Space-Based Infrared System

Target entity: Space-Based Infrared System
Context triple: [Air Force Space Command, oversawProgram, Space-Based Infrared System]

• A. AN/MPQ-53 radar
  The AN/MPQ-53 is a multifunction, phased-array fire control radar used to detect, track, and guide interceptors against aircraft and missile threats in the Patriot air defense system.
• B. Raytheon Sentinel R1
  The Raytheon Sentinel R1 is a British airborne battlefield and ground surveillance aircraft equipped with advanced radar and sensor systems to provide real-time intelligence and reconnaissance support.
• C. AN/TPY-2 radar
  The AN/TPY-2 radar is a high-resolution, X-band, phased-array missile defense radar used for detecting, tracking, and discriminating ballistic missile threats.
• D. Patriot missile system
  The Patriot missile system is a long-range, all-altitude, air-defense system designed to detect, track, and intercept incoming aircraft, missiles, and drones, widely used by the U.S. and allied militaries.
• E. Aegis radar components
  Aegis radar components are advanced naval radar and combat system elements designed to detect, track, and guide weapons against multiple airborne and missile threats as part of the Aegis Combat System.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
