ACAT (Acquisition Category)

ACAT, or Acquisition Category, is a classification system used by the U.S. Department of Defense to categorize and manage defense acquisition programs based on their size, complexity, and potential impact. It helps determine the necessary level of oversight, resources, and planning required for developing and acquiring defense systems, such as ships, aircraft, or software. Essentially, ACAT ensures that programs are properly managed according to their significance, with higher categories requiring more rigorous oversight and funding. This system enhances organization and accountability in military procurement.
