That's right, but selling the old TB2s 20-30 for Good Price every 5-6 months really makes sense.Tb2 will after 20 years still relevant like it is now and Turkish Armed Forces will use it to. They are cheap and ther is enough spare parts to let it fly years.
You could also sell it back to Baykar and they can resell it as refurbished to other Countries.
As far as I know, Turkey has about 200-300 TB2 drones in total.
With the money you can invest in TB3 & TB2T AI, you invest it in your own industry & ecosystem and not in a foreign industry, you secure jobs and the money circulates in the country.
You also modernize the armed forces with better next generation low cost drones.
