Information, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Boeing B-29 Superfortress "Enola Gay":
Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of Planet War II and the 1st bomber to property its crew in pressurized compartments. Despite the fact that developed to fight in the European theater, the B-29 identified its niche on the other side of the globe. In the Pacific, B-29s delivered a assortment of aerial weapons: traditional bombs, incendiary bombs, mines, and two nuclear weapons.
On August six, 1945, this Martin-constructed B-29-45-MO dropped the 1st atomic weapon employed in combat on Hiroshima, Japan. Three days later, Bockscar (on show at the U.S. Air Force Museum close to Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Excellent Artiste, flew as an observation aircraft on both missions.

Information, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Grumman F6F-3 Hellcat:
The Grumman F6F Hellcat was initially conceived as an sophisticated version of the U.S. Navy’s then existing front-line fighter, the F4F Wildcat (see NASM collection). The Wildcat’s intended replacement, the Vought F4U Corsair (see NASM collection), 1st flown in 1940, was showing wonderful promise, but development was slowed by troubles, including the crash of the prototype.
The National Air and Space Museum’s F6F-three Hellcat, BuNo. 41834, was built at Grumman’s Bethpage, New York, factory in February 1944 below contract NOA-(S)846. It was delivered to the Navy on February 7, and arrived in San Diego, California, on the 18th. It was assigned to Fighter Squadron 15 (VF-15) on USS Hornet (CV12) bound for Hawaii. On arrival, it was assigned to VF-three where it sustained harm in a wheels-up landing at NAS Barbers Point, Hawaii. Following repair, it was assigned to VF-83 where it was utilised in a instruction function till February 21, 1945. After numerous transfers 41834 was converted to an F6F-3K target drone with the installation of sophisticated radio-manage gear. It was painted red with a pink tail that carried the number 14. Its mission was to be employed in Operation Crossroads – the atomic bomb tests at Bikini Atoll. It flew on June 24, 1946, with a pilot, on a practice flight and was launched, unmanned, quickly after the 1st bomb test. Instrumentation on board and photographic plates taped to the handle stick obtained information on radioactivity. Three much more manned flights preceded the final unmanned flight on July 25, 1946, which evaluated the very first underwater explosion. Records indicate that exposure of this aircraft to the radioactive cloud was minimal and residual radiation is negligible.
F6F-3K 41834 was transferred to NAS Norfolk and logged its final flight on March 25, 1947, with a total of 430.2 flying hours. It was assigned to the National Air Museum on November three, 1948, and remained at Norfolk until October 4, 1960, when it was moved by barge to Washington and placed in storage. In 1976 this Hellcat was loaned to the USS Yorktown Museum at Charleston, South Carolina. A superficial restoration was performed at the museum, but because of the harsh environment and its poor condition the Hellcat was returned to NASM on March 16, 1982. In 1983, it was sent to Grumman Aerospace where a group of volunteers entirely restored the aircraft. In 1985, it was shipped back to the Paul E. Garber Preservation, Restoration and Storage Facility in Suitland, Maryland, and put in storage. NASM’s F6F-3 Hellcat is scheduled to be displayed in the new Steven F. Udvar-Hazy center at Dulles International Airport in Virginia in 2004.
