On August 30, 2552, Knife 26 led a flight of four Longswords in escorting SPARTAN Red Team aboard Pelican Bravo 001. En route, Knife 26's flight was engaged by a dozen Seraph-class starfighters. Knife 26's pilot drew back and engaged the Seraphs to give Red Team enough time to get to the planet's surface. Knife 26 was presumably destroyed, as it lost radio contact with Bravo 001 seconds after it engaged the Seraphs.
