Time Line of UAVs

Years before the first manned airplane flight on December 17, 1903, primitive UAV technology was used for combat and surveillance in at least two wars.

During World War I, the first UAVs took flight in the U.S. Though the success of UAVs in test flights was erratic, the military recognized their potential in combat. Armistice arrived before the prototype UAVs could be deployed in earnest.

For more than a decade after the end of World War I, development of pilotless aircraft in the U.S. and abroad declined sharply. By the mid-to-late 1930s, new UAVs emerged as an important combat training tool.

During World War II, Nazi Germany's innovative V-1 demonstrated the formidable threat a UAV could pose in combat. America's attempts to eliminate the V-1 laid the groundwork for post-war UAV programs in the U.S.

From their early use as target drones and remotely piloted combat vehicles, UAVs took on a new role during the Vietnam War: stealth surveillance.

The success of the Firebee continued through the end of the Vietnam War. In the 1970s, while other countries began to develop their own advanced UAV systems, the U.S. set its sights on other kinds of UAVs.

During the late 1970s and throughout the 1980s, the Israeli Air Force, an aggressive UAV developer, pioneered several important new UAVs, versions of which were integrated into the UAV fleets of many other countries, including the U.S.

UAVs command a permanent and critical position in high-tech military arsenals today, from the U.S. and Europe to Asia and the Middle East. They also play peaceful roles as monitors of our Earth's environment.

The surveillance UAVs of tomorrow may evolve into MAVs, or micro aerial vehicles, lilliputian spies so tiny they can take off and land in the palm of their operators' hands. The U.S., Great Britain, Korea, and Israel are developing MAVs for surveillance use in the future.
