What is the primary function of the SPN-43 radar?

The primary function of the SPN-43 radar is to assist with departure approach and marshalling of aircraft. This radar system provides a range of capabilities that are essential during the departure phase of flight operations on naval vessels, such as aircraft carriers. It supports air traffic control duties by tracking aircraft movements on and around the ship, thereby facilitating the safe and efficient management of aircraft as they take off and depart from the carrier.

In addition to its departure capabilities, the SPN-43 radar can integrate with other systems on a carrier to ensure that the necessary data is available for controllers to guide aircraft safely. This is crucial for maintaining operational tempo and safety in a busy flight deck environment.
