The Roach is Fortia's main fighter. Originally, it's development was set in the back burner due to the lack of aerial enemies. This changed after reports of hostile aircraft started pouring in from long-range raids caused fears that terror bombing would one day be paid in kind.

After the first few Roaches came out of the lines, their production would soon be put in priority after a raid where a Crane Fly was followed home by two airplanes which proceeded to destroy it and a second one on the ground, as well as 8 Earwigs. This raid also damaged 5 more planes of the latter type and inflicted 35 casualties, including 17 deaths.

It's armament consists of 10 .30-caliber MGs.
