Here the beginning of a photon torpedoe launcher on the front of the ships saucer.
After a few slices and booleans I now have some hull details and the underside of the saucer.
Since I remade the bridge of the ship and it differs even more from the original design. I decided to make another adjustment. The original design had two blue balls on the bottom the saucer. I decided to make the blue part smaller, I like it better this way before it was kind of silly.
Here you can see that I've thickened up the neck a little. It wasn't even wide enough for a person to get through and it looked flimsy as hell.
