Flying at low altitude and slow cruising, the FD15 is not easily detected by radar. Targets can be set in advance. After discovering the target, the FD15 will dive directly for autonomous attack. It is also possible to install an elector-optical pod and discover valuable targets by cruising and flying over the target area , and then the FD15 can carry out autonomous attacks, or carry out precise strikes based on manual instructions. Using commercial off the shelf components, the cost is low, while the interception cost is very high.
