Ship depicted by Elmore on box front

Does anyone know if the ship depicted on the SF box front was written up for KH rules? I've assumed over the years that it's some sort of armed shuttle, but I wonder whether it might be something else. It'd be fun to draw the rest of it <img src="http://www.starfrontiers.us/modules/tinymce/tinymce/jscripts/tiny_mce/p…; alt="Wink" title="Wink" border="0" />
