A jet that intercepted an SR-71 Blackbird

The incident involving the Viggen and the SR-71 was not merely a demonstration of raw speed; it highlighted the effectiveness of the Swedish air defense strategy. The Viggen was equipped with advanced radar and fire control systems, which allowed it to provide effective surveillance and targeting even in the face of daunting adversaries. Specifically, its PS-37/A radar system proved to be formidable, offering both search and tracking capabilities in a compact design suited for a small nation like Sweden, which required a flexible and mobile air defense solution.
