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.

That's actually Standard, not ESSM

The ESSM (or RIM-162) is the second to last missile on this sheet (on the left). Using this very same sheet you can also distinguish each USN-built missile.

5 comments on your frigate:
- there is something funky going on with your text
- design wise, she looks quite ok, quite good even
- however, the drawing looks quite dated. I think you'll agree with me that the old drawings on the archive are quite visible to be surpassed by better sources, better drawing programs and if I may say so, better artists. using the latest parts and giving a small update toe the shading of this design (and possibly even add an underwater hull) would improve this drawing immensely
- the SMART-L radar and the Herakles radar.... I have never seen them together and I am not certain they should be. Herakles especially is designed to be the single radar on board vessels, doing fire control and surveillance all on it's own. it is designed for the guidance of ASTER.
the SMART-L on the other hand is an long range surveillance radar. there is no reason not have them together (they do not interfere with each others frequency bands) but they might be doing quite a lot of each others job, which sounds costly.
- last but not least, you have sea wolf on board, which you have no guidance equipment for. ASTER is active, while Sea Wolf is IIRC semi-active, so it cannot be guided by the same type of radar. I also think ASTER 15 kind of replaced sea wolf anyways, so why do you have it on board?
