asking from grok with feature using search all over from internet about "Utilization of AIM-120C-8 Maximum Range by MLU and block 52 radars i.e. AN/APG-66(V)2A and AN/APG-68(V)9, i got the following response
No, neither variant can fully utilize the AIM-120C-8's maximum range due to radar limitations. The radars' detection/illumination ranges (74 km for MLU, 104 km for Block 52+) are well below the missile's potential, limiting launches to shorter distances where the target can be reliably tracked and illuminated (typically 50-80 km for MLU and 70-100 km for Block 52+).
