A military university in China has unveiled a microscopic drone that resembles a mosquito and is designed for covert intelligence work. The device weighs less than 0.3 grams, and its wings flap 500 times per second, allowing it to move much like a real insect and hover accurately in the air.
Because of its tiny size, the drone is almost invisible to the naked eye and can slip past radar detection. It is also built to enter places conventional drones cannot reach, including interior spaces inside buildings and crowded urban environments. The article says its mission is to carry out covert operations where stealth is essential.
Despite its advanced design, the drone still faces major technical limits. Its miniature size means battery life is very short, and it is highly vulnerable to wind gusts that could knock it off course. Even so, the report presents it as a significant leap in surveillance technology and a sign that the smallest objects may pose the biggest modern security threat.
