The main module of ZGMF-X56S Impulse Gundam's modular design, the Core Splendor's primary role is to serve as the cockpit of the Impulse Gundam. However, it can also transform into a fighter craft to provide tactical flexibility or as an escape system when the suit is badly damaged. It is armed with two nose-mounted MMI-GAU19 20mm machine guns, and two wing-mounted QF908 6-tube anti-air missile launchers that are loaded with several AGM33 "Ladybird" guided missiles, and although these are light armaments, they can nevertheless cause moderate damage to enemy units. The missile launchers will detach and return to the Minerva when the Core Splendor is docking with other modules to form the Impulse Gundam.
When ZAFT created the Impulse, they built the suit as a modular unit, capable of splitting into three different modules. The cockpit of the suit was located in the Core Splendor, a fighter craft which could operate on its own and serve as an escape system. This Core Splendor system was first tested on the ZGMF-X101S ZAKU Splendor, then adapted to the Impulse's design.
