The USA’s E-6 Fleet: Take Charge, And Move Out!
March 29/21: Update Rockwell Collins won a $16.9 million order, which upgrades the E-6B Mercury mission computer from a 32-BIT to a 64-BIT Linux-based operating system, resulting in an increase to capability and reduced threat vulnerabilities. The principle mission of the E-6 Mercury is to connect the national command authority with the US Navy’s nuclear missile force carried aboard at-sea ballistic missile submarines. The E-6 is a militarized version of the commercial 707 civilian airliner and carries a very low frequency communication system with dual trailing wire antennas. Work will take place in Richardson, Texas and is expected to be finished in March 2023.

The USA’s E-6 Mercury (aka. TACAMO, as in TAke Charge And Move Out) “survivable airborne communication system” airplanes support their Navy’s SSBN ballistic missile submarine force and overall strategic forces. With the advent of the new “Tactical Trident” converted Ohio Class special operations subs, their unique capabilities become even more useful. The E-6B version also has a secondary role as a “Looking Glass” Airborne National Command Post, and in recent years they have seen use as communications relay stations over the front lines of combat.
Delivery of the first production E-6 aircraft took place in August 1989, with delivery of the 16th and final airplane coming in May 1992. This is DID’s FOCUS Article concerning the E-6 system, which includes details concerning the capabilities and associated contracts. The latest contracts involve important fleet upgrades, as the Navy tries to drag the jet’s systems into the 21st century.
