Yeah, it's about requirements. The Ukraine war has shown that fast-iterating MVPs are better in many battlefield situations. The saying that militaries end up preparing for the prior war instead of the next, comes to mind.

True, but I think the US requirements are indeed different. Ukraine must repel invading forces in their own country -> lowish range, mass produced, not necessarily precision strike.

US want to project power far away from its shores -> long range, precision strike, long loitering time.
