Fictional livery for the Lockheed Martin KC-130, based closely on the livery of No. 216 Sqn, RAF's Lockheed TriStar aerial refueling aircraft.
I spent quite a while getting as many details as I could accurate on this livery, though fictional it should make for an authentic looking RAF tanker for your missions.
