Rohan ships 1916, 1917, & Beyond

[Ithekro]

Have you tired to do triple turrets for the 15.5" yet?

I'll have to go back to my old Wesworld Chilean BB sims to see what can be done with 17" guns under 35,000 tons.  I know an 8 gun 17" job can be done on 40,000 tons, if you conserve weight someplace else.  This suggests a 6 guns ship with 17" guns, but could it be fast enough to be worth the cost?  (Repulse and Renown types as oppose to American trends with British undertones for Battlecruisers?  Or worse...Glorious/Furious types.)

[Valles]

Hmm... Layout-wise...

The secondaries - twenty 4.5" in eight mounts? Four twins and four triples? And if so, why?

[TexanCowboy]

lepeder proved that 18'' can be done at under 40,000 tons, so I wouldn't doubt it.

the tripple 15.5 is under development (aka not finished when that ship layed down) the next class actualy has 10X15.5" (course it will be a slow BB to)

Huh? its 20 guns in 10 twins, 4 mounts on each broadside, and one mount fore and aft raised over the MB just like asfaloth.

      16 - 4.50" / 114 mm guns (6 mounts), 45.56lbs / 20.67kg shells, 1918 Model
     Quick firing guns in deck mounts with hoists
     on side, evenly spread
      4 - 4.50" / 114 mm guns (2x2 guns), 45.56lbs / 20.67kg shells, 1918 Model
     Quick firing guns in deck mounts with hoists

[Tanthalas]

ok thats wierd, ill have to open it back up and look cause they should have been the same as Asfaloth 16 6uns in 8 mounts (I dont think it will realy matter as I had like 30 tons slop but IDK)

[Tanthalas]

this is a WTF moment, I know its not legit but I seriously dont know what happend with Spring Sharp.  Maddox sent me the Spring Sharp file for one of his BBs, after I fixed the keyboard issues I converted it to Standerd Mesure instead of Metric and Spring Sharp gave me this (I know you cant reproduce it on the listed light tonage but im staring at it on my Monitor)

[Ithekro]

quads and triples?

[Tanthalas]

quads and triples?

Yup 2 Triples SF over 2 Quads, like I said wierd ship kick.

[Guinness]

The recoil on the first one is way too high...

[Ithekro]

Aye, the captain wants to feel each blast in his spine.  Basically the first one can't fire all her guns on a broadside...at the same time anyway.

[Kaiser Kirk]

this is a WTF moment, I know its not legit but I seriously dont know what happend with Spring Sharp.  Maddox sent me the Spring Sharp file for one of his BBs, after I fixed the keyboard issues I converted it to Standerd Mesure instead of Metric and Spring Sharp gave me this (I know you cant reproduce it on the listed light tonage but im staring at it on my Monitor)

How odd. The hull fairly similar to my Wesworld Ijelsijk class, except those are 3x2 15" and 23knots...and 20 years later. I agree there is some issue there.

as for

Yup 2 Triples SF over 2 Quads, like I said wierd ship kick.

... I really like the look of twins over triples...not sure about triples over quads.

[maddox]

Kaiser Kirk, I never visited Wesworld, so I can't know that class you're talking about. I just labored on the original TAN has mangled a tad further, as my design was a few 100 tons heavier.
