Operation Highjump: The Mission That Started the UFO Age

World War II did not end quietly. It ended in fire. By the time the fighting stopped, the deadliest conflict in human history had claimed as many as 80 million lives. Entire cities lay in ruins. Much of Europe had been shattered. Hiroshima and Nagasaki had introduced a weapon so destructive that it changed warfare forever. But Germany had been chasing its own nightmares. Before the Third Reich collapsed, Nazi scientists had built the V-2 rocket, the first long-range guided ballistic missile ever used in war. They had put the Me-262 into the sky, the world's first operational jet fighter. They were experimenting with flying wings, advanced submarines, guided weapons, and technologies that seemed years ahead of their time. These were the so-called wonder weapons, the secret projects Hitler hoped would reverse the war before the Reich was crushed. Germany surrendered in May of 1945. Japan followed in September. The war was over. At least, that was the official story. In Berlin, Soviet forces claimed they had recovered what remained of Adolf Hitler. After the collapse of the Third Reich, the Nazi flag had fallen. Concentration camps had been liberated. The regime that had plunged much of the world into war had been destroyed. But not everyone connected to that regime vanished into a prison cell. Some escaped. Some disappeared. Some were recruited by the very nations that had just defeated Germany. Scientists, intelligence officers, engineers, and military specialists found new homes and new employers. The war was over, but the search for what remained of Nazi Germany was only the beginning. Just one year later, the United States Navy launched one of the largest Antarctic expeditions in history. Nearly 4,700 men, 13 ships, submarines, and an aircraft carrier were sent to the most remote continent on Earth. Officially, Operation High Jump was a training and mapping mission. The Navy said it wanted to test equipment in extreme cold, photograph unexplored territory, and learn how to operate in the polar south. But the timing was difficult to ignore. In 1938, Nazi Germany had already gone there. A German expedition aboard the aircraft support vessel Schwabenland pushed into the Queen Maud Land, a frozen region Norway had already claimed as its own. But the Germans did not arrive like ordinary explorers. They launched aircraft over the ice, photographed massive stretches of the continent, dropped swastika-marked clay markers from the sky, and gave the region a new name, New Schwabenland. To Norway, it was Queen Maud Land. To Hitler's Germany, it was territory waiting to be taken. So when the United States sent a naval force of this size to Antarctica only months after the war, people began asking a question the official explanation never put to rest. What were the Germans really doing in Antarctica in 1938? Why did Operation High Jump end months earlier than planned? What was the United States Navy really looking for at the bottom of the world? Let's try to find out. Hello, I'm Mike Joberg, Marine Corps veteran and filmmaker, and we will try to answer these questions on today's episode of Forgotten History. The beginning of the toughest 26 days in Marine Corps history. With confidence in our arms. The 36th President of the United States died this afternoon. Tell them there are children and women in here to call it off. The German expedition of stood apart from earlier polar trips. They arrived with clear intentions to secure territory on the Antarctic continent. Their efforts centered on Queen Maud Land, where they conducted extensive surveys and set up presence markers across the region. This happened just one year before World War II began, and it showed Germany had long-term interests in the frozen continent. Beyond the public mapping work, the Germans showed an interest in locations that could support more secretive activities. They searched for areas with natural protection and access points that might work for sustained operations. Some researchers point to evidence that they began construction on a hidden outpost known as Base 211. The purpose reportedly included developing advanced technology away from prying eyes and creating a possible safe location if the situation in Europe deteriorated. These early German moves in Antarctica created a lasting shadow. The combination of territorial claims and rumors of a hidden infrastructure raised eyebrows in intelligence circles for years afterward. The possibility of a remote base designed for advanced research and a potential refuge added another layer to why other nations later took such strong interest in the same areas. The German expedition also changed how major powers viewed Antarctica. Before the late 1930s, much of the continent was seen as a remote scientific curiosity. Germany's territorial claims showed that nations were beginning to look at Antarctica through a strategic lens. If one country could establish a foothold there, others might eventually follow. What had once been a distant frontier was becoming part of a growing competition between world powers. When World War II ended in 1945, the United