Designated as a 5th generation Gundam, the Gundam Harute is the latest in Celestial Being's line of transformable mobile suits. Harute's overall design is derived from the combined technical and combat data of GN-007 Arios Gundam, GNR-101A GN Archer and GNR-010/XN XN Raiser. Because Celestial Being no longer had the resources it used to develop brand new units, they decided not to design a new unit and instead based Harute directly from Arios's and GN Archer's development platforms (recycling its predecessors' MS frame design); however, due to upgrades in new equipment and weapons, Harute's capabilities are significantly greater over its predecessor.

One of the most unique features of Harute is its cockpit. It is more compact than Arios', but made to be utilized by two pilots. It's a two-seat cockpit control system, the first of its kind amongst Gundams. The cockpit controls are delegated between Soma and Allelujah. The controls are built similar to 21st century fighter cockpits, both seats have helm controls for co-use and support. While Allelujah focuses on aerial combat tactics, Soma focuses on weapons and systems control.
