The Federated Nations of Kravon developed the Songbird drone. Made to be easy to produce, build and repair these could be used in greater numbers than most other drones.
About this creation
The low cost do have a negative impact on the performance of the drone. Simply because the programming is very low tech it can't think of it's own. These drones always need to have a relay station which guides them to the targets.
It's weapons may vary from mission type. The most common drone has 8 high explosive missiles, but it can also carry anti tank missiles, or anti air guided missiles.
The front where the 'eye' is located can open to form a radar dish. This can only be done when it's traveling low-speed, since it would cause to much drag when flying at high velocities.
