Eli5: How are submarine deck guns able to still be fired after being submerged in salt water?
In: 5399
You might be thinking too much into it. The only bit exposed to the sea water is the barrel. Literally a hollow tube. Precision engineered, but still just a hollow tube. We can paint it with special paint and grease it up. Then regular maintenance takes care of the rest. Sailors are kept busy at all times to prevent boredom. If they ain’t mopping up they are probably painting and waterproofing and re waterproofing and cleaning.
