More intimidation than efficiency: Forbes about the strikes
Usually Fab-500 with the UMPC flies about 60 km. Obviously, FAB-3000 aircraft is not so aerodynamic and will have a shorter range. The huge shells in both cases were not struck directly. According to the Russian Telegram-channel FighterBomber, conducted by PCS pilot Ilya Tumanov, the explosive wave reaches 180 meters, and fragments fly more than 1000 meters. Tumanov himself assumes that two bombs Fab-1500 would be more effective in one Fab-3000.
Su-34 can also carry only one Fab-3000 bomb instead of three Fab-1500, and the front bomber itself loses significantly in maneuverability. The power of the explosive is geometrically independent on the weight of the bomb. Therefore, in essence Fab-3000 is a little more powerful than Fab-1500. Therefore, even the occupier Tumanov himself believes that it would be more effective to beat three Fab-1500 than one Fab-3000. However, for someone, there will be awards for creating a miracle weapon.
