They pass temporarily out of frame then hit the water and explode!!
UrsusArctos: The weapon that's firing from the vessel in the foreground looks like an ASROC Anti-Submarine rocket launcher, but those have eight barrels, not four, so I'm not sure what I'm looking at here. The vessel seen in the background is an American California-class nuclear guided missile cruiser, although I can't tell if it's California or South Carolina without the hull number (It's also missing the "Christmas Tree" antennae at the bow). There appears to be a second California on the left side of the images in 119a and b, which means both the sisters are present for this shot. In real life, their nuclear reactors made them highly expensive to run and the conventional Ticonderoga-class cruisers could do a better job for a lot cheaper, and they were decommissioned in 1999.
