During the Battle of Earth, John-117 was able to take the Covenant bomb from Firing Control by wrestling it from the hands of its Sangheili and Unggoy guards, moving it to Hanger C-01, and then activating the airlock door, explosively decompressing the bay. The Spartan was miraculously able to guide his trajectory to intersect with the damaged engine of a nearby unshielded Covenant CAS-class assault carrier. He then drifted away towards the UNSC In Amber Clad, destroying the Assault Carrier during his descent.
