The Lockheed SV-7 is a prototype military aircraft developed in the 1960s by Lockheed Corporation. Designed as a supersonic transport, it aimed to combine speed and efficiency for military applications. The aircraft featured advanced aerodynamics and was powered by two jet engines, allowing it to reach high speeds. Although the SV-7 showcased innovative technology, it never entered mass production. The project was ultimately canceled due to changing military needs and budget constraints. Despite this, the SV-7 remains a notable example of Lockheed's contributions to aerospace engineering during the Cold War era.
