It's one jump only, and with a Tier V tech that's improved to two jumps.

Here's something that Blair Fraser said on it once in the Discord, when comparing it to the Loyalists:

Blair Fraser, 24 May 2023: "There is currently no super weapon for the Loyalists by design (subject to change). They were already juiced up compared to the Rebels. With Loyalists we expect a creeping line of twin fortresses, deployable starbases, higher levels of garrisons, and titan beach-head support, etc. All the new (or improved) Rebel stuff in the update is to help bring them up to par with Loyalists and to promote a more offensive strategy compared to Loyalists. All subject to change based on how things go (i.e. nothing is written in stone)."

Compared to the Rebel's creeping Novaliths; they can also use the Titan's Novalith of course which is greatly offensive as well.

I see. I like the change then. Two jumps away is at least manageable.    I remember Blair from sins1. 

I am recalling correctly that the original supercannons in sins1 had a system wide range right?

Blair is either the Owner of Ironclad or the Co-owner (not sure); So yeah he's been here from the start.

And indeed, they could just fire from anywhere to anywhere. I think this is a way better direction to take, but they're still open to changing pretty much everything about the game so depending on how other factions work, different balance etc it might still change.

Yeah, the orbital mechanic works nicely with the change as you describe. And without it, creeping twin fortresses or novaliths seem actually somewhat fun. More of a grindy way to get there, but different from culture like in Sins 1 and it might make sure there is a possibility for a non-decisive victory.

I don't think I ever got the novalith to fire. Probably because I had no idea it was only one jump away I could fire it and I had built it at the back of my civilisation.

For one I am playing a game atm where every AI faction seems to be building novaliths everywhere no matter how many I expunge. It's really very annoying. All I am doing is jumping to random planets all over the centre of the orbital plane knocking out novaliths after they destroy my planets.... planets really do not last long enough against them for a response to be made. Shield arrays are just coming online to protect planets but they are too few and the novaliths popping up everywhere to be effective.

Additionally can we have the notification for a cannon shell show the origin as well. Often I am trying to find the origin after the fact and because the shell is gone their is no vector to see.
