Combat systems refer to the integrated suite of sensors, weapons, communication devices, and control interfaces on military platforms, such as submarines, ships, or aircraft. These systems work together to detect, track, identify, and engage potential threats in real time. In submarines, combat systems include sonar arrays, torpedo launchers, missile systems, electronic warfare tools, and command-and-control software. Their primary purpose is to provide situational awareness, enable rapid decision-making, and ensure effective defense or offensive operations. Robust cybersecurity measures are essential to protect these systems from hacking, interference, or manipulation, as any compromise could have severe operational and safety consequences.
