OK, kinda confusing question I know, but there is so much expertise on this forum I had to ask. From the 18th's official history (
http://www.eielson.af.mil/units/og/18fs.htm) it says:
<BLOCKQUOTE id=quote><font size=1 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>On January 1, 1982, the squadron moved to Eielson AFB. Here, the 18 TFS mission became that of providing close air support in the A-10 Thunderbolt.
On March 7, 1991, the 18 TFS received its first F-16C, which it still flies today. The squadron then earned its current designation, the 18th Fighter Squadron, on June 1, 1991.<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>
The key word in the blurb above is "On March 7, 1991, the 18 TFS received its <b>first</b> F-16C." The question is did the 18th continue to fly Hawgs after it became the 18 FS in June, or was it only Vipers??
