[PvK]

No propulsion uses supplies during combat. All engine supply use is out of combat.

The closest thing that comes to mind would be a drone that has enough supplies to launch a seeker, and then runs out of supplies and I assume vanishes. I'm not sure it would vanish in combat though - it might become a ram-drone at that point. No really good solution comes to mind with the tricks I know of - that's about as close as occurs to me.

I think I would just use seeker weapons.
