The Pratt & Whitney J58 was a jet engine that powered a long-range, Mach 3+ strategic reconnaissance aircraft operated by who?
Lockheed SR-71 Blackbird The Lockheed SR-71 "Blackbird" is a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by Lockheed and its Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. During aerial reconnaissance missions, the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch was detected, the standard evasive action was simply to accelerate and outfly the missile. The SR-71 was designed with a reduced radar cross-section.
George J. Mead George Jackson Mead (December 27, 1891 Everett, Massachusetts – January 20, 1949 Hartford, Connecticut) was an American aircraft engineer. He is best known as one of the chief founding team members, together with Frederick Rentschler, of Pratt & Whitney Aircraft. Mead and Rentschler left Wright Aeronautical with the plan to start their own aviation-related business; they founded Pratt & Whitney Aircraft in July 1925. Their first project was to build a new, large, air-cooled, radial aircraft engine of Mead's design, which soon came to be named the Wasp. The first Wasp model was the R-1340, and a large series of Wasp models and Hornet models followed. Mead, as Vice President of Engineering, was the head of engineering for Pratt & Whitney from 1925 to 1935. He later left Pratt & Whitney and its parent United Aircraft. He served as the president of the U.S. National Advisory Committee for Aeronautics (NACA), and he served as head of the aeronautical section of the National Defense Advisory Commission during World War II, as a manager in the U.S. government's war materiel production effort.
