Sheer crap. . . .
HMS warrior was the first Ironhulled warship. An Englishmans research inspired the V rocket program and without an internal combustion engine none of you would have any cars.
Now get back onto education before the admin hat comes off and my mr frown hat goes on.
Iron hulled and ironclad are not the same thing. Iron hulls were not at all unusual by that point in history, but they were not armor, just a wrapper to keep the water out.
Warrior is usually described as the first ironclad, but nobody's ever going to remember
Warrior for its service history, unlike the
Merrimack/
Virginia. There is much to be said for proving the concept.
And the lineage of HMS
Dreadnaught and pretty much every warship from the late 1800s until the ship-to-ship missile killed the gunship be traced more or less directly to USS
Monitor.
