My GOD so many rocks on the way.

Space Boat v1 had 4 guns, and died immediately.

Space Boat v2 had 10 guns, and manged to barely get there by manually pausing thrust several times, then getting smashed in orbit by Fulgora's drifting medium asteroids because it ran out of ammo.

Space Boat v3 has 28 guns protected by walls and a stockpile of ammo. It can get there and back again. Time will tell if it has production capabilities to survive parking in Fulgora orbit.
