Unlike other Starfleet ships designed for exploration with defense as a secondary concern, the Cerberus is primarily a warship. While it resembles the experimental (and slightly larger) U.S.S. Prometheus, the Starfleet Corps of Engineers chose not to include the multi-vector assault mode on the Cerberus. That doesn’t mean it’s not an impressive warship, however; it is intended to battle larger ships like the Klingon Vo'Quv.
