Ships & Modules

You're looking for Recon cruisers. Each race has two of them which are bonused for their racial ewar, one of them stronger and one of them somewhat weaker, but able to use a covops cloak. They each (except Cal) also have a secondary type of EWAR which they can do, but is rarely used in fleets.

Amarr: Neuting (Tracking Disruption)
Curse
Pilgrim (the cloaky one)

Caldari: ECM
Rook
Falcon (cloaky)

Gallente: Long range warp disruption (sensor dampening)
Lachesis
Arazu (cloaky)

Minmatar: Long range webs (target painting)
Huginn
Rapier (cloaky)

They are all custom designed to be amazing fleet support ewar boats. Talk to the gangs you're flying with and see which one is the most in demand with those fleets.

If you have proper logi support, you should be able to buffer fit them to survive ok. In any fight that's small enough for them to make a difference, then proper logi support will be able to keep you alive if you're fit right. Any fight where you'll be alphaed off the field or you wouldn't do enough to help your fleet, then you're probably better off in a DPS BS anyways.

Recons do have less tank than a BS, but they also have lower sig and T2 resists, making it much more feasible to buffer+sig tank them and let logis rep you up.

Edit:
tl;dr: Yes, they could die instantly in a big enough fight, but they wouldn't be doing enough to be worthwhile in that big a fight anyways. Fights that large are pretty much just alpha and Logis and that's about it.

You could also look into Interdictor/Heavy Interdictors too, they specialize in making a bubble that keeps the enemies from warping away (and HICs are specifically designed to be able to tank a supercap for a while to keep it from leaving, they can get big tanks).

You want larger fleet engagement EWAR ships?

Then its the Falcon. Jam, cloak, warp somewhere else, jam, cloak.
Or the Scorpion well-buffered and supported by logistics.

Domi is not really an EWAR ship, lacks range and bonuses.
Frigates lack range or EWAR power to fight BS gangs.

Thanks guys, you've really shed some light on the topic!! I think although the Scorpian does look like a good ECM boat, I will probably go down the Amarr route for the Curse and then the Minni route to end up flying the Bhaalgorn (in 8 months+ time what?).
That ship looks like a beast and I didn't take in the smaller signature of the Curse which may mean I can survive engagment if I need to!

Thanks!

For small gangs, the Curse is a beast. I flew my first one a little while ago, and I can confirm that it was intensely satisfying to disable multiple ships simultaneously, while taking a pretty large amount of fire. I can't say as to its effectiveness in BS fleets (its neuting range is a bit short for that) but I'm sure there's some way to make it work.

Yes this part makes me sad, i'm fully aware that i'm a good 3-4 months off before flying T2 Cruisers :s even then i'm sure there will be support skills i've missed. I guess T2 guns aren't essential if i'm doing EWAR or neuting etc...

As for the cost of a Bhaalgorn, definately for special occasions but at a cost of 2bil (bit more?) it shouldn't be that much of a problem by the time I get to it.

The thing I really hate about this game :S How long it takes...

Get used to long trains. The more level 5 skills you accumulate the more you will find more of them to train and waiting for the better part of a month to comlete something.

Actually, even though you feel the way you do now, the long wait is what makes this game great. There is a real sense of achievement when you get into tech II ships or capitals. Or gain access to another level of tech II weaponry. If you've ever trained in martial arts, think of it that way.

edit- as to your OP, for tech II support for "fleets" that is not a logi, you can't beat a dictor or heavy interdictor.

Uh ... Waiting for something is accomplisment ? You dont have to dock from a station even once before your able to fly capitals .. its only takes time.

Where the hell is the accomplisment in that ?

There's something fundamental that you need to realize before making a decision. Because you say you want to do dedicated ewar, and to fly in big fleets. So know this:

Dedicated ewar does not scale well with fleet size.

Dedicated ewar ships are most effective in smaller gangs, where it is easier to distribute the ewar among targets and the force multiplier payoff is much larger. Recons are gold in small gangs.

In larger gangs, managing ewar is chaotic and difficult, to the point where most large fleet doctrines don't incorporate an ewar wing. Sometimes you'll see Scorpion wings, but even that isn't very common. Generally large fleets prefer to use their manpower to bring more DPS or more reps.

Anyway, consider all that before committing to a path. Most experienced PVPers seem to enjoy small gang action more than large fleet fights, so maybe what you really want is to do dedicated ewar in a small gang, where you as an individual pilot can actually make a difference in the fight.

But if you do want to go for large fleets, distributed ewar is what you'll encounter more often. Distributed ewar means putting ewar modules on the majority of your ships, even though they are not bonused for ewar. The large number of ewar modules can be as effective as a small number of dedicated ewar ships, with the bonus that your fleet's ewar cannot be easily taken out by the enemy.

So much more to say, but I'll leave it at that.
