By last week, the evidence of a new and sustained attack against a crucial part of Russia’s economy was impossible to ignore. On Wednesday, a drone hit the Tuapse oil refinery in southern Russia on the Black Sea. Flames from the burning refinery were visible above an inky skyline. Nearby, the airport in Sochi – Putin’s favourite resort, famed for its pebble beaches – was forced to close.
So far this year, Ukrainian drones have struck at least four Russian oil and gas terminals across the country. The attacks are part of a growing asymmetrical campaign by Kyiv to cripple the industry and to deprive Moscow of the billions of dollars in global revenue it uses to fund its war. About half of Russia’s $420bn export earnings last year came from oil.
Modern equipment was available this time. Besides, I’m willing to bet those drones cost a lot less than replacement refinery parts when you have to avoid the sanctions.
And adding to your argument; I believe most refinaries were maintened by Western expertise and replacements were supplied by Western firms, but both aren’t happening anymore (like with the airplanes)
So yeah, I agree, these drones are doing damage for sure.
also even if no damage was done russia now needs to move air defense from the frontline back to targets in russia to prevent more attacks.
Also in the best case the hit forces the rafinery to completely shut down costing russia a lot of money until it can restart to produce.
