On October 31, Ukraine’s Main Intelligence Directorate struck the strategic 400-kilometer Koltsevoy pipeline near Moscow, reportedly destroying all three lines that supplied fuel to Russian military forces.
The attack marked one of Kyiv’s most daring and impactful covert operations inside Russian territory since the start of the full-scale invasion.
Ukrainian officials described the covert operation as targeting a vital artery for gasoline, diesel, and jet fuel, which connects refineries in Ryazan, Nizhny Novgorod, and Moscow.
The action not only brought a significant logistical setback to Russian military operations around the capital but also reinforced Ukraine’s persistent focus on energy infrastructure as a tool of war.
How was Russia’s critical Koltsevoy pipeline destroyed?
According to Ukrainian military intelligence, specialized units executed the strike in the Ramensky district, a heavily secured area of Moscow Oblast. Despite anti-drone defenses and armed guards, the operation succeeded in disabling all three branches of the pipeline simultaneously.
Initial reports suggest the use of drones or saboteur teams capable of bypassing extensive security systems to reach critical segments of the infrastructure.
The Koltsevoy line was essential for transporting fuel directly to Russian military garrisons near Moscow, with an annual handling capacity cited as up to 3 million tons of jet fuel, 2.8 million tons of diesel, and 1.6 million tons of gasoline.
The loss of the pipeline is expected to complicate resupply efforts and force Moscow to seek alternative, less efficient routes for its military fuel needs.
Did you know?
The pipeline is a crucial logistical asset for Russia's armed forces, used to supply fuel to military units, particularly those stationed near Moscow.
What is the significance of targeting Moscow’s fuel supply?
Destroying a supply line of such capacity holds immediate military significance and broader political resonance. The Koltsevoy pipeline was a secure and largely unmonitored link between Russian refineries and front-line stores, ensuring steady flows of fuel for military vehicles and aircraft.
Its disruption leaves Russian forces more vulnerable to shortages and raises operational costs for the Kremlin. More symbolically, the attack demonstrates Ukraine’s ability to conduct deep, high-impact strikes within Russia.
HUR chief Kyrylo Budanov stated these operations have “more impact than sanctions,” hoping to inflict direct costs and sap Moscow’s offensive potential.
The announcement reinforced Ukraine’s growing expertise in targeting infrastructure with significant downstream consequences for the Russian war machine.
How has Russia responded to intensified Ukrainian attacks?
As Ukrainian strikes have intensified on Russian energy infrastructure, Moscow has escalated its retaliation. October saw Russia fire a record 270 missiles at Ukrainian targets and launch 223 drones overnight into November, resulting in mass casualties and extensive blackouts across Ukraine.
In the wake of the Koltsevoy pipeline destruction, Russian state and defense officials promised reinforcement of critical sites around the capital and vowed yet more aggressive air and drone campaigns against Ukrainian energy and civilian infrastructure.
The cycle of strikes and counterstrikes marks a stark escalation in the energy war, with both sides viewing infrastructure sabotage as key to breaking the other’s will and capacity to fight.
Ukrainian sources argue that Western sanctions alone have been insufficient, pushing Kyiv to escalate precision attacks deep within Russian territory.

Are these strikes shifting the conflict’s balance?
While it is too soon to measure the long-term effect, the disruption of Koltsevoy represents a tangible blow to Russian military logistics. Ukraine has systematically targeted refineries, storage depots, and transport arteries throughout 2025, aiming to degrade Moscow’s offensive stamina without waiting for a broad international consensus.
Some Western analysts suggest that these attacks, if sustained, could eventually undermine Russia’s operational tempo.
However, Russia’s adaptive logistics, such as shifting supplies to rail or road and rerouting through less vulnerable pipelines, may limit the initial impact.
The specter of further attacks will force costly new investments in protection and redundancy, adding to the Kremlin’s economic strain.
What are the humanitarian and international ramifications?
The escalation of infrastructure warfare has amplified human suffering on both sides of the border. Drone and missile strikes have resulted in civilian deaths and rising displacement, particularly as October’s Russian barrages left swathes of Ukraine without electricity, heating, or water.
International observers condemned the growing reliance on strikes against civilian and energy targets, calling such tactics a dangerous trend with the potential to spill over into nuclear safety concerns.
The G7 and major allies expressed alarm at the “devastating social, environmental and economic consequences” for Ukraine, increasing calls for both sides to protect noncombatants.
Ukrainian officials, on their part, defend their infrastructure strikes as legitimate responses to Russian aggression, aiming to shorten the war and force a return to the negotiating table.
In the weeks ahead, monitoring Moscow’s logistical adaptations and Kyiv’s willingness to escalate further will be critical in judging the evolving shape of this high-stakes energy war.
The latest pipeline strike suggests both sides are ready to risk greater escalation to achieve strategic advantage.
