ZGMF-56S Impulse Gundam
ZAFT's newest Gundam. Relies on batteries instead of nuclear power. Since its energy can be replenished from a long distance by its mothership, the PS (Phase Shift) armor can operate a lot longer. The cockpit area can transformed into a fighter called the Core Splender. The Impulse can be broken up into 3 separate units. Like the Strike Gundam, the Impulse can be further equipped with 3 different packs (or mode). It is called the Force Impulse Gundam (ZGMF-X56S/α) when it's in the aile-mode. Additionally, the backpack systems are referred to as "Silhouettes", with the one pictured known as the "Force Silhouette".
