Yep, apparently Ukraine still cannot affect fuel production in Russia to any significant point. Drones with less than 100 kg of explosives do not do particularly significant damage. One really need to deliver like a ton or more of explosives and for that one needs bombers that can penetrate air defenses or very expensive stealth cruise missiles or big ballistic missiles.
Hah. Ukraine has cut Russian petroleum production 40%...
Ukraine dramatically reduced Russian fuel export revenue, and the sanctions did so even more.
It was really coming to the point of urgent existential threat to the Putin regime this spring, before Trump and Netanyahu bailed him out, first by doubling the global oil price and then by relaxing sanctions.
And Ukraine's drone / cruise missile portfolio includes things like the Flamingo, more than twice the payload and range of a Tomahawk.
I’m surprised that they are not dropping thermite on oil refineries. Most things there will burn if hit enough.
Of course it has had a significant impact. The reason Russia has repeatedly turned off fuel exports every couple of months for the past couple of years despite high global prices because Ukraine keeps disabling enough of their refining capability to cause shortages.
