Coils on deck gun?
What are the coils on the deck gun for? Are they wire for some kind of degaussing, or are they for cooling or some other reason?

If they're the same as the ones on the periscope, it's to eliminate vibration when submerged.....IIRC.

If you are talking about the coils that parallel the gun barrel, those are for recoil. You wouldn't want a hard-mounted gun on the sub deck, since it would pull out of its mounting location after a few shots. The springs absorb the barrel as it "slides" along its carriage. The springs help cushion the shock from the gun explosion, and then pull the barrel back into position for the next shot.

Anti-Vortex device. On the periscope they were used to eliminate the vortex effect of the water rushing around the scope at speeds of 6 knots and higher, and shaking the daylights ot of them.
Apparently also used on antennas, to keep them stable in high wind. I'm guessing its the muzzle cap lanyard though, that just looks like a solid coil in the game rendering. |
I can't recall ever seeing this before. Can anyone provide period photos of this?

Ah. So this appears to be more of a u-boat, rather than fleet boat, thing.
I'm no expert, but the vortex explanation seems reasonable. However: The periscope is perpendicular to the water flow, while the gun barrel would be parallel to it. Would the same mechanism work for both? |

I think it's just a bad graphical rendering of the lanyard/rope that secures the muzzle cap/plug to the deck gun platform to prevent its loss overboard. |

Think it was a actual coil of metal wire... that had a bit, of a spring to it... sort of like how a slinky does... when the gun plug was needed, would stretch out so the plug could seal the end of the barrel, keeping out the sea water. When the plug was removed so the gun could be used... the coil would retract, thereby keeping the plug, in a... stowed position... of sorts. :hmmm: M. M. :Kaleun_Cheers: |
