Following their removal from active USAF service in England in 1965, twenty-nine ex-USAF F-101As (serial numbers 54-1445, 1449, 1451, 1452, 1453, 1454, 1455, 1457, 1459, 1460, 1461, 1462, 1463, 1464, 1466, 1468, 1469, 1470, 1472, 1473, 1475, 1476, 1477, 1479, 1481, 1482, 1484, and 1485, plus two others whose serials I don't know) were modified by Lockheed Aircraft Service Company of Ontario, California to serve as unarmed reconnaissance aircraft for use by the Air National Guard. The armament and radar were removed and new nose cones housing cameras were installed. The camera fit included a pallet of cameras mounted aft of the front fuselage bulkhead, and a new nose housing a forward-facing camera. The nose cone slid forward on rails to allow technicians to maintain the cameras and load film. Large hinged panels allowed access to the pallet and avionics bay to the rear. These aircraft were redesignated RF-101G. As compared to the RF-101A dedicated photo-reconnaissance version of the F-101A, the RF-101G had a shorter and broader nose.
The first RF-101Gs went to the Kentucky Air National Guard (165th TRS/123rd TRW) in July of 1965, replacing the RB-57B. The 165th TRS was involved in the military buildup surrounding the 1968 *Pueblo* crisis, although it did not actually deploy to Korea. The RF-101G also went to the 154th TRS/189th TFG of the Arkansas ANG. In 1971, there was a rationalization of Air National Guard units, with all the RF-101Gs being sent to the Arkansas ANG. The Kentucky ANG transferred its RF-101Gs to the Arkansas ANG and transitioned to the RF-101H (an equivalent conversion of the F-101C). In 1972, the Arkansas ANG traded in its RF-101Gs for RF-101Cs that had recently been withdrawn from active-duty USAF service.
