UNSC Swift Justice
From Halopedia, the Halo wiki
The Swift Justice is long and blocky, with a bifurcated bow and a squat command deck atop its back.
On December 6, 2553, the Swift Justice responded to an attack on the UNSC passenger schooner Donoma, where it was found void of any survivors. The frigate was still present at the location of the attack two days later, having dispatched personnel to investigate the scene.
