I like the photo of the gun from Chester - thanks. I have a photograph somewhere of a 12 inch gun, taken at "Explosion!" in Portsmouth, the museum of Naval Ordnance - all 150 tons of it! If I can find it, I'll scan and post it. There really was some large-scale engineering on warships around the time of WWI!!
Incidentally, ironically, if 1 or even 2 12 inch shells from Derfflinger had hit Ardent, they probably wouldn't have sunk it, but almost certainly have gone straight through - the impact with the thin plates wouldn't have triggered the fuses! Destroyers were quite hard to sink with shellfire; in one of my books there is a photograph of a destroyer with all its bow section blown off, still afloat and level. Its 4 inch shells would have bounced off the Krupp armour on Derfflinger; if you wonder why the German ship opened fire, it's because the role of destroyers in WWI was to fire torpedoes at battleships, so it would have been risky to ignore it. Having said that, surface-ship deployed torpedoes in WWI were notoriously inaccurate, with only about 1% finding their target. Whitehead torpedoes were also slow and had very limited range compared to the type used in WWII, giving their targets plenty of time to turn out of the way. At the same time, British fuses were also notoriously unreliable, with only some 55% working as intended!
This may not be the right thread, but if anyone is interested, I can talk post quite a bit more about naval technology of that period.
