> What you need in a big war against a worthy adversary is the ability to quickly innovate and iterate on designs, and having a single design that try to do everything is about the worst option available for that. That's what you might think with a certain naive look at WWII. All indications are that in any modern conflict between countries with the capability to manufacture this kind of hardware, it'll be all over before there's time to design or build anything. You win with what you have when the war breaks out, or you lose. Assuming you're lucky enough for it to not go nuclear, since any country like that can also build lots of nuclear weapons and delivery systems, and they pretty much all have already.
