Demilitarizator brings together the key facts about the Yaroslavl refinery strike and the latest results reported by Ukraine’s defence forces.
Strike on the Slavneft-YANOS refinery in Yaroslavl
Explosions were heard in Yaroslavl during the night of 3 November. A fire broke out on the refinery’s premises after the attack.
Slavneft-YANOS, whose full name is Slavneft-Yaroslavnefteorgsintez, is one of Russia’s largest oil refineries. The plant processes around 15 million tonnes of crude oil a year, producing petrol, diesel, aviation fuel and lubricants.
Such plants matter to Russian military logistics because the armed forces need refined products: fuel for aircraft, vehicles and armoured equipment. Crude oil production alone cannot meet those needs.
Russia’s daily losses: the General Staff’s morning update
According to the Ukrainian General Staff’s morning update on 3 November, Russian personnel losses on 2 November were estimated at 2,060.
Equipment losses over the day also included:
- four armoured fighting vehicles;
- 39 artillery systems and one multiple-launch rocket system;
- one heavy flamethrower system;
- four unmanned ground systems;
- 1,413 UAVs;
- 363 vehicles and four items of specialist equipment.
There were 206 combat engagements along the front during this period.
Ukraine’s Unmanned Systems Forces: 2,208 targets hit
In its report published on 3 November, Ukraine’s Unmanned Systems Forces grouping reported 2,208 enemy targets hit on 2 November.
The results included 685 Russian personnel hit, of whom 287 were killed. The grouping also hit:
- 58 Russian drone launch points;
- 29 radar, electronic intelligence, electronic warfare and communications systems;
- 107 vehicles and items of specialist and engineering equipment;
- 16 artillery systems;
- 16 storage sites;
- 363 UAVs.
Over the first two days of November, the grouping hit 4,228 targets, including 1,393 enemy personnel.
Today’s report covers two areas of Ukraine’s defence effort: strikes on the industry that supplies Russia with fuel, and the destruction of troops, equipment and command assets at the front.
