1915 - T2x12" for Byzantine Empire

Jefgte · October 01, 2020, 04:53:00 PM

Well, in 1915, Byzantine Empire could use T2x12" on class of "Warship " but what kind of Warship?

A modern PDn for colonial use? a kind of super Monitor...
A little Battleship? (USS Michigan)
A light Battle cruiser? (HMS Invincible)
...

I'd like her better with "B" turret superfiring, but it's otherwise not a bad combo of firepower, speed, and armor.

The 20% coal is a "cruise on cheap fuel" option?

maddox · October 02, 2020, 12:46:35 PM

A Dunkerque would be more fun to my thinking.

The 2 tripple 12" forward, like Rocky wrotes.

TacCovert4 · October 02, 2020, 03:21:50 PM

6 x AA guns? That's a lot of AA firepower.

QuoteThe 2 tripple 12" forward

I have not T3x12" I have just T2x12"

Quote6 x AA guns? That's a lot of AA firepower.

This high angle gun could be use also vs TB

Within your role and weight restrictions, I'd say that 4x2 would be better than having a faster ship with 3 x 2. Unless you need a light battlecruiser. Just noting that you've been mentioning monitor and colonial service stuff for this build.

I think that with the 1915 techno, I could SS a 16000t-24kts USS Michigan.

Anything listed as an AA mount would, IMO based on the inclusion of DP guns later in the Capital Architecture, would not be able to be used as LA weapons for anti-TB work.

Traditionally the mountings could bear on the water surface.
The thing about higher elevations is the breech lowers, making recoil and reloading space difficult. So HA/DP/AA mountings have to be different and higher than anti-surface work.

That said, AA mountings will not be integrated into the Anti-surface fire control until that "DP gun" tech level, and so be functionally very limited beyond 3000m, possibly even causing an overall negative for the extra splashes.

I would generally agree with this. Historically in the USN, the 5in AA gunners would compete in surface gunnery competition. But in a battle that would be more of a last resort. Might make a mild difference with smaller craft though.
