4. FULMAR X
The FULMAR X is a small-scale stealth drone technology product reflecting Spanish ingenuity. With a wingspan of 3.2 meters and weight of just 19 pounds, this little platform keeps great endurance capacity while including sophisticated stealth elements. Its aircraft has well slanted surfaces that divert radar waves away from receivers and uses radar-absorbing materials. While its modular architecture lets the drone be rapidly deployed and recovered, its electric propulsion system runs with no aural signature. Though compact, it has advanced electro-optical and infrared sensors for day and night operations.