States started paying closer attention to Antarctica. American intelligence had tracked German activity in the region and they wanted to know what if anything remained from the 1938 expedition. At the same time, new worries appeared on the horizon as the Soviet Union began showing interest in the polar areas. The Americans knew the Germans had poured enormous resource into advanced scientists and engineers. Men like Wernher von Braun had helped build the V-2 rocket, a weapon that struck allied cities from the edge of space and pointed towards the future of warfare. After Germany collapsed, von Braun and many others were brought into American hands through Project Paperclip. Von Braun would later lead America's space program and become one of the key figures behind NASA's Saturn V-5 rocket. Officially, the United States wanted men like him for their expertise in rockets, aircraft, medicine, and military technology. But their recruitment raised the darker question. If America was racing to capture Nazi scientists and weapons, what happened to the men, machines, and research that did not fall into the allied hands? Could some of it have disappeared before the war ended? Moved by U-boat, hidden in remote territory or carried to places the allies had not yet searched? That possibility gave Antarctica a new kind of importance. Germany had already claimed part of the continent, and if even a fraction of its personnel, technology, or records had escaped to the ice, then Operation Highjump may have been more than a training mission. It may have been a search for whatever the Third Reich left behind. These factors, the Soviet moves, and the leftover German capabilities pushed American planners into action. They did not want to leave the southern continent open for others to claim or develop. By 1946, the Navy had decided it was time to mount a major operation of their own. Operation Highjump would give them a chance to investigate the region directly and establish a stronger United States presence before anyone else could move in. The public face of the mission would be Admiral Richard Byrd. Few Americans knew Antarctica better. Byrd had already become famous through multiple polar expeditions and was widely regarded as one of the world's leading explorers. His involvement gave Operation Highjump immediate credibility, but it would also tie his name to the questions and controversies that followed the mission for decades. The Navy laid out several clear goals for Operation Highjump. The first priority involved training personnel and testing equipment in extreme cold conditions. They wanted to see how men, ships, aircraft, vehicles, clothing, and supplies held up in Antarctic weather. This included trying out new items like helicopters in near freezing temperatures where nothing had been tested on this scale before. The Navy needed real data on what worked and what failed when pushed to the limit. A major part of the mission focused on mapping. Planes would fly extensive routes to photograph as much of the continent as possible. The goal was to capture detailed aerial images of coastlines and inland areas that remain largely unknown. These flights aimed to produce thousands of photographs and to create better maps than anything available at the time. The expedition also set out to establish a new base called Little America 4 on the Ross Ice Shelf near the Bay of Whales. This would serve as the main operational hub for the teams on the ice. From there, they planned to test methods for building and maintaining air bases on snow and ice. They wanted to figure out the best ways to construct runways, support aircraft operations, and keep everything running through the harsh conditions. Finally, the mission carried a strategic purpose. The United States wanted to strengthen and extend American claims over parts of Antarctica. By putting boots on the ground, flying the flag, and conducting wide-ranging operations, they aimed to show a presence on the continent. These objectives combined practical military training with exploration and long-term geopolitical interests in the polar south. The size of the force the Navy put together for Operation High Jump really stands out. They assembled Task Force 68 with 13 ships in total. This included the aircraft carrier the USS Philippine Sea, which brought planes and served as a floating command center. They also brought along the icebreaker USS Northwind, several destroyers, submarines, and a fleet of support vessels carrying supplies and fuel for the long journey. In the air, they had 33 aircraft of different types. This included seaplanes, helicopters, and long-range reconnaissance planes. On the ground, in the ice, they had over 4,700 men. That number included sailors, pilots, marines, scientists, and support crews. They brought everything from heavy tractors and weasels for moving across the snow to specially trained dogsled teams. For what the Navy officially called a training and mapping mission, this was an enormous operation. It was one of the largest single expeditions ever sent to Antarctica at this point. The scale went far beyond what most people would expect for simple cold