Edit: Had to repost due to issues, I apologize.
My interest was recently piqued regarding the performance of large artillery during extended use, especially the guns aboard battleships. I have been unable to find even cursory information regarding how heat affected the handling, aiming, and firing during, for example, an extended engagement between two battleships.
I'd imagine any concerns regarding barrel heat or wear would be disregarded during an engagement, but how did that affect the performance of the guns over time?
Did the barrels experience any warp after enough rounds were fired in rapid succession?
How long until a crewmember could safetly touch the outside of a barrel after it had fired in rapid succession?
Did heat affect the potential fire rate of battleships during an engagement or bombardment?
Any information or further reading would be extraordinarily appreciated! I'd love to learn more on this topic and how it was managed, or if it was even a concern! Thank you.
While not explicitly about the temperatures of gun barrels, this answer from u/thefourthmaninaboat provides some information about wear and tear on battleship guns.
This answer from u/wotanweevil also includes some detail about replacing the gun barrels.
