If such are true however future clients of S-400 which does not desire Chinese components would need to add it in contract. This will of course drive the cost up for the system as Russians would need to indeginize those components.
The head of the Kronstadt company: the Turkish Bayraktar would not have passed state tests in Russia
Now everyone is comparing our "Orion" with the Turkish "Bayraktar". But if "Bayraktar" had been created in Russia, it would not have passed state tests according to our requirements. In our "Orion" we are sure - it surpasses the Turkish colleague in many respects. We prefer not to talk about how to "catch up and overtake America," but to act. Therefore, we develop and manufacture drones and, in fact, together with our customer represented by the Ministry of Defense, we are creating a completely new aviation sub-sector. We hope that the international market will appreciate it.
Russian Aircraft Corporation MiG and Aviadvigatel have confirmed that work continues on “radical modernization” of the MiG-31 Foxhound, with the focus on extending the performance of the aging, out-of-production Mach 3 interceptor so that it can carry out not only air-defense duties but also serve the recently established VKO, the Russian acronym for the country's Air and Space Defense (Command). Under a directive from the Russian defense ministry, RAC MiG is working on new versions of the aircraft more capable than the current MiG-31BM.
The 79M6 missile with a mass of 4550 kg took off from under the MiG-31D flying at a speed of Ma = 2.55 at an altitude of 22 km and continued to the target at an altitude of 120 to 600 km, depending on the distance. The flight time of the rocket was from 100 to 380 s. The satellite was destroyed by a direct hit or with a 20 kg explosive charge. The target of the MiG-31 was indicated by the 45Ż6 Krona ground system consisting of a decimeter and centimeter radar with electronic scanning and an optical-laser locator and rangefinder; information was transmitted on board the aircraft via the 46I6 radio link.
Really? Russia bought S-400 radar components from China?
