HMS Victory is a 104-gun first-rate wooden sailing ship of the line. With 248 years of service as of 2026, she is the world's oldest naval vessel still in commission. She was ordered for the Royal Navy in 1758, during the Seven Years' War, and laid down in 1759. That year saw British victories at Quebec, Minden, Lagos and Quiberon Bay and these may have influenced the choice of name when it was selected in October the following year. In particular, the action in Quiberon Bay had a profound effect on the course of the war; severely weakening the French Navy and shifting its focus away from the sea. There was therefore no urgency to complete the ship and the signing of the Treaty of Paris in February 1763 meant that when Victory was finally floated out in 1765, she was placed in ordinary. Her construction had taken 6,000 trees, 90% of them oak.
The Mary Rose was a carrack in the English Tudor navy of King Henry VIII. She was launched in 1511 and served for 34 years in several wars against France, Scotland, and Brittany. After being substantially rebuilt in 1536, she saw her last action on 19 July 1545. She led the attack on the galleys of a French invasion fleet, but sank off Spithead in the Solent, the strait north of the Isle of Wight.

HMS Warrior is a 40-gun steam-powered armoured frigate built for the Royal Navy in 1859–1861. She was the name ship of the Warrior-class ironclads. Warrior and her sister ship HMS Black Prince were the first armour-plated, iron-hulled warships, and were built in response to France's launching in 1859 of the first ocean-going ironclad warship, the wooden-hulled Gloire. Warrior conducted a publicity tour of Great Britain in 1863 and spent her active career with the Channel Squadron. Obsolescent following the 1873 commissioning of the mastless and more capable HMS Devastation, she was placed in reserve in 1875, and was "paid off" – decommissioned – in 1883.

HMS Royal George was a 100-gun first-rate ship of the line of the Royal Navy. She was the largest warship in the world at the time of her launch on 18 February 1756. Royal George took ten years to construct at Woolwich Dockyard. The ship saw immediate service during the Seven Years' War, including the Raid on Rochefort in 1757. She was Admiral Sir Edward Hawke's flagship at the Battle of Quiberon Bay in 1759. The ship was laid up following the conclusion of the war in 1763, but was reactivated in 1777 for the American Revolutionary War. She then served as Rear Admiral Robert Digby's flagship at the Battle of Cape St Vincent in 1780.
Southsea Castle, historically also known as Chaderton Castle, South Castle and Portsea Castle, is an artillery fort originally constructed by Henry VIII on Portsea Island, Hampshire, in 1544. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and defended the Solent and the eastern approach to Portsmouth. The castle had a square central keep, two rectangular gun platforms to the east and west, and two angled bastions to the front and rear, and was an early English example of the trace italienne-style of fortification popular on the Continent. The Cowdray engraving of the Battle of the Solent in 1545 depicted Henry VIII visiting the castle. Despite several serious fires, it remained in service and saw brief action at the start of the English Civil War in 1642 when it was stormed by Parliamentary forces.
