terminals are installed on most bombers, aircraft, UAVs, and tankers, allowing for the incorporation of most air defense systems. Integrated Air and Missile Defense Battle Command System The Integrated Air and Missile Defense Battle Command System (IBCS) is an unified command and control network developed by the U.S. Army. It is designed to integrate data relay between weapon launchers, radars, and the operators, which allows air-defense units to fire interceptors with information being relayed among radars. The advantage of such a system is it can increase the area an air unit can defend and reduce interceptor spending by ensuring than no other air defense unit would engage the same target. The IBCS will be able to integrate with air defense networks of foreign military as the global C2BMC system. IBCS engagement stations will integrate raw data from multiple sensors and process it into a single air picture, and choose elect different weapons and launcher locations depending on the detected threat instead of being limited to particular unit capabilities. The IBCS system is intended to be operational in 2019; between 2016 and 2017, implementation of IBCS had to be put on hold due to software issues with the system. In 2021, F-35 sensor data were linked via airborne gateway to ground-based IBCS, to conduct a simulated Army fires exercise, for future Joint All-Domain Command and Control (JADC2). History The problem was first studied during the last year of the Second World War. The only countermeasure against the V-2 missile that could be devised was a massive barrage of anti-aircraft guns. Even if the missile's trajectory were accurately calculated, the guns would still have a small probability of destroying it before impact with the ground. Also, the shells fired by the guns would have caused more damage than the actual missile when they fell back to the ground. Plans for an operational test began anyway, but the idea was rendered moot when the V-2 launching sites in the Netherlands were captured. In the 1950s and 1960s, missile defense meant defense against strategic (usually nuclear-armed) missiles. The technology mostly centered around detecting offensive launch events and tracking inbound ballistic missiles, but with limited ability to actually defend against the missile. The Soviet Union achieved the first nonnuclear intercept of a ballistic missile warhead by a missile at the Sary Shagan antiballistic missile defense test range on 4 March 1961. Nicknamed the "Griffon" missile
