The construction of Victorian fortifications for the protection of our U.K. harbours arose from the fear of invasion due to politcal and military developments in France. The first panic came in 1844 due partly to the increase in the French Naval budget. The second was due to the re-election of Louis- Napoleon in 1851-2 and the third came in 1859 due to French political interventionism and military sucess in Italy combined with advances in French naval technology including the launch of the iron-clad Gloire. The United Kingdom's defences were suffering from forty years of neglect when General Sir Fox Gurgoyne brought out a paper entitled ' Observations on the possible Results of a War with France under our present System of Military Preparation'. In it he argued that the French might obtain temporary naval superiority in the Channel long enough to stage an invasion of our shores in great force and concluded that they would succeed, given the current level of defence.
This had an impact on Lord Palmerston who brought out his own paper called 'The Defences of the Country' in 1846. The developments of steam-driven ships, armour-plate, rifled artillery and lesson learned from the Crimean War all fueled public debate. In 1855 Burgoyne produced a 'Memorandum on the probable effect of the Rifled Cannon on the Attack and Defence of Fortifications'. The first 'panic' of 1844 led to the fortification of Milford Haven and the improvement of the batteries defending Portsmouth Harbour. The second panic on 1852 led to the fortification of the western approaches to Portsmouth and The Solent. This included the batteries at Browndown and Stokes Bay with the two forts Gomer and Elson that became the Gosport Advanced Line. In 1855 Burgoyne published a 'Memorandum on the General Principles of Standing Defences suggested for Great Britain'. which contained arguments for and against defending Spithead with sea-forts. Jervois, the assistant to Burgoyne was charged with preparing detailed proposals for the defence of Plymouth and Portsmouth in 1857. The following year he published a 'Memorandum relative to the Protection of Dockyards and most important Harbours of England' and another on 'Defence of the Country against Invasion'. In 1859 he published another paper in which he considered the impact of the new Armstrong rifled guns on the defences of Portsmouth. Yet another memorandum along the same lines was produced by Burgoyne and so the Goverment set up a Royal Commission to consider the defences of the United Kingdom, reporting back in 1860. It formed a special committee to consider the defences of Spithead which included eight naval officers, one of whom was Captain Cowper Coles.The Commission concluded that ' We are led to the opinion that neither our fleet, our standing army, nor our volunteer forces, not even the three combined, can be relied on as sufficient against foreign invasion'. The Commision saw fortification as the most economical solution, the 'Protection of the dockyards against attack by sea, is obviously the first point of consideration'. Some opponents thought that the forts would not be able to stop the passage of a hostile fleet and favoured the addition of armour plate to ships to be the solution. Burgoyne however did not agree 'I have no great confidence in iron-plated vessels. I think that improvements in artillery will go faster than improvements in fortifying the sides of ships.'
Now began the debate. Which was best for defending the U.K.? Forts or ships? Some extremists of the so called 'Blue Water School' postulated that fortifications were unecessary and the defence of the U.K. should be left entirely to the Navy. Coles realised that the forts were not intended to be a substitution for a strong Navy and were primarily for the protection of dockyards and naval bases to allow the fleet freedom of movement and action. The debate on the value of the sea-forts and the issue of ships versus forts became contentious. Coles of the Blue Water School was an influential voice producing a paper 'Our National Defences' in 1861. He dominated the argument in favour of a strong navy including the use of centre-line iron revolving turrets on warships. He was a very vociferous opponent of the Spithead forts but he held some strong views on the defence of our coasts and his ideas on this were eventually adopted. He accepted that fortifications were necessary and he applied his ideas on turrets and sheilded guns to both ships and forts.
The launching of the steam powered iron-clad warship 'Glore' by the French in 1859 was matched by the British iron-hulled 'Warrior' in 1860. Thus began a revolution in ship design and the Royal Navy rapidly became one of the most powerful sea forces in existence.
In 1861 the broadside ironclad Black Prince followed swiftly by Defence and Resistance were launched. These were followed by Hector, Ocean, Royal Oak and Caledonia 1862, with Valiant, Achilles, and Minotaur in 1863. In 1864 Royal Alfred, Enterprise, Favourite, Zealous and Lord Clyde were launched.
In 1864 the Royal Sovereign, laid down in 1857, was converted to a turret ship.
In 1865 Pallas, Bellerophon and Agincourt were launched followed by Lord Warden.
In 1867 Penelope was launched. In 1868 the Central Battery Ironclad Repulse was launched, then Hercules and Monarch followed by the Turret ship Cerberus in 1868. (Cerberus still exists: http://www.cerberus.com.au/)
The turret ship first appeared in conflict when USS Monitor steamed into Battle. It was designed by the Sedish engineer Ericson. Captian Cowper Coles was a keen exponent of the Turret ship and he began designing ships armed with central turrets for the Royal Navy. Coles' Turrets turned on a ring of bearings which he thought superior to the central spindle of Monitor. The first Royal Naval ship to carry her main armament in turrets was H.M.S. Prince Albert, launched in 1864. The turret ship HMS Captain, launched 1869 capsized in a gale 1870. Inflexible was an improvement as it had two turrets either side of the centre line allowing both to fire fore, aft and broadside.
The first such vessel was Hotspur (1864) then Rupert (1970), Conqueror (1879) and Hero (1884) The vessels Sanspareil and her sister Victoria were the final expression of the so called single turret ship. The wreck of H.M.S.Victoria has recently been discovered, Tripoli Lebanon 2008.: Youtube video.

