What are Air Defence Systems?
Air defence systems are advanced military networks that detect, track, intercept, and neutralise aerial threats such as fighter aircraft, cruise missiles, ballistic missiles, and unmanned aerial vehicles (UAVs). They integrate surveillance radars, fire-control radars, interceptor missiles, and command-and-control platforms into comprehensive Integrated Air Defence Systems (IADS). According to global defence market estimates, the air defence market was valued at USD 46.55 billion in 2024 and is expected to reach USD 81.92 billion by 2035, expanding at a CAGR of 5.27% from 2025 to 2035. This growth is being driven by rising hypersonic missile threats, expanding drone warfare, and ongoing missile modernisation programmes worldwide. Air defence systems are a networked shield of sensors, weapons and command centres designed to protect the airspace by neutralizing airborne threats utilised by enemies. These systems operate to safeguard military and civilian assets against targets such as airplanes, drones, cruise missiles and tactical ballistic missiles. Air defence systems can at times target low-Earth orbit missiles and outer atmospheric threats, depending on the range.
