For the first time, explosion of the Atomic Bomb containing plutonium as Nagasaki Atomic Bomb at July 16,1945 in human history

　The first atomic bomb was blasted at 5:29 am on July 16, 1945 at the Alamogordo in New Mexico state in the human history. This experiment was confidentially developed and preliminarily prepared at the Los Alamos National Laboratory in same state. In the cabin surrounded by a tin plate, an atomic bomb containing 36 kg plutonium inserted into 5 tons of metal balls for experimental explosion was strictly installed. Since plutonium is a difficult atom to raise the purity, it had been purified in a huge cyclotron facility in Hanford, Washington state. It was designed to be a sphere for implosion which equally compresses on the surface of pure plutonium usually with an explosion with TNT. Plutonium type with "Fat Man" was dropped and exploded at Nagasaki City.

After a mushroom with enlarging by Nagasaki atomic bomb, a rescue team was dipached from Omura Navy Hospital

   The Omura Navy Hospital, which was about 20km from Nagasaki City, which had been established in October 1942 for the Omura Navy Air Corps. The Omura airfield was closed on May 14, 1945 after catastrophic air raids by US Air Force. 

  The photograph of a mushroom cloud by the Nagasaki atomic bomb was taken from Omura Naval Hospital on August 9. Mushroom clouds moved with enlarging and closer, and the deep red flames burned in the middle of the mushroom cloud accompanied by great lights and sounds. The Mushroom cloud crushed Nagasaki City which had been a port town. At the same time, three umbrellas were  also discovered. The distance from Omura Naval Hospital to the Nagasaki City cloud was 4572 m. Finally after 3 PM on August 9, Omura Navy Hospital send a rescue team by a emergent phone call.

Nagasaki atomic bomb by USA and invasion of Manchuria by the Soviet Union were synchronized on 9th August, 1945

　Imperial Headquarters announced Soviet cross-border attacks on 9th August 1945. East and west Manchuria was invaded with conflict war for defense. North Manchuria and North Korea, were bombed. Asahi News Paper in Japanese announced it at 10th August on the first page for the first time. On 8th August, the Soviet Union declared war on war against Japan from Foreign Minister Morotov. The Soviet Union reported on 9 August that the Soviet Union crossed the Manzhouli and Kotou. 

  Asahi News Paper was posted the Nagasaki Atomic Bomb on 9th August 9, 1945 by the Western Army District Headquarters on 10th August at a following day. It reported that Nagasaki City would be bombed by a new bomb, from of two large aircrafts, and suffered from little damage. At 11 AM on 9th August 9, two large aircraft invaded over Nagasaki City. Shelter form even one plane and exposure of the skin was a great prohibition. They always covered the pit and the edema at the shirt.

  The Vatican blamed the new bomb for Hiroshima on 6th August, in Lisbon on 7th August as an inhumane destructive weapon.

The sudden change in dropping Atomic Bomb to Nagasaki Cily from Kokura City on 9 August, 1945

   The B-29 "Box Car" equipped with "Fat Man" which was exchanged to the Nagasaki Atomic bomb. Kokura city was selected as the second target after the Hiroshima City of the first target to the Atomic Bomb. From the following aerial photograph of June 18, 1945, the hypocenter was set as the armory at Kokura City. The Armory was a military facility, which stored the manufacturing, designing and repairing weapons and ammunition etc. On 9 August, 1945, "the Box Car" took off from Tinian Island and reached the sky above Kokura city at 9:44 AM. At the previous day on August 8, Yawata City in the south 7 km form Kokura  City had suffered severely the air rads. Kokura City was covered with fog and smoke, and it became difficult to visually dispatch "Fat Man" The captain of "Box Car" suddenly changed the second target to Nagasaki City where was the third destination at 10:30, because the residual fuel continued to be exhausted. Temporarily it was possible to visually drop from the clouds, and "Box Car" dropped Fat Man to explode at 11:02. Nagasaki City. The hypocenter had deviated to the Urakami district in the northwest by about 3 km.

The captain for Nagasaki Atomic Bomb smiled and greeted the captain of Hiroshima Atomic Bomb

The B - 29 bomber called "Box Car" dropped a plutonium type of atomic bomb called "Fat Man" to Nagasaki City and burst at 11:02 am on August 9, 1945. Captain Charles W. Sweenney, who was piloting "Box Car", will return to Tinian Island at the same evening. He received bless from Paul Warfield Tibbets, Jr who piloted Enola Gay and dropped a uranium type of atomic bomb called "Little Boy" to Hiroshima City. Sir. Sweeney on the left and Tibet on the right are shaking hands with a smile playing. Afterwards They received army medals and were promoted with promotion as hero. They legitimized the dropping of atomic bombs for the end of the war in all their lives.

