The perfect Nano Gang consists of several important components:
> Loki - giving bonuses, point range, scan res, etc., sitting cloaked somewhere in system.
> Tackle Drakes - 34k point with bonuses (Pilots need Low Grade Snakes to make it work) Typically Long Point, 2 Webs, very little tank because you won't need it.
> Scimitars - And this is why. With Scimi and Loki Bonuses, you should never be caught, never in range, and faster than anything else on the field that could be a threat.
> Optional - An Arazu is always a great choice as scout. In a pinch the Loki can do it, since it is always good to have bonuses in the system you are going into.
That is the foundation composition for the perfect Nano gang. The great thing about it is scalability, it can work with a minimum of six ships (although it works best with at least eight) and up and up. In my opinion the perfect gang size would be, 1 Loki, 6 Drakes, 3 Scimi, 1 Arazu. But that can be more or less.
Drakes sit 30k from the enemy, remember they have 34k points, and hammer away with missile spam. They are fast enough (with Nano in the lows and Loki bonus) that nothing on the field can catch them. Except for small stuff and that's what the webs are for. (Anything small that tries will be doomed) Scimis sit 30k away from the Drakes and serve as the Drake tank.
For those that can't fit the Tackle Drake (and it does take excellent skills and low grade snakes to fit properly) the Tank Drake is the next best option. You lose a web and some agility and some range, but it's better than nothing. For those that can't fly either Drake, the Artie Cane is the next best choice. It doesn't need the snakes, but you're losing DPS and EHP. The Harbi would be the last BC option in this set-up as it doesn't come close to the range, etc., of the other two. In fact, you'd be better off using a Zealot instead.
It is nice having a couple of Artie Canes along if possible and have them focus entirely on Alpha striking small tackle from range. They work great for that purpose.
And no, I am not giving away fits. Or any other specific details on how this all works. There are probably plenty of other sources out there, but for us in Lucifer's Hammer and Burn Away, we've been working on this for a very long time. In fact we sorta became notorious for it for awhile there. Our Alliance name comes from this gang doctrine for goodness sake! LOL. But we don't run these like we used to, like anything they've sorta fallen out of fashion. But that doesn't mean it isn't still a valid fleet doctrine.
And honestly it doesn't take a rocket scientist to figure it all out. The keys are the Loki (and really the Loki is the only real choice here, I've seen people do it with the others to mixed results.) the Tackle Drake and having the Logi along. Without Logi this turns into a Nano Strike Gang, which is different in many ways. But that's still something I'd rather keep to myself for awhile.
Can't give away all my secrets now can I?
