Tesla's Teleautomaton (1898)
Nikola Tesla's radio-controlled boat, demonstrated at an electrical exhibition in New York, is widely considered the first remotely piloted vehicle. Tesla envisioned the technology as a way to build unmanned weapons that would make wars so destructive they would become obsolete. The U.S. military was not interested at the time. It took another two decades before the concept moved into the air.
The Kettering Bug and WWI Aerial Torpedoes
In 1918, Charles Kettering developed the "Bug" for the U.S. Army Signal Corps. It was an unmanned biplane designed to fly a preset course and then crash into a target. The Kettering Bug could carry 180 pounds of explosives at a speed of 120 mph, using a simple mechanical system that counted propeller rotations to determine when to cut the engine and dive. The war ended before the Bug saw combat, but it proved the concept of an autonomous aerial weapon.
The Queen Bee and the Origin of "Drone"
The de Havilland Queen Bee, introduced by the British Royal Navy in 1935, was the first reusable remote-controlled aircraft. Built as a target drone for anti-aircraft gunnery practice, the Queen Bee could be flown repeatedly, unlike expendable target aircraft before it. The name "drone" for unmanned aircraft is commonly attributed to the Queen Bee: the male honeybee (drone) does not work, just as these aircraft had no crew. Over 400 Queen Bees were built before production ended in 1943.
WWII and the Radioplane OQ-2
The Radioplane OQ-2, designed by Reginald Denny and first produced in 1939, became the first mass-produced unmanned aircraft in history. The U.S. military ordered nearly 15,000 of them during World War II as target drones for anti-aircraft training. A young Army photographer named David Conover visited the Radioplane factory in 1944 to photograph women working in the war effort and photographed Norma Jeane Dougherty on the assembly line. That photo led to a modeling career, and Norma Jeane became Marilyn Monroe.
