In the anime series Gundam Seed Destiny, the GAT-04 Windam is a newly introduced mass production mobile suit, intended to replace the GAT-02L2 Dagger L. Like its predecessor, the Windam is derived from the GAT-X105 Strike Gundam, and is capable of mounting various Striker Packs to adapt to different missions and enviroments. Among these are the AQM/E-A4E1 Jet Striker, which gives the Windam atmospheric flight capability, and a Striker Pack mounting two large nuclear missile launchers over its shoulders. Its normal weaponry includes a larger and more powerful beam rifle than the Dagger L's, two "Stiletto" armor penetrators, and two beam sabers, along with the regular 12.5mm CIWS.

The Windam was introduced in 73 CE, when a squad equipped with nuclear Strikers was sent to destroy PLANT. However, they and their supporting fleet were all destroyed by ZAFT's Neutron Stampeder. Soon afterward, Windams equipped with the Jet Striker were deployed to oppose ZAFT's "Operation Spear of Twilight", in which large numbers of mobile suits were dropped to Earth reinforce their Carpentaria and Gibraltar bases. Windams were also employed in a failed attempt to destroy ZAFT's battleship Minerva as it left Orb territorial waters, and again in the Indian Ocean.

Neo Lorrnoke, commander of the 81st Independent Mobile Battalion, pilots a custom Windam with a unique purple and dark gray color scheme, operating from the carrier John Paul Jones.
