Ukraine's Defense Forces struck a major oil refinery, a strategic bomber airbase, a military fuel depot, and multiple drone-related facilities across Russia as part of an overnight campaign targeting the country's military and industrial infrastructure, Ukraine's General Staff reported on 2 August.

The military said the operation was carried out overnight on 2 August as part of efforts to reduce Russia's military and economic potential to wage war against Ukraine. These long-range strikes are intended to disrupt fuel supplies, strategic aviation, drone operations, and logistics supporting Russia's invasion.

The reported attacks are part of Ukraine's sustained campaign of deep strikes inside Russia, which has increasingly targeted oil refineries, fuel depots, airbases, ammunition storage sites, defense industry facilities, and drone infrastructure. These facilities directly support Russia's war effort and are therefore legitimate military targets. 

Saratov refinery and Engels airbase targeted

According to the General Staff, Ukrainian forces struck the Saratov Oil Refinery in Russia's Saratov Oblast, causing a fire at the facility.

The military described the refinery as one of the largest in Russia's Volga region, with an annual processing capacity of around 7 million metric tons of crude oil. It said the plant helps supply fuel to Russia's military-industrial complex and armed forces.

The extent of the damage is still being assessed.

Ukraine also reported striking Russia's Engels airbase in Saratov Oblast, with a fire breaking out after the attack.

The Engels base is one of Russia's main strategic aviation hubs, hosting Tu-95MS and Tu-160 long-range bombers that have repeatedly launched cruise missile attacks against Ukrainian cities and infrastructure since the start of the full-scale invasion. 

The airbase has been targeted by Ukrainian long-range strikes on multiple previous occasions in an effort to complicate Russia's strategic aviation operations.

Fuel depot and drone infrastructure hit

In Kaluga Oblast, Ukrainian forces said they struck the Lyudinovo oil depot, which the General Staff said is used to store and supply fuel and lubricants for the Russian military.

The overnight operation also targeted a site used to store, prepare, and launch attack drones near Navlya in Russia's Bryansk Oblast, according to the statement.

Ukraine has increasingly focused on Russian drone infrastructure as Moscow expands its use of long-range Shahed-type attack drones and domestically produced variants in near-nightly attacks on Ukrainian cities.

Drone command posts struck a day earlier

Separately, the General Staff said Ukrainian forces struck Russian drone command posts on 1 August near Olkhozhemchuhova in Russia's Kursk Oblast, as well as near Berestok in occupied Donetsk Oblast, Sichneve in Dnipropetrovsk Oblast, and Yablukove in occupied Zaporizhzhia Oblast.

The military said it would continue conducting operations aimed at degrading Russia's ability to sustain its armed aggression against Ukraine.
