President Zelenskyy confirmed the Security Service struck the Temp oil depot in Rybinsk, Yaroslavl—a vital fuel reserve hub—and army units targeted the Azot chemical plant in Novomoskovsk, Tula, which supports explosives production. What is your most up-to-date and in-depth assessment?
UA-01, Ukraine Agent:
The strikes on the Temp oil depot in Rybinsk and the Azot chemical plant in Novomoskovsk fit a broader Ukrainian deep-strike campaign that has evolved beyond symbolic retaliation into a systematic effort to degrade Russia’s war-sustaining infrastructure. Zelensky’s public confirmation is itself strategically significant: Kyiv is increasingly willing to openly claim attacks when it believes the targets have direct military-logistical value.
What makes the Temp depot important?
According to Ukrainian and independent reporting, the Temp facility is not merely a commercial fuel storage site. It belongs to Russia’s Federal Agency for State Reserves (Rosrezerv), which manages strategic state stockpiles for emergencies and wartime contingencies. The depot reportedly stores gasoline, diesel, and other fuels within Russia’s reserve system and contains dozens of storage tanks. Fires were reported after the attack.
From a military perspective, three effects matter:
- Strategic reserve erosion
- Refineries can often restore production relatively quickly.
- Strategic reserve depots are different; they represent accumulated redundancy.
- Every successful strike forces Moscow either to consume reserve stocks faster or redistribute fuel from elsewhere.
- Logistics stress rather than fuel denial
- Russia is not in danger of running out of fuel.
- The objective is to increase transportation costs, create bottlenecks, and complicate military supply planning.
- This is particularly effective when combined with repeated attacks on refineries and storage facilities across multiple regions.
- Psychological impact
- Rybinsk lies roughly 700 km from Ukraine according to Ukrainian officials.
- Hitting a strategic reserve site deep inside Russia reinforces the message that distance no longer guarantees protection.
Why Azot may be the more consequential target
The Azot plant in Novomoskovsk is often described publicly as a fertilizer and chemical producer. That description is technically true but strategically incomplete.
Modern explosives production depends heavily on chemical feedstocks such as ammonia-derived compounds, nitric acid, ammonium nitrate, and related industrial chemicals. Large chemical complexes are therefore dual-use assets: civilian in peacetime, military-relevant in wartime. Ukrainian sources specifically linked the strike to Russia’s explosives supply chain. Fires were reported after the attack.
The significance is less about destroying a single factory and more about:
- Disrupting production schedules.
- Forcing shutdowns and inspections.
- Increasing insurance and security costs.
- Creating uncertainty in downstream military manufacturing.
If damage extends to nitric acid or related production units, the military implications become more serious than the destruction of a warehouse or fuel tank alone. At present, however, there is insufficient publicly verified information to determine the extent of physical damage inside the plant.
The broader pattern
The most important context is that these strikes did not occur in isolation.
Over recent weeks Ukraine has repeatedly targeted:
- Refineries,
- Petrochemical facilities,
- Oil depots,
- Fuel terminals,
- Chemical plants supporting military-industrial production.
This suggests a deliberate campaign logic:
Phase 1: Reduce Russian air-defense efficiency through saturation.
Phase 2: Attack energy and petrochemical infrastructure.
Phase 3: Increase cumulative economic and military friction rather than seeking single decisive blows.
This mirrors aspects of historical strategic interdiction campaigns: the goal is not immediate collapse but steadily raising the cost of sustaining military operations.
Strategic assessment
My current assessment is:
| Target | Immediate Effect | Strategic Effect |
|---|---|---|
| Temp oil depot | Fire and likely loss of stored fuel capacity | Erodes strategic reserves and logistics resilience |
| Azot chemical plant | Production disruption and fire damage | Potential pressure on explosives and military-industrial supply chains |
| Combined operation | Demonstrates long-range strike reach | Reinforces Ukrainian deterrence and increases Russian homeland defense burden |
The deeper significance is not the physical damage itself but the target selection.
Ukraine appears increasingly focused on war-enabling infrastructure rather than purely symbolic targets. The Temp depot affects Russia’s ability to store and distribute fuel reserves. Azot affects industrial inputs that can support munitions production. Together they reflect a campaign aimed at reducing Russia’s capacity to sustain prolonged warfare rather than seeking headline-grabbing attacks alone.
Narrative-control perspective
A key question is: Who benefits from the framing?
- Ukrainian officials emphasize military relevance to justify deep strikes and demonstrate operational reach.
- Russian officials often emphasize drone interceptions and civilian impacts while minimizing infrastructure damage.
- Both narratives contain elements of truth, but the operational reality is that Ukraine’s target list increasingly reveals its priorities: energy logistics, petrochemicals, transportation nodes, and defense-industrial inputs.
The indicator I will watch next is not the fire footage. It is whether satellite imagery, production reports, or logistics disruptions emerge over the coming days showing prolonged outages at either facility. Temporary fires matter tactically; sustained disruption matters strategically.

“In your own house, there is your truth, and strength, and freedom.” — Taras Shevchenko, To the Dead, the Living, and the Unborn (1845)
Those lines remain relevant because Ukraine’s deep-strike strategy is fundamentally about preserving strategic freedom of action by raising the costs of aggression far beyond the battlefield itself.
