It seems like for whatever reason they just haven't been able to get off the drawing board and onto active service anywhere.

The barrel erosion issue and the fact that current tech dont seem able to get small enough pulsed power source (e.g super capacitor) Is the main technological barrier.

The pulsed power source is especially important and not much discussed. Railguns does not directly draw power from battery or generator, but from a power source that can rapidly unleash power in say milisecond or microsecond time, this is where capacitor or other source e.g homopolar generator or marx generator play. Those pulsed power source in return be charged with the generator.

The big obstacle for current gen railguns is still accuracy. It can't fire any guided ammunitions since the high g-force during launch will destroy any electronic components. It doesn't have any rifles either and the only way to achieve a somewhat stable projectile is to launch APFSDS rounds similar to tank guns.

Well, for this one can design tho. Developments are ongoing. Tho yes current Guided artillery rounds only subjected to 10000-20000G While EM railgun, one can expect 40000G.

36000G resistant electronics package tho apparently demonstrated

Yeah from my understanding the thing that seemingly killed the US project was the barrel erosion problem which seemed like a materials science thing where they just couldn't physically make a barrel that could last long enough. However that was a while ago and I don't know much about railguns. Maybe somebody will get it working eventually but seemingly right now it's still stuck in development.

I'm not so sure, I believe US was able to get electronics that were rugged enough to tolerate firing from railgun. However again I don't know much about railguns and maybe they couldn't get it to reliable or it just cost too much.

Although it has little to do with 055, I think putting electromagnetic guns on warships is a plan with no practical value. Even if it has a guidance system, what significance does a cannon designed to attack targets around 200km away have for the navy of the new century? Anti-ship? There are few chances for a warship to fire all four anti-ship missiles in its lifetime - unless it is launching a DF17 with a range of 1,500 km. air defense? The chances of the electromagnetic gun being able to see a high-altitude fighter are almost zero. Land attacks have been replaced by cruise missiles that cost tens of thousands of dollars and are always hovering.
The electromagnetic gun has only one use, which is to be deployed as a railway gun along the coast of Fujian to deliver cheap and sufficient ammunition to Taiwan Island.

Does anybody know what these objects that look like white barrels are? Seems like 6 on each side.
