JT3 provides engineering and technical support to four of the western test ranges for the U.S. Air Force and Navy under the Joint Range Technical Services Contract, better known as J-Tech.

The company is a joint venture of Raytheon and URS (formerly EG&G) and is supported by 10 teammate companies. Together we develop and maintain realistic integrated test and training environments. We prepare our nation's war-fighting aircraft, weapons systems, and air crews for today's missions and tomorrow's global challenges.
