The Boeing E-6 Mercury is a specialized 707-derived aircraft family used for survivable airborne communications relay and strategic command-post missions. The E-6A entered Navy service for the TACAMO mission, while E-6B modifications added command-post equipment and a dual communications/airborne-command role; the family remains an important example of a civil transport adapted for national command-and-control continuity.
