The RMS-117 Galbaldy β (Galbaldy Beta) was a mobile suit from the anime series Mobile Suit Zeta Gundam.
The RMS-117 Galbaldy β is an Earth Federation Forces upgrade of the MS-17 Galbaldy α. The upgrades were fairly simple, the most noticeable of which is the modification done to the armor of the mobile suits head, shoulders, legs and waist. The more significant upgrades include an increase in the mobile suit's performance specifications, such as thruster acceleration and power output. For weapons, the Galbaldy β is equipped with a standard beam rifle, a pair of beam sabers stored in the shoulders, a pair of signal launchers in the hands, and a new Federation-designed shield with a pair of single-use missile launchers to replace the Zulu-style shield of the original Galbaldy α. The head unit resembles the MS-14 Gelgoog, with a unique protrusion at the top of the head. A signal flare firing apparatus is included in the head, and its shutter opens to fire signal flares.
