The Punic-class supercarrier is a heavy warship sub-classification (of carrier) within the UNSC Navy. There were only a few constructed, with only one known hull being completed which is the UNSC Trafalgar. However, due to the size of the Navy during the Human-Covenant war, it is likely that there were a few supercarrier-type ships in service. The supercarrier was made for direct confrontation with Covenant capital ships, and were one of the only UNSC ships effective in this role.
