The F-16's retiring are probably some older A and B models assigned to Air National Guard units. The regular Air force and many Air guard units are still going strong using F-16's. Many times units will have their designation changed which usually means they get a different aircraft. In it's 60 year history, The Vermont Air Guard has gone through many aircraft types. they started with P-47's, then went to Mustangs, F-89 Scorpions, F-102's, EB-57 Canberra's (the last US unit to fly this type) F-4's and then F-16's. The "replacement" for the F-16 is the new F-35 Joint Strike Fighter which won't be online for 10-12 years. Sometimes during force restructuring, one state will lose it's fighters and get a transport mission and another state will have to switch from C-130's to A-10's.. it all depends on what the Pentagon wants.
New England could be it's own airforce....
Vermont: F-16C's
New Hampshire: KC-135's
Maine: KC-135's
Massachusetts: F-15's
Connecticut: A-10's
Rhoad Island: C-130's
If you add in the Air Force Reserve units you get C-5's from Massachusetts
Add in NY and NJ you get 2 more F-16 squadrons, another of C-130's, AF reserve C-5's, KC-10's and a Aerospace Rescue squadron.
Don't mess with the Northeast LOLOLOL
