Huh, weird. The empty mass is 16300 kg for S and 16700 for SM. I though the difference IRL was much bigger (don’t know where I read it, but some sources would give only a small difference, select few of others would give a much bigger figure).
Oh boy, one FAB-3000 UMPK is enough to destroy one base and it glides very good. Su-34 can destroy 3 bases at once with six Grom-2s and FAB-3000 UMPK+two R-77s+two R-73s loadout.
I just tested it — I dropped the bomb from an altitude of 11,000 meters at a speed of 680 km/h, and it hit a target 43 km away. It still had enough altitude to glide even further.
Missiles can behave differently depending on the server. They always fly much better/smoother when it test drives, because the game’s server is on your PC. In live games they behave worse.
I don’t know if a lighter server (dev server) increases the quality of missile simulation, but if it does that could be the reason.
Or, they did actually make them better by changing something under the hood. In the case, all TVC missile will fly be better (MICA, SRAAM, R-73).
