CIA Robo-Bug: Why US Never Used Its Super Micro Drone That Flew Like A Dragonfly To Track Enemies

In the intriguing world of espionage technology, a fascinating relic from the Cold War era emerges – the CIA's "Insectothopter." This super micro drone, designed to mimic a dragonfly's flight, was a remarkable feat of engineering. However, it never saw active duty. Let's dive into this captivating piece of history.

The Birth of Insectothopter

Developed by the CIA's Office of Research and Development in the 1970s, the Insectothopter marked a groundbreaking achievement. It was the first-ever flight of an insect-sized vehicle, a micro unmanned aerial vehicle (UAV). The primary objective was to validate the concept of using miniature platforms for intelligence collection.

During this period, microprocessors were still in their infancy, making the Insectothopter's development a remarkable feat of engineering. The project remained shrouded in secrecy until 2020, when the CIA finally released documents detailing its creation.

A Unique Choice: The Dragonfly

Initially considering a bumblebee for the project, Don Resier, the deputy head of the CIA's Office of Research and Development, faced challenges due to the bee's erratic flying patterns. The need for a stable insect led to an unexpected choice – the dragonfly.

With their simple aerodynamics and gliding capabilities, Dragonflies proved to be ideal candidates. They could move quickly and conserve energy during long flights, making them an excellent choice for covert missions.

Engineering the Insectothopter

One of the key challenges was replicating the dragonfly's rapid wing flapping, which occurred at an astounding rate of 1800 times per minute. Scientists turned to a small fluidic oscillator powered by gas emitted from lithium nitrate crystals to mimic this motion.

To carry the necessary payload, additional thrust was essential. This was achieved by venting the exhaust backwards, akin to jet propulsion.

Inspired by the dragonfly's appearance, the Insectothopter received a paint job that mirrored its natural counterpart. It weighed less than a gram and featured glittering eyes made of retroreflector beads, perfect for covert surveillance.

Control and Navigation

To control and monitor the Insectothopter, scientists employed a portable laser unit called ROME. This unit emitted an invisible infrared beam, which heated a bimetallic strip holding the dragonfly's exhaust.

Thanks to its gas-pumped engine and laser navigation, the Insectothopter could fly for up to 60 seconds. It lacked landing gear and was designed as a "crash and perch" device. While it performed well in laboratory tests, achieving controlled powered flight remained elusive.

The Mysterious Conclusion

Despite the project's success in meeting its goals, the Insectothopter was never utilized in any CIA missions. Its existence remained hidden from the public eye until recently. The project's ultimate fate and the reasons behind its shelving remain a mystery known only to the U.S. government.

In the annals of espionage technology, the Insectothopter is a testament to human ingenuity and the quest for innovative surveillance methods. While it may not have taken flight in the field, its legacy as a micro drone mimicking a dragonfly's grace is a captivating piece of history.
