To not go too far off topic:
No, our Block-52's have CFT's but we haven't seen them yet.ACM mentioned that CFT's reduce maneuverability so they will only be used if there will be dire need .
If that would be the case, wouldn't they at least show them at the induction ceremony? Regarding the maneuverability, that is only the case if PAFs F16s normally uses only a centerline fuel tank in CAP for example. However, CFTs produce less drag than underwing fuel tanks and gives the advantage of a lower RCS, so if that is true, PAFs prefers maneuverability over lower RCS, which is interesting.
