Begotten Angel

From Halopedia, the Halo wiki

Template:Stub-Starship The Begotten Angel was a command cruiser in the Covenant fleet. It was a relatively slow warship, but it is certainly the "most luxurious".

It has been conjecturalized to be a CCS-class battlecruiser, carrier, Assault Carrier, Supercarrier, or Supercruiser.
