The sea hawk is a very slow aircraft that was actually quite balanced at 8.0, at 8.3 it makes absolute 0 sense, it has no reason being the dame br as the mig15bis and at a higher br than the mig15bis ish.
The tt non missile one should be 7.7, the missile ones should be 8.0
The sea hawk should not be able to face f104s or f106s
