Are you that fucking dense? They are strategic bombers, yes, that was their originally role. They have been used in a CAS role for the last 20 years also. A simple google search will provide the evidence if you don't believe what I've seen with my own eyes.
And it doesn't take many modifications. Most of the bombs dropped now are smart munitions.
And loitering is what B-52s were originally designed to do. Also, LOL at you for thinking the US considers 170k an hour expensive. We blow a 500 grand on a missile to kill a donkey often enough.
B-52s can come from a further away Air Base, IE, not one in Afghanistan, it can loiter in the air awaiting a mission, out of range of man portable SAMs, and carries WAY more munitions. Keep trying to pretend to know wtf you're talking about though because you sucked dick around Russia.
They do it so often, they are even doing training integration with allies.
Here, have another article talking about its CAS role.
