The Birth of UAVs: How Drones Were Invented

You might be surprised to learn that the concept of UAVs, or drones, isn't as modern as it seems. It actually dates back to the mid-19th century when Austria experimented with incendiary balloons in warfare.
Fast forward to the 1930s, and you'll find significant strides made by Reginald Denny and the US Navy with radio-controlled aircraft. These early innovations set the stage for future advancements in unmanned aircraft.
But how did we go from rudimentary balloons to the sophisticated drones of today? The answer lies in a series of pivotal developments during key historical moments, including advances in radio technology, miniaturization of components, and improvements in navigation systems.
Early Military Experiments

Military experimentation with unmanned aerial vehicles (UAVs) began as early as July 1849 when Austria launched incendiary balloons to attack Venice. This marked the initial offensive use of air power, setting the stage for future developments in drone technology.
By the 1930s, significant advancements had been made in purpose-built drones. Reginald Denny, an actor and aviation enthusiast, played a pivotal role during this period by collaborating with the US Navy on radio-controlled aircraft. In 1937, the US Navy's Curtiss N2C-2 drone showcased early advancements in radio-controlled UAV technology, including the potential for torpedo delivery.
Simultaneously, the Royal Navy was conducting tests on the Larynx cruise missile during the interwar period. This missile was an early example of offensive UAV technology and contributed to the evolving understanding of aerial warfare.
A notable milestone was the introduction of television guidance by Hungarian scientist Dénes Mihály, which provided real-time visual feedback, enhancing the accuracy of drones. These early military experiments laid the groundwork for the sophisticated UAVs we see today, combining offensive capabilities with advanced guidance systems.
The First Quadcopters
Early quadcopters faced significant design challenges, particularly in terms of stability and control. However, technological advancements in the early 1900s, such as those demonstrated by Bartolomeo Ristori's flying machine, showed the potential of multi-rotor aircraft.

World War II Innovations

During World War II, drone technology made significant strides, altering military strategy permanently. The emergence of military drones like the Radioplane OQ-2 and the Radioplane OQ-3 played a pivotal role in advancing drone combat capabilities. Reginald Denny, a key figure in this evolution, developed the RP-1 drone and demonstrated it to the US Army in 1935, laying the groundwork for future innovations.
The Curtiss N2C-2, a radio-controlled aircraft, showcased early advancements in drone technology. Edward M. Sorensen's patent for radio-controlled aircraft significantly contributed to these developments. By 1945, the US Navy was using such drones, with notable examples like the OQ-2 being utilized, marking early instances of drone combat.
Three key innovations from World War II include:
- Radioplane OQ-2: Mass-produced for training anti-aircraft gunners.
- RP-1 Drone: Reginald Denny's creation that sparked military interest in drones.
- Curtiss N2C-2: One of the initial radio-controlled aircraft used by the US Navy.
These advancements set the stage for the sophisticated drones we see today, proving that World War II was a critical period for drone technology.
