Okay I don't want to be mean, (the other, more expirienced shipbuilders are harsh, just to get their point across, don't worry) but you made all the classic n00b mistakes. Bad parenting, if you destroy that section just above the thrusters, it's bye-bye weapons. See those arrows? Those show the parenting. If section A has an arrow pointing to section B, then tha means if section A is destroyed, then B is destroyed too. Also, please use other colors besides stock green, the shades of grey are a good generic and beginner color. If you follow this advice, then you can become a great shipbuilder.
EDIT: Yeah, welcome to the forums.

A gay as fuck girl and loving it.
