The Blue Flame began production after the Word of Blake took possession of Terra. The same factory that had produced the Shootist was upgraded to produce four legged BattleMechs. The Blue Flame is an extremely stable platform due to its quadrupedal configuration.[1] In the later years of the Jihad, an engineer who had help build the Mech stole the design specs and later created the Thunder Fox.[4]

Weapons and Equipment[edit]

The Blue Flame's primary armament is two Diverse Optics Sunbeam ER Large Lasers that allow the 'Mech to engage the enemy at long ranges. It also has three Hovertec Streak Streak SRM-2 launchers for close range combat.[1]

The 'Mech is built around a Dennenbach-Mitchell Series 8 Endo Steel that cradles a VOX 225 Light Fusion engine that gives the 'Mech a top speed of 86.4 km/h. The Blue Flame carries an impressive eleven tons of StarSlab/2 armor and has ten double heat sinks. To allow the 'Mech to share targeting data with friendly units, it is equipped with an improved C3 computer that allows it to exchange information with other C3i equipped units.[1]

In German products the unit's proper name was translated to Blauglut, which rather translates to Blue Blaze. The model code was accordingly changed to BLG-21.