training. The entire operation was strongly backed by James Forrestal, who was the Secretary of the Navy at the time. He later became America's first Secretary of Defense. Forrestal helped authorize or support the mission. Byrd allegedly returned from Antarctica and made alarming comments about future attacks coming from over the poles. Soon after, UFO sightings exploded in 1947. Then Forrestal, one of the few men positioned high enough to know what was really happening inside the new national security state, deteriorated mentally and was hospitalized in Bethesda Naval Hospital. In May of 1949, he died after falling from a 16th floor window. The official ruling was suicide, the death of a man who had broken under pressure of the early Cold War. But to conspiracy theorists, the sequence looked less like coincidence and more like a man who either learned something he could not live with or became part of a story the public was never allowed to fully understand. Another mystery adding to the legend was Hitler himself. The official story said he died in Berlin in April of 1945, but even that account left room for doubt. For decades, the Soviet claimed to possess part of Hitler's skull, only for later testing to reveal it belonged to a woman. Dental remains were used to support the official conclusion that he died in the bunker, but Soviet secrecy, missing evidence, conflicting accounts, and the lack of transparent public proof created a vacuum where the escape theories could survive. If Nazi scientists, officers, and intelligence assets escaped Europe after the war, could Hitler have escaped as well? Some believe he fled by U-boat to Argentina. Others claim the trail led to Antarctica, where rumors of hidden German bases had already taken hold. Could this be why the United States sent such a massive naval task force to Antarctica just one year later? The fleet left the United States in December of 1946 and headed south toward Antarctica. The crossing started with rough seas and strong storms that tested the ships early on. One of the most serious moments came when the submarine, the USS Sennett, got trapped in the thick ice. The crew worked hard to free the boat before it suffered major damage. These early problems created tension among the men as they realized just how unforgiving the environment could be. Once the task force reached Antarctic waters, things got even more difficult. On December 30, 1946, a seaplane called George I crashed during a reconnaissance flight near Thurston Island. Three crew members died in the wreck. The rescue effort turned into a major operation as teams fought brutal weather to reach the survivors. This incident became one of the clearest reminders of the dangers the men faced throughout the mission. During their flights, the crews came across some surprising sights. One of the strangest was an area known as Bunger Hills. They found ice-free lakes and patches of bare ground sitting in the middle of the frozen wasteland. These oases stood out sharply against the endless snow and ice around them. The discovery raised immediate questions about what caused these unusual warm spots in such an extreme environment. Admiral Richard Berg himself led several important flights from the carrier and from the bases on the ice. The teams carried out an intense mapping campaign that produced more than 70,000 aerial photographs. They covered huge sections of the continent that had never been properly documented before. Interestingly, most of those 70,000 photos have been since declassified and are available to researchers and the public today. Yet that openness makes the secrecy around the parts of the mission stand out even more. At the same time, the men dealt with the constant challenges from the environment. Temperatures dropped to the extremes that froze equipment and pushed every piece of gear to its limit. The crews learned quickly how difficult it was to operate aircraft, vehicles, and living quarters in those conditions day after day. The Navy had originally planned for Operation High Jump to run through most of the Antarctic summer. They expected the mission to last six months or longer. Instead, the entire task force pulled out by late February of 1947, only two months in. The official explanation pointed to the approaching winter and the worsening weather conditions that made it too dangerous to stay. The early departure immediately drew the attention because of the scale of the operation. Operation High Jump involved thousands of personnel, dozens of aircraft, and months of planning. Ending the mission ahead of schedule meant that some objectives would go unfinished and raise questions about whether conditions on the ice had proven more difficult than expected. The decision also fueled speculation that factors beyond weather may have influenced the Navy's timetable. Many crews later shared different stories. Some talked about strange radar contacts and aircraft they could not identify. Others mentioned feeling like they were being watched or even pursued in certain areas. These rumors suggested something more aggressive may have played a role in the early departure. The possible link to earlier