At what range does the SPQ-9B radar primarily operate for air targets?

The SPQ-9B radar is designed for surface and air target detection, with a particular emphasis on providing effective support for naval operations by detecting airborne threats. The primary operating range for air targets is approximately 80 nautical miles. This range allows the radar to effectively track and identify a wide variety of aerial threats, contributing to situational awareness and the overall defense capabilities of naval vessels equipped with this system.

In addition to its effective tracking range, the SPQ-9B radar is characterized by its capability to maintain target tracks even in cluttered environments, which is essential for operational effectiveness during combat scenarios. The 80 nautical mile range strikes a balance between engaging distant targets while providing timely data for naval decision-makers.

Other ranges listed do not accurately represent the primary operational capabilities of the SPQ-9B radar for air targets; these ranges either exceed the radar's effective operational parameters or fall short of its designed capabilities.
