Map - HMS Victory (HMS Victory)

HMS Victory is a 104-gun first-rate ship of the line of the Royal Navy, she is the world's oldest naval ship still in commission. With years' service as of 2023, ordered in 1758, laid down in 1759 and launched in 1765 - she is best known for her role as Lord Nelson's flagship at the Battle of Trafalgar on 21 October 1805.

She additionally served as Keppel's flagship at Ushant, Howe's flagship at Cape Spartel and Jervis's flagship at Cape St Vincent. After 1824, she was relegated to the role of harbour ship. In 1922, she was moved to a dry dock at Portsmouth, England, and preserved as a museum ship and she has been the flagship of the First Sea Lord since October 2012.

In December 1758, William Pitt the Elder, in his role as head of the British government, placed an order for the building of 12 ships, including a first-rate ship that would become Victory. During the 18th century, Victory was one of ten first-rate ships to be constructed. The outline plans were based on HMS Royal George (1756) which had been launched at Woolwich Dockyard in 1756, and the naval architect chosen to design the ship was Sir Thomas Slade who, at the time, was the Surveyor of the Navy. She was designed to carry at least 100 guns. The commissioner of Chatham Dockyard was instructed to prepare a dry dock for the construction. The Master Shipwright in charge of construction was Edward Allin, son of Sir Joseph Allin, former Surveyor of the Navy. The keel was laid on 23 July 1759 in the Old Single Dock (since renamed No. 2 Dock and now Victory Dock), and a name, Victory, was chosen in October 1760. In 1759, the Seven Years' War was going well for Britain; land victories had been won at Quebec and Minden and naval battles had been won at Lagos and Quiberon Bay. It was the Annus Mirabilis, or Wonderful Year, and the ship's name may have been chosen to commemorate the victories or it may have been chosen simply because out of the seven names shortlisted, Victory was the only one not in use. There were some doubts whether this was a suitable name since the previous HMS Victory (1737) had been lost with all hands in 1744.

A team of 150 workmen were assigned to construct Victory's frame. Around 6,000 trees were used in her construction, of which 90% were oak and the remainder elm, pine and fir, together with a small quantity of lignum vitae. The wood of the hull was held in place by six-foot copper bolts, supported by treenails for the smaller fittings. Once the ship's frame had been built, it was normal to cover it up and leave it for several months to allow the wood to dry out or "season". The end of the Seven Years' War meant that Victory remained in this condition for nearly three years, which helped her subsequent longevity. Work restarted in autumn 1763 and she was floated on 7 May 1765, having cost £63,176 and 3 shillings, the equivalent of £ today.

On the day of the launch, shipwright Hartly Larkin, designated "foreman afloat" for the event, suddenly realised that the ship might not fit through the dock gates. Measurements at first light confirmed his fears: the gates were at least 9½ inches too narrow. He told the news to his superior, master shipwright John Allin, who considered abandoning the launch. Larkin asked for the assistance of every available shipwright, and they hewed away enough wood from the gates with their adzes for the ship to pass safely through. However, the launch itself revealed significant problems in the ship's design, including a distinct list to starboard and a tendency to sit heavily in the water such that her lower deck gunports were only 4 ft above the waterline. The first of these problems was rectified after launch by increasing the ship's ballast to settle her upright on the keel. The second problem, regarding the siting of the lower gunports, could not be rectified. Instead it was noted in Victory's sailing instructions that these gunports would have to remain closed and unusable in rough weather. This had potential to limit Victory's firepower, though in practice none of her subsequent actions would be fought in rough seas.

Because there was no immediate use for her, she was placed in ordinary and moored in the River Medway. Internal fitting out continued over the next four years, and sea trials were completed in 1769, after which she was returned to her Medway berth. She remained there until France joined the American War of Independence in 1778. Victory was now placed in active service as part of a general mobilisation against the French threat. This included arming her with a full complement of smooth bore, cast iron cannon. Her weaponry was intended to be thirty 42-pounders (19 kg) on her lower deck, twenty-eight 24-pounder long guns (11 kg) on her middle deck, and thirty 12-pounders (5 kg) on her upper deck, together with twelve 6-pounders on her quarterdeck and forecastle. In May 1778, the 42-pounders were replaced by 32-pounders (15 kg), but the 42-pounders were reinstated in April 1779; however, there were insufficient 42-pounders available and these were replaced with 32-pounder cannon once again.
