From USAF website:
Once you are qualified to join the Air Force as an officer, you will take this path to get your wings:
- Complete Officer Training (Air Force Academy, AFROTC, or OTS).
- Enter Undergraduate Pilot Training (UPT) and begin flight training (~1 year).
- Nearing completion of UPT, you will be assigned an aircraft, which is called getting your seat assignment. Seat assignment is determined by class ranking, training performance reports, instructor recommendations, your aircraft preferences and our needs.
- Upon completion of UPT and your seat assignment, you continue flight training for the specific aircraft you were assigned (six months to one year).
- Nearing completion of your Advanced Flight Training, you will be given a squadron and location assignment. Your location preferences are considered.
You would then arrive at your new SQN, as a very junior pilot. You then have to learn each task, wingman, leader, 3 aircraft wingman, leader, 6 aircraft, and so on. Then you learn Air to air guns, then each missile, then air to ground.
Takes years. Of course if a war started your off, and you learn on the job, or you die.
