ACG-45 (Progress Model 100531) by @fragmented_imagination (B Sanders)

An update on the ACG-45 from about five days ago. This picture features holes in the ribs, placed there so that tow lines can be attached to the hull. Also, on the front, I cleared out the blank space under the sensor strip by making it into an installation hatch for the ship's systems which are installed at the front instead of in the already cramped engine room. Still a bit of the way from being completed, but it's pretty close.
