Description
The E-6B Mercury is a communications relay and strategic airborne command post aircraft. It provides survivable, reliable, and endurable airborne Nuclear Command, Control, and Communications (NC3) between the president, secretary of defense, and U.S. Strategic Command. Two operational squadrons (“Ironmen” of VQ-3 and “Shadows” of VQ-4) deploy from their main Operating Base at Tinker Air Force Base, Oklahoma, supported by the TACAMO Weapons School and the fleet replacement squadron (the “Roughnecks” of VQ-7). They deploy aircrews to Forward Operating Bases at Travis Air Force Base, California; Offutt Air Force Base, Nebraska; Naval Air Station Patuxent River, Md.; and other locations, as directed.
Background
Boeing derived the E-6A from its commercial 707 to replace the aging EC-130Q in the performance of the Navy's TACAMO mission. TACAMO links the National Command Authority (NCA) with naval ballistic missile forces during times of crisis. The aircraft carries a Very Low Frequency communication system with dual trailing wire antennas. The Navy accepted the first E-6A in August 1989. The E-6B was conceived as a replacement for the Air Force's Airborne Command Post due to the age of the EC-135 fleet. The E-6B modified an E-6A by adding battlestaff positions and other specialized equipment. The E-6B is a dual-mission aircraft capable of fulfilling either the no-fail TACAMO mission or the airborne strategic command post mission and is equipped with an airborne launch control system (ALCS), which is capable of launching U.S. land-based intercontinental ballistic missiles. The Navy accepted the first E-6B aircraft in December 1997 and the E-6B assumed its dual operational mission in October 1998. The E-6 fleet was completely modified to the E-6B configuration in 2003.
