The idea behind this ship is having a carier ship. It is not made for any form of combat and just to transport people and items. This means it would be a large ship and the reason behind the big engines on the back of the ship. To make this ship i mainy extruded a cube and adjusted the thickness of it depending on what part i worked on. To make the exhausts on the back I selected a cylinder and reduced the sub devisions.
Here is my concecpt idea for this ship.
