Saw this amazing soviet designed bomber back in the late 50's. Although it never got off the drawing board, its clear to see the advanced concept of Soviet designers way back in the 50's. But it was killed of by the Soviet ICBM development.
Plus except the engines, it does look stealthy too. It must have produced a smaller RCS for its size had it flown.
As for new gen stealthy bomber with hypersonic speeds, it is possible to look into modifying this concept as it does look like a hypersonic design.
