ok

Having the gravity generators in front does make it look good and gives it the classic look of a railgun, but it is not very wise. The gravity generators are much more protected in the back and also take up less space.

can you make a V2 with the gravity infront?

Space Engineers workshop is unnecessarily stupid and I am unable to update this after accidentally deleting the original blueprint. If you want to optimize the gravity fields, open up the control panel and view hidden items and search "gravity". Use 12m width, 150m height and 14m depth on every N N-1 and N N-4 gravity generator. Use 8m width, 150m height and 12m depth on every N N-2 and N N-3 gravity generator. I also recommend increasing minimum distance on "CANNON - Pistons" to 0.5m so the thing doesn't get claimed by Clang.

Comment if you need help with wiring things up.
