Here are my ship designs from my Terran Ascendancy civ. (So far at least.) I'm only up to medium hulls right now.
Altarian type, 1.0X, No mods. In order in which I designed them (only four so far, heh)
The Ascendancy isn't a very aggresive race so I only have one type of ship designed for combat so far. They're researchers mostly... Of course with alliances then comes war... Also probably don't have anymore designs so far since each of my ships filled their role so well.. Heh.. ^^'' Now.. Lets see if I can do this image thing right...
Trade Runner - Speedy freighter / blockade runner.

Outpost Constructor - Answer to the slowness of Constructor ships.

Gaurdian Class Frigate - Basis of the Ascendancy Navy (Actually the only ships that aren't Gaurdians are about three defenders floatin' around my home systems... lol.

Assualt Transport - Now you don't have to worry about the issues caused by havin' two billion troops cooped up in a ship for three or four months! Now it's only about a month at most! ^^''

And for referance here's a pic demonstrating the differances between an Ascendancy "Frigate" and the stock Altarian Colony ship and Altarain Pheonix Class Cruiser.
