I would love to learn how to draw vehicles like this. Any tips?

A few.. I actually learned to do this from watching Star Trek. The first thing I've learned is that when it comes to drawing your own, you need to figure out what it does and what you want it to do. Basic shapes are a good start as always, but slowly but surely go back over it in a little more detail.

I do generally start out with basic shapes, but it seems when I add more details I always manage to make it look worse than if I would have had just left it at basic shapes/outlines. However, adding the whole 'what it does and what you want it to do' may actually change that since, in truth, I've never given a vehicle or ship I've tried to draw a purpose other than 'ZOMG BE A SHIP ALREADY' so I may give that a shot in my next attempt and see if that make any difference. Thank you for that.

It's a trial. After all when people actually make vehicles they think more about the functionality than they do the first initial look. The look comes afterward.

I like the look of this craft. What became of this design? If it's abandoned I'd like to take it on.

I'm searching a ship design to draw for my story.

It's definitely not abandoned. It's just being overhauled and streamlined to incorporate multiple variations.
