F-106A-100-CO, 58-0793 assigned to the 5th FIS, 25th AD, based at Minot AFB and seen being prepped for flyout to Mohave to become a QF-106A 'drone' in March 1993.
This was a couple of week long process to pull the jet out of storage and make it flight ready.
After it became a QF-106, the vertical tail and wingtips were painted red covering up the beautiful 'ADC' tail marks except for the rudder. Since they would have to pull the rudder and re-balance it if they painted it, they just masked it off when they painted the tail.
The drone ramp was always a beehive of activity on my trips to MASDC/ AMARC!
