The Icarus Unit was an equipment option for the RX-121-1 Gundam TR-1 [Hazel Custom] based on the concept of unassisted mobile suit flight under gravity. Lacking the ability to transform from mobile suit form to flight form like the NRX-044(R) Prototype Asshimar TR-3 [Kehaar], this revolutionary system achieved flight through brute force, thanks to the high thrust produced by the powerful thermonuclear jet engines attached to its lower body and the thermonuclear rocket engines in its shoulders. The Icarus Unit’s shoulder parts could swivel forward 90 degrees for storage inside the ORX-005 Gaplant TR-5 [Hrairoo], and they had option latches for attaching weapons, shields, or sub arm units. The wing-like devices in the shoulder parts functioned as attitude stabilizers during flight. The waist parts contained a supplemental generator similar to that used in the Hazel Custom’s movable booster pod, albeit somewhat larger. In the early stages of the aerial combat unit development project, the plan was to equip the Icarus unit with aerodynamic wing units, achieving flight through a combination of thruster power and lift. However, in mobile suit form its aerodynamic characteristics were extremely poor, and it was determined that it was unable to move freely in three dimensions. Thus the unit’s specifications were changed to the current concept of achieving flight through high thrust.
