The MBF-P03R Gundam Astray Blue Frame 2nd Revise is the improved form of the MBF-P03 Gundam Astray Blue Frame Second L developed by the Serpent Tail with help from Lowe Guele. It first appeared in the photo series Mobile Suit Gundam SEED VS Astray. The unit is piloted by Gai Murakumo.

Using combat data obtained from the Gundam Astray Blue Frame Third, the Blue Frame Second L was upgraded into the Gundam Astray Blue Frame 2nd Revise. The new MS has better balance and its main weapon, Tactical Arms II, is an improved version of the original Tactical Arms and has 2 new forms, Gatling Arm and Sword Arm. Blue Frame 2nd Revise retains the other weapons of Second L as well as the Trans Phase Armor system around the cockpit. It also stores additional power packs on its rear skirts, which are often used together with the Gatling form. Like the original Blue Frame, the Blue Frame 2nd Revise can be equipped with the Scale System for aquatic missions.
