EAF blk 52 will be big if , or the other hand EDA blk 42 will be possible if we can affordPAF would prefer PW powered airframes for V update so likely try to procure Blk 42 EDA to upgrade due to familiarity with the powerplant.
Ideally get the 20 odd BLK 52 from EAF if they are willing to part with them. Those once upgraded will be classified as V/Blk72.
New built aircraft will only be GE F110 powered Blk 70.
