From Wikipedia
The Boeing E-6 Mercury is an airborne command post and communications relay based on the Boeing 707-300. The original E-6A manufactured by Boeing's defense division entered service with the United States Navy in July 1989, replacing the EC-130Q. This platform, now modified to the E-6B standard, conveys instructions from the National Command Authority to fleet ballistic missile submarines, a mission known as TACAMO.
