From January to July 2011, DISA relocated more than 4,500 military and civilian employees and supporting onsite contractors, 700 workstation suites with 11,000 pieces of advanced IT equipment, and 58,000 square feet of lab equipment in accordance with the Base Realignment and Closure legislation of 2005. The relocation to Fort George G. Meade , Md., consolidated DISA headquarters elements that were housed in multiple locations in Arlington and Falls Church, Va. In April 2011, DISA held a ribbon cutting ceremony officially opening the new headquarters complex.
During the relocation DISA maintained its pace of operations and continued to deploy critical warfighting capabilities with no disruption of service and support to its mission partners.
As it enters the second decade of the new century, DISA continues to engineer, develop, maintain, and operate a global net-centric enterprise in direct support to joint and coalition warfighters, national-level leaders, and other mission partners across the full spectrum of operations.
DISA offers the following services to its mission partners.
COMMAND AND CONTROL
Command and Control (C2) systems provide the U.S. military commander with the information to make effective decisions and provide the warfighter the capability to access the information necessary to complete their mission. The C2 portfolio contains the Global Command and Control System - Joint (GCCS-J), Multinational Information Sharing (MNIS), and Joint Planning and Execution Services (JPES).
MNIS – Applications
CENTRIXS is the Combatant Commander's network for coalition warfighting. CENTRIXS is designed to be a global, interoperable, interconnected, inexpensive, and easy-to use system to share and exchange intelligence and operations information through reliable communications connectivity, data manipulation, and automated processes. The CENTRIXS environment is a combination of network and applications services. CENTRIXS provides a secured exchange of intelligence and operational information through reliable communication networks There are 40+ CENTRIXS networks/communities of interest (COIs) providing selected centralized services including: Active Directory/DNS Roots, VoIP, WSUS and Anti-Virus Definitions, and at least 80 countries plus NATO nations participate in the various CENTRIXS networks/COIs.
Pegasus/Griffin is a multinationally-developed, managed and resourced collection of networks and services that provides information sharing among the 5-Eyes national classified (SECRET level) networks and C2 systems. Griffin enables participating nations to plan, implement and execute multinational planning and operations from the strategic to tactical headquarters level. It permits users to share SECRET REL information from their national C2 system workstations.
The Combined Federated Battle Laboratory Network (CFBLNet) is a coalition RDT Gateway to DoD.
DISA's computing services portfolio includes mainframe hosting, application monitoring, and server hosting and virtualization. DISA manages all the partner data, hardware components, software, and labor.
DISA purchases telecommunications and information technology (IT) products and services for the U.S. military using a variety of contract vehicles.
Enterprise Engineering refers to the Global Information Grid (a.k.a. the GIG). DISA plans, designs, constructs, and analyzes the effectiveness of the U.S. military's cyberspace and establishes the technological standards to make the GIG secure and reliable. The enterprise engineering portfolio includes the Joint Communication Simulation System (JCSS), GIG Technical Guidance for Information Technology Standards, and Interoperability Enhancement Process/iSmart (IEP/iSmart).
Enterprise services provided by DISA to its mission partners fall under three categories: Applications, Infrastructure, and Identity and Access Management.
* Global Video Services (GVS)
* DoD Enterprise Email (DEE)
* DoD Enterprise
* Rapid Access Computing Environment (RACE) * Global Content Delivery Service (GCDS) * Enterprise Service Monitoring * Enterprise Messaging * Enterprise Service Bus (ESB) * Data Services Environment (DSE) * Hosting Services * Secure Technology Application eXecution (STAX)
IDENTITY AND ACCESS MANAGEMENT
* DoD Visitor * Enterprise Directory Services (EDS) * Enterprise Attribute Application Forest (EASF) / Identity Synchronization Services (IDSS) * Open Source Attribute-Based Access Control (ABAC)
DISA's Information Assurance services serve the purpose of:
* Making data ubiquitously accessible while simultaneously restricting access * Promoting the safe sharing of information * Preventing attacks by having network protections in place
The Defense Information Systems Network (DISN) is a worldwide-protected telecommunications network that enables the exchange of information in an interoperable and global space, partitioned by security demands, transmission requirements, and geographic needs of targeted end-user communities.
Nowadays, DISA maintains the following network services, to support diverse telecommunication requirements for organizations focused on, but not limited to, the Department of Defense (DoD):
* SBU IP Data (formerly known as NIPRNet ) * Secret IP Data (formerly known as SIPRNet ) * TS/SCI IP Data (formerly known as JWICS ) * Secret Test Defense Data Network packet-switching nodes; Defense Switched Network (DSN) multi-function voice switches; and technical control facilities. At their peak, these systems included more than 100 satellite links.
On June 25, 1991, DCA underwent a major reorganization and was
Defense Information Systems Agency
DISA’s role in DoD information management continued to expand with implementation of several Defense Management Report Decisions (DMRD ), most notably DMRD 918, in September 1992. DMRD 918 created the Defense Information Infrastructure (DII) and directed DISA to manage and consolidate the Services’ and DoD’s information processing centers into 16 mega-centers. During the 1990s, DISA fielded new systems to support the combatant commands. The Global Command and Control System (GCCS) and the Joint Chiefs’ C4I (Command, Control, Communications, Computers, and Intelligence) for the Warrior, and the Defense Message System were among the critical systems. GCCS was developed to replace WWMCCS, which had been in existence since the early 1960s.
With the new century, DISA faced even greater challenges as a DoD service provider. Preserving radio spectrum, information assurance, ensuring interoperability, and establishing secure wireless links were just some of the tasks performed by the agency. Perhaps the most significant achievement of the agency in 2001 was its immediate response in the aftermath of the attacks of Sept. 11, 2001. DISA justified $300 million in supplemental funds to support the Global War on Terrorism by providing critical communications paths and command and control enhancements for warfighters.
In the 18 months between September 2001 and April 2003, DISA

For Operation Iraqi Freedom in 2003, DISA provided 30 times more bandwidth to a 45-percent smaller force than in Operation Desert Storm in 1991. DISA facilitated multiple enhancements to the nation’s preeminent joint command-and-control system and provided a real-time battle space picture.
After the previous consolidation of 194 data-processing centers in the 1990s into 16 computing mega-centers, DISA further reduced the number of mega-centers from 16 to six. Starting in 2003, DISA managed the six-year, $326 million effort to completely modernize presidential communications — the largest such initiative in the 61-year history of the White House Communications Agency. The “Pioneer Program” transformed presidential communications by employing net-centric concepts to put voice, video, and data at the president’s fingertips on an around-the-clock basis.
The Global Information Grid Bandwidth Expansion (GIG-BE) Program was a major DoD net-centric transformational initiative executed by DISA. The $877 million program was the largest DoD information technology transport structure ever built. GIG-BE created a ubiquitous "bandwidth-available" environment to improve national security intelligence, surveillance, reconnaissance, information assurance, and command and control at locations worldwide. On Dec. 20, 2005, the GIG-BE program achieved the milestone of full operational capability at all of the almost 100 Joint Staff-approved sites.

Defense Information Systems Agency
From 2008 through 2010, DISA worked directly with the commander, United States Central Command (USCENTCOM), to design and implement a high-capacity, strategic communication network into an active Theater of Operations, ensuring reliable communications for intra-theater mission partners and to national leadership. Prior to this installation, the
