4158 strataerospace wg. Elmendorf

The 4158th Strataerospace Wing was an experimental United States Air Force unit assigned to Elmendorf Air Force Base, Alaska, during the early 1960s. Established as part of the Air Force's response to Cold War tensions and the need for advanced high-altitude reconnaissance and interception capabilities, the wing operated a mix of cutting-edge aircraft, including early models of the SR-71 Blackbird and specialized interceptors. Its primary mission was to defend the northern approaches to North America and to conduct long-range reconnaissance over the Arctic and Soviet Far East. The unit was inactivated after a brief period as its unique mission set was integrated into other commands and advancements in technology made some of its roles redundant.
