They have tremendously thick hull armor and can engage targets from fairly long range and are surprisingly fast and agile for their size. Currently, these ships have only appeared as part of Treasure Fleets and have no permanent patrol routes.
The HMS Invincible, like all other Treasure Fleet ships, uses powerful Explosive deck guns, this makes her a highly dangerous ship, perhaps even the strongest enemy ship at sea.
- The name of this ship seems to come from its real live counterpart, the Invincible, a massive French Navy Ship Of The Line which was captured by the British Royal Navy in 1747 and renamed HMS Invincible. The HMS Invincible was one of the first 74-gun Ship Of The Line in the Royal Navy. At the First Battle of Cape Finisterre, while still held by the French, she alone attacked 6 British warships to let the convoy she was escorting to escape. HMS Invincible sank after hitting a sandbank in the East Solent. Her wreck is still viewable today.
