Mechanical Drive & Transmission Technologies

Objective: Develop technologies which will assist in the enhancement, revitalization, and resurgence of the transmission industrial-base sectors of the United States. This is necessary for several reasons. It is essential that this particular industrial base remains viable, competitive and robust in order to effectively address U.S. Navy, Marine Corps and Department of Defense modernization and surge requirements.

Further, this industrial sector is critical to the national transportation infrastructure and, therefore, needs to remain responsive and competitive to address national interests. In order to achieve our objectives, iMAST needs to be recognized as a national resource.

Since it is the industrial sector that supplies the DoD with mechanical drive transmission components and systems, it is essential that this recognition be derived from both industry and government sectors alike.

DoD, NAVY, AND THE OFFICE OF NAVAL RESEARCH "....establish and demonstrate key manufacturing processes that satisfy military production requirements. Investments in process technology have historically covered the complete manufacturing maturation cycle: invention, development, insertion, and improvement."

iMAST ChartiMAST Program Management
iMAST is managed by the Office of Naval Research and and is part of the Pennsylvania State University's Applied Research Laboratory (ARL)  which is located in State College, Pennsylvania. ARL Penn State is one of four U.S. Navy University-Affiliated Research Centers.

Carrier and Sub Background
The DoD Manufacturing Technology (MANTECH) Program began in the late 1960s. Over the years, the MANTECH Programs for the Army, Navy, Air Force, and Defense Logistics Agency (DLA) have contributed remarkably to the nation's ability to produce superior military weapons systems platforms. The DoD MANTECH Program is managed by the Director, Defense Research and Engineering (DDR&E). The Joint Defense Manufacturing Technology Panel is chartered to identify and integrate requirements, conduct joint program planning, develop joint strategies, and oversee the execution of MANTECH programs.

MANTECH Objectives
Everything, from the development of new manufacturing processes and products to enhanced manufactured manufacturing techniques for the repair and maintenance of current equipment, must be considered to ensure that the Navy and Marine Corps has the best, most reliable, most cost-effective weapons systems possible. Navy MANTECH strives to reduce the cost of advanced weapon systems and the repair, maintenance, and overhaul of fielded systems through improvements in productivity and responsiveness of suppliers and support facilities. Emphasis is placed on the development of technologies that will be implemented in time to make a difference; technology development for its own sake is not pursued.

The primary MANTECH Program objectives are defined as follows:

  • RISK REDUCTION associated with the transition from research and development to implementation on the production floor
  • IMPLEMENTATION of MANTECH efforts in the production of Navy and DoD weapons systems
  • MAXIMUM DISSEMINATION of manufacturing technology to the defense and commercial industrial base, to stimulate industry, and to invest in and implement new manufacturing techniques and equipment

Planning for the Navy MANTECH Program is based on a top-down methodology that begins with the identification of critical acquisition programs and repair requirements. Planning then proceeds through a structured methodology to identify necessary manufacturing and repair technologies and significant risk reduction opportunities. According to the established criteria for project selection, projects must:

  • PROVIDE A SOLUTION to a well-defined Navy need
  • DEVELOP PERVASIVE TECHNOLOGY applicable to multiple weapons systems
  • ENCOMPASS technology development at risk levels beyond those normally assumed by industry
  • PROVIDE timely implementation for the achievement of anticipated benefits
  • PROVIDE economic, performance, and/or safety improvements

The Navy MANTECH Program has many customers. They range from the acquisition system Program Manager, responsible for transitioning major weapons systems from development into production, to the logistics managers at the naval depots and shipyards who are responsible for the repair, overhaul, and remanufacture of major weapons systems. Additional customers of the Navy MANTECH Program include industry, academia, and the other Services.

Naval Systems Commend, Marine Corps Systems Command, Other Services, and Other Agency Participation in the MANTECH Program
Project ideas are generated from various sources within the Naval Systems Commands, Marine Corps Systems Command, and the other Services. Program Executive Officers (PEO), Program Managers (PM), aviation and ground combat vehicle depots, naval shipyards, Office of Naval Research, Army Research Laboratory, and NASA research and development offices are all welcome to give input or solicit support from iMAST.

A MANTECH project is undertaken when it is determined that industry is unwilling or is financially unable to commit private capital to develop a new process or technique and make it available to the military in a timely manner. Projects are expected to result in new, significantly improved, or more economical manufacturing processes.

Efforts are generally broad-based in application and, whenever possible, will result in processes, techniques, materials or equipment, with application to multiple land, sea, and air weapons systems. All potential projects are coordinated with the specific PM whose weapons system is impacted to ensure that critical needs are addressed and to obtain endorsement for implementation.

The critical elements that must be addressed before a task is proposed are:

