This is the federation starship Reliant NCC-1864, Miranda class.
This is the ship Kirk had to fight in that famous battle scene from Star Trek 2. The Miranda class vessel can be seen all throughout the Star Trek universe. In fact, this design has been in use for at least 80 years. Must be one heck of a ship.
I like it. If only all Trek movies were as good as Wrath of Khan ;-)
I'm wondering if the nacelles might not be long enough going back. But in the top down pic, the saucer part might look bigger due to photographic physics then being that way in reality
