From what I could see in one of the recent videos it takes quite a few shots but it will totally depend on your reputation with that faction.If you're allied with them you'd be given a warning like in the recent videos with that sabre very heavy fighter,if you're are neutral they'll probably warn you as well or engage immediatly & if you're enemies well,it all goes down hill from there.

It mostly depends on how strong your weapons are relative to the strength of the ship you hit. If you have weak guns against a stronger ship, it will take a lot more hits. If you have strong guns against a weaker ship, it might only take a couple. If it's a huge technology gap, like a Titan against a Patriot light fighter, then they might only take one hit before they turn hostile, because that one hit might obliberate their shields.

i don't know about you but if im attacked by anyone...that isn't in my squadron he can kiss his you know what goodbye.
I guess we'll find out soon enough
