I very much agree with Evicted here. We've not fixed the carrier (So far no call to do so, which is fine), ERA is still a wasted revision in everyone's minds, and here we are developing a MRLS. Seriously? Fixing ERA might have made our tanks resistant to that silly autoloader (Even though I don't support ERA). We've not, as he pointed out, done anything to our steel coffins on the high seas, though they desperately need it.
Let's shoot big. If we don't get this jet fighter this turn, with the credit and using the revision, then we have clear incentive to back up our choices and push for it next turn. Whittle has been pushing this jet concept for most of a decade at this point. The technology isn't unknown. We're developing it for ourselves. Yes, it's gaining some improvements, but we expect the improvements to have issues. When they have issues, we then go ahead and fix them in a revision, and a design, and a second revision, whatever it takes to give ourselves a huge leap in technology over the heads of the Cannalans. We can't hurt ourselves any more than discarding our strengths and we can't doom ourselves any better than undershooting and thus having nothing to fix (If we go for the weak fighter, and get it at an OKish level, we won't be making a better one in a revision, and will thus be stuck with an OK fighter that the ADHD portion might just go "OK it's fine let's get moar rockets guys" or whatever floatplane bad idea is floating around now.
