HMS Warrior is considered to be, an important milestone, in terms of the development of modern warships - as Warrior featured the iron of the then-to-be future, whilst retaining her Victorian roots:
Warrior's iron hull form, was designed to repel the cannon balls, of an enemy fleet. This was achieved, through the concept of an armoured citadel - as Warrior's thirty-eight 68-pounder guns/cannons, were protected behind an 'iron wall', that was 4.5 inches thick. This meant, that Warrior could engage, enemy ships of the line (who at this time, featured: wooden hull forms, and usually 32-pounder guns/cannons), without fear of her own armoured belt, being penetrated. This gave the Royal Navy, an undeniable advantage, when it came to naval conflict - as warships would sit in a line, firing at each other, and the warships made of wood, would sink first! In any case, Warrior retained the Admiral's Day/Night Cabin (at her stern), as was installed on HMS Victory (though Warrior's, was on a less grander scale). This featured: decorated windows, with golden patterns in the wood/iron, bordered with white - to reflect the rank of the most important officer on the warship, the Admiral (or Captain).
HMS Warrior was not-so-unique, in terms of her sails and rigging - as she was a fully rigged, ship of the line (like HMS Victory), that could harness the power of the wind:
Warrior's sails were used to push her through, the World's oceans and seas (but could also augment the power of her steam engine). Whilst only five sails are illustrated here, we shall use them to define the sails and masts, of a fully rigged ship. From bow to stern, bottom to top: i) Jib. This was rigged, between the Bowsprit and the Foremast. ii) Fore Topsail. This was at the level of the Fore Topmast (above the Fore Lowermast). iii) Fore Royal Sail. This was at the level of the Fore Royal Mast (above the Fore Topgallant Mast). iv) Main Topgallant Sail. This was at the level of the Main Topgallant Mast (above the Main Topmast). v) Spanker. This was attached with two spars, to the Mizzen Lowermast (the aftermost lowest mast). Warrior's rigging, was used primarily, to hold both her masts and sails in place (called standing rigging and running rigging, respectively) - but also had secondary functions, such as: making adjustments to the sails (to capture more/less wind), and for gaining access to, various higher-level mast platforms (as used by her lookouts). Her rigging, involved the use of ropes and blocks (containing one or more pulleys) - whose operation, was an art in itself!
HMS Warrior is considered to be 'one of the first' true ironclads (if not indeed the first) - as she was equipped with a hull form, that was made entirely of iron:
Warrior's hull form, made use of iron, both internally (such as in her bulkheads and frames) and externally (such as in her 4.5 inch thick belt armour). For 1860, this was a marvellous achievement - as all preceding warships, had only ever been constructed, with wooden hull forms (including their bulkheads, frames and armour). Despite this, Warrior still needed to be based upon the warships of the past (such as HMS Victory) - so Warrior's hull from, was essentially a wooden design, that was constructed in iron! As such, it was expected that her manoeuvrability, would be similar to that of previous ships of the line - so she retained their clipper bow (which improved her sea keeping).
HMS Warrior is considered to be 'rather unique' as a warship - as she was equipped with both sails, and a steam engine (that was fuelled by coal):
This meant that she could navigate the oceans of the World, using one of three modes: i) just her sails. ii) just her steam engine. iii) both her sails and her steam engine - when speed was of the essence! Her sails, though retained from the days of HMS Victory (1803), also meant that Warrior had a useful fallback, in the event that she run out of coal. Despite this, her steam engine was connected to a single propeller, which could be regarded as the grandfather of all modern ship propellers (because it was of a simpler design - with only two blades). In any case, Warrior's propeller was designed, to push her 9000 tons, through the sea lanes of the British Empire.
