Global Times reported on an intention that the Director of Rostec (the Russian State Corporation for Assistance to Development, Production and Export of Advanced Technology Industrial Products, formally known as Russian Technologies) recently announced. Russia is ready to “provide technical help at any time” to Turkey to develop its own fifth-generation fighter jets. Russia obtained rich experience during its development of the Russian Su-57 fifth-generation fighter jets. Russia has been delivering its S-400 air-defense missile systems to Turkey since July, which caused a relationship crisis between Turkey and the United States. Turkey plans to deploy the S-400 systems in April, 2020. Washington has delayed its delivery of F-35 fighter jets to Turkey and threatened to cancel the F-35 contract with Turkey altogether. The United States asked Turkey to give up the use of the S-400 systems, but Turkey so far has resisted.
