Who built the world first military plane?

The world's first military airplane is widely credited to the Wright brothers, Orville and Wilbur Wright, who developed the Wright Flyer in 1903. However, the first military aircraft specifically designed for combat was the Wright Model B, which was used by the U.S. Army Signal Corps in 1911. This marked the beginning of military aviation, as it paved the way for later developments in military aircraft technology.
