Turning Point: Fall of Liberty
In TP:FOL timeline, the United States still does not have jet fighters. The use primitive fighters compared to the Germans like the P-47 thunderbolt, P-40 Warhawk, P-51 Mustangs, and the F4U Corsair. The Air Force is not really seen in game but in screenshots or some trailers, downed U.S. planes in the Harbor. This means that they were quickly taken out if they didn't win in a dogfight. Seeing that they also use the SBD Dauntless also means that their planes can't dogfight.
