The Explorer is public to use for anyone, though they would need to request Zoner turrets from the Zoners.
I doubt most of them have permission, and will most likely be told off by the Zoners, especially for using them to pirate Zoners and their close friends.
Really, without asking permission from any factions, Basics are the only Gunboat Turrets they can use I believe, though Zoners might be purple to them on the tech chart, meaning they can use them without asking the Zoners.
Yep, just checked, they can use Explorers and Zoner guns without any permission from anyone.
