HMS Princess was a 70-gun third rate ship of the line of the Royal Navy, notable for its impressive size and design. Built in 1730 at the shipyard of El Astillero in Guarnizo, Cantabria, she was originally constructed for the Spanish Navy and served as Princesa. Her armament comprised 70 guns distributed across different calibers: 26 × 24-pounders, 28 × 18-pounders, and 16 × 8-pounders. The vessel was distinguished by her high build and large size, which allowed her to carry unusually large guns, many of which were brass, and to open her lower gunports in conditions where other ships could not. In 1740, she was captured off Cape Finisterre after a fierce engagement with a British squadron. Despite losing a mast and suffering heavy casualties—70 killed and 80 wounded—the Princesa inflicted significant damage on her pursuers before ultimately surrendering. The British acquired her in Portsmouth, where she was repaired and refitted at a cost of over £36,000. Her design and fighting qualities drew considerable interest, and her size and firepower influenced subsequent British warship development. During her service with the Royal Navy, HMS Princess participated in several key operations during the War of the Austrian Succession, including the Battle of Toulon in 1744 and various operations in the Mediterranean, Caribbean, and off North America. She served under multiple commanders, often as a flagship, and was active in both fleet actions and patrols. Notably, she was also engaged in operations off Lorient and took part in expeditions to Louisbourg. After her active service, she was laid up and assessed as unfit for further combat. From 1759 onward, she was converted into a hulk at Portsmouth—a role she held through the Seven Years' War and the American War of Independence. HMS Princess remained in service as a hulk until she was sold for breaking up in 1784, marking a career spanning 44 years in the British Royal Navy. Her capture, design, and lengthy service record underscore her maritime significance during a transformative period in naval history.
