Initially used for reconnaissance, aircraft quickly evolved into weapons. Early "dogfights" involved pilots with pistols before machine guns were synchronized to fire through propeller blades. Iconic models included the Sopwith Camel and the Fokker D.VII .

Modern warplanes are highly specialized or increasingly "multirole," capable of performing several missions in one flight.

This era saw all-metal monoplanes like the P-51 Mustang and Spitfire . It also introduced jet propulsion with the Messerschmitt Me 262.

Innovations moved rapidly from the first supersonic flights to the integration of radar and missiles. The Harrier Jump Jet introduced vertical take-off and landing (VTOL).

Since the Wright brothers' first flight, military aviation has progressed through several distinct technological eras.

In the 1980s, technology shifted toward radar invisibility. The F-117 Nighthawk and B-2 Spirit revolutionized deep-strike capabilities. Modern Categories and Roles
