"Soon as we find that German battleship that's makin' such a fuss,
We gotta sink the", *singing very rapidly*, "Schlactshiffen Q 'cause the world depends on us!"

Looks good, but what's sitting immediately aft of turret Caesar?

[maddox]

Looks like a low set range finder.

;D

[The Rock Doctor]

I mean that long, linear dark grey thing.  Looks like a catapult, but it's an odd place for it if so.

[maddox]

Hm,  as it could be catapult we have a few problems.

Where's the crane to load the plane unto it?
Fun cleaning up the mess if the guns fire abaft, a catapult wasn't the most blast proof structure on a BB.

[Logi]

I don't think it is a catapult, his Misc. Weights don't include an airplane.

50t Construction Reserve Weight

50 tons is a lot of WW I vintage aircraft.

[Logi]

Doubt it, they don't even have the 1910 Seaplane tech, so I doubt they would have catapult.

Air intakes for the engine room directly under it.

[mentat]

Nice ship - plenty of everything - and pretty economical to boot

Have to be really picky to suggest anything - but here goes  ;)

- Sbt Qlty is rather low - possible to raise Freeboard a little to improve that?

Esp - quarterdeck - rather low for heavy seas - you have some sheer at the stern - but does not solve the problem fully



   

[The Bushranger]

Sweet. :D

I think using the "Centerline (distributed)" turret arrangement would work better than seperatly simming Q turret. :)

[Sachmle]

Decided that 28kts was a little fast for a BB when the rest of mine only do ~23kts..so I backed her down to almost 26kts...and added 2,000nm range, and 25mm deck armor, and 10mm barbette armor for a cost of 15mm of "other" armor on the turrets and 1 less TT. Used BR's idea on layout and saved 500t in the process. Same look so no new pic..

You could use the 20 tons for torpedoes to stow a launch with a torpedo tube...  :)

[Korpen]

A question about the picture; is not the turrets a bit too low? Going by the height of the hullbreak they seems to be just 2-2,5m high, looking at pictures of the IRL turrets on Baden I think about 3,5-4m would be closer to reality.

Nice picture otherwise. :)
