The Developmental Test, Evaluation and Assessments (DTE&A), under the Office of the Under Secretary of War for Research and Engineering (OUSW(R&E)), plays a critical role in ensuring the readiness and effectiveness of the Department of War (DoW) systems and technologies. DTE&A is dedicated to advancing the science of test and evaluation (T&E) to support the development, acquisition, and deployment of cutting-edge defense capabilities. By fostering innovation, collaboration, and rigorous testing methodologies, the agency ensures that U.S. military systems meet the highest standards of performance, reliability, and safety. DTE&A also serves as a central hub for T&E expertise, providing guidance, oversight, and resources to enhance the DoW's ability to address emerging threats and maintain technological superiority.
