TACAMO

Last updated October 04, 2024

TACAMO (Take Charge And Move Out) is a United States military system of survivable communications links designed to be used in nuclear warfare to maintain communications between the decision-makers (the National Command Authority) and the triad of strategic nuclear weapon delivery systems. Its primary mission is serving as a signals relay, where it receives orders from a command plane such as Operation Looking Glass, and verifies and retransmits their Emergency Action Messages (EAMs) to US strategic forces. As it is a dedicated communications post, it features the ability to communicate on virtually every radio frequency band from very low frequency (VLF) up through super high frequency (SHF) using a variety of modulations, encryptions and networks, minimizing the likelihood an emergency message will be jammed by an enemy. This airborne communications capability largely replaced the land-based extremely low frequency (ELF) broadcast sites which became vulnerable to nuclear strike.

Components

The current TACAMO system comprises several components. The main part is the airborne portion, the U.S. Navy's Strategic Communications Wing One (STRATCOMWING 1), a U.S. Strategic Command (USSTRATCOM) organization based at Tinker Air Force Base, Oklahoma. STRATCOMWING 1 consists of three fleet air reconnaissance squadrons (VQ-3, VQ-4, and VQ-7) equipped with Boeing IDS E-6B Mercury TACAMO aircraft. As well as the main operating base at Tinker, there are a west coast alert base at Travis AFB, California, and an east coast alert base at NAS Patuxent River, Maryland.

History

The acronym was coined in 1961^{[ citation needed ]} and the first aircraft modified for TACAMO testing was a Lockheed KC-130 Hercules which in 1962 was fitted with a VLF transmitter and trailing wire antenna to test communications with the fleet ballistic missile submarines (see communication with submarines).

The Naval Air Development Center developed the required technique of "stalling" the trailing antenna to achieve the long vertical antenna needed.^[1] The VLF system is currently known as VERDIN (VERy low frequency Digital Information Network).^[2] The program was expanded in 1966 using modified C-130s designated Lockheed EC-130G/Q carrying a VLF system built by Collins Radio Company.

The first two squadrons were established in 1968: VQ-4 initially operated from Naval Air Station Patuxent River, Maryland and VQ-3 was initially formed at NAS Barbers Point, Hawaii before moving to Naval Air Station Agana, Guam, but later returned to NAS Barbers Point. The system known as TACAMO (from "take charge and move out") has been operationally deployed in 1969. TACAMO consisted of twelve Lockheed EC-130Q aircraft equipped with VLF transmitters using long trailing wire antennas.^[1] VLF system was repeatedly upgraded to improve signal strength.

By 1971, TACAMO IV incorporated a 200 kW transmitter and dual antenna. Actual transmission power and capabilities remain classified. Airborne ELF was tested but considered infeasible. The aircraft were upgraded to the E-6 Mercury beginning in 1990, and the E-6A was upgraded to the dual-role E-6B from 1998. With the introduction of the E-6, the Navy also stood up a Fleet Replacement Squadron (FRS), VQ-7, to provide initial training for new Naval Aviators, Naval Flight Officers and enlisted Naval Aircrewmen, and recurrent training for former TACAMO crewmembers returning to aircraft for second and third tours.

The E-6 aircraft is based on the Boeing 707. The wings were redesigned to meet new wing-loading characteristics; the tail was redesigned after a catastrophic failure of the vertical stabilizer during flight tests. The cockpit was copied from the Boeing 737NG commercial airliner, and the landing gear was modified to handle the added weight. Larger fuel tanks were installed and the fuselage was extensively modified to accommodate the 31 antennas, including the trailing wire antenna and reel assembly.^[1] After the upgrade to the E-6B, the TACAMO aircraft—with the addition of an Airborne Launch Control System (ALCS)—took over the EC-135 Looking Glass mission formerly conducted by the USAF 55th Wing at Offutt AFB, Nebraska.

In early 1991 TACAMO planes, which have been in the air nonstop for nearly three decades, were transferred to "interim ground alert" and their flights continued on a "random basis" off the US east and west coasts.^[3]

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.

Communication with submarines is a field within military communications that presents technical challenges and requires specialized technology. Because radio waves do not travel well through good electrical conductors like salt water, submerged submarines are cut off from radio communication with their command authorities at ordinary radio frequencies. Submarines can surface and raise an antenna above the sea level, or float a tethered buoy carrying an antenna, then use ordinary radio transmissions; however, this makes them vulnerable to detection by anti-submarine warfare forces.

In the United States military's strategic nuclear weapon nuclear command and control (NC2) system, an Emergency Action Message (EAM) is a preformatted message that directs nuclear-capable forces to execute specific Major Attack Options (MAOs) or Limited Attack Options (LAOs) in a nuclear war. They are the military commands that the US military chain of command would use to launch a nuclear strike. Individual countries or specific regions may be included or withheld in the EAM, as specified in the Single Integrated Operational Plan (SIOP). The SIOP was updated annually until February 2003, when it was replaced by Operations Plan (OPLAN) 8044. Since July 2012, the US nuclear war plan has been OPLAN 8010-12, Strategic Deterrence and Force Employment.

The Boeing EC-135 is a retired family of command and control aircraft derived from the Boeing C-135 Stratolifter. During the Cold War, the EC-135 was best known for being modified to perform the Looking Glass mission where one EC-135 was always airborne 24 hours a day to serve as flying command post for the Strategic Air Command in the event of nuclear war. Various other EC-135 aircraft sat on airborne and ground alert throughout the Cold War, with the last EC-135C being retired in 1998. The EC-135N variant served as the tracking aircraft for the Apollo program.

Looking Glass is the historic code name for an airborne command and control center operated by the United States. In more recent years it has been more officially referred to as the ABNCP. It provides command and control of U.S. nuclear forces in the event that ground-based command centers have been destroyed or otherwise rendered inoperable. In such an event, the general officer aboard the Looking Glass serves as the Airborne Emergency Action Officer (AEAO) and by law assumes the authority of the National Command Authority and could command execution of nuclear attacks. The AEAO is supported by a battle staff of approximately 20 people, with another dozen responsible for the operation of the aircraft systems. The name Looking Glass, which is another name for a mirror, was chosen for the Airborne Command Post because the mission operates in parallel with the underground command post at Offutt Air Force Base.

The Airborne Launch Control System (ALCS) provides a survivable launch capability for the United States Air Force's LGM-30G Minuteman III intercontinental ballistic missile (ICBM) force. The ALCS is operated by airborne missileers from Air Force Global Strike Command's (AFGSC) 625th Strategic Operations Squadron (STOS) and United States Strategic Command (USSTRATCOM). The system is located on board the United States Navy's E-6B Mercury, which serves as USSTRATCOM's "Looking Glass" Airborne Command Post (ABNCP). The ALCS crew is integrated into the ABNCP battle staff and is on alert around the clock.

The Lockheed E-XX is a planned United States Navy aircraft based on the EC-130J and intended to replace the Boeing E-6 Mercury in the TACAMO role, communicating with US nuclear ballistic missile submarines. The current E-6 aircraft were built in the late 1980s, and while they are expected to fly into the 2030s, the underlying platform is aging and support costs are increasing. Because of this, in 2020, the Navy began a program to develop a new platform. This program will take several years to complete, and the E-6 will continue to fulfill the role in the meantime.
