The original E-6A manufactured by Boeing Integrated Defense Systems entered service with the U.S. Navy in July 1989, replacing the EC-130Q. It conveyed instructions from the National Command Authority to fleet ballistic missile submarines, a mission known as TACAMO (“Take Charge and Move Out”). The E-6B model deployed in October 1998 kept this role but added further command post capabilities and control of land-based missiles and nuclear-armed bombers. The E-6B replaced Air Force EC-135C’s in the “Looking Glass” role, providing command and control of U.S. nuclear forces should ground-based control become inoperable.
