Ukraine’s Strike Campaigns Will Likely Continue to Hurt Russia’s Economy and Military Operations in Ukraine

Institute for the Study of War | Kateryna Shymkiv

Ukrainian forces intensified long- and intermediate-range strike campaigns between January and June 2026, striking 22 Russian oil refineries up to 2,000 kilometers from the border and causing widespread gasoline shortages across 78 Russian federal subjects. These systematic attacks targeting refineries, oil depots, and transshipment hubs have severely reduced domestic petrochemical production while disrupting military supply lines along critical ground lines of communication such as the M-14 highway.

Russian diesel output fell by one million metric tons in April 2026 and 600,000 metric tons in May 2026, directly compromising frontline ammunition and vehicle deliveries toward Lyman and Hulyaipole. Kremlin price caps cannot fix basic production deficits. To mitigate domestic panic, Moscow instituted fuel export bans and emergency imports from Belarus, Kazakhstan, and India, alongside drawing down strategic fuel reserves. However, severe air defense shortages prevent the Russian military from simultaneously protecting vast rear energy infrastructure and active frontline sectors against expanding Ukrainian drone swarms.

Comment

The attrition of military fuel transport along the M-14 highway demonstrates how deep logistics sustainment degrades long before frontline combat units deplete their organic operational reserves. Disruption to bulk fuel distribution forces mechanized units to rely on decentralized, tactical resupply vehicles that are highly vulnerable to localized drone interdiction. This bottleneck shifts sustainment from high-capacity pipeline and rail networks to fragmented road logistics, creating severe distribution friction across the southern theater.

Specifically, short-range point-defense assets like the Pantsir-S1 system are diverted to guard fixed refining infrastructure in the deep rear, pulling mobile air defenses away from intermediate transit corridors. Without layered air defense screens along secondary supply routes, vulnerable soft-skinned tankers operating between Rostov-on-Don and occupied Zaporizhia face continuous, unmitigated precision strikes.

Strategic Question for Discussion

If Russian command continues reallocating Pantsir-S1 batteries to shield deep rear refineries, which secondary GLOC route presents the highest systemic vulnerability to Ukrainian interdiction?

The available evidence points toward the M-14 highway corridor as the primary point of failure due to its heavy reliance on soft-skinned road tankers. Reallocating point-defense batteries away from intermediate transit nodes leaves bulk fuel convoys exposed to unmitigated drone strikes, rapidly cascading into localized fuel starvation for frontline mechanized formations.
