Sansha Fortress

So today I was scanning around the system and had found somethng called a Sansha Fortress.
I had tried this before in my Harbinger and got my ship squished within 1 minute but this time i was feeling confident since i had tanked a sansha 6/10 a week before but i decided to call a friend ina drake with a remote repair for back up. So the results? i managed to kill a frig and warp out where my friend got his Drake blown up... yeah... so i sent him 60mil to replace his ship, since i did lure him to his death hahahaha.

Well what information can i give? Yeah google sucks and gives no info for me....

on Warp in there were

2x Sansha Cruise Missile Batteries (EMP)
2x Sansha Stasis Towers (Web)

Group 1
4 frigates - web and scram

and another 4 groups with like a total of over 10 battle ships and about 4-6 frigs and cruisers

It think these can be aggroed seperately just dont shoot the towers! of course if you die dont blame me... ya so erm I wouldnt try that again that complex alone has cost me 100mil in ships and all i got in return was maybe 50k back from the frigate i killed...

Yea well one day if i can i will do a full guide to this if i can do it. Theres not much information on this particular plex on google.. but its got me annoyed
