Reminder: though I doubt feasbility of building gliding kit for FAB-5000, Tu-22M3 have 3 external hardpoints each rated for 6t Kh-22 missile. Therefore 3x FAB-1500 for Su-34 and 3x FAB-3000/5000 for Tu-22M3 would be ..well, intriguing. In any case, Russians would do well if at least 1500/3000/5000 had been fitted with somewhat more aerodynamic, composite tails and noses and even simplistic, image based terminal guidance. PS: remember, that in WW II Allies used "Grand Slam" bombs slightly OFF targer ON PURPOSE, to use ground conducted shockwave - particularly effective against bridges.
There's also FAB 3000
