Abstract: The present invention relates to the field of unmanned air vehicles, more commonly designated drone. More specifically, the invention applies to an armed drone system (10), notably equipped with a firing device and a steerable optronics ball (B) comprising means of illuminating targets (C). The invention proposes that the firing device be oriented towards the rear, so as to reduce the problems of masking of the optronics ball (B) by elements located in its line of sight, such as a front wheel (FW) for example. Moreover, because of operational use involving a phase (10S) for firing weapons and illuminating the target (C) from the back, the armed drone (10) moving away from the target, the vulnerability of the drone (10) is lessened.
