19. The WWII Bomber That Cost More Than the Atomic Bomb

The Boeing B-29 Super Fortress is best known as the plane that dropped the atomic bombs on Hiroshima and Nagasaki. A leap ahead in aircraft and bomber development, it featured innovations such as a pressurized cabin and machine gun turrets that could be fired by remote control.

Not only was the B-29 the most technologically advanced and revolutionary bomber of WWII, it was also the most expensive military project of the conflict. Bar none. The price tag for the Super Fortress was actually higher than that of the Manhattan Project, which produced the atomic bomb.
