I have question to all warship experts here. Can you tell me what is the name of this object and the purpose of it?
As you can see in these images below, the objects I'm talking about located near gun turrets in front and rear ship. They have different shape, one is just straight line, other is half circular.
What are they? Also, could you please provide me with the real photographs of those objects? Are they present only in some ship, for example exclusively built for British RN?
