This is the fourth set of Feng Zhu "concept" ships, commissioned for an unspecified Wing Commander title following the release of Secret Ops. These are labeled as "multi-roles", which creates more questions than answers. Thanks to the convenient scales they seem to be larger than fighters - but not by much. Could they be Privateer-style civilian warcraft? They do seem to be heavily armed!
Thanks to Captain Johnny for both archiving and providing this material!
