The Defense Information Systems Agency (DISA) provides global information and technology assistance through online services (“net-centric”) for the military and the Department of Defense. DISA helps the United States military forces connect to one another no matter where they are located, pull information needed for their missions, and receive accurate and protected information on any threats they may face. The Agency focuses on delivery of information speed, operational effectiveness and efficiency, and sharing information,. Its primary aim is to provide secure and reliable communications networks, computers, software, databases, applications and other products needed for the processing and transport needs of the Department of Defense.


The Defense Information Systems Agency (DISA) was originally named the Defense Communications Agency (DCA) and founded in Washington DC in 1960. Also in 1960 DISA moved to Arlington, Virginia and integrated the Air Force Office of Commercial Communications Management, the White House Signal Agency, and the Department of Defense Damage Assessment Center into their agency. During this time, DISA also established six regional communications control centers and two area centers for operational control of the DCA.
During the 1970s, the DCA incorporated the Minimum Essential Emergency Communications Network and the Military Satellite Communications Systems Office; it also became responsible for engineering and operating the Worldwide Military Command and Control System. In the 1980s DCA absorbed the Joint Tactical Command, Control, and Communications Agency and also formed the Joint Interoperability Test Command to provide interoperability compliance testing and certification. DCA was renamed the Defense Information Systems Agency in 1991 to reflect its role in providing total information systems management for the Department of Defense and in 1997 the Joint Spectrum Center and the Defense Technical Information Center was absorbed by DISA.
Base Realignment and Closure’s 2005 decision consolidated DISA and moved its headquarters to Fort Meade, Maryland; however actual relocation of all personnel who choose to remain does not need to be completed until 2010.


DISA History


What it Does  

The Defense Information Systems Agency is a combat support agency of the Department of Defense responsible for planning, developing, fielding, operating and supporting command, control, communications, and information systems. DISA works to make information virtual and on-demand through its core services. These services include enterprise services, contracts, spectrum services, network services, voice services, information assurance, computing services, and testing.
Under Services and Capabilities, DISA has many programs, including an acquisition planning and execution tool to enable customers to develop, save, route for review and/or print using a single web browser such as Internet Explorer or Netscape. Another tool is the Defense Message System used to record organizational messaging by the Department of Defense; it provides multimedia messaging, directory and security services. Additionally, DISA operates the Global Information Grid Enterprise Services Engineering directorate that plans, engineers, acquires, and integrates secure global “net-centric” solutions to satisfy needs during wartime. Enterprise services also include NETWARS, a network wartime simulation program for the Joint Chiefs of Staff to use for modeling military communication systems; by simulating communications effects of formed or planned networks, NETWARS helps to quantify risks and identify deficiencies.
Under Contracts, DISA works to provide information on obtaining a contract to work with and for DISA and the Department of Defense in communication and technical services. Here you can find the contracts guide, contracts available, and who is already contracting with DISA. Some of the contracts already established are with DISN Global Solutions with a $3 billion ceiling for nine years, Europe Enterprise Wireless Characteristics with a $114 million ceiling for two years, and with Inmarsat Airtime and Equipment with a $200 million ceiling for ten years.
Spectrum Services include the Joint Spectrum Center and the Strategic Planning Office that lead in engineering expertise and services dedicated to ensuing effective use of the electromagnetic spectrum. An electromagnetic spectrum is the range of all possible electromagnetic radiation and extends below the frequencies of modern radio. They develop and provide support for spectrum planning, and work to manage the use of comprehensive and integrated spectrum planning and its access. The Strategic Planning Office is also responsible for dealing with national spectrum issues, international spectrum coordination and for pursuing emerging spectrum efficiency technologies to new Product acquisitions by the Department of Defense.
DISA also serves as the single senior manager for all Defense Information System Network activities. Its Network Services therefore include support for the products and services offered by DISA and they provide technical assistance for the Department of Defense long-haul networks. Combined with these are the voice services that deal with providing private-line telephone networks, mobile networks, and secure voice and voice-conferencing capabilities for the President, Secretary of Defense, Joint Chiefs of Staff, and other agencies.
DISA also operates the Center for Computing Services under Director Alfred Rivera. The Center provides computing services for a variety of information systems to the Department of Defense. They provide the Department with personnel, payroll, logistics, accounting, and medical records processing.
The testing component of DISA is called the Joint Interoperability Test Command and conducts testing of national security systems and information technology systems hardware, software, and components. Tests work on looking at product and system development, conformance, interoperability, operation and validity.

Where Does the Money Go  

Contract Award Dispute
In 2002 DISA was involved in a contractual controversy in which they awarded work on the Defense Research and Engineering Network, a high-speed linkage for more than 5,000 scientists at universities and Defense Department locations. The initial award went to Global Crossing, a telecommunications firm. However, DISA withdrew the award a few weeks later due to protests by losing bidders who argued that Global Crossing did not meet specific security requirements. After 10 months of controversy and debate among the five vendors vying for the position, DISA re-awarded the 10-year, $450 million contract to WorldCom Inc.

Defense Information Systems Agency
Pollett, Carroll
Previous Director

President George W. Bush nominated U.S. Army Lieutenant General Carroll F. Pollett in September 2008 to be director of the Defense Information System Agency (DISA) in the Department of Defense after the Senate refused to confirm Bush’s first choice for the job, Rear Admiral Elizabeth Hight, because her husband, retired Air Force Gen. Gary Salisbury, was a vice-president of business development and sales at defense contractor Northrop Grumman.

In addition to leading DISA, Pollett was commander of the Joint Task Force—Global Network Operations, overseeing the operation and defense of the Global Information Grid enterprise that supports the military’s war-fighting, intelligence and business missions, until that unit was deactivated on September 7, 2010.
Pollett was commissioned through the Infantry Officer Candidate School. He earned a Bachelor of Science degree from Georgia Southern College and holds master’s degrees in business administration from Central Michigan University and in national resource strategy from National Defense University.
Some of Pollett’s previous assignments and commands include serving as commander of the 123rd Signal Battalion, 3d Infantry Division (Mechanized); action officer in the Office of the Deputy Chief of Staff for Operations and Plans in Washington, DC; director of Joint and Army Current Operations, Office of the Director of Information Systems for Command, Control, Communications and Computer Systems; commander/deputy chief of staff, G-6, 3rd Signal Brigade, III Corps, at Fort Hood, Texas; division chief of Command, Control, Communications and Computer Systems, J-6, The Joint Staff; and commander/principal director of operations for the DISA (2002-2003).
His more high-ranking commands were serving as commanding general of the 5th Signal Command and deputy chief of staff of the U.S. Army Europe and Seventh Army in Germany; commanding general of the U.S. Army Network Enterprise Technology Command/9th Signal Command (NETCOM) at Fort Huachuca in Arizona from 2005 to 2008. As NETCOM commanding general, Pollett initiated the creation of a memorial wall to honor soldiers and civilians who died while supporting signal operations during the wars in Afghanistan and Iraq. Known as the Cove of Remembrance, it is located inside the entrance of Greely Hall at Fort Huachuca.
He served briefly as chief of staff of Strategic Command at Offutt Air Force Base in Nebraska, just prior to being nominated to head DISA.
Pollett and his wife, Dayna, have two sons, Derek and Brian.
