If Turkey want's to have a chance in drone market that drone has to be below $15mln (which is still twice the price of a comparable Chinese drone)
It is not entirely about the price in the International Market. Lobbying, financing (crediting) for an order is more crucial, Chinese offers long term credits with low interest, sometimes extending up to 10 years for a few million dollars.
There has been another case as well, which Turkey made a lower bid again with a limited ToT and local production for future orders yet the country has clinged on more expensive US product with a restricted use (without arms only ISR under supervision of US personnel), which eventually wasn't sold them either and later they turned their point towards China and acquired some.
On the above case, Turkey again has made nearly as same as, yet more expensive, Chinese on the same basis (training, spare parts, munitions included), also with more extend of local production for future orders yet still failed against them because Chinese has lobbied perfectly using some tools.
It makes no sense to have a drone at half price of a fighter jet. Your citing of US drones are completely wrong, the US uses her position in Nato to push their weapons upon "allies", utilizing CAATSA treaths.
Cost of a Drone = Cost of a drone + Operational cost + maintenance cost
Cost of a Jet = Cost of a Jet +Operational cost + maintenance cost + Cost of the Pilot Training * percentage of risk
A drone can be replaced in 2 weeks or within a week, no stress on operator/pilots upon a loss
A jet fighter can be replaced in some months, pilot replaced in 5+ years or more
A jet crashes, you have to extract the pilot and make sure if he was KIA
A drone crashes, bomb the location with artillery - rocket artillery and leave it.
I would only object if a company is abusing the above reasons and selling expensive products in return of huge profits if profits are within an acceptable margin there is no other way i think.
