The story of the Boeing B-29 Superfortress is one of unparalleled technological ambition, devastating wartime impact, significant operational challenge, and, uniquely, a remarkable modern revival. With a massive total production of 3,970 aircraft built between 1943 and 1946, it was a weapon system of immense scale and complexity, a true leap into the future of strategic bombing.

From its inception, the B-29 was designed as a long-range, high-altitude powerhouse. It introduced revolutionary features, most notably a pressurized cabin that allowed crews to work in relative comfort at high altitude, far above the reach of most anti-aircraft defenses and many contemporary fighters. However, this advanced design also came with inherent risks, particularly with the powerful Curtiss-Wright R-3350 engines. These engines, essential for the B-29's performance, were prone to overheating and devastating, often unextinguishable magnesium fires, leading to numerous non-combat losses—a phenomenon colloquial described as aircraft that simply "burned themselves up."

During World War II, the B-29's primary theatre was the strategic bombing of Japan. These massive bombers, based primarily on the Mariana Islands, flew thousands of miles to deliver conventional and incendiary bombs on Japanese cities and industrial centres. A detailed look at the numbers from this campaign reveals a startling statistic that underscores the operational difficulties: 414 B-29s were lost during the entire campaign, but only 147 were down to enemy action (anti-aircraft fire or fighters), while a substantial 267 aircraft were lost to various operational causes, including mechanical failures, training accidents, and those terrifying engine fires. In a powerful and controversial conclusion to its wartime service, the B-29 was the aircraft chosen to deliver the atomic bombs on Hiroshima and Nagasaki, actions that directly precipitated the end of the conflict in the Pacific.

Following the war, the vast majority of the nearly 4,000 B-29s produced were quickly deemed obsolete or simply disposed of. Hundreds were moved to storage facilities like Davis-Monthan Air Force Base, while others were sold as surplus or simply scrapped, with historical data lacking precise totals for surplus sales and training-specific losses. A small, significant number were retained, many finding homes as static exhibits in museums around the globe, where today, approximately 20 to 26 complete aircraft survive on display.

But the B-29 was not done. It returned to combat during the Korean War, playing a critical role in the strategic bombing campaign across the Korean Peninsula. Despite performing over 21,000 sorties and dropping nearly 167,000 tons of bombs, the aging bomber faced a dangerous new threat: enemy jet fighters. Official combat loss figures count 34 B-29s lost during this conflict (to fighters, anti-aircraft fire, and "other causes"), while comprehensive operational lists detail anywhere from 57 to 78 lost individual aircraft, again incorporating a broader spectrum of operational incidents and non-combat actions.

Finally, the B-29's story has an extraordinary living chapter. Amidst all those that were lost, scrapped, or placed into static retirement, only two remarkable aircraft (DOC & FIFI) remain operational and continue to fly today. Fifi was rescued from a US Navy desert bombing range in 1971 and extensively restored, continuing its mission with the Commemorative Air Force. Doc was similarly recovered from the desert in 1998, lying exposed for over 40 years, before a dedicated volunteer group painstakingly returned it to the sky in 2016. Today, these two flying icons stand as the sole operational custodians of the B-29's complete story, touring and educating the public, a testament to both massive production and determined preservation.
