The MBF-P02 Gundam Astray Red Frame is one of five identical prototype mobile suits developed by Orb using stolen data from the Earth Alliance's G Project. Its original concept was to be a MS that could be piloted by Naturals, and it was eventually loaded with an incomplete Natural-use OS. Most of the technology from the G Project is successfully copied with the exception of Phase Shift armor. In its place, the Gundam Astrays' designers made the machines out of a lighter foam metal compound, with minimal armor over the frame. This made the mobile suits lighter and faster than their G Project counterparts. All five prototype Gundam Astrays are also designed with a backpack that can be lowered to the back skirt armor, allowing the mounting of additional equipment on the back.

Like other mobile suits that use beam weapons, the Red Frame is equipped with hand plugs to exchange energy with weapons the suit carries. Although considered a misuse of the system, the energy from the hand plug can be manipulated into an energy ball and discharged. This is often used by Lowe as an emergency weapon, for example to temporarily blind enemies.
