Back in 1986, the B-1B flight test program was using F-4s , F-111s, and sometimes a civilian T-38 for acceptance/test flights. Workload constraints and increasing costs in using these aircraft was also becoming a problem. A dedicated B-1B chase aircraft was needed and the F-106 was chosen. In March 1986, Det 15 Contract Management Division (AFSC) to support the B-1B program contracted by Rockwell Inc. at plant 42 at Palmdale CA was started. Eight F-106s would be assigned between 10 Oct 86 and 06 July 90. The first F-106, "B" model 57-2513 from Kelly AFB TX, arrived at Palmdale on 18 Oct 86. Last to depart was F-106A 59-0061 on 06 July 90 to AMARC. Jerry Roth, a F-106 crew chief, designed the distinctive tail flash -- a real eye-catcher! Chase flights were also flown out of Tinker AFB OK, the B-1B depot.
