When it comes to radar signature, whichever jet uses radar is going to be detected well beyond its own radar range and become a target; SPECTRA will give Rafale firing solution with 1* precision at 200 km. Rafale will have RCS of 0,75-1,10 m2 with 6 missiles, while AN/APG-81 has 160 km range vs 1 m2 target. Thus F-35 will detect Rafale at 149-164 km. Tracking (attack) range will be 119-131 km without jamming, or 22-25 km with jamming; 70-80 km is possible with EOTS. However, since SPECTRA can reduce Rafale’s RCS by factor of 1,5-3, F-35 will detect Rafale at 113-149 km; tracking range will be 90-149 km, with tracking range of 13-119 km. F-35 has RCS of 0,00143 m2 with 4 missiles, while RBE-2 PESA has 139 km range vs 5 m2 target. RBE-2 AESA (which entered service in 2012) has 208 km range vs 5 m2 target, or 278 km when cued by SPECTRA. Detection range will be 18 km for RBE-2 PESA and 27 km for RBE-2 AESA, with 36 km possible if RBE-2 AESA is cued by SPECTRA. This will give attack ranges of 14 km, 22 km or 29 km. Rafale’s OSF has range of 80 km vs subsonic head-on target at 20.000 ft. At 30.000 ft, range may be 80-90 km, which means that Rafale will be able to attack the F-35 from 65-70 km. That being said, ability of both to attack the opponent will be limited by missile effective range (15-100 km for Meteor, 9-36 km for AIM-120D, 4-16 km for MICA).
