As per Xfozzboute’s request, here are some images of the Equinox and the Excalibur, a scout and a destroyer.
First, the Scout-class wessel Equinox:
And the destroyer, Excalibur:
Aside from the textures, the differences between the models are the windows, sensors and weapons. The scout has only minimal weaponrs but it has lots of sensors and more windows. The destroyer has less windows, only minimal sensors but it has enough weapons for 3 heavy cruisers.
