What is spy balloon?

A spy balloon is an unmanned aerial vehicle (UAV) used for surveillance purposes. It is used to gather intelligence, monitor activities, and provide real-time data for decision-making.

Spy balloons have been used for military surveillance since the early 20th century. The first successful deployment of a high-altitude spy balloon was by the US during the Cold War.

Types of Spy Balloons

Balloon Type


High Altitude Balloons

Can reach heights up to 100,000 feet. Used for long-term surveillance and communication purposes.

Aerial surveillance balloons

Used for short-term surveillance and real-time data collection. Can be deployed quickly in emergency situations and can provide a bird's eye view of the situation.

Stratospheric Balloons

These balloons can float in the stratosphere, about 50 km above the Earth's surface.  Used for communication and scientific research purposes.
