Detailed Summary
Operation Highjump was a large-scale U.S. Navy operation led by Rear Admiral Richard E. Byrd in Antarctica from August 1946 to February 1947. The mission's goals were to establish the Antarctic research base "Little America IV," train personnel in cold-weather operations, and explore the feasibility of permanent bases in the region. Despite its official objectives, the operation has been the subject of numerous conspiracy theories, including allegations of secret battles with Nazi forces and encounters with UFOs, though these claims lack credible evidence.
