Capital ship

"Our fighters are mopping up the last of their recon picket now, nothing serious. But I've isolated approach signatures from multiple CCS-class battle groups, make it three capital ships per group. And in about 90 seconds they'll be all over us."

- Cortana

As an example: the large and heavily armed Phoenix-class is considered a support vessel in the UNSC, while the, which is nearly half its size, is considered a capital ship.
