What is IFF used for?

Explanation:
IFF is an identification system used to distinguish friend from foe and to share identity with cooperating units. When challenged by radar or a control system, a friendly transponder replies with a coded identification, helping controllers and units know who is where. This capability reduces the chance of misidentification and enables coordinated action among allies. It isn’t about transmitting weather data, nor is it limited to navigation, and it isn’t used only by civilian vessels.
