Editing Battle of Navarino (section)

====Allies====
The Allied navies at this time were still deploying essentially the same technology as during the Napoleonic Wars: sailing ships, unarmoured wooden hulls and [[muzzle-loading]] [[smoothbore]] [[cannon]]. The navies, especially the British one, had ignored the new technologies that were to transform them by the 1850s: [[steam propulsion]], [[ironclad|ironclad hulls]], [[rifling|rifled guns]] and [[shell (projectile)|explosive shells]]. All these had been invented by 1827, but their development for naval warfare, let alone introduction, met dogged resistance from senior naval echelons. In the words of one scholar: "The great admirals of the 18th century would have had no difficulty in taking over Codrington's command at short notice."<ref name="Woodhouse 1965 28">Woodhouse (1965) 28</ref>

However, the Royal Navy's warships had seen some improvements. Ships with triple gun-decks such as [[Horatio Nelson|Nelson]]'s famous {{HMS|Victory}} had been phased out. Triple-deckers had been found to be too unstable and difficult to manoeuvre. The standard {{sclass|Canopus|ship of the line|0}} was a double-deck 74–84 ship of the line, based on the successful "[[Seventy-four (ship)|74]]" French design. In addition, gun-calibres had been upgraded. The Napoleonic-era {{sclass|Fame|ship of the line|0}} had been equipped with 32-pounders on the main gun-deck, 18-pounders on the upper deck and 9- and 12-pounders on the super-structures (quarterdeck and forecastle). In contrast, the guns were now all 24- or 32-pounders (plus a couple of massive 68-pounder [[carronades]] on the super-structures). [[Frigates]] were either double-deckers of 50–60 guns (known as large frigates) or single-deckers with 24–44 guns.<ref name="Woodhouse 1965 28"/>

Most of the Allied ships, however, were still veteran Napoleonic-era warhorses (e.g. {{HMS|Albion|1802|6}}). Codrington's only ''Canopus''-class was his flagship, {{HMS|Asia|1824|6}} (launched 1824), although ''Genoa'' (an impounded French "74") was also post-Napoleonic (1816). In the French squadron, Rigny was so appalled by the state of the three ships of the line sent to him that he decided to keep his flag on the ''Sirène'', a modern frigate.<ref>Woodhouse (1965) 70</ref>
