Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress "Enola Gay":
Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of Planet War II and the initial bomber to residence its crew in pressurized compartments. Even though created to fight in the European theater, the B-29 discovered its niche on the other side of the globe. In the Pacific, B-29s delivered a selection of aerial weapons: conventional bombs, incendiary bombs, mines, and two nuclear weapons.
On August six, 1945, this Martin-constructed B-29-45-MO dropped the 1st atomic weapon utilised 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 climate reconnaissance aircraft that day. A third B-29, The Excellent Artiste, flew as an observation aircraft on both missions.

Quoting Smithsonian National Air and Space Museum | Hawker Hurricane Mk. IIC:
Hawker Chief Designer Sydney Camm’s Hurricane ranks with the most critical aircraft designs in military aviation history. Developed in the late 1930s, when monoplanes had been considered unstable and as well radical to be productive, the Hurricane was the very first British monoplane fighter and the 1st British fighter to exceed 483 kilometers (300 miles) per hour in level flight. Hurricane pilots fought the Luftwaffe and helped win the Battle of Britain in the summer season of 1940.
This Mark IIC was constructed at the Langley factory, close to what is now Heathrow Airport, early in 1944. It served as a training aircraft during the Globe War II in the Royal Air Force’s 41 OTU.

Quoting Smithsonian National Air and Space Museum | Northrop P-61C Black Widow:
The P-61 Black Widow was the 1st U.S. aircraft made to find and destroy enemy aircraft at evening and in undesirable weather, a feat produced possible by the use of on-board radar. The prototype 1st flew in 1942. P-61 combat operations started just after D-Day, June six, 1944, when Black Widows flew deep into German airspace, bombing and strafing trains and road targeted traffic. Operations in the Pacific started at about the exact same time. By the finish of Globe War II, Black Widows had noticed combat in each and every theater and had destroyed 127 enemy aircraft and 18 German V-1 buzz bombs.
The Museum’s Black Widow, a P-61C-1-NO, was delivered to the Army Air Forces in July 1945. It participated in cold-climate tests, higher-altitude drop tests, and in the National Thunderstorm Project, for which the prime turret was removed to make area for thunderstorm monitoring gear.
