The Defense Acquisition System is a structured process used by the U.S. Department of Defense to acquire goods and services necessary for national defense. This system ensures that military needs are met efficiently and effectively, balancing cost, schedule, and performance. It involves multiple phases, including planning, development, and production, to ensure that the final products meet the required specifications. Key components of the Defense Acquisition System include program management, contracting, and testing. These elements work together to facilitate the procurement of advanced technologies and equipment, such as weapons systems and support services, ultimately enhancing the operational capabilities of the U.S. Armed Forces.
