The Princesa was a 70-gun ship of the line constructed for the Spanish Navy, representing a significant class of naval warfare vessels in the mid-18th century. Laid down on 11 May 1748 and launched on 15 September 1750, she was built in Havana according to specifications designed by Ciprian Autran and overseen by Pedro de Torres. Her construction was part of a naval expansion program, and she was one of three sister ships, alongside Infante and Galicia, commissioned simultaneously and delivered to the fleet on 15 August 1751. Following her commissioning, Princesa departed Havana on 1 March 1752 alongside her sister ships and the 80-gun ship Rayo, forming a squadron commanded by Francisco Ponce de Leon. The squadron arrived at Cádiz on 30 April of that year, marking her entry into active service within the Spanish fleet. Princesa’s most notable engagement was at the Battle of Cape St. Vincent on 16 January 1780, during which she was captured by a Royal Navy squadron commanded by Admiral George Rodney. Her capture marked a significant event in her service history, transitioning her from Spanish to British control. Recommissioned in England as the third-rate HMS Princessa, she participated in notable battles, including serving as the flagship of the Blue squadron at the Battle of the Saintes on 12 April 1782 under Admiral Francis Samuel Drake. After her active service, Princessa was employed as a sheer hulk starting in 1784, a role in which she was used as a stationary support vessel. Her maritime career concluded when she was broken up in 1809. The vessel’s history reflects the naval conflicts of the late 18th century and highlights her transition from a Spanish warship to a British auxiliary vessel, illustrating her role in the broader context of European naval warfare of her era.
