Performance of the Tu-2000 and MiG-2000 projects compared to that of NASP

[Vahe231991]

I wanted to ask what advantages or disadvantages the Tupolev Tu-2000 and Mikoyan-Gurevich MiG-2000 HOTOL spaceplane projects had compared to the X-30/NASP spaceplane in terms of specific impulse, fuel-to-weight ratio, power-to-weight ratio, payload, and orbital maneuverability.

Not possible.  They were not far enough into design process define those parameters.
