👉 Columbia missiles, also known as SCM-55s or SM-3 interceptors, are advanced missile defense systems designed to intercept and destroy ballistic missiles in their midcourse or terminal phases. Developed by Lockheed Martin, these missiles utilize a solid-propellant rocket motor and a terminal phase radar for tracking and guidance. They are capable of engaging targets at altitudes up to 35 kilometers, making them effective against intercontinental ballistic missiles (ICBMs) and other high-threat threats. The SM-3 missile's design allows it to operate independently of a command center, enhancing its survivability and effectiveness in defending against missile attacks.
