I generally dont add the mobility stats unless i remember while playing survival (which iv never done yet :D) plus trying to get a 130% crew just to get the numbers is a pain but its fairly fast and has good mobility for its size, you must remember its a 15 slot battleship. But i think its about .22/.22/.30 or something like that... im really not sure.

Well iron and titanium are the fastest to mine.

If its a non avorion craft it will use iron inertial dampeners and with a massive ship you need alot.

As for titanium thats used for mostly all the other internals due to light weight and again, easy to mine. However in most craft its also used for the armor too.
But im unsure if thats the case here. From looking at the stats i really only use trinium for hanger/production internals so the fact that its over 1mill im fairly sure its armored in trinium too.

What are the other stats like thrust, brake, turning, etc.? Also, why so much Iron and titanium?
