TEA: Transportation Engineering Agency.


The mission of TEA is to improve the global deployability and sustainment of U.S. armed forces by providing the Department of Defense with transportation engineering, policy guidance, research, and analytical expertise to support the National Military Strategy.

Director's Vision

As the premier Department of Defense deployment engineering and analysis center, TEA employs state-of-the-art computational and analytical tools as well as the most advanced information system technologies to satisfy the warfighter's total force projection needs.

Today's National Military Strategy is built on the military's ability to rapidly deploy, project and sustain armed forces anywhere in the world. These force projection goals are constantly evolving and becoming ever more demanding. TEA supports these requirements with timely and accurate deployment and surface distribution-related analyses and transportation engineering solutions.

TEA's highly motivated team includes civil, mechanical and computer engineers, operations research analysts, transportation specialists, computer specialists, engineering and computer technicians, and a diverse and highly skilled support staff. Customer satisfaction is the number one priority.

TEA also serves as the surface component of the U.S. Transportation Command Joint Distribution Process Analysis Center, providing analytical capability and engineering support to USTRANSCOM, its components, and the Joint Deployment and Distribution Enterprise community.

TEA plays a key role in ensuring that U.S. military forces can respond successfully to any requirement anywhere in the world.

Organizational Structure

TEA is divided into three divisions: Deployability Division, the Office of Special Assistant for Transportation Engineering (SATE), and the Systems Integration Division.

Deployability Division

The Deployability Division provides transportation engineering, research and analytical expertise to improve the deployability of U.S. Armed Forces.

The Division evaluates the transportability characteristics of military materiel to ensure equipment moves safely and efficiently by current or future transportation assets. The Division conducts transportation engineering analyses of multi-modal nodes and networks that support power projection.


The Division also assesses force deployability with complete, time-phased, origin-to-destination analysis of force closure. These assessments consider limitations and capabilities of the Defense Transportation System, transportability of individual equipment items and CONUS and OCONUS infrastructure. The Deployability Division helps shape the military by using sophisticated modeling, simulation, engineering, and analysis, to provide deployability solutions.

Deployability Analysis

Deployability Analysis supports Combatant Commanders by using sophisticated modeling and simulation tools to assess transportation plans, including throughput, usage for nodes and routes, theater lift assets required and used, potential bottlenecks, constraints, and Reception, Staging, Onward movement and Integration.

DPA assists deployment planners in development and refinement of the Time Phased Force Deployment Data during deliberate planning, crisis action planning and exercises. DPA has dedicated teams that support each of the major warfighting Combatant Commanders. Deployability Engineering

Deployability Engineering is an SDDC core competency. It provides transportation engineering and deployability analysis to maximize DOD force projection capabilities. The key processes of Deployability Engineering are Transportability Engineering, Force Modernization, Deployability Analysis and Transportation Infrastructure Engineering.

Transportability Engineering

At the very foundation of force deployability is equipment transportability. Transportability Engineers work closely with requirements writers and equipment developers, including defense contractors, program managers and other government organizations throughout the acquisition life cycle, to influence the design of systems in favor of efficient transportability.

TEA evaluates every aspect of an item's transportability characteristics, including: weight, dimensions, lifting and tie-down provisions, interface with required transportation assets and infrastructure, and structural integrity. This mission is accomplished through both advanced virtual simulations and live testing. These efforts ensure that equipment design facilitates rapid force deployment.

Force Modernization

The Force Modernization Team focuses on the design and concepts for employment of current and future transportation assets that will deploy our military equipment and forces. To maximize the military utility of these assets, The Force Modernization team is involved from concept development, to fabrication, to recapitalization.

This integrated involvement involves recommending deck strengths and layouts for the large, medium speed roll on roll off ships, evaluating deployment scenarios of the Interim Brigade Combat Teams, and providing deployability expertise to the developers of the Future Combat System. The Force Modernization team's efforts continue to optimize systems for rapid deployment.

Office of the SATE and Programs for National Defense

The Office of the SATE traces its roots back to July 1955, the Chief of Staff of Logistics directed the Chief of Transportation to provide technical assistance to the services and military installations. The Chief of Transportation established the SATE to provide consultation services to Army installations worldwide and coordinate all activities relating to transportation efficiency and safety.


The SATE staff advises the SATE and commander, SDDC, on transportation engineering policy matters. SATE also manages and executes the DOD Highways, Railroads, and Ports for National Defense Programs, and develops defense transportation engineering policy in concert with USTRANSCOM and the Office of the Secretary of Defense.

Highways for National Defense

The HND Program identifies the minimum public highway infrastructure that DOD needs to fulfill its mission; then integrates the public highway needs into civil policies, plans, and programs. HND also ensures the defense readiness capability of public highway infrastructure and establishes policy on how DOD uses the public highway system.

