A test F-4C (designated as NF-4C) at the massive platform of Edwards AFB (CA). In these day's countless F-4s in all variants could be found here. Check the large pitot tube of this old Phantom. The 6512th Test Squadron under command of the 6510th Test Wing operated at that time with A/YA-7D, VA-7F, A-7K, NA/OA-37B, NF-4C/D/E, YF-4E, NRF-4C, F-15A/B/C/D/E, F-111A, F-111D, FB-111A (later, F-111G), UH-1N, O-2A, T-37B, T-38A, AT-38B, T-38C, and UV-18 (haha!) in all kinds of test missions. The F-4s were eventally pashed out in 1992. The squadron is currently known as 4445th Flight Test Squadron.
