I keep wondering about the 1,763 number of F35As that the USAF "Needs".
If as seems likely, the USAF wants to take the A10 out of service, closing down the whole logistical and training chain to make the required savings, implicitly thus reducing the USAF headcount, there will be no need, personnel, or indeed funding, to replace these A10 squadrons with more expensive F35A squadrons, that must have an impact on the unit costs...
