In Eve, ECM (Electronic Counter-Measures) modules (like Jammers), don't work on NPC pirates (as I once found out the hard way). But looking at EVEMon - it seems that ECM is a subset of the EW category. And there's a lot of different EW (Electronic Warfare) type of modules, like Target Painters, etc.

Do any of these EW modules work on NPCs? (Or the EW drones?) Or are NPCs just immune to everything in the EW category?

Out of all the Electronic Warfare modules, the Target Painter is the only one that really works on NPCs, since it just increases their signature.

The others do have a slight chance to work on rats but NPCs have a tendency to cheat when it comes to EW, so it's usually not worth it.

Except sleepers, sleepers hate Ewar! Also, i believe the goal is to make NPCs more "real" similar to sleepers. – Kevin Peno Apr 21 '11 at 20:53
If you include propulsion jamming and cap warfare in EW then Nos will 'sort of work' (you'll gain cap but they won't be impaired at all) and webbys still work. – qoonpooka Jun 8 '11 at 13:28
