Trinity Jumbo Device









The Jumbo device was intended to contain the precious core of the first implosion device, the Trinity shot, in the event of a fizzle.

"As delivered in May 1945, Jumbo was 10 feet (3.0 m) in diameter and 25 feet (7.6 m) long with walls 14 inches (360 mm) thick, and weighed 214 long tons (217 t). A special train brought it from Barberton, Ohio, to the siding at Pope, where it was loaded on a large trailer and towed 25 miles (40 km) across the desert by tractors. At the time, it was the heaviest item ever shipped by rail."
