Heavy Combat Cruisers, often simply called Heavy Cruisers, are the most powerful warships in any faction before Capital Ships. They are very well armed and quite durable. They sometimes form the backbone of late game fleets and can easily defeat any other non-capital ship in single combat, although are very vulnerable to Bombers.
