Importance I was surprised to see Warrior listed as mid importance As arguably the most important ship of the 19th century she deserves a top or at least a high importance rating Here are some of her claims to fame First British ironclad Second ironclad in the world First successful iron hulled warship Broke the record for largest warship when completed Revolutionary design and construction Revolutionary armament scheme Oldest surviving ironclad Only surviving major fleet unit from the ironclad period The 19th century might be a neglected period of maritime history but Warrrior is one of the most important ships of the century
