Yes, this is one of the correct places to ask questions about the Starfire Historical Mod.
One of the features of this mod is to recreate peacetime economies for democracies like the USA. The USA is the most extreme case as historically they had very little military spending until just before the war. So I've cut their IC production and then it kicks back in with the event/tech you mentioned. You'll find these country specific techs in "Land Doctrines" (an out of the way place to put them - eventually I intend to move them to the end of the Land Doctrine list to get them further out of the way since they can't be researched).
