"So the HMS Warrior (the iron clad) could be considered the first 'dreadnought'?"
Ack-Ack, you're being a tease.

Watch it, I'm an ol' Turk'ead and well-versed in the art of the wind-up.
Strictly speaking, an ironclad is any vessel clad in iron; in the naval world the term is applied to an armoured ship.
Warrior was originally an iron ship, clad in iron armour backed by teak, the total weight of armour including the teak backing weighing 1,354 tons. As restored, she's afloat and moored alongside a purpose-built jetty in Portsmouth Harbour. A full-sized replica Penn trunk engine is installed and the boiler room is restored but the boiler fronts themselves are facades only, rather like an old Western town.
H.M.S.
Dreadnought was the world's first 'all-big guns' fast battleship. She was built in Portsmouth Dockyard and turned the naval world on its head by rendering all other battleships instantly obsolete when she was launched in 1906.
I'll be happy to show you around the Historic Portsmouth Dockyard any time you're over here, folks. Take a trip on the ferry across the harbour to my birthplace Gosport and visit the Submarine Museum while you're at it; H.M.S.
Alliance is looking a little weathered these days but she's the last conventional boat we've got and well worth a look-over, as is the rest of the exhibition (which includes the first RN submarine, the U.S.-designed
Holland I).
Re: CV-6
Enterprise, there was never a ship that served her country better but at least scrapping her freed her name for application to a new nuclear-powered flat-top. She deserved a better fate, perhaps, but nothing lasts for ever, not even the mountains . . .
