The first three planes are from teh 4477th TES based at Tonopah Test range from 1981 to 1987. This unit is the one that flew captured and purchased MiG’s against USAF and USN units in the aggressor role. It was all very secret and only recently has the full story of this unit become public, probably because it was disbanded after the end of the Cold War. Interestingly, there is now rumors of it being reestablished since Russia is acting much like the old Soviet Union.
Anyway, the first plane is a T-38A from November 1986, and painted in three browns.
Next is a MiG-23MS from 1981. This is an ex-Egyptian plane and painted in a couple of greys. This aircraft is actually quite dangerous to fly as it is not one can throw around the sky and will come apart if to0 much maneuvering is done.
The third plane from this unit is a Shenyang F-7II that was one of a dozen bought new in 1987 to replace the ex-Indonesian A.F. MiG-21Fs. These planes had a very short life span as the unit stopped flying in 1988 and was disbanded in 1990. Most if not all of the Soviet based equipment used has been farmed out to museums or put into storage.
The next two options are from the 4450th TES, also based at Tonopah. These planes were part of the F-117A program.
The A-7D was used to maintain pilot proficiency and for chase duties until there were enough F-117s available. This one is from 1988 and is the boss bird.
The other is a T-38A from 1987 that was also used for pilot proficiency and chase.
The final option is an E-8C based with the 116th ACW at Warner Robins AFB in 2006.
