MFC signature vs passive detection
« on: September 22, 2021, 10:14:32 PM »
Two questions:

1. Is a MFC "always on" from the standpoint of an enemy trying to detect it? If not, when does it start "transmitting", e.g. when you assign it a target, when you click Open Fire for that MFC, etc?
2. On a related topic, if you have missiles still guiding to the target (with no sensor on the missile), and you click "Cease Fire" on the MFC that fired the missiles, will the salvo self-terminate?

1: MFC's do not emit anything, and are not detectable. They rely on separate active sensors to paint targets for them to lock on to.
2: No, AFAIK there is currently no way to terminate a missile in flight, the only ways missiles will terminate is it running out of endurance or it hitting a target.

edit: addendum to 2, I think if you lose target lock via losing the active sensor contact, or moving out of the FC range(?) the missiles will terminate as well.

For a MFC I'm looking at researching right now, there's a line for "Signature vs Passive Detection" (see below), which I took to imply that it would be detectable...

Anti-ship MFC 113Mkm
Resolution 200   Range vs 10,000 ton object (or larger) Range 113.1m km   
Range vs 1000 ton object 1.1m km
Range vs 250 ton object 70.7k km
Signature vs Passive Detection: 4200
Cost 21.0   Size 50 tons   Crew 2   HTK 1
Base Chance to hit 100%
Materials Required: Uridium  21

Just tested it, I placed a ship of race A with large passive EM and TH sensors out in space, and 50m km away I placed a ship of race B with active sensors with 50K signature, and another ship at 40m km with a missile fire control with 50k signature as well. The ship of race A could detect the active sensors, and could not detect the missile fire controls. Even after firing the missiles and guiding them in on target, at no point did the ship from race A detect the missile fire control, despite it being closer than the active sensor.

In the class display tab as well, the missile fire controls don't list a value for GPS, which is the signature strength. Fairly certain it's included on the component summary by error.

Tested again at point blank range, close enough to detect the strength 3 thermals of the ship from race B and there was no detection of the missile fire control, during launch or guidance.

That line in the MFC description is a bug and should only appear for active sensors. I've fixed that for v2.0.
