HMS Rupert was a notable 64-gun third rate ship of the line in the Royal Navy, launched at Harwich Dockyard on 26 January 1666. Constructed as part of the 1664 shipbuilding programme, she was regarded as an impressive vessel, with Samuel Pepys noting in his diary a conversation with her designer, Anthony Deane, who claimed she was "the best ship that was ever built" and praised his ability to predict her draught of water before launch. Originally, HMS Rupert carried a complement of approximately 400 men and was armed with 66 guns, including twenty-six 24-pounders, twenty-four 12-pounders, fourteen sakers (5-pounders), and two 3-pounders. By 1685, her armament was slightly reduced to 64 guns, maintaining a similar composition. She played a significant role in naval engagements, notably on 1 April 1678, under Commodore Arthur Herbert. During this action, she engaged the Algerine warship Tiger alone, which was heavily defended with forty guns and 400 men. Rupert's engagement was fierce; she inflicted severe damage, and her captain Herbert sustained an eye injury, with heavy casualties among officers and crew, demonstrating her combat importance. In the late 17th and early 18th centuries, HMS Rupert underwent extensive rebuilding. In 1697, she was taken into Plymouth Dockyard for reconstruction by Benjamin Rosewell, resulting in her relaunch in November 1703 as a 66-gun third rate. Later, in 1716, she was reduced to a fourth rate. Further rebuilding occurred after she was ordered to be taken to pieces in 1736; she was reconstructed at Sheerness Dockyard and relaunched on 27 October 1740 as a 60-gun fourth rate ship, built according to the 1733 proposals of the 1719 Establishment. HMS Rupert served for over a century, witnessing significant naval developments, before being broken up in 1769. Her long service life and multiple rebuildings exemplify the evolving practices of ship design and naval strategy in the Age of Sail, marking her as a vessel of maritime historical significance.
