A great AC. I particularly like your innovative superfiring turret arrangement, though this would, by necessity render the vessel obsolete by the time of launching and commissioning, since design work cannot have been implemented earlier than ca. 1903/04, due to the superfiring arrangement.
Well, that was actually a problem for many classes of warships around that time period, they were obsolete as soon as their hulls touched saltwater. There was actually some work done with superfiring turrets earlier, though, such as the French Battleship Henry IV launched in 1899. It was, admittedly, a secondary gun superfiring over a main gun. The US Virginia class had a form of superfiring as well with the 8" fore and aft turrets actually sitting on top of the 12" turrets, and they were laid down in 1902. But, yeah, obsolete on launch is a good way to describe the Ajax Class. But with a nice little punch nonetheless.
I'd also add one or two steam launches/pinnases to your boat complement, and, finally swap out the four-inches for, say three-inches instead, since you've got a6"-secondary battery (splash interference problems).
Good ideas, both of them. I'll swap the 4's out for 3's. Adding a steam launch makes sense too. Maybe I can save time and just say the launch is stored on the port side.
Your funnels as built will create smoke interference, but you can heighten them in a later version, so it's ok.
Raising the funnels is no problem. I kept them a little lower because I thought if they were taller the smoke might interfere with the aft tower and gun director, but I guess raising them would just help the smoke clear those though, right?
