Constructed under the auspices of Prince Schneizel El Britannia, the IFX-V301 Gawain was a highly unusual Knightmare Frame. Larger and heavier than practically every Knightmare produced up to that point, the Gawain featured many experimental technologies, most of which were incomplete at the time of its first deployment. Instead of the ejection block cockpit standard to Britannian Knightmares, the Gawain featured a two-seater cockpit, though only one pilot was needed to operate the machine. As a result of its unorthodox design, it remained unknown if the Gawain even featured such standard Knightmare technologies as the factsphere sensor camera. What it did include was the advanced tactical computer called the Druid system, the flight-capable Float system, and the powerful but uncontrollable hadron cannons. Initially, Schneizel planned on using the Gawain's Druid system to analyze the mysterious ruins found on Kaminejima Island, but his plans were disrupted when Zero and Kallen Stadtfeld of the Order of the Black Knights stolethe Gawain in order to escape from the Britannians.
After returning to base, Zero had the Order's resident scientist Rakshata Chawla install a Gefjun Disturber, which regulated the hadron cannons' power as well as providing the Gawain with a degree of stealth. The Gawain became Zero's personal Knightmare, co-piloted by his partner C.C., the only Black Knight to know Zero's true identity as Lelouch Lamperouge. During the Black Rebellion, Lelouch came under fire from Jeremiah Gottwald, enhanced by Britannia's Code R project and piloting the experimental FXF-503Y Siegfried. In order to deal with the threat and allow Lelouch to rescue his abducted sister, C.C. piloted the Gawain solo and grappled with the Siegfried, pushing both machines to the bottom of the ocean. Over a year later, the Black Knights recovered the ruined Gawain, and Rakshata used whatever components she could recover to build the Black Knights' airship Ikaruga, as well as a new knightmare for Zero, the Type-0/0A Shinkirou.
