Global Command and Control System - Maritime (GCCS-M)
AN/USQ-119E(V

The Global Command and Control System - Maritime (GCCS-M) AN/USQ-119E(V) previously JMCIS, is the Navy's primary fielded Command and Control System. The nomenclature AN/USQ-119(V) and AN/USQ-119A through D refer to older versions of the Navy Tactical Command System Afloat (NTCS-A) and JMCIS.

The objective of the GCCS-M program is to satisfy Fleet C4I requirements through the rapid and efficient development and fielding of C4I capability. GCCS-M enhances the operational commander’s warfighting capability and aids in the decision-making process by receiving, retrieving, and displaying information relative to the current tactical situation. GCCS-M receives, processes, displays, and manages data on the readiness of neutral, friendly, and hostile forces in order to execute the full range of Navy missions (e.g., strategic deterrence, sea control, power projection, etc.) in near-real-time via external communication channels, local area networks (LANs) and direct interfaces with other systems.

The GCCS-M system is comprised of four main variants, Ashore, Afloat, Tactical/Mobile and Multi-Level Security (MLS) that together provide command and control information to warfighters in all naval environments. GCCS-M provides centrally-managed C4I services to the Fleet allowing both United States and allied maritime forces the ability to operate in network-centric warfare operations. GCCS-M is organized to support three different force environments: Afloat, Ashore and Tactical/Mobile. Afloat configurations can be categorized as force-level and unit-level configurations. Ashore configurations of GCCS-M are located in fixed site Fleet and Tactical command centers as well as mobile rapid deploy command centers such as MICFACs, mobile command facilities designed to provide the CJTF commander with similar C4I capabilities when forward-deployed ashore. In order to allow for maximum interoperability among GCCS systems at all sites and activities (Afloat, Ashore and Tactical/Mobile), GCCS-M utilizes common communications media to the maximum extent possible. The Secure Internet Protocol Router Network (SIPRNET), Non-Secure Internet Protocol Router Network (NIPRNET) and the Joint Worldwide Intelligence Communication System (JWICS) provide the necessary Wide Area Network (WAN) connectivity. JMCOMS will provide the WAN connectivity for the Afloat and Tactical/Mobile GCCS-M systems. Operating "system–high" at the Secret and SCI security levels, both networks use the same protocols as the Internet. In addition to the SIPRNET operating at Secret/SCI security levels, GCCS-T supports collaborative planning at the National Command Authority level by providing Top Secret connectivity to a limited number of sites. OPLANS developed at NCA level can then be downgraded to secret for dissemination using SIPRNET.

GCCS-M has been implemented traditionally on high-performance UNIX workstations because, until recently, only these platforms were powerful enough to run GCCS-M software. However, with the exponential increase in processing capability of the Intel PC processor family and the maturity of the Windows NT and JAVA / Web multi-user operating systems, migrating GCCS-M to the PC environment is a very practical and logical decision. Once designed for the PC environment, GCCS-M becomes largely hardware independent, meaning that it uses almost all existing hardware platforms: UNIX, Wintel, Macintosh, etc. GCCS-M intends to incrementally migrate GCCS-M segments to both the Windows NT and JAVA / Web environments.

GCCS has already replaced the Honeywell computers and associated peripheral equipment used by the Worldwide Military Command and Control System (WWMCCS) in those major command centers that had WWMCCS installations. The full implementation of GCCS and GCCS-M will include more sites than the former WWMCCS sites, and in general these installations will include installation of new hardware to existing C4I systems or upgrading the hardware of existing systems to meet IT-21 and DII COE requirements. The key to understanding GCCS and GCCS-M is that they are principally sets of integrated software applications which will operate on DII COE hardware. During the transition from UNIX servers to Windows NT servers these software applications replace older versions and continue to run using most of the same hardware and network infrastructure already in place, allowing for phased introduction of new hardware.
