I believe the Mirage F1C is no longer suitable to remain at a BR of 11.3.
In Air RB mode, multi-path clutter has been weakened, which means the threat from AIM-7F and AIM-54A/C missiles has further increased. The Mirage F1C has to perform more maneuvers to evade missiles, and its weak engine and poor energy retention make its performance even worse. This change also means that the threat posed by the Mirage F1C’s Super 530F missiles has further decreased since everyone carries chaff, which disrupts the Super 530F with 100% effectiveness.
Both the Mirage F1C and F1C-200 use outdated RWRs. You cannot accurately know who fired the incoming missile, what type of missile it is, or sometimes the RWR won’t alert you at all.
The Mirage F1C’s only real threat to enemies are the two Magic 2 missiles with a range of 2 km, while the F-4S can carry up to six AIM-7F missiles that can be fired head-on at 10 km, or five AIM-7F missiles plus two AIM-9H missiles. All F-4S missiles can be guided by the helmet-mounted sight, which further increases the F-4S’s suppression over the Mirage F1C. Even if the Mirage F1C evades all AIM-7F missiles, after evading, it will be left without altitude and speed, making it easy to kill.
Additionally, with both carrying 20 minutes of fuel, the F-4S has a thrust-to-weight ratio that is 0.2 higher than the Mirage F1C! The F1C can hardly win an energy fight against the F-4S.
I believe a BR of 11.0 is reasonable for the Mirage F1C; 11.3 is too high.
In Ground RB, the Mirage F1C’s outdated RWR makes it difficult to avoid SPAA, and it might not even be aware of their presence.
The Mirage F1C also has a low payload capacity. For example, the F-4S can carry 24 500 lb SAMP Mk 82 bombs, while the Mirage F1C can only carry 5. The F-4S can also carry 60 Zuni Mk32 Mod 0 ATAP rockets, which allow for efficient and precise CAS, whereas the Mirage F1C lacks such payload options.
I believe the Mirage F1C’s BR in Ground RB can be lowered to 10.3. Compared to the Su-22M3 of the same BR, it has better all-aspect missiles, but only one-third the quantity, worse thrust, but more countermeasures. Overall, it’s balanced.
