World War II Service and Diary of John R. McKnight - Ex Rd M 3c USN
By the end of July the Manhattan Project had placed a nuclear weapon at President Truman's disposal. Faced with the possibility of quickly ending the war, the President approved the use of the atomic bomb against Japan. As the first target was chosen, the city of Hiroshima in southern Honshu, Japanese officials were warned of the unprecedented destructive potential.

On August 6 the U.S.S. Essex was about 320 miles south of Kyushu and no missions were scheduled. B 29 Superfortresses had been regularly flying the route north from the island of Tinian to bomb Japan, but Jack and the crew of the Essex had no idea that today one B 29 carried an atomic bomb. At 8:15 a.m. the B 29 "Enola Gay" dropped an atomic bomb on Hiroshima.

Japan refused to surrender and the United States had plans for at least seven more atomic bomb targets. The second was scheduled for August 9 on Kokura, a city on the northern coast of Kyushu. Once again a B 29 left Tinian with an atomic bomb payload. The Superfortress "Bockscar" reached Kokura but clouds covered the target. The mission was diverted to the secondary target, Nagasaki, in east central Kyushu. At 11:01 a.m. the B 29 "Bockscar" dropped the second atomic bomb on Japan. Aircraft from the Essex made routine bombing missions on Honshu.

The massive destruction from the two bombs was enough to bring Japan to its knees. The long awaited end of the war was in sight. On August 15 Emperor Hirohito announced Japan's unconditional surrender.
The Essex continued flight operations of patrolling and reconnaissance while Allied troops began landing on Japanese soil. The U.S.S. Missouri would sail into Tokyo Bay for the formal surrender.

For the crew of the Essex changes were happening fast. On August 29 and 30 personnel from ships of T.G. 38.4 came aboard for transport to the U.S. CV 9 had logged so much time at sea, it would be one of the first to head home for the States.

The B 29 Superfortress "Enola Gay" is currently on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center just outside of Washington D.C.

The B 29 Superfortress "Bockscar is currently on display at the National Museum of the United States Air Force, Wright Patterson Air Force Base near Dayton, Ohio.
