The MBF-P03 Gundam Astray Blue Frame is a Mobile Suit in the manga series Gundam SEED Astray and the photonovel Mobile Suit Gundam SEED Astray B . It is piloted by Gai Murakumo.

Technology and Combat Characteristics

The MBF-P03 Astray Blue Frame was one of five identical prototype combat mobile suits developed using stolen data from the Earth Alliance's G Project and was designated for testing optional equipment. Its computer contains data and blueprints for various optional equipment. Most of the technology from the G Project was successfully copied with the exception of Phase Shift armor. In its place the Astrays' designers made the machines out of a lighter foaming metal compound and were built with minimal armor over the frame. This made the Astray mobile suits lighter and faster than their G Project counterparts.

Originally, the Astray Blue Frame was armed with the standard armament of the other prototype Astray suits. These weapons include two head-mounted "Igelstellung" 75mm multi-barrel CIWS, two back-mounted beam sabers for close combat, a Type 71 beam rifle, and a single physical shield. However its mercenary pilot used his resources to outfit the Astray Blue Frame with a wide variety of equipments to suit multiple combat situations and to meet the needs of diiferent mission. Like the other prototype Astray suits, Astray Blue Frame's backpack can be lowered to the back skirt armor, allowing the mounting of additional equipment on its back.


  • "Igelstellung" 75mm Multi-Barrel CIWS
Mounted in the Blue Frame's head are two "Igelstellung" 75mm multi-barrel CIWS guns. Although classified as anti air, these light projectile weapons can be used to intercept missiles and to destroy lightly armored vehicles.
  • Beam Saber
Blue Frame is equipped with two back-mounted beam sabers for close combat.
  • Type 71 Beam Rifle
The type 71 beam rifle is the standard ranged beam weapon of the Orb military. The beam rifle fires an energy beam that is highly effective against most targets, such as mobile suits, but is less effective against targets designed to take beam attacks, such as laminated armor or shields treated with an anti-beam coating.
  • Shield
Blue Frame can use a physical shield for defense, it is mounted on the left forearm and/or handheld. This is the same type of shield as used by Strike and Duel Gundam.
  • Supercavitating torpedo launcher
A handheld weapon used by Blue Frame when it is equipped with Scale System. The rifle is mounted with 6 supercavitating torpedoes for ranged aquatic combat.
  • Combat Knife
A pair of combat knives are mounted on the Blue Frame's hips when it is using the Scale System. These knives are the suit's main close combat weapons when it is underwater, as the beam sabers cannot be used in aquatic environment.
  • Full Weapon Form
As a mercenary, Gai often gets himself into lopsided MS battle, thus he designed a "Full Weapon" form for Blue Frame in which the MS is loaded with multiple bazookas and missile launchers that are also used by ZAFT's mobile suit. These equipments do not use much energy and allows Gai to fight multiple enemies easily. He used this form when he was guarding the Eurasian Confederacy's Artemis space fortress.
  • 8-tube Missile Launcher
  • M68 "Pardus" 3-Barrel Short-range Guided Missile Launcher
  • M68 "Cattus" 500mm Recoilless Rifle

Special equipments and features

  • External connector
A connector for attaching additional equipment to the back of the suit. It is similar in function to the hardpoint on the back of the Strike Gundam. The connector is exposed when the backpack is lowered to the back skirt armor.
  • Complete sensor unit
Constructed using the blueprint found within Blue Frame's computer, the complete sensor unit is an optional head equipment. It greatly increases the MS’s communication, sensing capability and information processing power. On the flipside, the various detectors in the sensor unit are very energy draining and processing of the complex data place a heavy burden on the OS. The sensor unit contains a dedicated computer to process these data.
  • High speed booster
An optional booster unit developed by Serpent Tail in order to recover data from a high speed spaceship that lost control during testing. It seems to be attached to the suit through the external connector.
  • Scale System
For aquatic mission, Gai can equip Blue Frame with a "Scale System" armor, which has numerous tiny scales that vibrate to propel the mobile suit through the water and can also serve as makeshift shield against phonon maser. With these parts, Blue Frame has higher underwater mobility than ZAFT's aquatic MS but the diving depth is relatively limited, since the mobile suit itself is not built to resist high pressures. Additional sensors such as active and passive sonar have also been installed in the Blue Frame's head. This set of equipment was built by Morgenroete Inc. under Erica's command and serve as payment for employing Gai to complete certain missions. The equipment proved itself in battle on Giga-Float against Gold Frame, in which Gai fought off Rondo Gina to protect the installation. The back mounted portion of the Scale System seems to be attached to the suit through the external connector.


The Orb Union's Morgenroete corporation built five Astray prototype mobile suits at Heliopolis, the MBF-P01 Astray Gold Frame, MBF-P02 Astray Red Frame, MBF-P03 Astray Blue Frame, MBF-P04 Astray Green Frame, and MBF-P05 Gundam Astray Unit 5 (which was later modified into MBF-P05LM Gundam Astray Mirage Frame) which were based on the five G Project Gundams that they assisted the Earth Alliance's Atlantic Federation in creating. They successfully copied the EA's beam rifle and saber technology, but Morgenroete did not have access to the Phase Shift armor design, and compensated by making the Gundam Astray units lighter and more agile than their EA counterparts. Unlike Gold Frame, Blue Frame was fitted with only Orb hand plugs, and thus could not use Earth Alliance weapons.

On January 25, CE 71, ZAFT's attack on Heliopolis to steal the Alliance Gundams also unknowingly interrupted the Astray project. In order hide their progress, Orb's officials decided to destroy the Astray lab. Coordinator Rondo Gina Sahaku, an Orb nobleman, disagreed and attempted to save the save the three suits, Gold Frame, Red Frame and Blue Frame, that were assembled. He ordered one of his subordinate to split all the Astray data among the three MS and Blue Frame was uploaded with specifications for a variety of optional weapons and equipment. Blue Frame was soon located by Junk Guild technician Lowe Guele, who found himself having to use it to protect himself from Coordinator mercenary pilot Gai Murakumo of the Serpent Tail company, who had been hired to eliminate all evidence of the Astray program. Over the course of the conflict, Lowe abandoned the Blue Frame in a ploy to disable Gai's Mobile Armor. When the Serpent Tail were seemingly double-crossed by their employer (having seen the suits, Gai himself had become evidence of their existence), Gai commandeered the empty Blue Frame to defeat them, and after Lowe confronted him in Red Frame, Gai decided to leave the Junk Techs alone. Gai kept Blue Frame for his own use, and the two Astray pilots encountered one another several more times, sometimes as allies, sometimes as enemy and they soon became friends.

Blue Frame was later severely damaged in battle against rogue "Combat Coordinator" Eleven Socius and Seven Socius in their GAT-01D Long Dagger, and was subsequently upgraded into MBF-P03 Gundam Astray Blue Frame Second L.



In Gundam Memories, the Astray Blue Frame, along with the Red Frame, is unlockable after all modes, Story and Mission, are completed.
