You guys have UAVs as a mass offensive weapon because you are relatively lacking in that aspect with your Fighter planes which is a very iffy strategy because as we saw in Ukraine you need well established and dominant air surpeiority and it's kind of doubtful with their results.
Strange conclusion here, dont remember Turkey using drones as replacement for fighters, the only area where Turkey replaced fighters (not even completely) is asymetrical warfare. The F-16 and T-129 are still regularly flying missions into Iraq within the scope of ''claw'' operations.
Fighter are often way too expensive to use against terrorists and rag tags who have no air defence so drones are very handy, a squadron of TB-2s can monitor a whole region 24/7, give reconaissance and strike if necessary, for this purpose drones are way superior to any fighter that has only limited range and endurance in the air.
Other than that i dont remember Turkey using drones as a replacement for airforce, TF-X projects whole purpose is to elevate the airfoce into 21st century with as little dependance as possible, whether it will be success is another question, otherwise alternatives will come in place.
Drones have their place in the battlefield, they are not very capable against any state actors with a capable army for sure but that was never the intention to begin with, yet even then they can be useful if the enemy lacks certain capabilites, Russians know exactly what i am talking about, they became TB-2 experts in recent years.