The SATE works with the military services, Major Commands, installations, ports, U.S. Department of Transportation, U.S. Federal Highway Administration, the American Association of State Highway and Transportation Officials, state transportation departments, and Congress to accomplish these goals.

DOD's public highway needs are identified in the Strategic Highway Network. STRAHNET is a system of about 61,000 miles of highways, including the Interstate System. An additional 2,000 miles of STRAHNET Connectors link important military installations and ports. Together, STRAHNET and the Connectors define the total minimum public highway network necessary to support Defense deployment needs.

In addition, HND establishes policy and guidance on how the DOD uses the public highway system, assisting the military in highway movement problems, working to ensure highway safety, and helping guarantee the highways' readiness condition for deployment.

Railroads for National Defense

The RND Program ensures the readiness capability of the national railroad network to support defense deployment and peacetime needs. The Program integrates defense rail needs into civil-sector planning, affecting the nation's railroad system.

The RND Program, in conjunction with the US Federal Railroad Administration, established the Strategic Rail Corridor Network to ensure DOD's minimum rail needs are identified and coordinated with appropriate transportation authorities. STRACNET is an interconnected and continuous rail line network consisting of over 38,000 miles of track serving over 170 defense installations.

RND works with state DOTs, the American Association of Railroads, the Surface Transportation Board, the American Railway Engineering and Maintenance of Way Association, the Railway Industrial Clearance Association, the FRA, and individual railroad companies to protect this railroad infrastructure.

Ports for National Defense

The PND Program's primary goal is to ensure the identification, adequacy, and responsiveness of defense-important CONUS port infrastructure. Team members accomplish this by visiting ports, analyzing strategic planning documents, providing input into the deliberate planning process, coordinating workload requirements with Combatant Commanders and SDDC, and working with governmental agencies such as the Maritime Administration.


TEA conducts transportation engineering analysis of CONUS and OCONUS seaports, selected Army installations, airports, airfields, and the highway and rail networks that support Power Projection Platforms. Much of the work of the Transportation Infrastructure contributes to the Highways, Ports and Railroads for National Defense Programs.

Joint Infrastructure Working Group

The JIWG is a working group of the Power Projection Council of Colonels. Their mission is to analyze joint infrastructure required to support deployment of legacy, interim and objective Army forces. The JIWG reviews existing infrastructure at Army Power Projection Platforms and associated Airports of Embarkation, and makes estimates of additional deployment infrastructure needed to support an Interim Brigade Combat Team.

The Intelligent Road/Rail Information Server

IRRIS retrieves data about U.S. highways, bridges, traffic, military installations, and seaports. It accesses multiple military databases at once including strategic seaports, installations, National Bridge Inventory, National Railway Network and National Highway Planning Network.

IRRIS tracks items like road characteristics, bridge locations, video logs of primary routes, feature attribute data, and aerial photo and satellite imagery. The system also provides real time travel information about traffic congestion, weather, road closures, and construction detours.

Intermodal Systems

The Intermodal Systems Program at TEA influences deployment doctrine, planning, and available deployment infrastructure. We give input to both the Army and the Joint community on transportation doctrine to create new ways of doing business. The Intermodal Systems Program also contributes to special projects related to intermodal deployment with analytical and engineering support.

Systems Integration

Systems Integration Division is responsible for supporting the TEA's Global Defense Transportation Engineering efforts by developing and managing deployment, distribution and transportation modeling, simulation and analysis tools; managing acquisition and distribution of authoritative transportation data; and managing TEA's Information Technology infrastructure data.

The Division develops and manages tools to support Deployability Engineering and Analysis. These state-of-the-art tools model the interaction of the infrastructure and transports systems with the transportability characteristics of the force. They include tools for analyzing movement requirements, CONUS and theater networks, and seaports.

Systems integration also performs data acquisition and analysis in support of TEA and external customers. The team works with Air Mobility Command, SDDC G-6 and Chief Information Officer, to manage and administer TEA's IT infrastructure including local and wide-area networks, workstations, servers, deployable equipment, websites and communications.


Transportability and Deployability

Transportability is the inherent capability of an item to be moved efficiently by towing, self-propulsion, or carrier, using existing equipment or equipment that is planned for the movement of the item via rail, highway, water and air. To meet this capability, TEA takes full consideration of available and projected transportation assets, mobility plans and schedules, and the impact of system equipment and support items on the strategic mobility of operating military forces.

Deployability is the capability of an entire force (personnel and cargo) to be moved intra-CONUS, inter-theater (strategically), and intra-theater (tactically) to support a military operation.
