HMS Newcastle was a 50-gun fourth-rate warship of the Royal Navy, constructed during the Napoleonic Wars with an innovative design in response to emerging American spar-decked frigates. Ordered on 6 May 1813 from Wigram, Wells & Green, she was laid down in June 1813 and rapidly built of pitch pine and softwood, to expedite her entry into service. Launched on 10 November 1813, she was completed at Woolwich Dockyard by 23 March 1814. Her design, attributed to émigré designer Jean-Louis Barrallier, featured a spar-deck with thirty 24-pounders on her main deck, twenty-four 42-pounder carronades on her spar deck, and four 24-pounders on her forecastle, making her a formidable vessel for her time. Initially commissioned under Captain George Collier in November 1813, her command soon transferred to Captain Lord George Stuart. As a large spar-decked frigate, Newcastle was built partly in response to the heavy American frigates like USS Constitution. She served notably during the War of 1812 and the Napoleonic Wars, operating in squadron formations that sought to hunt American frigates; however, she was unable to intercept them before the war concluded. Her notable service included sharing in the capture of the American privateer Prince de Neufchatel on 28 December 1814, and participating in the pursuit of USS Constitution, during which she contributed to the capture of the sloop Levant after Constitution eluded the British squadron. Throughout her service, Newcastle was adapted for flag officer use, featuring accommodation for flag officers and a poop deck built over the quarterdeck. She was re-rated as a 60-gun fourth rate in February 1817. After the war, she spent time as the flagship on the North American Station. Paid off in 1822, she was converted into a lazarette in 1824, serving as a quarantine and hospital ship, and remained in this role until her sale in 1850 to John Brown for breaking up. Her career highlights her role as a significant example of early 19th-century naval innovation and adaptation during a pivotal era of maritime warfare.
