SO Ship Viewer
This patch is based on the ship viewer in Wing Commander Prophecy, but this version adds all of the new Secret Ops ships, Terran capships, Kilrathi designs and even Nephilim vessels. It also shows alternate versions of some craft, such as the Midway with plasma gun and the destroyed model of certain ships. It's really impressive how many models are in the game.
Just unzip this small file into the Secret Ops folder, and then click on the small sphere above the holographic Cerberus in the game's ready room (normally the "Prophecy" easter egg). It may be worthwhile to set this up on a separate game installation, since it could temporarily impact normal function.
