The story
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.
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.
