Welcome to Warbird Wednesday! Today we’re visiting the Lockheed Martin concept plane SR-72 used in “Top Gun: Maverick” as Darkstar. The SR-72 is a successor of the retired SR-71 Blackbird and is a Hypersonic optionally manned aircraft with the purpose of intelligence, surveillance and reconnaissance. Lockheed Martin expects that the SR-72, which can reach speeds in excess of Mach 6, could fly by 2025.
