Aberdeen Proving Ground

Mission St​atement
"Our wo​rkforce has more than 21,000 military, civilian and contractor employees responsible for numerous technical achievements across a broad spectrum of military capabilities. If a Soldier uses a piece of technology for protection, intelligence, to shoot, to move or to communicate chances are it was developed, tested, and fielded by an APG ​organization.​"

History and General Information

Aberdeen Proving Ground (APG) was established in 1917 on the shores of Chesapeake Bay in Harford County, Maryland, to provide the nation a site where Army materiel could be tested. At the same time, the Edgewood Arsenal was established nearby to provide a site for the development, production, and testing of chemical warfare materiel. The two installations were officially joined as Aberdeen Proving Ground in 1971. The base covers 72,500 acres and includes 200 buildings, the Phillips Army Airfield, and the Weide Army Aviation Support Facility. APG is also host to the National Guard and U.S. Army Reserve operations and training. The installation hosts 11 major commands and has more than 90 tenant organizations.1

As a "Home of Innovation," more than 21,000 military, civilian, and contractual employees at APG are responsible for numerous technical achievements in military intelligence, medical research, engineering, communications, and computer technology. APG is an economic driver and technology resource for the region. APG provides facilities to perform research, development, testing, and evaluation of Army materiel. The installation also supports a wide variety of training, including health promotion and preventive medicine, chemical and biological defense, chemical casualty care, and chemical demilitarization.2

APG is a Department of Defense Center of Excellence for C5ISR (Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance); Chemical, Biological, Radiological, Nuclear, and Explosives (CBRNE), Research and Development; Test and Evaluation; Public Health; and Personnel Security Investigation.

The 2005 Base Realignment and Closure Commission action created a shift in tenants. Among the changes was a consolidation of C5ISR from other installations and relocation to APG.

Compatib​le Use Organizations, Programs, and Resources

For more information on how Aberdeen Proving Ground (APG) works with surrounding communities to build strong and mutually beneficial relationships, you can explore compatible use organizations, programs, and resources.

Community Resources to Promote Compatibility

Military installations and their host communities have strong and mutually beneficial relationships. They rely on and support one another in terms of jobs, housing, schools, recreation, infrastructure, and social services. Communication, coordination, and partnerships that support compatible community development can create mutually beneficial results to ensure support for warfighters and their families, military operations, and continued community growth and economic development.

Aberdeen Proving Ground Joint Land Use Study


A Compatible Use Study, formerly referred to as a Joint Land Use Study, represents a community-driven, cooperative, and strategic planning process to protect and preserve military readiness and defense capabilities while supporting continued community growth and economic development. The study is based upon technical information the military service provides to describe current military operations. The compatibility analysis results in a series of recommended actions included in an implementation strategy.

The Aberdeen Proving Ground Joint Land Use Study (APG JLUS) was prepared under contract with the Chesapeake Science and Security Corridor, a part of Harford County Office of Economic Development, with financial support from the Office of Local Defense Community Cooperation (formerly known as Office of Economic Adjustment), Department of Defense. The APG JLUS, completed in November 2015, details the study efforts and implementation recommendations. It was a collaborative effort among APG and the adjacent communities of Harford, Cecil, and Kent Counties, as well as the cities of Aberdeen and Havre de Grace.

The APG JLUS includes recommended strategies to address topics such as communication and coordination, frequency spectrum impedance/interference, housing availability, land use, roadway capacity, safety, marine environments/climate adaptation, noise, safety, vertical obstructions, and water quality/quantity. Explanations of compatibility factors can be found here. The recommended strategies were the result of a collaborative planning process representing a coordinated approach to compatibility planning developed with the support of stakeholders involved throughout the process. The Joint Land Use Study Playbook includes JLUS background materials and an Executive Summary Brochure.

Related Studies


The APG Noise Management Plan includes impacts of mission operations on local communities and was a key data set and point of reference that helped form the compatibility assessments including in the APG JLUS. As part of the Noise Management Plan, APG published A Citizens's Guide to Noise Management to summarize APG's Installation Compatible Use Zone Study.

Upon completion of the APG JLUS several Implementation Studies were developed to support the findings and recommendations included in the JLUS.

The Edgewood Small Area Study was an implementation study completed for the Edgewood area to provide more detailed planning guidance for a specific geographic area adjacent to the installation to promote compatible community development and support the installation.

Prepared for Harford County and the APG-CSSC Joint Land use Study Committee, Planning for Coastal Resiliency in the Northern Chesapeake Bay serves as a foundation for a regional strategy to address sea level rise and shoreline stabilization in the area. The study identifies associated risks of sea level rise and provides guidance for incorporation of resilience measures into infrastructure planning activities that will help APG and surrounding communities build a greater margin of safety as it pertains to sea level rise.

Local Comprehensive Planning


Counties and municipalities develop comprehensive plans to provide a long-term vision for future growth and development of the area. Comprehensive plans typically include maps showing proposed future land use and anticipated transportation and community facilities, and emphasize sustainability as well as protection of environmental features, historical, and cultural resources.

