As far as I'm aware their guided 1500's can be carried on all of their modern Multirole platforms. Wouldnt make a lot of sense to use guided munitions in this fashion though surely?
Good point, I'd forgotten about the guided bombs as the RuAF doesn't seem to have many but the the KAB-1500L (3300lb Laser Guided bomb) can be fitted on the Su-34/35 which would make sense over the aircraft type. I wonder if the Russians were monitoring the phone of someone in the Ukraine military etc and decided that, if they made a call from the hospital, that building must have actually been a command post/storage etc rather than a hospital and added it to the target list. It'd make sense as to why the RuAF may have dropped a fairly specialised bomb if they thought the target was something important.
