This rocket is generally similar to the other smoke rockets in this series, differing mainly in its payload. It also differs in that it has a circle of smoke ports in the base of the head, which allow the HC smoke to be blown out of the head on impact. Pressure of the HC smoke blows out the port covers after the base fuze sets off the HC gas. The HC smoke will issue for one minute after impact.
