I recommend "Dreadnought Gunnery and the Battle of Jutland" by John Brooks for a more up to date view of fire control capabilities and the degree to which Admiralty FC systems were influenced by Pollen. There's also some discussion of the Argo's capabilities at "The Dreadnought Projec...

Hindsight isn't necessarily a good guide; hindsight expects base fuses with reliable delay action, effective fire control and respectable rates of fire for heavy guns. Given that 6-in Krupp armour was basically proof against any service AP round up to say 1910 (we can bicker about the date), then it...

But the German ships would still have to come within range of the 12 inch to engage?
Why?

Oops...

From the above mentioned report: "Restricted letter from US Technical Mission in Europe to CNO (OP-16-PT) of 27 August 1945, serial 850, forwarded blueprints of starred projectiles shown in Fig. 1". The the 28cm L3.2 is marked with an asterisk so there are (were) blueprints in the US archi...

I develop specific Cd curves based upon projectile shape and pressure distribution around the projectile as various speeds. It's a bit more reliable than trying to guess at form factors and drag functions. May I ask where you are deriving the 3.2-cal vs. 3.4-cal information from? It sounds like a c...

I am of the opinion that 280mm psgr and spgr (and 380mm for that matter) are simply scaled down (or scaled up) versions of the 305mm shells. But I don't know this for certain, and would therefore like to find images or better scale drawings of 280mm psgr. I am interested in accurate information on ...

Terminology

Terminology is specific to time and place. I don't think you'd find any such terminology in a British Admiralty document of WW2 or earlier, I haven't seen enough USN ones to know what they were doing. My interpretation is that although they would recognise the concepts these terms represent a conven...

Actually, after messing about with the rifle in Powerpoint I think I could happily reverse my conclusions - but all the same I think you're more likely to achieve a result with the rifle and the man than with the belt buckle.

I disagree, the shell base is more or less in line with his toes so he's in line or a little behind the nearest one. Unless he's a giant, the fact that the one nearest him comes to his waist makes it about 40-in tall unless he's very, very tall. So it's either 30.5-cm APC or 28-cm Spgr. The caps on ...

Tiornu isn't stating an opinion, he's stating a fact. C/34 was the official designation of the gun.

Standardisation years bear no relation to the year a given gun actually went to sea, the most blatant example is probably the WW1 Blucher's 21-cm C/01.

What?!

That means most libraries won't have one either! I can't believe they can cover their costs on that many. I know it's minority interest but that's ridiculous.

Still, at least it means I should be able to retire when I sell mine...
