We should already be 5 years into transitioning into pilotless aircraft and a large inexpensive drone air force of all kinds of craft from fighters and bombers to even tankers and surveillance. Making multimillion dollar fighters that need a human pilot are so very close to obsolete.
Fighters will not become obsolete as long as there no tech solution for unbreakable and unjammable control signals.
Maybe using Starlink’s satellite laser communication with a drone would come close but then there is cloud cover and the sensing of the lasers to contend with.
