ToT is totally related with the politic relations of states. NATO is not a bargain issue on defence trades but just encourage members to trade among each-other. Tenders are being opened to announce what you are requesting from manufacturer and The companies who is willing to accept the terms, just attend tenders to provide their offer. That's the standart procedure to be clear to your public in every democratic states. Not only NATO members, but also Non-NATO states are purchasing Turkish papers to give their offers. There are many examples like that Turkey has canalized sources to non-NATO states since they accepted requests with giving better offer. Those things could be made by all states including Saudi Arabia but It is at least about bargain power of states tied with politic stability. While EU is accusing you in order to violating human rights and issues arm embargo, In this politic circulation, You can not demand much things from USA. There is no chance remained for you to acquire Western equipment.
Contrary to what you say, NATO member Turkey is under a hidden embargo on sub-component/component level since tens of years. It is because of their politic calculations to protect Greece, Cyprus and Armenia like states and to keep Turkey inside of their hands politically/militarily. I don't know whether you are aware of Turkey's defence relation history with our NATO "allies" but Let me summarize a few things from past.
-Turkey is a NATO state that USA made 230mm artillery rockets are exported us with restricted numbers. When addition package is requested to order, It is refused so Turkey has developed own artillery rocket systems with China in 1990's and improved technology years by years and today, We are offering 107mm, 122mm, 230mm, 302mm, 600mm, 610mm precision strike artillery rocket/missile family. No need to mention ballistic missile programs kept hidden for now.
-Turkey had selected AH-1Z attack helicopter and It was planned to purchase 145 of them. Let transferring technology aside, USA refused a simple integration for Turkish components. Turkish side tried to convince USA but They didn't step back politically so Tender is cancelled. Today, Thanks to Italian help (Berlusconi factor)Turkish industry is manufacturing both attack and utility helicopters from transmission to rotor, turbo-shaft engine, fuselage, avionics to missiles.
-Tank-2000 project, It was KMW selected with their Leopard-2A6EX variant. It was planned to order 1000 tanks but Germany blocked the deal and It is also cancelled. Turkey started working over tank technology and It was Non-NATO state Israel willing to share their technology with Turkey. With Sabra project, Turkey has worked over tank FCS technology and developed a domestic one called Volkan. Leopard-1 tanks have been upgraded with Volkan FCS. Later more advanced variants, and Altay tank appeared.
I can tell pages of such events about Western embargoes over Turkey for engines, laser pointers, UAV, missile, helicopter, sonar, detector, transducers, radar issues but Thanks Allah that We have been revealing a new thing whenever they wanted to block our advancements. That's the way We comprehend actual meaning of NATO for Turkish people. Your NATO perception is not valid for Turkish Republic at least.
