Desperate to make good the loss of around 2,000 tanks in the first year of its wider war on Ukraine, Russia has begun pulling out of long-term storage 70-year-old T-54 and T-55 tanks.
The tanks are hopelessly obsolete. “Expendable,” according to one Russian expert. That should be most apparent at night, where the T-54/55 is at a massive disadvantage in a battle with Ukraine’s more modern armored vehicles.
The problem comes down to optics. The crew of a Ukrainian T-64, T-72 or T-80 tank—to say nothing of a Challenger 2, Leopard 1 or 2 or M-1—can see at night without betraying its position.
The crew of an early-model T-54/55 can’t.
When the T-54/55 was a new design, in the late 1950s, the standard night-fighting technology was a combination of infrared-sensitive optics and an infrared spotlight.
While an improvement over a white spotlight, which would be visible to anyone on the battlefield and thus immediately give away a tank’s position, an infrared spotlight still is visible to well-equipped enemy forces. “Night-vision devices can be used to detect the enemy’s use of infrared light,” the U.S. Army explained in the 1978 edition of its Field Manual 31-36.
The T-54/55 crew could switch off its searchlight and disappear into the darkness, but then it would struggle to spot targets. A T-54/55 can hide at night, but only if it doesn’t fight.
No Ukrainian tank suffers the same limitation. Every tank and most of the fighting vehicles in front-line use with Ukrainian forces have passive night-vision. Infrared or image-intensification sights that can see in the dark without the help of a spotlight.
Now to be clear, later T-54/55s—those the Soviet army upgraded in the 1970s and ’80s—might have the TKN-1SM or some other passive night sight.
But it’s apparent, from videos that have circulated online, that many of the T-54/55s the Russians recently have pulled out of storage lack passive night vision. Their L-2G infrared spotlights plainly are visible atop their turrets.
Don’t expect the Russians to upgrade those old tanks with modern sights. After all, the whole reason the Kremlin is reactivating T-54/55s is that Russian industry currently lacks the components—optics and ball bearings, in particular—to build new T-90Ms and T-72B3s or even restore older T-72s and T-80s.
“The T-55 in this sense is a resource-saver and an opportunity to buy time,” a Kremlin source told Volya Media.
So the old tanks likely will roll into battle with the same guns, fire-controls and armor they had 70 years ago. And the same night-fighting systems, too: spotlights that give away their positions.
