Nearly Half of Russia's Best Air Defense Weapon Has Been Destroyed By Ukraine

Russia's Pantsir is its best - and last

line of defense against incoming Ukrainian missiles and drones. Knowing that, Ukraine has now destroyed almost half of the Kremlin's inventory - or more than they could muster before the invasion.

The result of this systematic degradation is that even more important targets are now easier to hit, including troop concentrations, command headquarters, air fields and oil refineries. And this is a significant part of the reason why Russian casualties are rising even as it loses more previously occupied territory. JL

The Ground Truth Observatory reports:

Ukraine's forces has now destroyed 48% of Russia’s operational Pantsir-S1 fleet — the system “the most effective against our long-range drones.” The Pantsir-S1 is a self-propelled fortress on an eight-wheeled truck: twelve guided missiles stacked above two pairs of 30-millimeter autocannons, radars and electro-optical sensors that can track targets in darkness and bad weather, a crew of three, and an engagement envelope that stretches from 200 meters out to 20 kilometers. It sells for between $13 million and almost $15 million. The Pantsir is the last line of defense against a cruise missile, a drone or a bomb and what it is protecting: S-400 batteries, military airbases, the Kerch Bridge, oil refineries, the Kremlin itself. When a Pantsir dies, something much more valuable loses its bodyguard. Net losses are over 125 systems, more than the Kremlin's pre-war inventory. 

Somewhere in occupied Crimea a city-bus-sized truck died on camera. That was some fifteen million dollars. The drone that killed it was less expensive than a used car. Do that scene dozens of times over two years and you come to a confession Russia never wanted to hear said out loud: the most-used air-defense system in its arsenal has been halved.

The man who said it was no propagandist boasting to a camera that he could not live up to. In late 2025, Vasyl Malyuk, head of Ukraine’s Security Service, said his forces destroyed 48 percent of Russia’s operational Pantsir-S1 fleet since the start of that year — a system that he said is “the most effective against our long-range drones.” He wasn’t kidding. He was eulogizing it, one unit destroyed at a time.

This isn’t some old-fashioned relic. Know what the Pantsir-S1 really is. It entered Russian service in 2012, after a development history dating back to 1990, and is a self-propelled fortress on an eight-wheeled truck: twelve guided missiles stacked above two pairs of 30-millimeter autocannons, radars and electro-optical sensors that can track targets in darkness and bad weather, a crew of three, and an engagement envelope that stretches from 200 meters out to 20 kilometers. It sells on the export market for between $13 million and almost $15 million. More than a dozen countries bought it, from Algeria to Serbia to, reportedly, Saudi Arabia.

Its job is the loneliest and most important in the whole air-defence system. S-300s and S-400s get all the headlines, but they’re blind up close. The Pantsir is the last line of defense against a cruise missile, a drone or a bomb and what it is protecting: S-400 batteries, military airbases, the Kerch Bridge, oil refineries, the Kremlin itself. Russia even puts the newest version, the Pantsir-S1M, on 35-meter towers surrounding Moscow. When a Pantsir dies, something much more valuable loses its bodyguard.

So, how solid is the “half gone” claim? This is the forensic accounting, layer by layer. The 48 percent figure is an operational security claim by Ukraine’s SBU and cannot be independently verified in full. What can be proved is photographic evidence. Oryx, the Dutch open-source monitor that only counts losses it can see with its own eyes — a standard that dramatically undercounts, because not every kill gets filmed — has confirmed at least 35 Pantsir-S1 systems destroyed outright, with analysts tracking roughly 45 confirmed damaged or destroyed since 2022, a curve that has been steepening sharply in recent months.

Now do the math in reverse. Military analyst Oleksandr Kovalenko says Russia had 116 Pantsir systems in active combat service before the full-scale invasion, and that wartime production was limited to one or two a month — or 12 to 24 a year. Russian industry produces around 30, says Malyuk. Even at the generous figure, Russia can’t produce its way back to even. Net losses are over 125 systems when multiplying Oryx’s camera-verified kills by the standard open source multiplier of two to two-and-a-half to account for unphotographed kills, more than the entire pre-war combat inventory. The claim of “nearly half, gone” is not an exception. If anything, it’s conservative.

