I wonder when we will see dedicated drones or drone ordenance for this. It seems like using baba yaga at night to plant a few shaped charges is also an option
Targets like this are unlikely to ever be serviced by drones like Baba Yaga. This looks like multiple 1000lbs glide bomb hits, the Baba Yaga can carry 33lbs. By the time you have built the capacity to deliver powerful explosive force like this remotely you've already crossed from cheap drones to ballistic and cruise missiles. Most of the long range drones in use by Ukraine are carrying 40kg warheads. Cheap solutions just don't have the hitting power, and by the time they are scaled up, they're just the old expensive solutions.
I'm talking a 30lb shaped charge designed to take out a bridge deck. That's a lot of explosive power. But indeed it's maybe not the most practical approach. If they have better things to do for baba yaga.
