JADC2 is to ensure continuity of commander's intent— instead, JADC2 was to be exercised in late August or early September 2020. IBCS —Integrated Air and Missile Defense Battle Command System— is undergoing a Limited user test in August-September 2020 in preparation for a Milestone C acquisition decision. IBCS is a critical building block for JADC2; the ABMS test is a separate project. Thirty-three different hardware platforms, some using 5G, 70 industry teams, and 65 government teams participated in this ABMS Onramp, the first week in September 2020.
