France Planning to Build a High Altitude UAV
France is planning to build a high altitude UAV that will be used for surveillance and could prove useful for NATO and the french military. A new project of an autonomous airship – a hybrid between a drone and a satellite – has been developed in France. The 'StratoBus' dirigible drone will be able to carry out long endurance observation operating at an altitude of about 20 kilometers. Designed to be between 70 and 100 meters long and 20 to 30 meters in diameter, made of carbon fiber, and equipped with two motors, the StratoBus will be able to operate at an altitude of about 20 kilometers in the lower reaches of the stratosphere – above air traffic and jet streams.   https://www.youtube.com/embed/Yy8B7Eirg6A
