Ooh, pretty.

[Kaiser Kirk]

I agree with Rocky.
Makes me wish I had built a training cruiser. I was thinking of 'retiring' one of my Armored Frigates that way.
Rebuilding as part of the Prebuild is cheap- as it's only BP.

Anyhow, the last ships look good.
Cool. Japan is about ready :)

[Desertfox]

That should do it for Japanese ships, 4.3 BP left, which I will assume is lost (rounding errors)/used on refits (FC)/spare for minor modifications to the ships as I fix some minor issues.

[Kaiser Kirk]

Sounds good.
Pretty solid fleet in the end, despite the NPC hinderances you had to endure.
I expect it will blossom to cause concern and heartburn for all those in range :)

[Desertfox]

To be fair, its a lot more balanced and capable of expeditionary missions than if I had been able to build dreadnoughts. Four dreadnoughts would have easily burned up to a third of the available tonnage. Now I have a ton of torpedo boats, cruisers, and auxiliaries to throw at anyone...
