Also known as the "Blackbird," the SR-71 was developed as a long-range, high altitude, strategic reconnaissance aircraft.
Flying at a maximum speed of 2,200 miles per hour, the "Blackbird" is one of the fastest jets ever to take to the skies. Developed and built at Lockheed Martin's super-secret "Skunk Works" testing facility, this revolutionary aircraft entered operational service in 1966.
Measuring just over 107 feet in length, the SR-71 has a total wingspan of fifty-five feet, seven inches. Capable of climbing at a rate of more than 1,100 feet per minute, it maintains a service ceiling well above 85,000 feet, enabling it to successfully execute its vital reconnaissance missions.
