UK has some interesting paint jobs.
I guess the question comes down to how much do you paint it black, and then won't it stand out and look very odd. Here on the UK Destroyers, they seem to only paint the trailing surface.
I would also assume the black paint would likely absorb more sun light energy. Maybe it can't be painted black?
Maybe black on the tail surface, dark grey at the sides, light grey at the front would be a compromise. I think that could look quite neat.
Also how big our Hull numbers? Were they always so comparatively massive.
I do like the look of the upgrade Anzacs. For a comparatively small ship, they look a lot beefier now. With their massive hot rodded radar, harpoons out the front and the new 5".
I wonder if its worth redesigning the funnels, the ovaloid curved pipes can't be good for radar signature, and I would assume something could be done in terms of flow.
