It’s all for show. The Ukrainians will fly a token number of daytime only CAP sorties over Kyiv from NATO airbases with the F-16s. The pilots they have available for the F-16 training (which is a year behind schedule) are far too few in number to do anything meaningful in contested airspace, and that is assuming they’ll have enough pilots making it through training to be capable of flying any sorties at all.
What I read says it takes an American pilot up to 9 months to train in the F-16. Good Grief! I was hoping the war would be over before then!
