If the aircraft were to be named after their first flight date, then it would have made more sense to just name them after the year of that date: A=2006F35, B=2

If the aircraft were to be named after their first flight date, then it would have made more sense to just name them after the year of that date: A=2006F35, B=2008F35, C=2010F35 or for -6-, -8-, & -10- whether prefixed or postfixed. But they are not and C has been deemed to having further meaning. It makes the military look dysfunctional to not have any consistency and to be careless with naming.
