At a wild guess:
Corrosion resistant paint for steel is usually loaded with zinc. Radomes are usually glass fibre so don’t need corrosion protection, but metal loaded paint would interfere with the radar. If it were grey and your usual grey paint is zinc loaded, but you had a special grey for the radome then there would be a real danger that you’d end up with the wrong grey on the radome and you might not find out until it didn’t work.
So the grey radomes might indicate that the metal is coated and therefore the paint doesn’t need zinc in it so you can use it all over, or the navy feels that today’s ratings can be trusted to paint the right bit with the right paint, or the radome manufacturer is able to include grey pigment in the polymer matrix of the radome so it is still left unpainted but you can’t tell at a distance.

One of the reasons early Radomes were white was to keep the temperature within cool. More modern electronics does not generate so much heat and radomes can come in a variety of colours.
Metal based paint acts as an attenuator to high frequency radio waves, it is less of a problem at lower frequencies. Also finding a paint that will adhere to the surface without peeling can be a problem.

In the early 2000s the USN became more concerned with visual "sore spots" that might catch the eye of an optical sensor at long range or in otherwise low visibility. Additionally, there were concerns about how they effect a ship's IR signature and impacting other systems due to being more reflective than the rest of the ship. Gray radomes for the Phalanx were developed by Raytheon in response, and are becoming more common.

Wonder if HMS Oceans Phalanx will be transferred over to HMS Queen Elizabeth?

In March we will know.

I guess the rotation through factory, for 1B upgrades, has been completed, so direct transfers are a likelihood.

If anything that video shoes the need for Sea spear. A couple of Remote/Autonomous small boats have a chance of getting close enough to cause a problem. That remotely operated boat was still going after several attempts to stop it.

Only pic of a Wave with Phalanx fitted that I can recall, recently posted on @NavyLookout.

Both offset to starboard. I'm sure there's nothing to worry about.

So does this mean we have fifty systems now?

Not necessarily, this isn't an actual contract just the OK to buy.

Me too, until I read about 1B having a baseline 1 and baseline 2
- anyone know the difference?

Seems to read that by ow all of ours are 1B baseline 2
"have been upgraded to 1B Baseline 2 standard with kits supplied by Raytheon"
so my question about the difference is (sort of) irrelevant
- what has been gained, and how much that cuts into the need for/ relevance of the 30 mm's (for anti-surface) that we currently have, in addition, might still be a discussions point?
