I saw an article about the Bayraktar drone. Just about anything but the frame was build outside Turkey. Engine, fuel pump, surveilience and target system, radio transmitter, copy of bomb rack, thermal batteries for smart micro monition, radar altimeter, fuel filter, navigation radio, GPS reciever, airborne modem to transfer video, various chips, antenna.. the list was long.
Its impossible to manufacture anything modern without foreign parts. We all specialize in something, and put together you have something like a drone. Russian drones is a mix of US, EU and Asian parts too.
My guess is that Turkey rely on imported parts.
