Drones and fighter jets crossing continents without anyone noticing?


It is called graphene and is an ultra-light “black powder”, but what makes it exceptionally valuable is the ability it gives to drones or fighter jets coated with it to become invisible to enemy radar.

This innovative idea has one of its state-of-the-art laboratories in Portugal.
