CP TANGO / Command Post TANGO
Command Post (CP) TANGO (Theater Air Naval Ground Operations) is the primary warfighting headquarters for the Korean theater. For the Eighth US Army command staff, being able to communicate using Video Teleconferencing (VTC) in a timely manner from separate strategic locations was critical to the prompt execution of EUSA operations, as well as the operation of military units scattered throughout US Forces Korea. The northern hub, based at CP TANGO controled and distributed VTC slides and briefings and would then forward them down to the southern hub, based out of Camp Walker, which provided CP OSCAR with the VTC. With up to 15 VTC sites on the Korean peninsula, it was vital that the operators have the VTC equipment operational for every scheduled and unscheduled brief that might arise.
The Joint Staff, DISA, and DA directed PM DCATS Product Manager DSCS Terminals to replace the 4 existing AN/TSC-86 terminals located at Landstuhl, Germany; Fort Detrick, Maryland; Torii Station, Okinawa, Japan; and Command Post TANGO, Republic of Korea. The new terminal would use existing HT/MT equipment and components, which eliminated costs for establishing a logistics system to support the terminal. The system was built and had successfully completed acceptance, and DISA Certification testing at TYAD. The AN/TSC-86B terminal was a fixed configuration and installed at CP TANGO, Republic of Korea.
US military communicators in Korea had been looking at the battlespace in a new way. Colonel Gregory Edwards, J6 of the United States Forces Korea said in early 2007 that communicators in Korea had shifted their focus from data, such as reports and forms, and even from concepts such as information, systems, and capabilities and now instead were focusing on effects-based operations, meaning they're planning, executing, and assessing military activities with an eye the effects produced rather than merely attacking targets or simply dealing with objectives.
A case in point was the array of technology bristling in the new Combatant Commander's Operations Center at Command Post TANGO (Theater Air Naval Ground Operations), thanks to a project completed in July 2006 by the Command Center Upgrades/Special Projects Office of the Project Manager, Defense Communications and Army Transmission Systems of Fort Monmouth, New Jersey, part of the Army's Program Executive Office, Enterprise Information Systems. The new CCOC was successfully used during the annual Ulchi Focus Lens exercise with the Republic of Korea, which was conducted from 21 August to 1 September 2006.
The CCOC included a high-resolution command information display system, the ability to conduct briefings within the bridge up to the Secret-US Only level, connectivity to a one gigabit backbone, a video teleconferencing capability, a multi-classification capability in accessing the Secret Internet Protocol Router Network/Combined Enterprise Regional Information Exchange System-Korea and Non-secure Internet Protocol Router Network at 5 workstations that allows users to control multiple computers from the "hot seats."
"The new bridge will enable improved parallel planning for the staff during a very congested 24 hour planning, decision and execution cycle," said Edwards. "The commander's intent is that his subordinate commanders will be using their C4I (command, control, communications, computers and intelligence) systems to collaboratively plan and execute various missions they've been assigned either as a supporting or supported command. Due to C4I enhancement provided via this battle cab, our command is being transformed to literally think beyond systems and is effectively integrating capabilities into the operational framework of our forces."
The FASTBACK system that was replaced in Korea is reflective of the typical legacy mw systems used by the US Army to support worldwide long haul communication requirements. The FASTBACK system (seven individual links) provided a secure reliable means of transmitting bulk data collected along the Demilitarized Zone to command groups located in the southern part of the country. The equipment (i.e., radios and multiplexers) supporting the FASTBACK system had been in operation for over fifteen years, utilizing technology that was over twenty years old. The FASTBACK system consisted of an AN/FRC-162 radio and AN/FCC-97 multiplexer. In the late 1990s it was replaced by a high speed (155 Mbps) SONET digital microwave radio that utilize the digital data multiplexer (DDM)-2000 OC3 multiplexer. The Digital Microwave Upgrade DMU Phase I is a good example of what occurs when the link bandwidth is increased (8 DS1s to 84 DS1s (three 45 Mbps DS3)) with high speed SONET digital microwave and interface requirements to existing older, low speed mw technology. The Yongsan to Madison, Osan to Madison, and Camp Humphreys to Madison FASTBACK links were replaced during Phase I with the Harris MegaStar 2000 SONET radio. The remaining FASTBACK mw links between Madison and Kamaksan, Kangwhado, and Songnam, and Kamaksan and Yawolsan, were replaced during DMU Phase III. In conjunction with the DMU, the digital patch and access systems (DPAS) at Yongsan, Osan, and Camp Humphreys were upgraded to support up to three DS3s each.
