Inside the fighter jet, the F22 and F35 are out of the question, but the F15, F16, and F/A-18 are now opportunities lying before Yang Yi. The choice is also in front of him.
If possible, Yang Yi would really like to try everything, but he knows it's impossible, and understands the principle of not biting off more than one can chew, so at most two models, only two models. Any more would truly be unmanageable.
There's no need to choose a transport plane, but it's really hard to choose a fighter jet.
Especially since the F15 is mainly used now as a strike fighter, rather than as the air superiority fighter it was designed to be. The F15E has become the most used bomber in the United States Air Force. But what about the F16? Although it can also be used as a strike fighter, its potential for modifications as a strike bomber is ultimately not as great as the F15, a twin-engine heavy fighter, and it's more often used as a pure fighter.
