How is a "gun platform" defined?

The ROKS Dokdo has a Goalkeeper CIWS on the bow, which has a GAU-8/A Avenger 30mm cannon in it (same gun that is used on the A-10):

Really? I thought that was just a fourth helicopter from an odd angle.

In the screenshot you can make out the horizontal search Radar on the diagonal outrigger, along with the forward facing tracking radar above the gun itself. I have seen a few Goalkeepers up close so recognised it easily. However, and easier way to ID it is to just google the ship and you can see that it is a CIWS and not a helicopter:

There are actually two Goalkeeper mounts, another is on the rear of the island. I'm guessing the bow mount will have to go if the ROKN ever gets F-35Bs for the ship.

And in the caption you can point out it also has a visible RIM-116 Rolling Airframe Missile box launcher on top of the island.

I reckon there is enough room to keep the one on the bow. Assuming they would have to put in a ski jump for the F35Bdown the port side, would end up looking like the British ''Invincible'' class.

That's the thing, I don't think they'll go the ski-jump route. If these are supposed to be amphibious assault ships, a ski jump would block off a lot of real estate on the deck. The US Navy doesn't go with ski jumps on their assault ships for exactly that reason. (And ever since I was a kid, I've been wondering why no one has ever developed a hydraulic ski jump that folds into the deck when not in use.

Ski jumps are not just a straight ramp that can fold down flat against the deck, they are a smooth curve from horizontal to the desired angle. If they weren't a curve, there would be a big impact and stress on the gear of the plane when it hit the start of the ramp, and it would probably bottom out or tip over or something else not very good. Due to the fact it is curved, there is no practical way of folding it.

The reason that the Wasp class can launch Harriers without a ski jump is the fact that they have a rectangular flight deck. If you tried to launch off of a Dokdo, one wheel would leave the deck before the other which is not a good idea (you could take off from the stern, but to do this you would use a lot more fuel as you would need a take off speed that was about 40 knots faster relative to the deck). Generally launching without a jump is a compromise, as more fuel is required along with a longer run up (meaning that you could park less aircraft and have fewer landing slots leading to slower flight ops). A ski jump would not take up that much space (probably only one parking space) as a large portion of it would be off of the current deck area on an enlarged superstructure. If they convert it, it will depend on whether they want it to remain primarily as an assault ship, or turn it into a carrier.

Back to the topic, I Have never used the gun/weapon platform category, can someone point me to a good example page where it has been used correctly?
