JT4 Timeline


In 1999/2000, the Department of Defense streamlined support for test and training customers by merging the engineering and technical support for several western test and training ranges into one contract, known as the Joint Range Technical Services (J-Tech) Contract. In 2001, JT3 competed for and won the J-Tech Contract. In 2015, the J-Tech Contract was restructured and re-competed as J-Tech II. JT3 updated and reinvented itself as JT4 and, again, competed for and won the J-Tech II Contract.


JT4 helps the U.S. Air Force and Navy customers improve effectiveness while generating substantial cost savings and exceptional performance. Since our founding, our workforce of more than 2,000 employees and teammates has supported thousands of test and training missions with a commitment to integrity, innovation, and excellence.
