Oberth Class Starship

Most famously appearing (briefly before going kablooey due to Klingon shenanigans) as the USS Grissom in Star Trek III

Note: Since originally posting this years ago, I've created my own, more detailed and accurate, version of the Oberth class which includes variants of the ship and Blender source files. You can find it here: https://www.thingiverse.com/thing:4766389
