F-50D Guntank R-44

The F-50D (RXR-44) Guntank R-44 is a variable mobile suit that appears in the Mobile Suit Gundam F91 movie.

History
An early 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. Due to its compact size, the 200mm main cannons mounted on its shoulder had to be loaded manually, and its main torso contained enough room for four personnel to fully operate the mobile suit. The overall design proved to be a failure, however, and the R-44 never made it past the prototype stage. It is unknown how many R-44 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). Roy would take his prized R-44 into battle in an attempt to help repel the Crossbone Vanguard forces invading his home colony in UC 0123.
