It is a very ambitious plan for the Russian Ministry of Defense.
According to Russian officials, preparations for this aircraft have begun. Its development is part of the PAK DP program and is now in the concept stage.
If built, it will be a 6th generation aircraft and will be equipped with a ramjet or turboramjet engine. It will be able to develop speeds of 4 to 5 Mach (4 or 5 times the speed of sound). It will also have weapons to strike satellites and can fly close to space. It may also be able to strike a hypersonic rocket.
On the other hand, war analysts are concerned about whether Russia could develop such a weapon. But the Russians say it is not something that is impossible for them but something that will last a long time.
