This new plane is a hypersonic weapon delivery drone, barely related to the SR-71 aside from the speed it can travel.

As to the sixty years thing, satellites made spyplanes nearly entirely obsolete and traditional aircraft with stealth technology covered the remaining cases well enough that there wasn't a need for more speed. Research went into making missiles better instead, and this is designed to be a launch platform for those missiles.
