I have been running an advanced Anti-Air Warfare (AAW) simulation involving an AEGIS FFG F-101 (Álvaro de Bazán) defending against a supersonic missile attack (Kh-22M ASM / AS-4 Kitchen).
During the critical intercept phase, when the enemy missiles were approximately 59nm from our frigate, we observed a green indicator near the enemy missile that changed in real-time:
In the initial SM-2 engagement phase, the indicator showed: 'Auto - 46.0' and 'Auto - 42.0'.
As the SM-2 approached the Kh-22M, these values constantly decreased.


Main Questions:
Could you please confirm if 'Auto - [Numerical Distance]' signifies the Planned Automatic Kill Point of the SM-2 missile, as calculated by the AN/SPY-1D Fire Control System?
What is the unit of measurement used for these distance values ('46.0', '42.0', etc.)? (We assume they are nautical miles).
We would greatly appreciate any information that confirms or clarifies the terminology used by the simulation engine for this crucial indicator.
Thank you very much, Correcaminos"
