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).
