'31,000 feet above Hiroshima': This US aircraft was used to drop the atomic bomb in 1945

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.

Standard B-29s could not carry the massive atomic weapons. Under the highly classified 'Project Silverplate', engineers stripped the bomber of its heavy armour and gun turrets to accommodate the 9,700-pound nuclear payload.

At exactly 8:15 AM on August 6, 1945, the Enola Gay released the bomb from an altitude of 31,000 feet. It took 43 seconds for the weapon to fall before detonating roughly 1,900 feet above the Shima Surgical Clinic.
