The Lockheed Martin SR-72 is a conceptualized unmanned, hypersonic aircraft intended for intelligence, surveillance and reconnaissance proposed by Lockheed Martin to succeed the retired SR-71 Blackbird. The Lockheed SR-71 Blackbird has been overtaken by it’s successor, The SR-72, the fastest Aircraft ever built. According to Lockheed Martin’s Skunk Works, the SR-72, has a twin-engine aircraft which is designed in such a way that it can fly at Mach 6. By 2018, the SR-72 could be up for demonstration showing off at the high-speed strike weapon (HSSW), a U.S. hypersonic missile program taking shape under the Air Force and Darpa.
