Typhoon consisted of two Lambda-class T-4a shuttles of the Rebel alliance. These shuttles, collaborating with shuttle groups known as Thunder and Lightning, participated in the initial stage of Operation Grain Snatch. The mission assigned to them was to seize the Y-wing starfighters that were escorting Overlord Ghorin's CR90 corvette, the [Halifax], which was transporting grain intended for the Empire. Keyan Farlander successfully incapacitated all the Y-wings, and subsequently, the shuttles secured them. This capture was orchestrated to undermine Ghorin's reputation.
