You got some tough ones there, Dr. Chicken! But I'm game to give it a try... here goes:
35 of this aircraft were modified by SAC in 1959 with extensive communications equipment to act as airborne relays from ground command centers to the ICBM fields and bomber bases in times of war...what aircraft was it?
The 'original' KC-135R (this was well before the 'R' designation identified reengined KC-135s).
What is the ORIGIN of the name TACAMO?
OK, now I knew
what TACAMO stood for, now you want to know how it got its name?!?

My silly wild a** guess: the Navy wanted a survivable system that could communicate to the 'boomers' when the sh*t hit the fan, to 'take charge' of the situation and 'move out at a moment's notice.
USAF E-3 AWACS are being upgraded and are now sporting funny little cheek fairings and chin fairings. What are they for?
My silly wild a** guess again: SLAR (side-looking airborne radar) pods on the fuselage sides, and possibly LLLTV (low-light-level TV) on the chin fairings just like the BUFFS.
What is the USAF system/aircraft for the detection, analysis, and jamming of enemy communications?
Dunno. I'm guessing 'Cobra Ball'.
When the new Boeing E-6 TACAMO aircraft entered service, it was called the E-6 Hermes. Now the Navy calls them the E-6 Mercury. Got a guess on why the name got changed?
Hermes and Mercury are one and the same mythological god; the 'messenger of the gods'. Hermes being the Greek name, and Mercury the Roman name. Wouldn't be surprised if they changed the name so as not to get confused with the similar-named disease of herpes... my silly wild-a**ed contribution to this tale
