Knife 26
From Halopedia, the Halo wiki
The UNSC ''Kunchandy'' is an immense UNSC supercarrier that as of yet, there is very little intel on. Recent data leaks have shown this ship to be of unimaginable proportions. The only hints to the existence of this ship have been leaks of beyond enormous allocations of supply's to an unknown ship yard outside the zones of the Oort Cloud.. Sources have hinted at the ship being well over 7 kilometers, dwarfing even the UNSC Infinity. Any more intel as of yet is unknown.
