Summary ATAC has a vast fleet of private military aircraft, including Mirage F1s, Hawker Hunters, Kfirs, and L-39 Albatroses. ATAC purchased the French Air Force's entire legacy fleet of 63 Mirage F1s in 2017, forming the backbone of its missions. ATAC is the world's largest outsourced civilian military fleet, operating in various locations worldwide for tactical flight training.

While the US Air Force may provide much of its own training , it also contracts out to private companies like Airborne Tactical Advance Company (ATAC) for tactical flight training roles. ATAC has been owned by the conglomerate Textron since 2016. ATAC has contracts with the US Forces, US Marines, the US Navy, the US Army, and international forces.

Air Force training is complicated, and full-time flight training takes 2 to 3 years after graduate school.