The Royal Navy's first Torpedo boat, HMS Vesuvius, was launched in 1874 followed by the the series of torpedo boats starting with HMS Lightning in 1876, the first seagoing vessel to be armed with self-propelled Whitehead torpedoes. Torpedo RamsPolyphemus was launched in 1882. Next came the torpedo cruisers of the Scout and Archer class with the emphasis on topedo attack. In the mid-1880s the focus shifted to torpedo-catchers and the first torpedo gun boats such as HMS Rattlesnake in 1886. This was followed by the Sharpshooter, Jason and Dryad classes.
Explosive torpedoes became common place in Naval warfare resulting in a need for fast Torpedo Boat Destroyers and Torpedo Depot Ships. In 1892 Fisher was asked to look at the future of fast and powerful vessels capable of catching and destroying torpedo boats.
The two Daring Class Destroyers, Daring and Decoy, were the very first torpedo boat destroyers ordered for the Navy, built by Thornycroft. Another two, Havock and Hornet were built by Yarrow. Two more followed, Ferret and Lynx, all six being designated as the '26-knotters' (1892-1893). In 1894 the '30-kontters' followed, Desperate, Fame, Foam and then Mallard. Added to this were Quail, Sparrowhawk, Thrasher and Virago.
The Class C Topedo Boat (designated in 1913) Destroyers were built in the 1890s as individual designs meeting Admiralty specifications. All had three funnels with a turtle-back forecastle. They had a top speed of 30knots.
With the advent of the steam-propelled ironclad warships came a new weapon of special potentiality, the ram. Due to the vulnerability of the ironclad to damage below the waterline all of the early ironclads from Warrior onwards were fitted with the ram.. After the American Civil War battle of Lissa in which the Italian flag-ship was sunk by one blow from the ram of the Austrian ironclad, both England and France constructed vessels specially for the purpose of ramming. The Rupert and the Hotspur were built with a single turret facing forward to be used in end-on fighting, clearing the way for the attacking ship by firing heavy projectiles before it rammed. The Admiralty were then persuaded to build a special ship without heavy guns, a strange class of Protected Torpedo Boat with shallow draft and low profile designed with the secondary purpose of sinking enemy ships at anchor, the Polyphemus. It was begun in 1878 and completed in 1882 with a powerful ram prow and five torpedo tubes. Its low profile afforded a small mark for enemy fire whilst its turtleback shape gave protection from light gun projectiles. Its top speed of 17 to 18 knots aided its ramming capability.

By the 1880s the term Ironclad was dropped and the new ships were constructed to a standard pattern. They were classed as Protected Cruisers or Battleships.

Pre-dreadnought was the general term applied to all battleships built prior to the Dreadnought Class of 1905.
They replaced the ironclads of the 1870-1880 period and were armed with main armament of heavy guns in turrets and secondary armament of lighter guns.
