1. An elongate, powerable, expanding fin aerial rocket comprising:
a body having a fore end for containing a warhead and an aft end opposed thereto, the aft end having at least one autonomously radially expandable fin joined thereto, the at least one fin being biased to expand outwardly from a collapsed position juxtaposed with the body to an extended position outward of the body; and
a sleeve removably installed over the at least one fin in the collapsed position, the sleeve restraining the at least one fin in the collapsed position and being removable to allow the at least one fin to expand outwardly from the body, the sleeve having an inner surface oriented towards the body and outer surface opposed thereto, the inner surface of the sleeve being conductive whereby a charge occurring proximate the at least one fin is grounded to prevent ignition of a motor at the aft end of the rocket.
