This thing already seems set up messy. Halting so late into competition cause of cost concern or perhaps cause Air Force faced impossible choice of goin with Boeing then now it’s gonna be cheaper than f-22.
Last time Northrop bailed voluntarily out of a program you know what happened aka A-12 paper plane
As far as is known publicly, there were no changes to the requirements or submissions, and indeed it is hard to imagine that a six month pause would allow for either. At most all that changed was who the preferred vendor was, and even then there were rumors that the Boeing submission was favored going back a year. NGs public statement was that they wanted to focus on FA-XX. Quellish stated that they did not like conditions of the contract intended to prevent vendor lock. Either way, it seems like the pause had nothing to do with it - in fact IIRC, NG dropped before the pause, so the two are unrelated.
