Unmanned Aerial Vehicles (UAVs) are automated flying planes currently focused on military and civilian applications. This work simulates the motion of UAV in the battlefield environment; making use of the theoretical conditions for the design of real systems. The design of the algorithm is scalable to specify the number of UAVs involving in the mission. The coordinated flights of the UAVs with each other enable them to arrive at the enemy target at the same time. The simulation is based on real flight conditions with some assumption. The snapshot of the results show the different scenarios when only one or more than one UAV(s) participate in the mission arriving from different angles spaced equally to hit the target. The design of the simulation also allows to specify an enemy zone, which is a circular area from the target in which the UAVs enter the zone at the same time.
