The E-6B Mercury is the US Navy's airborne link to its ballistic missile submarines — the mission is called TACAMO: Take Charge And Move Out. It can relay orders from the National Command Authority, stand in as STRATCOM's airborne command post, and even remotely control Minuteman missiles from the air. Sixteen were built, and they exist so the chain of command survives the worst day imaginable.

Fun fact

With aerial refueling an E-6B can stay airborne for up to 72 hours — and the E-6 was the final new derivative of the Boeing 707 ever built.

How to spot one

A gleaming white 707 with almost no windows and pods on the wingtips, based at Tinker AFB, Oklahoma. If one orbits the same patch of sky for hours, it is on station doing its job.

Sounds like
Four CFM56s on a 707 airframe — a classic heavy-jet departure sound, flying a mission most people never think about

One might be overhead right now.

Bogey turns the TACAMO from a dot in the sky into a card in your logbook.
