I agree on the reduction in weapons on the cutter vs. the corvette.
On the corvette itself, I would standardized on either an ESSM/Standard missile combo, or the Barak 1/8 combo. The original design included both, but that was for Israel, which builds the later, and could buy the former (although, on such a hull, I doubt they would*). As for the timeline, I actually don't see a War of 1812 analog happening, simply because the weakness in the US fleet that was caused by the Jeffersonians can't happen here (The Jeffersonians wanted to decrease the fleet so that US trade wouldn't be a think, forcing New England traders to become farmers). This has little impact downstream, but was something I thought should be said.
In fact, I'd expect a MU fleet to be historically based around trade protection, and long range, expeditionary conflict (with the exceptions of possible conflicts around the Saint Lawrence Sea Way and the Chesapeake bay. Both of those however, would favor air power. The exact disposition of forces on the great lakes is something that I'd think you would want to evaluate (with respect to any MU/UK/USN(orth)A treaties.
*The Israelis might, but their navy is crazy, and not in a good way.
Okay, so I got rid of all the missiles on the corvette except for the ESSM. I honestly know nothing about missiles (I had to look up a picture of the ESSM just to know which one it was), so if I did anything wrong here, or if I do anything wrong in the future with respect to missiles, I'm counting on you and other more knowledgeable members to call me out.
I was considering your comments regarding the War of 1812 equivalent and, on second thought, I agree with you. Actually, one of the harder things in researching and writing that timeline was finding people to be PM since so many early US presidents were from Virginia and the southern states.
And, with regards to the basis of the Maritime Navy's history, I had the same idea. A navy based around protection of Maritime trade interests around the world. In other words, a cruiser and destroyer centric fleet in the WWI-WWII era. For now, I'll just be sticking with the modern navy of the MU, but, when I finish that at some point in the future, I'll probably make some historical ships from that era.
Thanks for your suggestions,
