To answer staggerwing at least for USN assets they would typically have some combination of these air search RADARs depending on the type of ship.
Some common examples:
AN/SPY-1

250nm+ range in general with the SPY-1 and SPS-48 being phased array height finding RADARs.
I have a piece of SPS-49 antenna that I had to cut off with a hacksaw sitting on my desk.
