The Deron War Craft C-Fighter ARC-6 is the replacement for the ARC-4 (Late) , since the ARC-5 was never intended for production.
Differences over the ARC-4[]
The ARC-6 is the first C-Fighter to feature a fully functioning Anti-Gravity Propulsion System, for both landing and standard flying. It also has one large landing unit rather than the two connected ones of the ARC-4L. The ARC-6 debuted just as many squadrons were looking for replacements for old, home-built fighter craft, and was well received because of this. It replaced a number of these craft, and some ARC-1s and ARC-2s as well.
"ARC-6S"[]
As part of the debut of the ARC-6, DWC produced a special "ARC-6S" C-Fighter, or "ARC-6 Sport", as a gimmick. It was painted all black with red racing stripes, tinted cockpit glass, a racing-style bucket seat for the pilot, and a large rear spoiler, despite there being no air in space. This unique craft made a tour of numerous squadrons and air shows, before being donated by DWC to Deron's Ship History Museum [1].