The kill footage speaks for itself. In October 2025, a Ukrainian RAM-2X loitering munition flew over 100 kilometers from the front line to strike a Pantsir parked at Luhansk airport — deep inside territory Russia has held for a decade. A few days later, the SBU’s Center A special unit hit launchers and radars across Crimea with drones. In February 2026, Ukraine’s Unmanned Systems Forces destroyed a variant of the Pantsir near Mariupol that analysts had never seen deployed in the field before — a configuration that had existed only as an exhibition mock-up since 2009. The last confirmed time it saw battle was its first. Russian crews have resorted to hiding under camouflage nets, moving about at night and even taking rare S1M systems off duty on Kerch Bridge to fill gaps. The drones just wait longer.

There is a harsh economic lesson embedded in this campaign. A Pantsir spends hundreds of thousands of dollars in missiles to shoot down drones that cost a few hundred, and every engagement uses radar hours, fuel and launcher life — whereas the defender has to be lucky every single time, and the attacker only once. Worse, they are running low on ammo themselves. In late 2025, video showed Russian crews loading outdated naval missiles onto ground-based Osa launchers and driving around Buk launchers with only one or two rounds each. By December, analysts at RUSI estimated that Russia was consuming more air-defence interceptors than it was producing. By spring Russian military bloggers were reporting acute shortages in Pantsir missiles specifically, with worrying signals about S-300 and S-400 stockpiles too. Ukraine has turned thousands of interceptor-equivalents into surface-to-surface missiles on the Russian side of the ledger — a defense ministry raiding its own shield to feed its sword.

The rot didn’t start in Ukraine, and honest analysts had been warning about it for years. In 2020, Turkish-backed forces destroyed or captured several Pantsirs near Al-Watiya air base in Libya, with a spokesman saying seven had been killed in days. Also that winter, Turkish strikes hit two more in Syria. In 2018, Israeli forces destroyed a Syrian Pantsir, supposedly because its crew left a mobile phone inside which became a beacon in a battlefield. One of their own was stuck in the mud of Kherson in March 2022 and was obliterated in the first week of its invasion. Every war since 2019 had demonstrated the same vulnerability to cheap unmanned aircraft. Ukraine is merely the first military to industrialize the lesson.

The consequences are no longer abstract. Ukraine’s General Staff said 24 Russian radar systems were damaged in Crimea alone between March and May, and the following winter the monthly toll of destroyed air-defense elements climbed from 21 in January to 25 in February and 36 in March, alongside dozens of portable radars swept away. The outer sensors were blinded, the skies over Russia thinned — and then the inevitable happened: in June Ukraine launched the biggest long-range drone attack on Moscow of the entire war, some 180 drones barreling toward the capital, strike footage showing the Kapotnya oil refinery burning — again — just fifteen kilometers from the city line. A nation that constructed the world’s densest air defense umbrella over its capital city now watches its refineries beneath it go up in flames.

Step back and the meaning of this campaign is clear. For three decades, countries purchased layered missile defense on the assumption that shields could defeat swords. The halving of the Pantsir is the loudest evidence yet that the promise has inverted. Attack technologies — cheap drones, long-range loitering munitions, mass-produced cruise missiles — now outstrip the ability to field or stockpile any interceptor. The United States had it in the Red sea. Israel and Gulf states saw it as a response to Iranian barrages. Europe’s war planners are watching the same telemetry with alarm, because every lesson Ukraine is learning at Russia’s expense is a lesson about tomorrow’s war everyplace.

Russia will keep turning out new Pantsirs at the rate of one or two a month, and will keep losing them faster than it can replace them, night after night, to cameras it cannot jam and arithmetic it cannot dodge. Half the shield is gone already. The other half is hungry for fuel, poor in missiles and hunting. Every refinery fire in Russia is the receipt for the fact that the fortress, stripped of its last line, is no fortress anymore.
