I spent 3 1/2 years in Vietnam / Thailand. I flew on the AC-47 about 4 or 5 times, until we finally got the AC-130 (2nd version of the gunship) . Usually, it was night flights that took us over the trail in search of trucks, etc....and in support of Fire bases. In my final year there (71-72) I was assigned to the 18th SOS (Special Operations Squadron) flying out of Phan Rang and NKP on the 3rd version of the Gunship, now a AC-119. Depending on which one you were on -- AC-119G (Shadow) or the AC-119K (Stinger) of which the AC-119K models had JATO, and were armed differently. We had night scopes, ECM, FLIR, Side-Looking Radar, M61 Vulcan Cannons, + 20MM, etc. Please refer to my avatar to see my Squadron patch...."Vengeance by Night" Boy, what a ride that was.
