 However, the original weapons and munitions R&D mission remained at Picatinny after being renamed the U.S. Army Armament Research and Development Center (ARDC).In 1986, a further reorganization of all of the Army's R&D centers caused ARDC to become ARDEC.This name was retained when the group was transferred again to the Tank-automotive and Armament Command (TACOM) in 1994, and again to the Research, Development and Engineering Command (RDECOM) in 2003.