Scribbling by developers and soldiers at the tail and top of the Nagasaki Atomic Bomb called "Fat Man"

In the process of developing and manufacturing Nagasaki Atomic Bomb called  "Fat Man", many developers' names and scribbling descriptions below were photographed on June 26, 1945 on its tail unit. "Jone Kroes, Dwine Wisoonsin From NY H Wein, HP Lemay Phom 1 / c USN LT. (N) Tomlison USN LT (n) Jecy JE Millward PHOM 3 / c USN, A Schmidt lot of Part. Heres to you! Art Josephs Chicago, D. Jtoco, Dr Salatin, Koester "(UCN: United State Navy, abbreviation for the US Navy). In addition, military shapers described their names and messages on the top unit of the Fat Man for Nagasaki City. They prided their honorable hero out of vanity to drop the atomic bomb. The photographies of this writing on outer coats was confidential and hided as top secret information.

Nagasaki Atomic Bomb expanded the mainstream of atomic bomb and nuclear electric power

   The continuous photographs were captured immediately after the plutonium type atomic bomb exploded on 11:02 am on 9 August 1945 while the Nagasaki Atomic Bomb was dropped. Nuclear fission was a process in which unstable nuclei of plutonium (Pu) collapse are split to generate lighter elements. Just after explosive surrounding the atomic bomb ruptures, the center of plutonium is compressed at once, absorbing the neutrons released and chain reaction of nuclear fission at a stroke. The power of the nuclear fission corresponded to 22,000 tons as a TNT bomb. Repeated fission within the atmosphere and the ability to terminal destruction was estimated to be 35% for heat rays, 50% for blasts and 15% for radioactivity. Nuclear fission of Nagasaki Atomic Bomb remained 5 tons of Plutonium that the contaminated radioactivity was generated and sprayed into Nagasaki City. Spherical Fat-Man type with 32 tetrahedral lens which caused explosive waves to make the early explosion coincide with the arrival point of slow explosion. The coincidence strongly compress the central part of Plutonium was First developed and produce for the first time in the world. The most difficulty ,time and money was took during the Manhattan project. Atomic Bomb and nuclear electric power generation by Plutonium type were expanded into the mainstream in the world  at the most.

Preparation for Nagasaki Atomic Bomb by bombing experiment for Pumpkin type

   At Wendover Air Force Base, "Fat Man" type for endogenous test bombs had been produced. It was a Pumpkin type on 454kg with TNT. For the experiment of the simulated atomic bomb, USA Air Force exploded it by dropping indiscriminately on Osaka City on July 26, Shimada City on July 26th, Haya City on July 29 and so on. After that, "Fat Man" type was experimented using the test bullet F13 on Tinian airport on August 1, 1945. USA Air Force confirmed the function and operation of the test bomb. Further refurbished test bullet F18 was experimented and loaded on B - 29 on August 5, and carried out a dropping test. Until August 9, the F - 31, which was become the Nagasaki Atomic Bomb on August 9, the final experiment entered the completion phase on August 8.

Color image of fireball at the moment Nagasaki atomic bomb exploded

This aerial photograph was one of the first color films by the movies at the moment just after Nagasaki Atomic Bomb exploded from the hypocenter in Nagasaki City. The Plutonium Atomic Bomb called "Fat Man", just after the rupture, the center of the heat-ball reached up to several million degrees at extremely super-high temperature. Nagasaki Atomic Bomb instantly bulged a fireball with a diameter of about 280 m and a surface temperature of about 5000 degrees. It had been storming out the intense hot windstorm and violent radiation into Nagasaki city. It formed a mushroom cloud covering Nagasaki City entirely.

The Mushroom cloud was photographed at the earliest from the ground by Nagasaki Atomic Bomb

It was a mushroom cloud which was taken a photograph at 11:17AM about 15 minutes after 11:02 AM on 9 August 1945 when the Nagasaki atomic bomb exploded. The photo was first taken from the Kawanami shipyard in Koyagi remote island which was about 10 km south-southwest from the hypocenter. The Mushroom clouds taken from the ground in the atomic bomb had been shot at the earliest. "Boxes Cars" dropping the Nagasaki Atomic Bomb was retreating toward the sky above Koyagi island. The isolated island of Koyagi was included Nagasaki Peninsula in the landfill of the 1960s.
