The history of rockets started right after the development of gunpowder in China, and lacked accuracy and control for centuries, leaving them to be used for panicking men and horses, and later wide-area attack. With the invention of spin-stabilizing, they finally became useful to the military. In the 20th century, sellf-guidance controls were added by the Nazis in their V-2 Rockets, attacking from a distance, In later decades, Infra Red, Radar, and other guidance methods allowed for them to be useful for air-to-air combat and surface-to-surface rockets.
