Is there any AI art engine that draw ships images?
I've looked into a few. And they're getting better, but not top-down and not consistently, no.
With a lot of fidgeting with prompts, I would get something like this:
Prompt: "Create a 2D top-down aerial view of a futuristic science fiction spaceship with a cruiser hull size. The ship should have sleek and aerodynamic lines, and be equipped with advanced propulsion systems and energy shields. The background should be completely white and empty, allowing the ship to stand out. The final image will be used as a video game art asset, so make sure to include details that will enhance its visual appeal and make it an engaging element of the game's universe. --v 5"

^^^ prompt language is corny. Midjourney likes a lot of hyperbolic descriptors...at least it did with v4 and v5.x.
Even so, you're still wrestling with it constantly...and if you're trying to build a cohesive ship set, it's all the more frustrating. You end up tossing 30-40 images for 1 or 2 workable ships...and they still would need some additional photo editing for cockpits/weapons ports etc. Midjourney is arguably the "best" at it, but they don't allow for things like weapons...so there's no weapon ports or missile launchers...those would need to be edited in as well.
Portraits were largely the same...but was do-able after a long time. I spent most of my time coming up with the prompts that would tease out some consistency...having to use turns of phrase and word tricks to get the aliens to look somewhat like one another.
Here's the prompt I used for Arm diplomats: "Generate a highly detailed portrait of an alien diplomat, a bipedal humanoid species with glowing purple eyes who always wear full tribal face coverings and tribal clothing inspired by the Akhu Tribe of Kengtung Myanmar. Shot with a Sony Alpha a7 III camera and natural light against a blank gray background. --v 4"

I went for a variety of Earth cultural clothing inspirations to try and give each of the 40+ species some individuality. Same went for animal inspirations. Some are more obvious than others.
Blender has a space-ship creator plugin that does really good procedural spaceship generation...but then you'd have to texture/paint it...would still take some hours for a single ship :p
I haven't outright looked at the AI space in a couple of months, so there might be some advances I'm not aware of. Midjourney did great things for portraits when they went from v4 to v5.x. But most of their stuff is centered around portraiture.
