Simply put, even if there weren’t imagery of the aircraft itself that gives away its type and mission (which there is) the data above pretty much tells us what it was—a US Navy E-6B Mercury. Even the callsign has been used by these aircraft, something that can be found with a quick Google search.

The E-6B is also known by the acronym TACAMO (Take Charge And Move Out) and executes the “Looking Glass” mission, which has to do with facilitating the release of nuclear weapons during a time of war. The aircraft can also work as a command post for the National Command Authority and as a major network relay and communications node in the aftermath of a national disaster.
