Naval Action - Santa Ana
This is a premium consumable ship. It is not refundable.

Santa Ana
First rate ship of the line designed by a famous Spanish naval engineer Romero Landa. Santa Ana was launched in 1784 and the first sea trial indicated her almost perfect design - Santa Ana performed surprisingly well in heavy seas. The success of sea trials convinced the Admiralty to order several more ships of her design forming the Santa Ana class who later became the main force of the Spanish Navy. Santa Ana was a flagship in the battle of Trafalgar and after a fierce fight against a British flagship HMS Royal Sovereign was captured by the British Royal Navy and later recaptured back by Spanish ships sent on rescue.
