Lockheed Martin has begun work on a successor to the supersonic Blackbird SR-71 spy plane.
The unmanned SR-72 will use an engine that combines a turbine and a ramjet to reach its top speed of Mach 6 - about 3,600mph (5,800km/h).
Like its predecessor, the SR-72 will be designed for high-altitude surveillance but might also be fitted with weapons to strike targets.
Lockheed said the aircraft should be operational by 2030.
I presume some of the R&D will coming to Bedfordshire.
Jobs for the next 10 - 15 years :)
