Ark Royal was an English galleon, originally ordered for Sir Walter Raleigh and later purchased by the crown for service in the Royal Navy. She was used as the English flagship in a number of engagements, including the battles that resulted in the defeat of the Spanish Armada, and had a long career spanning over 50 years. Her fame led to a number of later warships of the Royal Navy being named Ark Royal in her honour, including a number of flagships of the fleet.
