Footage of high explosive tests before Trinity and atomic weapons development

#guerra e crimini di guerra#filmato d'archivio#usa

Archival footage documenting pre-Trinity calibration tests with high explosives, technical blast diagrams, the Little Boy device of August 6, 1945, and naval fleet maneuvers at sea.

The footage documents high explosive tests conducted in advance of Trinity to calibrate measuring instruments and practice procedures. The sequence records a wooden tower structure erected in a desert area with ground personnel and a parked vehicle, wooden crates stacked with the warning label “HIGH EXPLOSIVES DANGEROUS THIS SIDE UP”, three technicians in work coats inside a laboratory with instrument panels, and a concentric diagram outlining blast thresholds from 100 TONS OF TNT and a 65-foot crater diameter to broken glass damage at 100,000. Additional scenes show military personnel in combat gear, a dark bomb casing on a loading lift beneath an aircraft bay, the rising mushroom cloud identified on screen as “LITTLE BOY AUGUST 6, 1945 8:15AM (15 KILOTONS)”, an aerial view of an incandescent fireball, and naval warships cruising in formation in open waters.

Running 8 minutes, this document is hosted on Wikimedia Commons under the title Trinity And Beyond The Atomic Bomb Movie and is dedicated to the public domain. It was directed by Peter Kuran, incorporating sourced United States federal footage produced by the Atomic Energy Commission and the United States Department of Energy (USDE).

Official context is provided by historical documentation preserved in the National Archives and Records Administration (NARA), including Record Groups RG019, RG077, RG181, RG227, and RG298 concerning early United States Navy atomic energy research between 1939 and 1946, alongside RG048, RG075, and RG094 covering early nuclear propulsion studies conducted by Ross Gunn at the Naval Research Laboratory.

This film remains a critical visual record of the developmental transition from preliminary hundred-ton conventional calibration explosions to the deployment of operational atomic weapons and associated naval fleet movements, providing direct visual confirmation of experimental testing protocols and measured damage thresholds.
