 The NAC is the focal point for automotive collaborative research and development within the U.S. Army's Tank-automotive and Armaments Command (TACOM).  This collaborative software development program falls under the federal government's Dual Use Science & Technology Program, which is designed to share the benefits of technology between the military and the private sector.  PTC, acting as the prime contractor, will be working with a team comprised of General Dynamics Land Systems, Lockheed Martin Advanced Technology Laboratories, IITRI/AB Technologies, EDS, and Fakespace Systems to fulfill the U.S. Army's goals of fielding its Objective Force by 2008.
 
 "Our established relationship with PTC is strengthened as they continue to deliver high-quality, affordable solutions, which help us meet our requirement of operating digitally by the year 2002," said Dennis Wend, director of the National Automotive Center.  "PTC's Web-centric technologies are the next step that will lead to the creation of an enterprise-level and commercially-offered Simulation Based Acquisition (SBA) Environment.  Interoperable, open- standards-based, and commercially supported technologies such as Windchill will dramatically lower the costs associated with the development of next- generation military and commercial automotive products."
 
 Under the agreement, the NAC will use PTC's Windchill solutions as its Integrated Data Environment (IDE) across TACOM programs to support the Army's vision of reducing the cost of developing next-generation transport and weapons systems.  In addition, R&D efforts will focus on providing enhanced, immersive environment capabilities, Web-centric project management solutions, and the development and deployment of a program manager IDE toolkit.
 
 C. Richard Harrison, president and CEO at PTC said, "PTC has a strong history of partnership with the Army and other federal agencies to provide leadership for next-generation design and development systems.  This agreement will accelerate the introduction of software functionality that will provide benefits throughout the industry. We look forward to continuing to build upon the relationship with TACOM and the NAC."
