RX-107 ［Rosette］ Enhanced Land Battle Form

The RX-107 Rosette Enhanced Land Battle Form is a mobile suit that appears in the novel Advance of Zeta: The Flag of Titans.

Technology & Combat Characteristics
The Enhanced Land Battle Form of the RX-107 “Rosette” is a ground combat form of the RX-107 used when the Murphy Team assaulted Karaba’s Kamchatka base. Capable of performing high-speed ground combat, This configuration is equipped with option parts that give this unit the ability of high-speed hovering movement. The Enhanced Land Battle Form features a hovering skirt unit that runs powerful thermonuclear jet engines whose great thrust output enables the machine to hover. Unlike conventional thermonuclear rockets that generate thrust by consuming propellant, the principle behind the Enhanced Rosette's thermonuclear rockets was relatively simple: motion of the mobile suit pushed air in through the front of the mobile suit (ram effect), a nuclear reactor heated the air, and then the hot air expanded at high speed out through a nozzle at the back, providing thrust. These thermonuclear engines not only burned less propellant, but greatly extended the unit's mission operating time.

Because the nuclear thermal jet engines of the Enhanced Land Battle Form required considerable forward speed to operate well, they can essentially travel only straight ahead, incapable of high-speed maneuvers. The mobile suit itself has been converted to the same version as the standard RMS-108 Marasai, and is equipped with latches attached to its back and right shoulder that can support a shield booster and the large beam rifle used by the atmospheric version of the TR-3 Kehaar. Its chest component is protected by an armor unit similar to that of the Hizack Cannon, with a spread beam gun installed in the center.

Several other ideas were considered and discarded between the prototype plan and the final version. The hovering skirt unit was originally intended to house a compact Minovsky craft system, but this was omitted because the system couldn’t be made small enough. It is speculated that this unit was developed with flight in mind, but it failed to produce enough thrust, so its function was shifted to that of a high-speed hover unit.
