Developed shortly before the Terran-Cyrvan War, the Ray Mk II fighter was the posterchild of second gen fighter technology. During the time, it was the mainline fighter used by the League Star Forces. It has since been replaced by the Ray Mk III. The Ray Mk II still serves within Sol Force and Commonwealth Royal Fleet forces.

The JS version is the result of a massive retrofit project, giving it many features that third-generation fightercraft have.
