahead, but they can only see up to 4,000 meters. Those 200 to 300 meters are to our advantage because we can see them, but they don’t even know we’re there.”
PRODUCTION PROBLEMS
Alas, the Oplot has been beset by poor production numbers. The Ukrainian government sold 49 of these MBTs to Thailand, and an additional four to the United States (the latter for testing & evaluation purposes).
Yet Kyiv could only afford to buy six of the advanced tanks for its own military due to the poor state of the Ukrainian economy in general, and the financially depleted tank-production facilities in particular.
Moreover, as noted by Chris Cappy of Task & Purpose, “According to this 2014 Ukrainian defense review publication, the annexation of Crimea in 2014 actually really hurt the production of the T-84 Oplot, because many of the key parts were manufactured there, forcing the Ministry of Defense to create a whole new supply chain.”
COMBAT PERFORMANCE
Not surprisingly, considering those low availability numbers – barely enough for a single tank platoon – the T-84 has been used sparingly in Ukraine’s fight against Russian aggression. The Ukrainian Army’s 14th Separate Mechanized Brigade is believed to be the operator of the Oplots, one of which was reportedly damaged by a Russian-made ZALA Lancet “kamikaze” drone in February 2023.
