[quote]Four years after revealing plans to develop a Mach 6 strike and reconnaissance aircraft, Lockheed Martin says hypersonic technologies are now sufficiently mature to enable progress towards a flight demonstrator.
The company’s secretive Skunk Works unit has been working since at least the early 2000s on the basic building blocks for an operational hypersonic vehicle and in 2013 revealed to Aviation Week it was developing a scaled demonstrator for the SR-72, a proposed successor to the U.S. Air Force’s long-retired Mach 3 SR-71 Blackbird spy plane.  However, details on any subsequent progress have been scarce since this initial plan was unveiled.

“We’ve been saying hypersonics is two years away for the last 20 years, but all I can say is the technology is mature and we, along with Darpa and the services, are working hard to get that capability into the hands of our warfighters as soon as possible,” says Rob Weiss, Lockheed Martin’s executive vice president and general manager for Advanced Development Programs.(...)[/quote]
