About Sky Dew
- Sky Dew is a massive balloon-like structure in the shape of a puffed aircraft.
- The high-altitude observation balloon acts as a detection radar blip for small unmanned aircraft and cruise missiles.
- It is one of the largest aerial threat warning systems in the world.
- The technology has been jointly developed by Israel Defense and US company TCOM. The project was entirely funded by the U.S. Department of Defence.
- The Israel Air Force was handed over the Sky Dew in 2022.
- The system comprises a blimp capable of flying at high altitudes with radar and detection systems to scan a wide range in any direction.

- It can carry 7,000 pounds and has an operational altitude of 10,000 feet.
- It offers a significant advantage in its ability to remain in surveillance for extended periods without needing fuel or crew replacement.Â
Q1) What is a RADAR?
RADAR stands for Radio Detection and Ranging System. It is basically an electromagnetic system used to detect the location and distance of an object from the point where the RADAR is placed. It works by radiating energy into space and monitoring the echo or reflected signal from the objects.
