I'd actually really like to vote for Plan Chaeronea, because
@Chaeronea did a good job laying out a plan and justifying it. But I think ToC Weapons is actually important and want to start seriously researching weapons tech as soon as feasible, because arming our ships with obsolete weapons is... problematic. And the only other plan that includes ToC weapons is the one I'm already voting for: Void Stalker's plan.
Okay, I begin to understand.
I do agree with the issue involving the
Oberths and the impracticality of doing better than them on a small hull because it means we have to pack an excessive number of techs into a flying-bomb hull. Hopefully Oneiros will tinker with that so that it is actually possible to design viable science vessels, but that won't be happening yet. I don't consider Klingon research important either, though we shouldn't neglect it entirely, because maintaining peace with Klingons requires
understanding Klingons. When "the Wall came down in space" at Khitomer, the Federation didn't understand the Klingons very well, in my opinion.
Where I sharply differ from you is on two issues.
One catch is, I don't consider starting the Ambassador project in 2310 desirable, because I want the Ambassadors to be
qualitatively better ships than the
Excelsiors, not just bigger ones. Another five years' research might very well make the difference between a slightly bigger
Excelsior and a ship that can really hold its own into the mid-century. We're still using some first-generation techs in the design process, and I don't want that. Given that it takes something in the neighborhood of ten years to design and prototype a ship, waiting until 2315 to start the Ambassador doesn't present problems if we want the class to come into service starting in the 2320s, which seems like a reasonable goal and is in line with canon.
Another is that I think we need to prioritize weapons research. We are already a bit behind the curve, I think, and we only just got our weapons team. We should use it; it will make it a lot easier for us to build competitive ships in the future. I mean, you're basically talking about designing an
Ambassador that will be armed with 23rd century weapons, and I don't think that's a good idea.
