On a crisp morning in 1951, the silhouette of a groundbreaking aircraft graced the skies as the Boeing B-47 Stratojet claimed its place in the annals of aviation history. The B-47 was not merely a testament to post-World War II innovation but also a cornerstone of the United States Air Force’s Strategic Air Command during the height of the Cold War.

The Stratojet was the first multi-engine, swept-wing jet bomber of its kind. With its six-engine configuration and sleek design, the B-47 shattered existing paradigms of bomber technology. Its swept wings, spanning 116 feet, were designed to enable high subsonic speeds and to facilitate high-altitude flying, which allowed it to evade enemy interception efforts with relative ease.

But the B-47’s contributions were not limited to its impressive engineering. It played an instrumental role in strategic reconnaissance over the Soviet Union, gathering invaluable intelligence that shaped U.S. military strategy during the Cold War era. In particular, the RB-47 reconnaissance variant was central to this effort, performing some of the most sensitive missions of the time.

Following its first flight on July 3, 1953, the RB-47E conducted some of the most sensitive reconnaissance missions of the Cold War. At least two of these aircraft were lost while flying missions over the Soviet Union. One such incident involved an RB-47E during a photographic mission over Soviet airspace. The plane was intercepted and fired upon by Soviet MiGs, resulting in wing damage. Fortunately, it managed to outpace the MiGs at high altitude and safely return to its base in the United Kingdom. However, on July 1, 1960, an RB-47H flying over the Barentz Sea was shot down by Vasili Poliakov. While the navigator John McKone and co-pilot Bruce Olmstead survived, the pilot Bill Palm and the other three crew members, who were ELINT operators, lost their lives.

Operating as a significant element of SAC’s strength throughout the 1950s and into the early 1960s, the B-47 remained in service as a bomber until 1965. Its adaptability for various missions, including photo reconnaissance, electronic intelligence, and weather reconnaissance, kept it operational in these roles until 1969, and as a test bed until as late as 1977.

As the B-47 phased out of active service, it was succeeded by more advanced reconnaissance aircraft such as the U-2 and SR-71 spy planes. Nevertheless, the legacy of the Stratojet is indelible; it set the precedent for modern jet airliners and inspired a range of aircraft designs, from tankers to the Boeing 707 series, which catalyzed Boeing’s rise as an industrial titan.

Reflecting on the B-47’s enduring relevance, Jim Walther, Museum Director, stated, “It was a mainstay of the United States Air Force’s Strategic Air Command’s strength during the 1950s and early 1960s.” This sentiment is echoed by aviation enthusiasts and historians who recognize the Stratojet as a crucial chapter in both military and aviation history.

In honor of this iconic aircraft, the National Museum of Nuclear Science & History has undertaken “Operation Preservation,” a multi-year campaign to repaint and refurbish a B-47E, serial number 53-2280, one of only 23 remaining B-47 aircraft. This project underscores the significance of preserving such historic artifacts that reflect the technological leaps and strategic foresight of a pivotal era in global military dynamics.
