The HMS Dover was a notable 40-gun fourth-rate frigate built for the Commonwealth of England's navy and launched in January 1654 at Shoreham by shipbuilder William Castle. Constructed as a ship of the line, Dover's dimensions and specific design details are not provided, but her armament classification indicates a vessel designed for versatile combat roles during the mid-17th century. Following the Restoration in 1660, she was incorporated into the Royal Navy and renamed HMS Dover. By 1665, her firepower had been increased to 46 guns, including culverins, demi-culverins, and sakers, reflecting her evolving role in naval engagements. Her armament was further augmented in 1666 with an additional six demi-culverins, bringing her to a total of 52 guns, which signifies her importance as a formidable warship in the fleet. HMS Dover participated in several significant naval battles during the Second Anglo-Dutch War, notably the Battle of Lowestoft (1665), the Four Days' Battle (1666), and the St James' Day Fight (1666). She also played a key role at the Battle of Solebay in 1672 under the command of John Ernle, where she notably saved Sir John Harman and the flagship Charles from a fire ship attack, highlighting her tactical importance and resilience. In 1694–95, HMS Dover was rebuilt at Portsmouth Dockyard and relaunched as a 48-gun fourth-rate ship of the line on 21 December 1695. Subsequently, she was reduced to a fifth-rate vessel with 40 guns per an Admiralty Order in 1716. Between December 1716 and July 1718, she underwent a extensive Great Repair at Deptford Dockyard, although she was not rebuilt again. The vessel was eventually paid off in July 1730 and dismantled in December of that year, marking the end of her service life. HMS Dover's operational history underscores her role in 17th-century naval warfare and her adaptability through rebuilds and refits, making her a significant vessel of her era.
