Re: KGV + PoW

to ~40250 tonnes (J&D p.186) J/D page 186 contains only the reference to 'her new 'normal' displacement of 43600 tonnes'. See my post of Sun Sep 23, 2018 1:45 pm for an explanation of "normal displacement" via a direct quote from G&D p.148. This is what J&D stated on page 186: In machinery trials c...

Re: KGV + PoW

The KM estimated Richelieu's standard displacement as 46750 tons (47500 tonnes) and after her USA refit Richelieu's displacement was 47721 tons (48500 tonnes). So Richelieu was 1000 tonnes above the KM estimate. The KM did not estimate Richelieu std. disp at 46750, but at 35160 tons, with intermedi...

Re: KGV + PoW

You seem desperate to prove that a ship designed to far exceed the treaty limits (by KM admission, at least by 7000 tonnes) isn't really bigger than ships that tried to meet the treaty limit. :dance: You seem to lack basic arithmethic skills. A ship with a std. displacement of ~37800tons in June 19...

Re: KGV + PoW

See G&D page 98 and 148(below). Richelieu fuel capacity was 6796 tons in Nov 1943 after her USA refit. Full load was 47721 tons and after removing fuel and reserve feed water and LIQUIDS we get ~40000 tons . LIQUIDS. Liquids such as these: Propulsion fuel oil (0.852): (diesel) 527 tonnes Lubricatin...

Re: KGV + PoW

J&D state 5866 tonnes of fuel (p.99) No, J/D give 5866 tonnes of fuel in PEACE TIME , and 4500 tonnes of fuel in wartime to maximize the effectiveness of the underwater protection system (pg 118). Why haven't you presented this above ? I know this is difficult for you to understand, but page 118 de...

Re: KGV + PoW

Removing fuel and reserve feed water = standard displacement!!! So you compare one battleship with NO liquids inside with another battleship at STANDARD displacement ? Standard Displacement: 1) The standard displacement of a warship was defined in the Washington Naval Treaty of 1922 as the displace...

Re: Anson and Tirpitz

284P was not deployed. They decided to wait until 274 was available instead. I'm not sure why you'd think that. Anyways I've identified type 284P4 on several cruisers via their action reports in Glasgow, Black Prince and Diadem. I suspect that policy might have been to upgrade 284 to 284M but Anson...

And what is the displacement of Tirpitz in 1943 after removing fuel and reserve feed water and liquids.... ?
Removing fuel and reserve feed water = standard displacement!!!

Re: KGV + PoW

Richelieu had many additions by Nov 1943 including a huge increase in AA armament. She carried 7500 tonnes of fuel according to the KM study, plus reserve feedwater and diesel so her standard displacement was still under 40000 tons. It seems you entered the lack of comprehension dubious gang ? KM s...

Re: Anson and Tirpitz

Thanks Dave, I think you may well be right, however with 10 guns v 8 (and all firing properly!) would Anson not cause an immense amount of damage to Tirpitz's upperworks, including her radar, fire control systems etc even though her shells might not actually penetrate the main armour, in a similar ...

Re: KGV + PoW

G&D state Bismarck's full load displacement as 52360 tons ( 53200 tonnes ) which is close to the KM figures for their comparison of Richelieu and Bismarck. I know. The huge full load displacement comes mainly from the large (by contemporary standards) fuel oil supply + drinking water , washing wate...

Re: KGV + PoW

for their comparison of Richelieu and Bismarck. Remember KM did not know the status in which Richelieu was. Richelieu was completed and finally declared fit for service only in Nov 1943, when she was >43.000 long tons standard and 47500 long tons full load. Thus she was practically the same std. di...
