[The Rock Doctor]

Think the BB has extra twin mounts on the side?  Other than that, it looks capable.

[Kaiser Kirk]

Dreadnaught did, as did Nassau.

I would presume planning for Cross deck fire,
for which side ends works better.

Tough little nugget, decently matched to it's
Aztec counterpart of the era.
Flores is interesting,
The T3, the Hydrophones can be assumed refitted,
presumably bought from Iberia.
