Lol... You seriously do not know how American or British works? You think they are so stupid to let Turkish has the know how to make a good gunship engine? Let me ask you why Turkish brag they have licensed produced American PWF100 engine for their F-16 for many years and yet they could not produced a good engine for their TFX or even produced a own of their high thrust turbofan. You really think the british and American will easily let u have all the know how? The so called licensed produced are nothing but assembly parts from US exported critical parts. The main core of the engine still need to import from USA with the remaining 70% parts produced by Turkish themselves. But what makes the engine so difficult to produce is the main core or rotorshaft which has to withstand the most critical temperature.
