Deck mounts for 24cm guns? Ouch! I feel for the gun crew already.

In 1877, most mounts are really what we'd consider 'deck mounts'- including some of the muzzle loaders that have to have a block & tackle and some tongs to load the shell with!

SS2 because this is an old PC with just SS2

Terrible ala Rochambeau (ex USS Dudenberg)
The idea is to built a light BB with medium guns in battery with better rate of fire.

Cart is wright, no hoist at this time, just tackle.

What SS3 to download?

SS3 in progress for Terrible class...

I have found some characs about the French 340mm gun for Dévastation

340 mm mod. 1875 de 21 cal, citadel installation, hydrauliques Farcot mounts, pointage + 7°/-5°, Rof 8 minutes, hydraulic tackle.

ROF...8 minutes !!!

We have enough time to go to the store-room, drinking a beer ... a fresh Guinness, for example !!!

Yeah- those old large caliber guns are hilariously slow.
Unfortunately, some people refuse to believe just how slow.

EDIT: here is a great page on how slowly they actually fired; check out the load times on the guns for H.M.S. Inflexible and the Caio Duilio... between 11 and 15 minutes PER SHELL!

The SS3 report says the 9.45-inch guns are in 2 twin Coles/Ericsson turrets (A/Y) but the drawing seems to indicate 4 single open barbettes (A/Y and 2 beam barbettes).

I do like the drawing however.

Actualy, the 1865 3rd class BB CERBERE is between 4200t - 4700t with some variations...
I made the drawing of the 4400t type with 4M1x240

The SS3 posted is with T2x240 mlle 1865 drawing by the famous ingenior Dupuy de Lome.
