The National WWI Museum's newest exhibit, "Turning Point: The Doolittle Raid, Battle of the Coral Sea, and Battle of Midway," opens April 18, 2012 and will be on display until July 8, 2012.

On July 16, 1945, the world’s first atomic bomb detonated in the New Mexican desert, releasing a level of destructive power unknown in the existence of humanity. Emitting as much energy as 21,000 tons of TNT and creating a fireball that measured roughly 2,000 feet in diameter, the first successful test of an atomic bomb, known as the Trinity Test, forever changed the history of the world.

As the "Hinge of Fate" was turning across the globe, Operation Torch became the US military's first step toward defeat of Nazi Germany in Europe.

The  traveling exhibit tells the story of how World War II became the major catalyst in the 20th century for African Americans seeking change in their fortunes, both on the Home Front and in the American military.