While comprehensive plans in Maryland do not require a military element, many plans for jurisdictions around APG include references to the installation and consider potential influences on the community. APG is referenced in the following comprehensive plans:

  • City of Aberdeen (2011)
    • The effects of BRAC and APG are referenced throughout the Comprehensive Plan. As noted in the document, the Plan will provide the basis for growth for [our] future population as it relates to BRAC and will address the existing needs of our citizens and businesses.
    • APG is cited as a key economic driver for the Aberdeen area and its impact is described throughout the Municipal Growth Element Planning Area #16 (Aberdeen).
    • APG is designated as its own Planning Area (#17) within the Municipal Growth Element. The Comprehensive Plan recognizes that this particular Planning Area is not necessarily adapted for immediate growth but is in close enough proximity to be considered in the Plan, especially considering the impact APG has on the community.
    • The Transportation Element considers the infrastructure needs and impacts of APG and considers future growth of the installation in its traffic analyses and recommendations.
  • HarfordNEXT (2016)
  • City of Havre de Grace (2004)
    • APG is recognized in the Municipal Growth Element as a consideration for future growth in respect to the influence of BRAC and the expansion of facilities and personnel at APG and on the housing demand in Havre de Grace.
  • Cecil County (2010)

The following is an additional comprehensive plan for an area immediately surrounding APG:


Economic Resources to Promote Compatibility

A jurisdiction's economic development office and support organizations offer a variety of resources that help the community seek out economic growth opportunities and strengthen existing businesses. These resources are particularly valuable for defense communities who are continually looking for ways to attract new business, retain a skilled workforce, and provide resources and opportunities for military families relocating to the area.


APG Workforce and Economic Impact


APG generates more than 23,698 direct, indirect, and induced jobs as a result of its operations in Aberdeen and the surrounding region.3​​ This includes the military, civilian, and contractor employees responsible for carrying out the installation's mission and the employment opportunities generated by local spending on goods and services by the workforce. For a breakdown of employment type by installation, refer to the installation's economic impact analysis sheet.

According to the FY 2021 Economic Impact An​alysis of Maryland's Military Installations, prepared by the Maryland Department of Commerce, the annual economic output for APG (the sum of direct, indirect, and induced impacts) is $4.01M, with a total employee compensation of $2.3B. APG is Harford County's largest employer and among the largest in the state of Maryland

Army Alliance, Inc.


The Army Alliance, Inc. was founded in 1999 as a non-profit organization. The objective of the organization is to support the programs and organizations of APG, including enhancing and maintaining the region's economic vitality. The Army Alliance overview includes an organization description, purpose, significant past achievements, and current initiatives.

The Army Alliance, in partnership with the Chesapeake Science & Security Corridor (CSSC), created a resource booklet on how to do business with APG, its six Centers of Excellence, and 90+ tenant organizations. Alphabet Suit contains explanations of military and government acronyms, organizational names, terminology, and general guidance on visiting APG.

A YouTube video series called The ABC's of APG - Intro to APG is in progress. The Alliance is developing the informational video series to explain the missions and programs of APG, while also providing history and other background information.


Chesapeake Science & Security Corridor


The Chesapeake Science & Security Corridor (CSSC) brings together multiple jurisdictions in three states (MD, DE, PA) to work together to ensure a high quality of life for those who live and work in defense communities. The APG CSSC Regional Office is part of the Harford County Office of Economic Development. It serves as a clearinghouse and event coordination hub for regional activities related to APG including Base Realignment and Closure (BRAC)-related information. The Association of Defense Communities named CSSC a Great American Defense Community in 2018.


Economic Development in Harford County


Harford County's Economic Development Office works to strengthen business development throughout the county and offers a variety of programs and services to foster business retention, growth, and new investment for businesses of all sizes. The office partners with many organizations to foster economic stability and growth, including APG, the Harford Chamber of Commerce, the Maryland Department of Commerce, Small Business Development Center-Northern Region, and the APG Tech Transfer Office.


Office of Small Business Programs Aberdeen Proving Ground


The Office of Small Business Programs Aberdeen Proving Ground is an industry resource for companies seeking to do business with mission partners from the Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance, and Reconnaissance (C5ISR) and other APG tenant activities. The office has an Industry eKiosk that allows registered users to easily search for companies and provides additional resources for working and partnering with the Army.

Susquehanna Workforce Network


Susquehanna Workforce Network is a private nonprofit corporation that represents an affiliation of more than 50 local businesses, organizations, and agencies that collaboratively execute a system of education, training, employment, and outreach programs in Cecil and Harford Counties. The Network contributes to advancing and expanding the competitiveness of the region, in addition to creating jobs and growth in the local economy. This includes supporting the APG workforce. Operations and programming are funded through federal, state, local, and private resources.

Regional Transportation Organization


The Baltimore Metropolitan Council (BMC) is the regional Metropolitan Planning Organization responsible for coordinating planning activities and investment decisions related to surface transportation assets (roads, bridges, transit assets, pedestrian facilities, and bicycle facilities). Roadway congestion, construction, and transportation planning are regional concerns that impact local communities and access to APG, potentially affecting employees, service members, and the mission. Communication between the military installation and the BMC is necessary to ensure an adequate regional transportation infrastructure that supports continued military operations.
