Technology and Combat Characteristics
An early miniature transformable mobile suit developed by Anaheim Electronics, the RXR-44 (F-50D) Guntank R-44 was based on an older transforming artillery mobile suit, the D-50C Loto, a special operations mobile suit created in UC 0096. Due to its compact size, the 200mm main cannons mounted on its shoulder had to be loaded manually. A feature carried over from the D-50C Loto, not shared by most other Mobile Suits, was its main torso containing enough room for four personnel to fully operate the unit and transport a small ground force.

During the early half of the second universal century, the Earth Federation came to a period of peace it had not known since the first half of the first universal century. Because of that peace, there was no need for a stealth/infiltration mobile suit and the Loto was retired. At this time, Anaheim Electronics created the Guntank, a new small scale transforming artillery mobile suit based on the Loto. The overall design proved to be a failure, however, and the Guntank never made it past the prototype stage. It is unknown how many prototypes were manufactured, but it is confirmed that at least one unit later came under the ownership of Roy Jung, curator of a war museum at the Frontier IV colony. Roy refurbished the unit and personally gave it the unofficial model number RXR-44 (with 44 being his age when he acquired the suit around UC 0107). Roy would take his prized RXR-44 into battle with Seabook Arno in a futile attempt to help repel the Crossbone Vanguard forces invading the colony in UC 0123.
