The Lockheed SR-71 Blackbird was a revolutionary aircraft designed for high-speed, high-altitude reconnaissance missions.
Developed by Lockheed's Skunk Works division, it first took flight on December 22, 1964, and entered operational service in 1966.
The SR-71 was specifically crafted to outpace threats, achieving incredible speeds up to Mach 3.3, which translates to around 3,529 kilometers per hour (2,193 miles per hour).
This iconic aircraft could soar at altitudes over 85,000 feet (approximately 25,900 meters), allowing it to evade enemy missiles and radar during reconnaissance missions.
