also i just read some early speculation (april or may?) that the tu-22m3 is simply too valuable to drop glide bombs in so close to patryot country. the same article made it clear that the fab-3000 is "theoretically" can fit on su-34 center pylon (they are assume that the plan can lift 4 tons here) but the umpk wings must be reinforced and packed tightly. russians solved this since. if i recall correctly the maximum launching speed was 1900km/h, and the very best new version umpk for the fab-500 have much larger optimized wings for 90-100km range!
