This is the successor to the SR-71 Blackbird, and it is gorgeous

The SR-72 is being designed with strike capability in mind. “We would envision a role with over-flight ISR, as well as missiles,” Leland says. Being launched from a Mach 6 platform, the weapons would not require a booster, significantly reducing weight. The higher speed of the SR-72 would also give it the ability to detect and strike more agile targets. “Even with the -SR-71, at Mach 3, there was still time to notify that the plane was coming, but at Mach 6, there is no reaction time to hide a mobile target. It is unavoidable ISR,” he adds.

The jet accelerates by way of a two-part system. A conventional jet turbine helps boost the aircraft up to Mach 3, at which point a specialized ramjet takes over and pushes the plane even faster into hypersonic mode.

From Lockheed's mock-ups, there doesn't appear to be a bubble for the pilot — which suggests a windowless cockpit or fantasies about a future unmanned version of the plane. But let's not get ahead of ourselves.
