The concept of unmanned aircraft for military purposes has been around for centuries. One of the earliest recorded attempts at such technology dates back to 1849 when Austria launched 200 incendiary balloons toward Venice. However, this attack largely failed as shifting winds blew most of the balloons off course.

The early 20th century, following the Wright Brothers’ historic first flight in 1903, marked the beginning of a rapid push toward developing unmanned aircraft. By the 1940s, the U.S. military had experimented with this technology for over two decades. When the military first unveiled its experimental models of “robot planes” to the public, it did so fittingly at Wright Field in Ohio.

The milestone event was featured in the October 15, 1945, issue of LIFE magazine, accompanied by photographs from Sam Shere. The article described how these early drones operated and the potential they held for the future.

How the First “Robot Planes” Worked

Unlike today’s highly sophisticated drones, the early models of unmanned aircraft were controlled by an operator on the ground or by a pilot in a nearby plane. The remote-control operator used a radio control box, manipulating a pencil-like stick to send signals via a frequency-modulated wave to a receiver inside the aircraft.

These signals activated a component known as the Servo unit—nicknamed “the muscle”—which converted electrical impulses into mechanical movements, steering the aircraft. At the time, these robot planes had a limited range and required an operator to be within four miles. While this may seem restrictive by modern standards, it was a crucial step toward today’s military drones, which can travel hundreds of miles and execute missions with remarkable precision.

The experimental planes featured in LIFE laid the groundwork for what would become an integral part of modern warfare. Today, the U.S. Department of Defense boasts a fleet of more than 11,000 military drones for reconnaissance, surveillance, and combat missions worldwide. The technological advancements from the 1940s to today’s sophisticated autonomous drones highlight the evolution of unmanned aerial systems.

Interestingly, the LIFE article also speculated about future civilian applications for radio-controlled aircraft. The piece suggested that “radio-controlled, wireless airliners” might someday become a reality. While human pilots remain essential to commercial air travel, modern aviation heavily relies on automated systems and computer-assisted navigation, proving that early predictions were not far from the mark.

The unveiling of the U.S. military’s first drones at Wright Field was a defining moment in aviation history. What started as rudimentary remote-controlled aircraft has now evolved into sophisticated, AI-powered drones with extensive military and civilian applications.

Looking back at the origins of unmanned flight, it is clear that these early innovations set the stage for a technological revolution that continues to shape military strategy and air travel today.
