It’s the deepest Ukrainian drone strike of the war, so far
A month after Ukraine began bombarding targets inside Russia with explosives-laden sports planes modified for remote flight, one of the do-it-yourself drones has struck an oil refinery in the city of Salavat, more than 800 miles from the front line of Russia’s wider war on Ukraine.
It is, by far, Ukraine’s longest-range raid—and an escalation of Ukraine’s deep-strike campaign targeting Russian refineries, factories and strategic military sites.
And it’s at least the fourth attempted deep strike involving Ukraine’s sport-plane drones. Videos shot by people on the ground in Salavat clearly depict the wide straight wings, fixed wheels and propeller that are typical of an inexpensive sport plane, the kind a middle-class pilot can build at home from a kit costing as little as $90,000.
Typically buried underground.
You… got a source for that?

Fifteen here. Underground tanks are not that common. They are a maintenance and environmental nightmare. But it would be nice if you could provide with any evidence other than “trust me bro”.

Underground salt plumes are some of the most efficient natural forms of liquid and gas storage.
So all you need to do to build a tank is to move your entire facility to where natural geology favors not building a tank?
That still says nothing about the prevalence of above ground vs underground tanks.
Large storage facilities are located where geology makes storing energy underground cheap.
Man, now you’re just moving goalposts. Did they blow up a refinery or whatever you’re cooking up in your head? It’s clear you’re not having an honest discourse here. Goodbye.
It’s not clear how much damage they did or if they even fully halted operations. Normally, you want to hit a facility like that more than once.
