ike its predecessor, the Ex-S Gundam was also capable of transforming into a waverider mode of sorts, but unlike the S Gundam, which divided into three separate components, the Ex-S Gundam changes into one large unit called the G-Cruiser. For its size, the G-Cruiser was incredibly fast and used for travelling over a great distance in a short amount of time. To conserve the fuel of the Ex-S Gundam for use in combat situations, the G-Cruiser had two large propellant tanks mounted in the front over the Ex-S Gundam's shoulders. These extra fuel tanks would be jettisoned when the G-Cruiser reaches the battlefield and transforms into the Ex-S Gundam.
