Which sensor is intended to replace the DSP legacy system?

• A. SBIRS
• B. GPS
• C. IRBM
• D. AEGIS

Answer: (A)

The Space-Based Infrared System (SBIRS) is designed to replace the Defense Support Program (DSP) legacy system. SBIRS enhances missile warning capabilities with advanced infrared sensors that can detect and track missile launches, providing timely alerts and improving situational awareness for military operations. This system represents a significant technological advancement over the DSP by incorporating modern satellite technology, which improves detection accuracy, expands coverage, and provides multi-mission capabilities, including missile defense, battle space awareness, and technical intelligence. While GPS (Global Positioning System), IRBM (Intermediate-Range Ballistic Missile), and AEGIS (Advanced Electronic Guidance Integrated Control System) are vital components in military operations, they serve different primary functions. GPS is primarily a navigation system, IRBM refers to a category of missiles, and AEGIS is a naval weapon system. None of these options fulfill the specific role of replacing the DSP in the context of missile warning and infrared surveillance, making SBIRS the correct choice.
