Re: Richelieu and Jean Bart

Well, instead of having 1.33 salvos per minute with 1km dispersion, perhaps they preffered 0.5 salvos per minute with 200m dispersion. That way at least they had an honest chance of hitting. (Hypothetical numbers used !)

Re: Richelieu and Jean Bart

Also, the timeframe of Jean Bart's salvoes on Nov 10th was between 11:41 to 11:51AM, or 10 minutes to fire 10 salvos. That's a round 1 minute/salvo, and, as each salvo had 2 guns, it means each gun fired 5 shells, therefore "rate of fire" was 1 shell/2 minutes/gun, or 0.5 shells/minute/gun - a very ...

Re: Richelieu and Jean Bart

IMHO problems of rate of fire become manifest some time later in the shooting battle. For a few shots fired per gun, it is probable that the shells were already inside the turret, or stored immediately below it. Same for powder cartrdiges. As Jean Bart fired a reported 10 double salvos, that means 2...

Re: Richelieu and Jean Bart

Indeed, that table is one of the references I've been using. Given the basis of Italian gunnery was on turret salvoes, I think it's safe to assume all recorded figures are for 3-gun turret salvoes. I do wish more information was provided in regards to number of rounds/salvoes fired, and what the co...

Re: Teleportation in time: Bismarck swap with IJN Yamato

Yamato's fire control was not in any way shape, or form, bad, certainly no less accurate than other navies yet you seem to grant her much lower hit rates than that of the RN. In your simulation, the RN lands multiple crippling hits while Yamato lands all of 2 hits. This seems very lop sided and imp...

Re: Richelieu and Jean Bart

you are right re. fuel, but here the extraordinary efficiency of the French evaporating system comes in play, while the Italian one was quite inefficient, giving a range of only 4000 miles @ 20 knots to the Littorio's, while AFAIK Richelieu was accredited of 7500 miles at the same speed. ... I seem...

Re: Richelieu and Jean Bart

Littorio's ships main shortcoming was their very limited range (not considered so important for their Mediterranean only usage). Littorio carried about the same amount of fuel as KGV class did - some 4100 tons - not far from the 4500 tons war load of Richelieu class. Thus , I think the range of the...

Re: Richelieu and Jean Bart

As far as dispersion is concerned, I think it's hard to compare to the Littorio -class as that varied depending on the point of the war. The best example of bad dispersion certainly would come from early 1941 for the RN Vittorio Veneto . Especially because she fought an action (the Cape Matapan/Enc...

Re: Richelieu and Jean Bart

While I still consider KGV a better fighting ship (harder to tell, both have pronounced advantages and disadvantages), the speed and range of the French ship are attractive. Also, the main artillery layout has its advantages if forcing combat on an unwilling enemy is a likely scenario. ... From wha...

Re: Richelieu and Jean Bart

In 1948, when delay coils were installed, maximum dispersion at 25 km was reduced from 1710 meters (6.84%) to 577 meters (2.31%) - although I'm not sure if these numbers refer to a full turret salvo, a full eight-gun broadside, or something else. I stand corrected then. From the above, I take that ...

Re: Richelieu and Jean Bart

I was thinking of the overall condition of Richelieu.

In late-1943, when she was finally fully operational, her dispersion issues had been corrected, but her ballistic performance was different from the original one.

Re: Richelieu and Jean Bart

… Problems existed with the 380mm shells in themselves. Richelieu suffered a shell explosion inside the barrel , in 1940. The problem was traced back to shell design, with additional troubles caused by excessive pressure in the barel caused by the powder cartridge ignition - but due to the war, the ...

Re: Bismarck's armor against long range hits

I don't understand the cruiser part.....
Was the 8cm portion thicker to protect against 8" gunfire ?

shortly after this report they published target properties of Tirpitz as following vertical side armour 12 inches deck armour 6 inches (as far as i remember correctly in SUPP 6-481) with the note that no british battleship shell available at the time was able to defeat 6 inches of horizontal protec...
