Costing USD 3 billion, the Boeing B-29 Superfortress is history's most notorious aircraft. Featuring pressurised cabins and remote-controlled guns, it executed the deadliest conventional air raid in Tokyo and the only nuclear strikes in warfare.

‘Pressurised and lethal’: How the B-29 bomber unleashed unprecedented destruction in 1945

To drop the atomic bomb on Hiroshima, the US military heavily modified the B-29 'Enola Gay' under Project Silverplate. Engineers stripped its armour, upgraded the bomb bay, and created a dedicated station to manually arm the weapon mid-flight.


‘Stripped and modified’: Why the US military removed the weapons from its Hiroshima nuclear bomber

On August 6, 1945, the modified USD 3 billion B-29 Superfortress 'Enola Gay' dropped the 'Little Boy' atomic bomb on Hiroshima. The aircraft released the weapon from 31,000 feet, instantly changing the course of global military history.


‘$3 Billion Bomber?’: What was the cost of the US aircraft that decimated a Japanese city

On August 6, 1945, the United States deployed a highly modified Boeing B-29 Superfortress to drop the first atomic weapon used in warfare. This unprecedented mission instantly altered global geopolitics and demonstrated a terrifying new threshold of military power.
