The deck gun... how did they ?

I would imagine alot of brass was used in the construction too, good point though - would be interesting to see how long it takes to get operational after surfacing:hmm:

Assuming it was packed with cosmoline or something, I imaging clearing the gun for action might take a few minutes (swab out the barrel, etc).

I just found this refering to the 20mm..

" Pressure-proof storage was provided for these guns, but it was found that they could tolerate immersion reasonable well provided the barrels were changed frequently."

Prolly explains why I see 2 guns strapped to the wall in the conn.

Deck guns on subs were usually equipped with a tompion (basically a plug which either screwed or clamped to the muzzle of the gun). If you look closely at many pictures of subs with a deck gun, you'll see it in place, often with a lanyard attached to it which is usually spiralled along the barrel to keep it from fouling stuff. Liberal coatings of grease would help too and I assume that other methods to prevent corrosion would also be used. One such method is the use of sacrificial annode plugs - you see these in use on the props of modern submarines where more than one material is used, the plugs giving themselves up to corrosion in order to prevent the important bits from corroding in the salt water.

On the other hand, I could be wrong:

The Mark 17 was a "wet mount" version for submarines and was unusual in that it did not require breech or muzzle plugs. This was because it used a special liner resistant to corrosion from sea water and could thus be submerged and flooded without harm to the gun.

Theres not a whole lot of difference between pee and saltwater except for the amonia.
