Technology & Combat Characteristics
The Blue Frame Second L is created after MBF-P03 Gundam Astray Blue Frame is damaged in battle against the Socius clones, and combines upgrade parts that Gai designed, with upgrade parts developed by Lowe for his MBF-P02 Gundam Astray Red Frame. In addition, its cockpit is now protected by Trans Phase armor. The parts that Gai designed (new feet and shoulder armor) are already in production before the fight, but did not make it in time. The new, smaller feet give the MS better jumping power and are mounted with retractable "Armor Schneider" combat knives in the heels and toes, which could be used as kicking weapons or as anchoring spikes. The new shoulders contain fin thrusters to improve the suit's evasion capability, and can also be used to make unexpected sideways maneuvers during battle. Two other combat knives are also equipped on the hips.
The new head and "Tactial Arms" backpack are developed by Lowe for his Red Frame, but are instead used to repair the damage Blue Frame so that the process can be expedited. The "Tactical Arms" is a flight unit equipped with a 90mm Gatling gun, and can be detached and reconfigured as either a hand-carried gun (aka Gatling form) or a huge 20 meter sword (aka Sword form). The new head has increased armor for better protection of internal electronics and through its antenna, short range remote control of the Tactical Arms is possible. Blue Frame Second L also stores additional power packs on its rear skirts and they are often used together with the Gatling form. It could also carry an additional weapon: a mobile suit sized version of the Archangel class assault ships' Lohengrin Positron Blaster Cannons. The suit's battery was later replaced by Morgenroete Inc. with one that has higher performance, this improved the suit's operating time by 30%.
There are 2 configurations of Blue Frame Second; Second L is the configuration that includes parts developed by Lowe, hence the "L" in the designation, while Second G is the configuration that only includes parts designed by Gai.
History
While on Earth during the First Alliance-PLANT War, Gai Murakumo and his MBF-P03 Gundam Astray Blue Frame battled against rogue "Combat Coordinator" Eleven and Seven Socius and their GAT-01D Long Daggers. During the battle, Blue Frame's backpack was destroyed and its head removed as proof that the Socius clones defeated Gai. The damaged Blue Frame was later transported back to Morgenroete Headquarters in Orb Union for repairs.
Coincidentally, Lowe Guele was also in Orb to collect upgrade parts for his MBF-P02 Gundam Astray Red Frame and witnessed the damage Blue Frame. Due to injuries he received during battle, Gai was unconscious for a few days and the repair work was left to Lowe and Erica Simmons. Lowe then donated Red Frame's upgrade parts to expedite the repairs and came up with the two layer armor system around the cockpit. Erica then ordered the use of spare PS armor from MBF-02 Strike Rouge to be used for this two layer armor system. The upgrade parts that Gai ordered prior to the battle with the Socius clones were also ready and fitted on Blue Frame. All these modification resulted in the creation of Gundam Astray Blue Frame Second L.
After awakening, Gai immediately used Blue Frame Second L in a rematch against the Socius clones and won. Gai then used the Blue Frame Second L for various missions. One mission he was possibly hired for, or where he simply decided to help Lowe, was to take out the MBF-P01-ReAMATU Gundam Astray Gold Frame Amatsu which had been destroying ZAFT mobile suits and ships. Gai lent Lowe the use of the Tactical Arms, with which Lowe's Red Frame was able to cut off one of Gold Frame Amatsu's arms. With Gold Frame Amatsu damaged, Gai took the opportunity to use a Armor Schneider to critically damage the mobile suit, killing its pilot, Rondo Gina Sahaku.
Later, in the battle against the huge mobile armor TSX-MA717/ZD Pergrande, Gai equipped the Blue Frame Second L with a Positron Blaster Cannon. During the fight, Gai moved the Blue Frame Second L to point blank range (within influence of the Pergrande's N-Jammer Canceller) and destroyed the Pergrande with a single shot from the Positron Blaster Cannon. The Blue Frame Second L was eventually modified into the MBF-P03R Astray Blue Frame 2nd Revise.
