The Lockheed Martin Skunk Works have finally announced the successor to the famous SR-71 Blackbird. The new spyplane, an unmanned drone called the SR-72, will perform intelligence, surveillance and reconnaissance missions like its forbearer, but unlike the Blackbird it may also perform a strike role. Using Aerojet Rocketdyne scramjets mated with standard military jet engines, the plane will cruise at hypersonic speeds up to Mach 6, almost doubling the SR-71's top speed of Mach 3.3.