  • TECHNOLOGICAL INNOVATION can significantly affect the U.S. defense posture through increased productivity. The application of state-of-the-art technologies is vital to the achievement of Navy-Marine Corps requirements. With the commitment to a modern streamlined naval service, the optimum use of advanced technology, investment capital, and labor become necessary in order to reduce production and overhaul costs.
  • POTENTIAL BENEFITS are a major goal of the MANTECH Program because they identify, measure, and evaluate the impact of proposed technology improvements and their contributions to the project goals. All benefits, quantifiable and non-quantifiable, such as cost savings/avoidance, productivity improvement, improved quality, increased reliability, and improved readiness are significant to the project decision process. They directly impact a weapons system's acquisition and operating costs. Therefore, those projects offering substantial benefits are given the highest priority.
  • IMPLEMENTATION is an important criteria in the selection process. It further demonstrates that the technology developed from a selected project will be used to its fullest extent regardless of whether that office/agency has the wherewithal to assist in the funding. This demonstration will assure reviewers at all levels that the project is not just purely a research effort without a specific ending, but will ultimately be used in the production and/or correction of a DoD weapons system. Projects will normally be tied directly to an acquisition program and will show a scheduled plan that describes the implementation transition.
  • LEVERAGING of any potential funding from other sources is a significant issue. Leveraging may be a joint funding from a contractor, a naval depot, a PEO/PM office, another government agency, one of the other services, or other program such as the Small Business Innovative Research (SBIR) program. Leveraging is important because it demonstrates up front that the task technology is needed and that the community feels strong enough about the particular technology that they will support it with their own funding. The combination of funds will then give the R&D dollar more "bang for the buck."

With few exceptions, a stakeholder is a representative of a Navy/DoD acquisition, procurement, or depot organization that is willing to support a MANTECH project and assist in its implementation. There is no requirement to commit funding to a particular project by the supporting stakeholder. However, the stakeholder must be willing to take an active guidance and monitoring role in the project and work through the Navy MANTECH Program Manager to ensure that program objectives are achieved. The stakeholder should also be willing to voice to the Office of Naval Research strong support for continuation of the project if funding reviews threaten continued support of their particular project.

Industry Participation:
iMAST provides assistance to industry in adopting and using appropriate new and advanced manufacturing technologies that are economically viable. Cross-disciplinary research efforts that address manufacturing challenges too complex for single-investor programs allow iMAST efforts to technologically advance these particular industrial sectors with DoD application. The traditional model for industry participation has been for industry to provide all the cash and in-kind support, while the University provides science, engineering, and manufacturing technologies (intellectual property). The innovative method for industry participation is to have industry and the University combine resources with additional amounts of funding coming from federal and/or state resources.


Strategic Vision

reptechlogo.gif (4479 bytes)REPTECH applies appropriate technologies to improve capabilities of the remanufacture and repair community and plays a central role in utilizing emerging technologies to improve the repair process and the affordability of Navy and Marine Corps repair facilities. Repair technology investments are needed to close the gap between the capability of the repair process and the sustainment needs of the weapon system.

The investments will reduce risks to schedule, reduce costs, and increase performance of repaired weapon systems. ARL’s REPTECH Program has been designated the Navy's coordination center for repair technology. The program is located at The Pennsylvania State University’s Applied Research Laboratory (ARL).

Program Administration
REPTECH is part of The Pennsylvania State University’s Applied Research Laboratory (ARL) which is located in State College, Pennsylvania. ARL Penn State is one of four U.S. Navy academic research laboratories in the country.

Program Management
REPTECH is managed by the Office of Naval Research Manufacturing Technology Program. Benefits of the program apply to all systems command within the Navy and the Marine Corps.

REPTECH Management Structure
The REPTECH Working Group chairperson is a representative of the Office of Naval Research Manufacturing Technology Division. The REPTECH Working Group was created to develop a coordinated approach to identify repair requirements for the Navy and Marine Corps and consists of one representative and one alternate from each Naval and Marine Corps SYSCOMs.


Naval Systems Command and Marine Corps Systems Command Participation
Project ideas are generated from various sources within the systems commands. Program Executive Officers (PEOs), Program Managers (PMs), aviation and ground combat vehicle depots, naval shipyards, and the Office of Naval Research are all welcome to input or solicit support from REPTECH.

The tasks of REPTECH are identified and prioritized by the REPTECH Working Group within the strategic themes for sustainment by the Joint Director Laboratories for Manufacturing Science and Technology. Following the theme "Improve manufacturing and remanufacturing methods, strategies, strategies and equipment of maintenance operations," the REPTECH Working Group evaluates, selects, and funds projects that address the top priority issues and thus offers advanced solutions to the most pressing repair technology needs in U.S. Naval shipyards and depots.

Process Description:

  • Collect REPTECH issues from variety of sources
  • SYSCOMs perform initial screening and database entry of new issues
  • Brief issues to the REPTECH Working Group semiannually
  • Review higher level requirements and match to candidate projects (e.g. Navy Strategic Investment Plan, JDL MS&T thrusts)
  • Approval of projects for funding

Issue Submission Process

Issue Submission Process


  • Apply new emerging technologies to improve  the capabilities of the repair community
  • Improve repair processes and the affordability  of repair facilities
  • Execute Science & Technology (S&T) projects which directly affect depot level maintenance
  • Communicate by all means available
  • Reduce duplication of effort in REPTECH related R&D
  • Leverage program funding with funds from other programs and agencies

Stakeholders are required for all REPTECH projects. With few exceptions, a stakeholder is a representative of a Navy or Marine Corps acquisition, procurement, depot, or shipyard organization that is willing to support a REPTECH project and assist in its implementation. There is no requirement to commit funding to a particular project by the supporting stakeholder. However, the stakeholder must be willing to take an active guidance and monitoring role in the project and work through the REPTECH program manager to ensure that project objectives are achieved. The stakeholder should also be willing to voice to the Office of Naval Research strong support for continuation of the project if funding reviews threaten support of their particular project.

Industry Participation
Where feasible, technology transfer is completed through a commercial vendor. Commercial partners are found in order to take project results to commercial production. As a result of this arrangement, an infusion of cash and/or in-kind support leverages REPTECH dollars. Additional industry matching amounts of funding may be secured through state and/or federal sources which act to further leverage Navy funding.
