Army Test & Evaluation Command


On Nov. 18, 1998, the vice chief of staff of the Army approved consolidation of developmental and operational testing. That decision led to the redesignation on Oct. 1, 1999 of the Operational Test and Evaluation Command to Army Test and Evaluation Command.

Central to the consolidation was ATEC assuming overall responsibility for all Army developmental and operational testing. The Test and Evaluation command became a major subordinate command of ATEC and was redesignated the U.S. Army Developmental Test Command, with DTC headquarters remaining at Aberdeen Proving Ground, Maryland. Also, the Test and Experimentation Command was redesignated the U.S. Army Operational Test Command, with OTC headquarters remaining at Fort Hood, Texas. The third ATEC subordinate command that was redesignated encompassed both the Operational Evaluation Command and the Evaluation Analysis Center, which were combined to form the new U.S. Army Evaluation Center, completing the earlier decision to move developmental and operational evaluation into a single, integrated command.

When working at ATEC, employees become involved with people of many disciplines and receive “hands on” experience with the most sophisticated and advanced technology in the world.

Our staff designs and uses highly accurate and precise instrumentation to test sophisticated military systems under controlled conditions at testing facilities located around the country. Newly assigned personnel become involved in important projects, working closely with a wide range of specialists from other Government agencies and industries.

Today, ATEC is organized into developmental testing, operational testing and evaluation.
