The Enola Gay, the Silverplate B Twenty-Nine, and the Restoration Fight That Split a Nation Before She Ever Reached the Museum Floor

The Enola Gay, the Boeing B-29 Superfortress that dropped the atomic bomb on Hiroshima, survived one of the longest and most contentious restorations in aviation history. Over roughly 20 years - from 1984 to 2003 - Smithsonian technicians logged more than 300,000 staff hours rebuilding the corroded, partially looted aircraft. The far harder fight, though, was not mechanical: it was a national argument over how the airplane should be displayed, one that cost a museum director his job before she ever stood whole on the museum floor.

Today the fully reassembled aircraft sits at the Steven F. Udvar-Hazy Center near Dulles Airport in Virginia, polished to bare metal. Most visitors walk past without knowing they are looking at one of the most argued-over airplanes in American history - not for what she did in the air, but for what it took to save her.

What Made the Enola Gay a “Silverplate” B-29?

The Enola Gay was not an ordinary Superfortress. She was one of the Silverplate aircraft, the code name for a special run of B-29s modified for the atomic bomb mission. Their bomb bays were reconfigured, and most of the gun turrets were stripped off to save weight. They received fuel-injected engines and reversible propellers - the latest and best equipment Boeing could install.

Only 46 aircraft were built to the Silverplate standard. The Enola Gay rolled out of the Martin plant at Bellevue, Nebraska, in the spring of 1945.

Colonel Paul Tibbets selected her off the assembly line himself. The morning before the mission, he had his mother’s name painted on the nose: Enola Gay. On August 6, 1945, she carried out the atomic bombing of Hiroshima.

How Did the Enola Gay End Up in Pieces?

Fame did not translate into care. After the war, the aircraft flew back to the United States and sat exposed to the weather at Davis-Monthan in Arizona. In 1949, Tibbets flew her to Chicago and formally handed her over to the Smithsonian.

The Smithsonian then faced a practical problem: it had an enormous, historic aircraft with a 141-foot wingspan and nowhere to put her. So she went into outdoor storage at Andrews Field, enduring rain, snow, and years of sun baking the aluminum. Birds and insects got inside. So did souvenir hunters, who pried off instruments, cut pieces of skin, and stole gauges out of the panel.

In 1961, the airplane was finally moved indoors to a storage facility at Suitland, Maryland - a place restoration crews came to call the Silver Hill boneyard. To fit her inside, they disassembled the entire aircraft: wings off, engines off, fuselage in sections. And there she sat, broken into pieces, for decades, slowly corroding.

Who Restored the Enola Gay, and How Long Did It Take?

The effort to save her was set in motion under Paul Garber, the Smithsonian’s curator and the founding spirit of what became the National Air and Space Museum. The storage facility is named for him to this day. But the actual labor fell to the technicians of the restoration shop, who began work in 1984.

When they opened the sections, the damage was worse than feared. Magnesium castings had corroded. Bird droppings and animal nests were packed into the airframe. Rubber components had turned to tar or crumbled to dust, and the self-sealing fuel bladders had rotted. Wiring insulation had gone brittle, and white powdery aluminum corrosion had spread throughout.

The crews disassembled components down to the individual part - every bolt, bracket, and cable. They cleaned each piece by hand, stripped corrosion, and re-plated hardware. When a part was too far gone, they fabricated a new one to the original Boeing drawings and kept the old piece tagged and boxed, because sound restoration preserves history rather than discarding it.

What Was Involved in Rebuilding the Engines?

The aircraft’s four Wright R-3350 Duplex Cyclone engines were a project in themselves. Each was an 18-cylinder, twin-row radial - the same powerful but troublesome engines that plagued wartime B-29 crews with a tendency to catch fire.

Every one of the four engines was torn down to the case and rebuilt - cleaned, inspected, corrosion-treated, and reassembled.

Across the whole aircraft, the crews logged more than 300,000 staff hours of labor stretched across nearly two decades, from 1984 to 2003. That is less a restoration than a life’s work, handed from one craftsman to the next.

Why Was the Enola Gay Exhibit So Controversial?

While technicians worked over corroded castings with dental picks and solvent, a very public fight erupted around the aircraft. In the early 1990s, the Air and Space Museum decided the 50th anniversary of the end of World War II was the moment to put the Enola Gay’s forward fuselage on display, and it planned a full exhibit around her.

That exhibit became one of the most bitter public disputes over history in the country. Veterans groups felt the proposed presentation put the airplane on trial. Historians argued the full weight of what the aircraft did had to be shown. The Air Force Association, members of Congress, and newspaper editorial boards all joined the fray.

The museum’s director eventually resigned, and the large exhibit was cancelled. In 1995, what finally went on display was only the restored forward fuselage in a much simpler presentation. The physical object those craftsmen had labored over was caught in a crossfire that had nothing to do with rivets and everything to do with memory.

Where Is the Enola Gay Displayed Today?

The final chapter came when the museum opened the Steven F. Udvar-Hazy Center near Dulles Airport in December 2003 - a hangar finally large enough to hold the aircraft whole. Crews brought all the sections together, and for the first time since the early 1960s, the Enola Gay was one complete airplane again, reassembled and standing on her own gear.

Visitors can walk the length of the wing - 141 feet, tip to tip - and see the light come off the bare metal. Every square foot of that skin passed through someone’s hands: cleaned, treated, and set back exactly where Boeing installed it roughly 80 years ago.

That is what a museum airplane truly is. Not a trophy and not a verdict, but the actual object, saved, so the conversation about its meaning never has to end. Historians and the public can argue about what the aircraft represents - but someone had to preserve the thing first, or there would be nothing left to argue about.

Key Takeaways

• The Enola Gay is a Silverplate B-29 Superfortress, one of only 46 built to that specification, produced at the Martin plant in Bellevue, Nebraska, in spring 1945.
• After decades of outdoor storage and vandalism, the Smithsonian disassembled the aircraft in 1961 and left it in pieces at the Silver Hill facility in Suitland, Maryland.
• The restoration ran from 1984 to 2003 and consumed more than 300,000 staff hours, including a complete teardown and rebuild of all four Wright R-3350 engines.
• A 1990s dispute over how to exhibit the aircraft for the war’s 50th anniversary led to the museum director’s resignation and cancellation of the planned exhibit; only the forward fuselage went on display in 1995.
• The fully reassembled aircraft has been displayed whole at the Udvar-Hazy Center since December 2003, with a 141-foot wingspan spanning the hangar floor.
