The McDonnell F-101 Voodoo was a supersonic jet fighter and reconnaissance aircraft used by the United States Air Force during the Cold War. Designed in the 1950s, it was known for its sleek design and powerful engines, allowing it to reach speeds over Mach 1. The Voodoo served primarily as a long-range interceptor and was equipped with advanced radar and weapon systems for its time. The F-101 Voodoo played a significant role in various military operations and was also used by the Royal Canadian Air Force. It was eventually retired in the late 1970s, replaced by more advanced aircraft like the McDonnell Douglas F-4 Phantom II.
