You can invest more on the one platform you have and take every pilot and every engineer in to top shape and the plane itself with continuous development rather than losing time with special training planes and you are better off. I know it hasn't been like this so far, I can tell you that as I have my earliest picture taken with a cadet trainer decades ago but the future may be different. You will have a much larger pool of candidates to choose pilots from as planes come with simplified operation interfaces that are way easier to command and master. A smart plane may also be requiring lesser hours to train with to get into top shape. Dog fighting is to become a thing of the past too. There is a similar situation in the civilian aviation too, simplified operations until planes become fully uncrewed.Not with the flighthours training squadrons incur over time. They start sorties in early morning, fly until 4-5. spend a day close to Çiğli, you'll see at least 50-70 sorties a day every weekday, KT-1s and T-38s. Combat squadrons don't make one third of the sorties training squadrons make. No wonder 121's mascot is a bee, they are truly like working bees. If we ran the combat aircraft with similar sortie numbers, they'd reach their airframe limits within a few years.
