Looks like fun. Of course, I imagine if they were doing it for keepsies it wouldn't be under daylight conditions, which would tend to diminish the fun factor a bit...

NO, but I don't know the specific radar inside that dome.
Perhaps aircraft landing guidance/glide slope?
The two visible CIWS are the two "H" -shaped weapons (think of an "=" sign with a white dot in the middle) on both sides of the flight deck: The CIWS radar dome (from above) is roughly 36" in diameter, the CIWS platform is square and has two radar electronics enclosures below the white dome.
Gin sticks out below the dome.
