Each airburst projectile includes one or more spinners (140, 140a-140d); each spinner has a sleeve or a tube (146), a number of radial partition plates (148, 148a-148d) extending from the sleeve/tube and an annular rear plate (144) connected to the sleeve. Adjacent partition plates thus form a compartment (150). Disposed in each compartment is a streamer or streamers (170,170a,170b), which are formed in a coiled-up state. When the airburst projectile is deployed into a flight path of a target UAV, the spinners (140, 140a-140d) are ejected and the streamers (170,170a,170b) are dispersed in the flight path to create a streamer cloud, so that a streamer may entangle with propellers of the UAV and bring down the UAV, or as a warning or fence marking shot.
