What type of radar is used at Naval Air Stations and Marine Corps Air Stations for air traffic control operations?

The correct answer is the AN/FPN-63(V), which is specifically designed for air traffic control operations at Naval Air Stations and Marine Corps Air Stations. This radar system provides precision tracking of aircraft, ensuring safe and efficient movement of air traffic. The AN/FPN-63(V) supports various operational requirements, such as providing situational awareness to air traffic controllers and aiding in the safe landing and takeoff of aircraft.

The other radar systems mentioned serve different purposes or functions. The AN/SPN-43 is primarily used for air traffic control on an aircraft carrier, while the AN/SPN-44 serves as an advanced instrument landing system. As for the Planned Position Indicator (PPI), it is a type of display that shows radar information in a circular layout, typically used for surface radar and not specifically dedicated to air traffic control operations like the AN/FPN-63(V). Thus, the AN/FPN-63(V) stands out for its dedicated application in air traffic control, making it the appropriate choice for the question asked.
