What is the guidance system for the Sea Sparrow?

The Sea Sparrow missile utilizes a semi-active guidance system, which means that it relies on external illumination to guide it to the target. In the case of the Sea Sparrow, this typically involves a radar system that illuminates the target and provides the necessary guidance updates. The missile itself homes in on the reflected radar signals rather than generating its own targeting data.

Semi-active guidance is effective because it combines the advantages of radar guidance with the capability of the missile to home in on reflected energy, allowing for precision targeting during its flight. This system requires a radar source to keep the missile on the correct path, which aligns well with naval operations where ship-based radar can effectively track and illuminate targets.

Understanding the characteristics of the Sea Sparrow's guidance system is essential for operational awareness and effective use during combat scenarios.
