This ship can be several different ships. It's made of modules that can be switched out really quickly. My son loves Lego battles, and the more interesting the story, the better. Maybe there's an ambush, or an important figure gets kidnapped, or someone stows away in a freighter to spy on the enemy. This kit lets him take his story wherever he wants it to go. This YouTube video
shows how easy it is to change from one ship to another. You can also add to or change the 'thrusters' module to make the ship into whatever you want.
I remember watching the Apollo program on TV, so I gave this a Service Module, like those ships had. It's a little more futuristic, because it has an oval cross-section, instead of being just a regular cylinder. It makes a pretty cool shape for a Lego ship.
