Found a video at this sitethat shows an Arleigh-Burke class destroyer conducting some Combat System trials. They used high speed cameras for the missile and gun firings so you can actually see the projectiles leaving the canister or barrel. There are EO camera video of the rounds flying/hitting the target. The guy that posted the video is a Fire control man (not a fireman) on board USS STERRET DDG-104 the US Navy's latest destroyer.
