How atomic bombs were prepared for Hiroshima and Nagasaki

The U.S. National Archives and Records Directorate has completely removed the "top secret" stamp from the RG-77-BT photo collection stored at the National Archives branch in College Park, Maryland.

Thus, dozens of unique photographs taken during the preparation for the atomic bombing of Japanese cities, which took place in the spring and summer of 1945 on the island of Tinian in the Pacific Ocean, became available.

Before that, you could see only models of two atomic bombs (they were declassified in 1960), the infamous B-29 bomber (Enola Gay), which dropped the bomb on Hiroshima and some photos from the now declassified RG-77-BT collection.

This is not a museum model in the picture, but the Little Boy atomic bomb, which sent 80,000 people to fiery hell and then killed about 120,000 more Hiroshima in the next five years. It is placed on the test bench during the verification of the operation of automatic systems.

02. And this is the Fat Man (Fat Man) atomic bomb, already assembled and ready to use, that destroyed Nagasaki. Its seams are carefully puttyed with sealant and painted to maintain the stable operation of internal systems of the structure.

10. Two special pits were made to load bombs into the bombers. Now they are covered with glass caps and turned into museum exhibits.

28. What happened next, you know. On August 6, at 1:45, a B-29 bomber under the command of the commander of the 509th mixed aviation regiment, Colonel Paul Tibbets, carrying the Kid’s atomic bomb, took off from Tinian Island, about 6 hours from Hiroshima. Tibbets's plane flew as part of a compound that included six other aircraft: a backup aircraft (Top Secret), two controllers and three reconnaissance aircraft (Dzhebit III, Full House and Street Flash). Scout commanders sent to Nagasaki and Kokura reported significant cloud cover over these cities. The pilot of the third reconnaissance aircraft, Major Iserli, found out that the sky above Hiroshima was clear and sent the signal "Bomb the first target." At 08:15 local time, the B-29, at an altitude of over 9 km, dropped an atomic bomb on the center of Hiroshima. The fuse was mounted 600 meters above the surface; The explosion, equivalent to 13 to 18 kilotons of TNT, occurred 45 seconds after the dump.

At 2:47 a.m. on August 9, an American B-29 bomber under the command of Major Charles Sweeney, carrying the Fat Man atomic bomb on board, took off from Tinian Island. Cloudiness over the city of Kokura did not allow for targeted bombing, and after three unsuccessful approaches to the target, at 10:32 a.m. B-29 headed for Nagasaki. The “fat man” was dumped almost blindly, in addition, the aircraft had technical problems with the fuel pump and there was not enough fuel for an additional approach. The explosion occurred at 11:02 local time at an altitude of about 500 meters. The power of the explosion was about 21 kilotons.

The architect of the Exhibition Center of the Hiroshima Chamber of Commerce and Industry, who now knows the whole world under the name "Atomic Dome", was the trade attache of Czechoslovakia, Jan Letzel (pictured). He lived for several years in Japan, where he designed several buildings in an unusual European style for the Japanese. In addition, Letzel helped Czechoslovak legionnaires returning from Vladivostok, providing them with the opportunity to return to Europe by ship. The building of the Exhibition Center was 160 meters from the epicenter of the atomic bomb explosion and one of the few to resist, now becoming one of the main anti-war symbols in the world.

PS This year marks the 70th anniversary of the atomic bombing of Japanese cities. The inhabitants of Hiroshima and Nagasaki were the first and, fortunately, the last victims of the use of nuclear weapons on Earth. Since then, much has changed, the world has experienced a monstrous nuclear arms race, was on the verge of a new conflict, but was able to get out of this madness. Unfortunately, now the new hawks have begun to promote the theme of global war. The world is again threatened with nuclear weapons not only by the crazy Russian "patriots" who have fled from the coils from the militaristic intoxication, but also by the top leadership of Russia. All this causes the most serious concerns for the future of Europe and the whole world.
