Western sources tend to refer to the ships as battlecruisers due to their large size, high speed from combined nuclear and oil propulsion, and very heavy missile/gun armament.

Thanks for the info I suppose separate phased array radars are all tracking different targets.

I was wondering why the top one was tilted slightly?

The top two radars (on the foremast) are almost certainly search radars. Why the one is tilted I don't know.

The two radars on the mainmast (further aft and shorter than the foremast) might be phased arrays, but also look like they can be mechanically rotated. Seems very strange to burn money on a phased array system and then make it mechanically steerable... Regardless they are two-dimensional (rectangular) which means they can electrically steer the beam both horizontally and vertically. That makes them most likely air warfare (SAM) fire control radars. Possibly with air search function like the U.S. AEGIS radars.

There are no other obvious phased arrays but they could be hiding inside weather domes, like the testbed AEGIS radar used for tornado tracking.

Hopefully some poalarbear is familiar with RU equipment and can comment.

I think they rotate them to track targets as the beam is narrow?

seems a bit like this: https://en.wikipedia.org/wiki/AN/SPS-48

maybe if they are tilted, the side lobes from the array signal would cover different areas and you'd gain some technical benefit from this? Dunno https://cdn.comsol.com/wordpress/sites/1/2019/04/COMSOL_Blog_ModelImgs_AntennaArray_CoverImg.png
