Our History
In 2001, the Department of Defense streamlined support for test and training customers by merging the engineering and technical support management of several western test and training ranges into one contract, known as J-Tech. On Feb. 1, 2002, EG&G (now known as AECOM) and Raytheon Technical Services Company (RTSC) joined forces to create JT3. The company helps its U.S. Air Force and Navy customers improve effectiveness while generating substantial cost savings and exceptional performance.
