USA wants to subsidize the f16..the way its doing it now is by suppling a single standaradized version called block 70..every one will get this version. the order will be by USA dod and it will act as conduit for further providing it to allies.
so basically USA has just ordered 90 f16s at cost of 4.9b dollars and will now distribute it to its allies, 66 will got to tiawan
this approach has dropped the f16 price from 100 million dollars to less than 60m apiece.
now i guess training and weapons will be a separate cost. but this has made f16 a very attractive option among all the countries that were leaning to buy Gripen/typhoon/rafale or some neutral companies who wanted to buy russian equipment
