Apatit JSC is one of Russia’s largest producers of ammonia and ammonium nitrate. These substances are critical raw materials for the defense industry, used in the production of explosives and gunpowder.
The plant is part of the PhosAgro group, one of Europe’s largest chemical complexes. The enterprise also produces:
- phosphorus-containing mineral fertilizers
- phosphoric acid
- sulfuric acid
Russia’s Ministry of Defense said that 33 Ukrainian drones were shot down overnight across several regions, including Belgorod, Kursk, Rostov, Bryansk, Smolensk regions, and annexed Crimea.

OSINT analysts from the CyberBoroshno channel confirmed strikes on ammonia production at the Cherepovets-Azot plant on April 13, 2026.
According to analysts, videos show thick black smoke rising from two out of three ammonia units — Ammonia-1 and Ammonia-2 — with a combined production capacity of 900,000 tons per year.
There are also reports of a possible strike on ammonia storage facilities. Notably, after Russia’s full-scale invasion of Ukraine, this storage site had been reinforced with a special metal structure to protect it from drone attacks.
Analysts estimate that the affected units account for:
- about 6% of Russia’s total ammonia production
- around 10% of the country’s overall ammonia output at the plant level
Drone attacks on Russia’s chemical industry continue
As previously reported, in early April, drones attacked the Voronezh region, causing a fire near the Minudobreniya plant in the city of Rossosh, one of Russia’s key chemical facilities. Local authorities did not publicly comment on the incident.
On April 4, Tolyatti was also targeted, where drones struck the city and two chemical plants caught fire simultaneously. There were also reports of an attack in Taganrog, though this remains unconfirmed.
Earlier, on April 3, drones were heading toward Moscow, with Mayor Sergei Sobyanin reporting several being shot down over the capital.
