History
In late CE 73, ZAFT created a new series of advanced mobile suits to succeed their previous generation of Gundams, which were all lost in the previous war. Since the Treaty of Junius banned the military use of the Neutron Jammer Canceller, these new Gundams use conventional battery power instead. However, technological improvements over the last two years mean that battery efficiency is improved. One of these new suits was the Impulse, a multi-role unit similar in concept to the Earth Alliance's old Strike. The Impulse was designed simultaneously with ZAFT's new battleship Minerva, which includes a catapult exclusive to its use. Using this smaller catapult, the Impulse launches with its modules divided, while combining in flight.

The idea behind Impulse was based on how many battles in the first war were weight greatly by skill of single ace pilot. By building a MS that can perform various roles, it's possible to let single ace pilots to operate in many different situations. In addition to standard Silhouete Pack, more packs are design to allow Impulse to operate in specify role. One of them is the ε Abyss Silhouette, which focus on aquatic combat by utilizing high speed MA form. However, the developers figure out that Abyss Silhouette isn't very effective for its purpose. Thus the plans was scraped and redesign into separate MS, the ZGMF-X31S Abyss.
