Over at the Skunk Works, aircraft designers are hard at work cooking up a hypersonic scion to the legendary SR-71, the superspeedy recon jet of the Cold War. November 1, 2013 10:21 AM PDT Zoom!

That's the big, jawdropping takeaway from Aviation Week's exclusive look at Lockheed Martin's work on the next-generation aircraft. A demonstrator version of the SR-72 could be ready as early as 2018. Lockheed told Aviation Week that the goal is for the new aircraft to be seriously hypersonic, blazing across the sky at around Mach 6. The intent, too, is to broaden the mission: the SR-72 would pick up where the Blackbird left off in performing high-altitude intelligence, surveillance, and reconnaissance missions, but unlike its weaponless predecessor also would -- hypothetically -- be capable of carrying out strikes on targets. To achieve those crazy-fast speeds, Lockheed's Skunk Works unit plans to integrate an off-the-shelf, fighter jet turbine with an air-breathing scramjet, building off the Pentagon's experimental Hypersonic Technology Vehicle (HTV) efforts, according to Aviation Week.
