US aerospace company Lockheed Martin is reviewing aircraft overhaul ideas.
Lockheed Martin provided instructions for revisiting the idea the SR-71 hypersonic aircraft.
Lockheed Martin is reportedly looking at upgrading the latest version of the SR-71 aircraft.
The SR-71 was designed in response to the shooting down of a US U-2 spy plane in 1960.
The US government wants the aircraft to conduct surveillance at a high enough altitude and speed to avoid missile attacks.
After years of retirement, the SR-71 aircraft will now be developed into its newest generation, the S.R. 72.
The SR-72, also known as the Son of Blackbird, is a hypersonic unmanned aerial vehicle (UAV) concept currently being developed by Lockheed Martin's Skunk Works.
