The Mikoyan MiG-41 is an interceptor-fighter aircraft currently being developed for the Russian Air Force by Mikoyan.Not much information is available concerning this project, but it is rumored that the aircraft will be extremely fast (with a top speed of Mach 4 to 4.3).It is anticipated that it will not enter service until at least 2020 and expected to achieve near hypersonic speed. As an interceptor, its primary mission is rumoured to offset future reconnaissance aircraft currently being developed by the United States and China (although Russia is also developing such aircraft, such as the Ayaks).To achieve such high speeds, the aircraft is probably to be equipped with ramjet- or turboramjet engines.