German activities remains one of the most discussed parts of the stories. Some researchers believe the German expedition left behind more than maps and territorial claims. The Nazis had developed some of the most advanced aircraft technology in the world by the end of the war. This included the Me-262, the first operational jet fighter, along with radical flying wing designs like the Horton HO-229. They were also working on other experimental jets and propulsive systems that were far ahead of anything the Allies had at the time. Theories suggest that some of this advanced technology, along with the scientists who built it, may have moved to Antarctica through escaped U-boats. If even a portion of that capability made it to base 211, it would help explain why the United States sent such a large military force to investigate the region in 1946. After the fleet returned home, Admiral Richard Byrd made some striking comments. In a March 1947 interview with the Chilean newspaper, he warned about the need for strong defenses in the polar regions. He spoke about aircraft that could fly from pole to pole at incredible speeds and describe the future threat that could come from those directions. These statements stood out because they differed from the official success narrative the Navy was putting out. Byrd's words added fuel to the idea that something unusual had taken place during the mission. Back in the United States, the story presented to the public was much simpler. In 1948, the Navy released a film called The Secret Land that showed Operation High Jump as a big success in training and exploration. The film featured Hollywood stars and focused on the positive achievements while leaving out the early withdrawal and any unusual reports. Much of the detailed mission information stayed classified for years. The key difference between the public version and the private concerns has led many to believe key parts of the story were kept quiet. Just a few months after the task force returned, the United States experienced one of the strangest UFO waves in its history. In June of 1947, pilot Kenneth Arnold reported seeing fast-moving objects near Mount Rainier, giving birth to the phrase flying saucer. One month later came Roswell. To most historians, these events belonged to the early Cold War, a time of fear near aircraft, secret weapons, and nuclear paranoia. But to those already suspicious of Operation High Jump, the timing felt impossible to ignore. Whether the theories surrounding Operation High Jump are true or not, the expedition helped shape how Antarctica would be viewed for decades. The continent became the focus of international agreements, scientific missions, and continuing strategic interest for major nations. Antarctica remained isolated from most military activity, but it never disappeared from geopolitical planning. What happened during those months in 1946 helped ensure that one of the most remote places on earth would remain important long after the ships returned home. Even today, large parts of Antarctica remain heavily restricted. Some areas require special approval, and certain zones stay off-limits to most people. Occasional reports continue to surface about unusual activity in restricted research sites. For decades, stories like Operation High Jump were easy to dismiss. Antarctica, Nazis, secret bases, and strange aircraft. It sounded like the kind of thing that belonged in pulp magazines and late-night radio. But then something changed. The United States government itself began saying the quiet part out loud. UFOs were rebranded as UAPs. Congress held hearings. Whistleblowers came forward. The Pentagon created the All-Domain Anonymously Resolution Office, known as ARO, to investigate reports of unidentified anomalous phenomena using a formal government process. Then came the documents. In May of 2026, the Pentagon began releasing new UAP files through the Presidential Unsealing and Reporting System for UAP Encounters, or PURSUE. The first release included records from the FBI, Department of Defense, NASA, and the State Department, with reports stretching back decades. None of that proves aliens were hiding under the Arctic ice. It does not prove Hitler escaped. It does not prove Base 211 existed. But it does prove one thing. The subject is no longer just a joke. The same government that once mocked UFO questions now has offices, hearings, files, and official release systems dedicated to them. And that brings us back to Operation High Jumbo. If strange aircraft were being reported in 1947, if the military was already worried about future threats coming from over the poles, and if today that government admits there are aerial encounters it still cannot fully explain, then maybe the old Antarctic question deserves another look. Not because every theory is true, but because the official story has never been enough to kill the mystery. So, was Operation High Jumbo simply a massive training and mapping mission? Was it a for Nazi technology left behind after the war? Or for the Nazis who may have escaped with it? Or did the U.S. Navy encounter something in Antarctica that helped launch the modern UFO age?
