Description from War Thunder event page:
"Gryphon-3" reconnaissance drone/loitering munition
A British-Israeli project of loitering munition/surveillance and reconnaissance drone. Being part of the "Hydra" complex, this drone is equipped with an encrypted module for broadcasting targets to the gunner-operator's active monitor. The drone works in both manual and automatic modes, maintaining the flight settings specified by the operator. The power plant is represented by a piezomagnetic engine with a push propeller; a multi-mode digital camera with interchangeable lenses is located in the nose of the drone. In the drone’s hull there is a shaped-charge warhead for destruction of armored vehicles and enemy fortifications.
Edit: The drone can now climb.
