UNSC Stalingrad

The UNSC Stalingrad was a UNSC Carrier in 2552. It was commanded by Admiral Carl "Buster" Patterson.

It was the flagship of a small task force sent to Onyx to retrieve Dr. Catherine Halsey and her Spartan-IIs and Spartan-IIIs. During the Battle of Onyx, the ship survived the first and second attacks on the Covenant fleet, but was destroyed when overwhelming Covenant reinforcements arrived from Slipspace.
